Water-saving effect experimental study
5 groups of experimental groups, 1 group of control group and totally 7 groups of 1 group of blank group are set, 200g aeolian sandy soil is separately added into 7 and identical open is held
In device, it is then separately added into water-retaining type liquid suspension fertilizer 10ml made from embodiment 1-5 in experimental group, is added in control group
Fertilizer is not added in liquid suspension fertilizer 10ml made from comparative example 1, blank group, mixes, is then separately added into 50ml in 7 groups
Water, so that each group soil saturation, weighing, and place and tested under field conditions (factors), the fluid loss of weighing measurement daily, when continuing
Between 4 days, the results are shown in Table 1.
Influence of the 1 water-retaining type liquid suspension fertilizer of table to soil fluid loss
As shown in Table 1, after natural evaporation 4 days, moisture is evaporated the soil moisture of blank group substantially, compares blank group, control
Organize Water-saving effect well, and the Water-saving effect of experimental group is then very significant, this is because in the liquid suspension fertilizer of experimental group
Tea stalk powder after being added to alkali process, can promote the formation of soil aggregate structure, be obviously improved Water-saving effect.
Influence experiment of the water-retaining type liquid suspension fertilizer to cucumber growth
The village Jian Tian 3 ~ July in 2017 near Fujian Province Agriculture InstituteSoil and Fertilizer Institute is tested to carry out.This test
Using 72 hole plug media nursery, sowing on March 1st, 2017, on April 1st, 2,017 three leaf of cucumber seedling wholeheartedly when be colonized, use
The basin alms bowl of 20 ㎝ high of diameter, 20 ㎝, every basin fill matrix 4kg(peat soil: vermiculite=1:1), every group of 10 basins are in triplicate, random to arrange
Column.Test 6 groups of experimental groups of setting and 1 group of control group, experimental group apply the suspension fertilizer of water-retaining type liquid made from embodiment 1-5 respectively
Liquid suspension fertilizer made from material and comparative example 1, control group use conventional fertilizer application, and management measure is consistent, irrigation amount is the same.Every group
When containing the melon phase, (on June 1st, 2017) selects 5 plants of measurement cucumber water content, soluble sugar content, Vc content, crude protein to contain at random
Amount and chlorophyll content, the results are shown in Table 2.
Influence of the 2 water-retaining type liquid suspension fertilizer of table to cucumber growth
Apply water-retaining type liquid suspension fertilizer of the invention, embodiment 1-5 and comparative example 1 the cucumber water content for containing the melon phase, can
Dissolubility sugared content and Vc content, chlorophyll content are above control group, and crude protein content is declined, and the effect of embodiment 1-5
Fruit is better than comparative example 1.
It is preferred that comparative example 1, embodiment 1 are carried out as a control group as test group and conventional fertilizer application about the application present invention
Water-retaining type liquid suspend the research of influence of the fertilizer to different depth soil layer absolute water content.Using high 350mm, internal diameter 72mm
PVC manage (bottom seals), according to 1.1 gcm- 3Field soil bulk density it is horizontal, 300 mm soil is calculated
Column need to load the quality of dry ground, load weighted soil is packed into the Simulated soil columns that pvc pipe forms about 300mm, then in earth pillar table
The filter paper of a diameter 70mm is placed in face, to guarantee that surfacing and moisture can equably be permeated into earth pillar when adding water,
Liquid feeding state suspension fertilizer 80ml adds water to adjust 60% (how much foundation soil of amount of water of earth pillar water content to field saturation moisture capacity
The level of 60% field saturation moisture capacity of filling soil calculates in column), after standing for 24 hours, remove filter paper.27 are made altogether
The above specification earth pillar and 5 days after application, 10 days, 15 days different soil depth progress soil basis determinings.
Soil absolute water content=(wet soil weight-drying soil weight)/dry ground weight * 100%
Influence of the 3 water-retaining type liquid suspension fertilizer of table to different depth soil layer absolute water content
The result shows that: water-retaining type liquid suspension fertilizer of the invention is applied, soil moisture content is higher than control group.It suspends in application fertile
5 days afterwards, the water content of test group and control group in 0 ~ 10cm soil layer depths reached significant difference, but in 10 ~ 20cm and 20 ~ 30 ㎝
The water content difference at place is not up to the level of signifiance, wherein with the water content highest of embodiment 1.10 days after application suspends fertilizer, examination
It tests water content of the group in 0 ~ 10cm soil layer depths and is significantly higher than control group, be the aqueous of embodiment 1 in different soil depth
Amount is higher than the water content of comparative example 1, and the two significant difference.15 days after application suspends fertilizer, the Water-saving effect of test group is still
Well, it is significantly higher than control group, at 10 ~ 20 ㎝, the water content of embodiment 1 is higher than control group by 45.7%.
The foregoing is merely preferable case study on implementation of the invention, all equivalent changes done according to scope of the present invention patent
With modification, it is all covered by the present invention.
