Two, Testing index and method
1, the measurement and method of mixed-matrix physical behavior index
Unit weight, total porosity, aeration porosity, the water-holding porosity of mixed-matrix, the measurement of air water void ratio is with reference to even
The million bright each measurement of saturation extraction are repeated 3 times, to reduce error.
(1) method for measuring of mixed-matrix unit weight
The height and internal diameter for measuring cutting ring, calculate volume (v), and cutting ring weight (a) is weighed on electronic balance.It will mix
It closes matrix to pile up, is highly more than the height of cutting ring, the sharp one end of cutting ring is vertically pressed into soil, can not be rocked from side to side.So that
The natural structure of mixed-matrix is not destroyed, until in cutting ring all indentation mixed-matrix.Then with scuppit by cutting ring from mixing
It is dug out in matrix.And carefully scabbled along cutting ring edge trimming using pocket knife, cut off extra soil, both ends capping.Weigh ring rapidly
The weight (e) of knife and mixed-matrix in cylinder, calculates weight in wet base (f), by taking out a part of soil in wet soil by the difference of (a) and (e)
Water content (w) is measured, then calculates whole dry weights of entire cutting ring, thus calculates the soil weight.Mixed-matrix unit weight=f (1-w)/
v。
(2) measurement of mixed-matrix total porosity
Since the density measurement of mixed-matrix is relatively complicated, can be estimated according to following method：With 1 known volume
(V) container claims its weight (W1)；It fills it up in this embodiment and needs matrix to be measured, be re-weighed (W2)；Then matrix will be filled
Container impregnate diel in water, weigh (W3).Should be allowed when soaking water level be higher than container top, if matrix compared with
Gently, the gauze of wrapping is removed when should be bandaged, but weighed with one piece of gauze at the top of container, this is calculated by following formula
The total porosity of kind matrix.
Total porosity calculation formula is：Total porosity (%)=(1- unit weights/density) × 100%；Total porosity (%)=
[(W3-W1)-(W2-W1)]/V × 100%.
(3) aeration porosity, the measurement of water-holding porosity and air water void ratio
Measure mixed-matrix gas and water ratio, need to first measure its ventilating slit and water holding hole respectively shared by ratio.It measures
Method is as follows：The container of 1 known volume (V) is taken, after being packed into solid matrix, after measuring its total porosity according to the method described above,
The moistening gauze (W4) of one known weight of upper opening of container is encased again, container upside down, allows the moisture in container to flow out, puts
2h is set, until when not having moisture exudation in container, claims its weight (W5), is calculate by the following formula water holding hole and ventilating slit
Shared ratio (unit is measured with total porosity).
Water holding hole (%)=[(W5-W4-W2)/V] × 100%；Matrix gas-water ratio=ventilating slit (%)/water holding hole
(%)；Ventilating slit (%)=[(W3+W4-W5)/V] × 100%.
2, the measurement of mixed-matrix chemical property index
Matrix acid-base value (pH value), conductivity (EC values) all use soil ratio (5: 1) extraction；Matrix acid-base value (pH
Value)：PH test paper measures；Conductivity (Ec values)：Portable conductivity gauge measures.
3, the measurement of plant growth index
Following data is determined successively with the progress of experiment
(1) in the matrix of each substrate composition seed germination percentage, sprout time；
(2) height of seedling of plant, ground diameter in the matrix of each proportioning after emerging.
Three, statistical analysis technique
Experiment carries out variance analysis and Multiple range test with software to observing the data recorded and analyzed and obtain.
Four, test result
1, the physicochemical character of different mixed-matrix proportionings
Sour physicochemical character is carried out to mixed-matrix to measure, measurement result is shown in Table 2.
Table 2：The physics and chemical property of different substrates proportioning
The physical behavior of different ratio matrix
Unit weight influences the stability of plant setting, and the more big then plant of unit weight is more stable but excessive, can influence the suction of plant
The growth of water and root system.As known from Table 2, this unit weight ranging from 0.34~0.71g/ for testing prepared different substrates processing
cm3, 0.98g/cm is compareed far below soil3, only the 34.69%~72.45% of the soil weight.Wherein T1 is held in 9 groups of processing
Weight is maximum, is 0.71gcm3, the reason is that the proportion of honeycomb cinder is maximum in T1, reached 70%.It follows that bee in formula
The proportion of nest cinder is bigger, then the unit weight of this group of matrix is bigger.It is low to be formulated unit weight, is more saved into transplanting, transport
This, facilitates transfer.What total porosity reflected is the void condition of matrix, big (such as total porosity of perlite, vermiculite of total porosity
All 95% or more), illustrate that matrix is loose, big compared with amount that is light, accommodating water and air, is conducive to the healthy growth of root system, but plant
Object easily floats, and the effect of fixed plant is poor；Conversely, then matrix is solid, the capacity of heavier, air and moisture is small, it is unfavorable for root system
Stretching, extension, feed flow number need to be increased, and the porosity of matrix is determined by the content of each matrix.As shown in Table 2, pass through matrix
The physical property of matrix can be improved by being used in mixed way, and the porosity of test matrix is all bigger than soil, illustrate each test group matrix all
Be conducive to the sprouting of seed and the growth of plant.The air water void ratio of matrix can reflect the state of gas and water between matrix, if
Air water void ratio is big, illustrates that matrix air capacity is big, and water-holding capacity is small, and water storage power is weak, and aeration is with regard to strong；Conversely, air containment
It is small, and water-holding capacity is big.The air water void ratio of usual matrix, which should be maintained at 25%~66%, to be advisable, the air water void ratio of each experiment
All within the scope of this.Known to comprehensive analysis：The unit weight of mixed-matrix, ventilation, water holding aspect are more conducive to plant than it in soil
Growth.In addition, honeycomb cinder in this experiment is burning waste, raw material sources are extensive, and contain abundant full N, quick-acting
P, K and trace element are proper test matrix.The substrate culture application effect is good, solves the processing of waste
Problem, while high-quality matrix also is provided for soilless culture, improve the utilization ratio of natural resources.
The chemical property of different substrates proportioning
The height of soil acidity or alkalinity directly affects the property of soil, to influence the growth and development of flowers, crosses alkali or peracid
Soil it is all unfavorable to the growth of flowers, most of flowers pH value be 6.0~7.0 subacidity soil environment under grow it is most suitable
Preferably.Soil, which crosses alkali or peracid all, can influence the solubility of mineral element, make certain nutrients become the state of nonabsorable from
And some flowers is caused to be easy to happen nutrition nutritional deficiency disease, even result in plant death.As can be seen from Table 2, the pH value respectively handled
It is 6.8~7.5, all in the range of near neutral, is relatively suitble to Lisianthus growth and development, and the content of peat has influenced soil
The PH of earth, the more big then PH of content is smaller, and wherein T2, T3, T6 are slightly sour environment, are more suitable for Lisianthus in contrast
Growth.Conductivity is small, it was demonstrated that soluble organic fraction is less contained in soil or matrix, can not provide the enough of plant normal growth
Nutrient；Conductivity is big, illustrates more without soluble organic fraction contained in native formulation media, facilitates being absorbed and utilized for plant, to
Promote the growth of plant.For the conductivity of all processing all significantly more than control, the conductivity of each matrix treatments is 34.9~63.1 μ
S/cm.By table 1~2 it is found that with honeycomb peat and cinder content in formula increase, conductivity (EC values) also increases, says
Soluble organic fraction contained by this bright 2 kinds of matrix itself is more, therefore does not need in plant growth initial stage to apply excessive fertilizer.
2, the influence that the physicochemical character of different mixed-matrix proportionings grows Lisianthus
It is measured, and combined obtained by the growth indexes of physicochemical property and vegetable material to mixed-matrix
Data carry out comprehensive analysis, obtain every physical and chemical index of suitable Lisianthus growth, germination percentage, height of seedling, ground diameter index be shown in Table
3。
Table 3：The growth indexes of Lisianthus in different substrates
| Processing | Germination percentage/% | Average height of seedling/cm | Average ground diameter/cm |
| T1 | 63.6% | 1.31 | 0.31 |
| T2 | 89.7% | 1.68 | 0.31 |
| T3 | 68.5% | 1.59 | 0.31 |
| T4 | 83.6% | 1.67 | 0.33 |
| T5 | 71.3% | 1.64 | 0.33 |
| T6 | 98.5% | 1.98 | 0.33 |
| T7 | 90.7% | 1.88 | 0.32 |
| T8 | 97.2% | 1.96 | 0.31 |
| T9 | 89.0% | 1.72 | 0.31 |
| CK | 68.0% | 1.55 | 0.30 |
Different substrates are with the influence for comparing Lisianthus germination
It is optimal set, the germinating time and germination percentage of T6 is all than it by table 3~4 it is found that T6 germination percentages are up to 98.5%
He organizes morning.Reason is that air water is more moderate earlier for germination, has good ventilative, permeable and water-retaining property, matrix can be made to keep wet
Profit state is conducive to bulb germination.The total porosity of T6 is 63.67%, ventilating slit 23.55%, and water holding hole is
40.12%, air water void ratio is 0.59, and acid-base value (pH value) is 6.9, and conductivity (EC values) is 38.8 μ S/cm.T8 is preferable, always
Porosity is 68.11%, ventilating slit 24.54%, and water holding hole is 43.57%, and air water void ratio is 0.57, acid-base value
(pH value) is 7.0, and conductivity EC is 44.5 μ S/cm.The germination rate of other processing in addition to T1 is above garden mould control CK, T1
Minimum germination percentage is to have reached 70% because the content of honeycomb cinder is higher, caused the acid-base value of mixed-matrix higher.Thus may be used
Know, the environment of meta-alkalescence is not suitable for the sprouting of Lisianthus seed.By table 4, table 2 it can also be seen that the time longest that T5 sprouts, former
Air containment because being matrix is smaller, is unfavorable for seed sprouting, but soluble organic fraction contained in formula is more, is inhaled convenient for plant
It receives and utilizes, promote plant growth, this compensates for the insufficient defect of air content to a certain extent, therefore the germination rate of the group is simultaneously
It is not minimum.In summary：When general porosity is 63.67%, air water void ratio is 0.59, when acid-base value is subacidity, is had
Conducive to the growth after the sprouting and sprouting of the seed of Lisianthus.

Different substrates are with the influence for comparing Lisianthus Seedling height
Reason average height of seedling is according to size discharge sequence everywhere：T6, T8, T7 ＞ T9, T2, T4, T5 ＞ T3 ＞ CK ＞ T1, variance
Analysis result is shown in Table 5.
5 Lisianthus height of seedling variance analysis of table
It can be known by table 5：(1) throughout Seedling height situation is worst to T1 plant in reason group, less than the growth indexes of control,
It is unfavorable for Lisianthus growth.(2) it grows in best three groups of T6, T7, T8, height of seedling difference is little, but T7 grows unstable, reason
Be T7 conductivity it is minimum (31.9 μ S/cm), enough nutrients cannot be provided for plant.(3) aeration porosity of T2, T4, T5
Respectively 15.55%, 12.60%, 13.81%, and the ventilating slit of T9 is 15.85%, illustrates the air containment ratio of T9 in addition
Several groups big, the supply of oxygen is more sufficient, therefore average height of seedling ratio T4, the T5 high of T9.(4) the bad reason of T3 growing ways may be
It is all less than normal in its unit weight (0.38g/cm3), total porosity (48.81%), illustrate the excessively loose of matrix, the effect of fixed plant
It is poor.(5) in addition to T1, each plant strain growth that handles is superior to control group CK, illustrates the physicochemical character of mixed-matrix in contrast more
It is suitble to plant growth.Through Multiple range test, 6 are the results are shown in Table.
6 Lisianthus average height of seedling Multiple range test of table
As shown in Table 6, T6 is to be most suitable for Lisianthus growth, and matrix unit weight is 0.36g/cm3, and total porosity is
63.67%, ventilating slit 23.55%, water holding hole is 40.12%, and air water void ratio is 0.59, and conductivity (EC values) is
38.8μS/cm.Lisianthus upgrowth situation in garden mould compares CK is poor, and compared with mixed-matrix, the physicochemical character of soil is poor,
Porosity is smaller, poor air permeability, and Lisianthus requires soil or matrix loose ventilative, and water holding capacity is strong.Therefore relative to biography
The earth culture of system carries out the transportation problem that cultivation is not only to solve flowers using mixed-matrix, it is often more important that is plant growth
Provide a more suitable environment.
Different substrates are with the influence for comparing Lisianthus Diameter growth
Lisianthus ground diameter the results of analysis of variance is shown in Table 7.The average ground diameter difference very little that different substrates are matched, the results of analysis of variance
Show that the influence that different substrates proportioning generates the Diameter growth of Lisianthus is not notable, therefore ground diameter can be not as matrix
The foundation of formulation optimization screening.
7 Lisianthus ground diameter variance analysis of table
Five, conclusion
In 9 processing, in general from the indices of plant, optimal case is T6 (perlites: peat: vermiculite: honeycomb
Cinder 2: 3: 1: 4), this group of germination percentage highest (98.5%), and it is 12 days that germinating time is also most short, average height of seedling highest
(1.98cm).By analysis, T6 and other processing differences are apparent.It is 0.36g/cm to be relatively suitble to the unit weight of Lisianthus growth3, total hole
Porosity is 63.67%, ventilating slit 23.55%, and water holding hole is 40.12%, and air water void ratio is 0.59, pH value 6.9,
Conductivity (EC values) is 38.8 μ S/cm.
During soilless culture, plant strain growth is influenced maximum to be exactly acid-base value (pH value), the hole for being matrix
Degree, gas-water ratio and unit weight, and to the growth combined influence of plant.The acid-base value of matrix has to the growth needs for being suitble to plant,
Otherwise it just will appear situations such as upgrowth situation is bad；The unit weight of matrix should also be suitble to, and unit weight is excessive, and seed is difficult to sprout, too small
It is then very big to the stability influence of plant；And porosity and gas-water ratio are also one side important in growing process, directly
The content of air in matrix is influenced, lack of air can then hinder the growth of plant.Soilless culture can press various single-matrixes
It is mixed according to various ratios, to reach certain specific purposes, certain disadvantages of single-matrix can also be overcome, make its physicochemical character
It is improved, can more effectively coordinates the contradiction between water, fertilizer, gas, be more advantageous to plant growth.
