Description
Technical field：
The present invention relates to agricultural plantation technology field, and in particular to a kind of planting of sweet corn wet soil germination accelerating method.
Background technology：
Corn, belong to one of China staple crops.With the improvement of corn variety, corn is used as vegetable in recent years
Dish is cooked in assorted dish, the excellent edible quality so that sweet taste is dense, kind thin skin, fragrance, sweet tea are crisp etc. and be loved by consumers.
The highly shrivelled shrinkage of sweet corn seeds, vitality is weak, and the effective supply of plumule nutrient is lacked when Seed sprouting germinates
And making growth of seedling weak, the live germination and emergence rate of large area only reaches 50% or so, disconnected ridge outstanding problem of being short of seedling, and plants in addition
Sub- price is higher, affects the enthusiasm of Cotton Varieties by Small Farming Households to a certain extent.Therefore, it is to improve germination using wet soil vernalization new technology
Effective measures.
The content of the invention：
The technical problems to be solved by the invention are that providing one kind can make large area insemination and emergence rate reach more than 95%
And regularity reaches more than 90% so as to effectively solve the problems, such as the planting of sweet corn wet soil vernalization on the live disconnected ridge that is short of seedling of large area
Method.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of planting of sweet corn wet soil germination accelerating method, comprises the following steps：
(1) vernalization disk makes：Vernalization disk, vernalization disk length of side 50- are made from the good plastic material of nontoxic and hardness
60cm, deep 10cm, and prick 1 0.5cm every 5cm trying to get to the heart of a matter2Passage；
(2) prepared by seed dressing soil：Thin loam is taken, granularity 2-3mm particle is made after impurity elimination is sieved, is subsequently placed in 70-80
12h is dried in DEG C baking oven, adds seed dressing additive, and adds water to be stirred, the water content of regulation seed dressing soil reaches 65-
70%；
(3) wet soil vernalization：The evenly laid out 3-4cm of soil will be dressed seed in vernalization disk, and sweet corn seeds are spaced one by one and put
It is placed on seed dressing soil, spacing 1-2cm, then 2-3cm seed dressing soil is covered on seed, vernalization disk is then put into temperature 25-30
DEG C, in humidity 55-60% germinating cabinet, vernalization disk both ends, which are buckled, to be hung on vernalization support, while ensures that vernalization disk is tried to get to the heart of a matter distance ground
Face highly reaches more than 30cm；
(4) kind is taken in good time：Gently the thick soil layers of 2-3cm on vernalization disk are pushed aside after 2-3 days, shape of sprouting will be in scuppit
The sweet corn seeds of state take out together with soil layer thick seed bottom 2-3cm, and are seeded into immediately in crop field.
The weight ratio of dried thin loam and seed dressing additive is 10-15 in the step (2):0.5-1.
The seed dressing additive is mixed by multiple functions auxiliary agent, and specific mass fraction proportioning is：Depickling furfural dregs
3-5 parts, vinasse 2-3 parts, sugarcane sugar residue 0.5-1 parts, sodium cellulose glycolate/polyglutamic acid compound 0.5-1 parts, fresh bamboo powder
0.1-0.2 parts, hydrophily volcanic ash 0.1-0.2 parts, magnesium stearate 0.05-0.1 parts, calamine stone 0.05-0.1 parts；The rice
The water content control of vinasse is in 25-35%.
The sodium cellulose glycolate/polyglutamic acid compound is multiple by sodium cellulose glycolate and polyglutamic acid
Close and be combined under promoter effect, its specific preparation method is：Into sodium cellulose glycolate add HPMA and
Rilanit special, 110-115 DEG C of insulation grinding 15min is warming up to, polyglutamic acid and PVPP is added, continues
110-115 DEG C of insulation grinding 30min, then continues at sealing and standing 1h in 0-5 DEG C of environment, and adds boiling water, is sent after being sufficiently mixed
Enter in spray dryer, dry gained particle and micro mist is made through micronizer, produce sodium cellulose glycolate/polyglutamic acid
Compound.
The sodium cellulose glycolate, HPMA, rilanit special, polyglutamic acid and PVPP
Weight ratio is 10-15:0.5-1:0.1-0.5:5-10:0.5-1.
The hydrophily volcanic ash is to be formed by volcanic ash through hydrophilic modifying, and specific method of modifying is：By volcanic ash through true
Pneumatics shortens into and micro mist is made using micronizer after block, is re-fed into the nanometer that granularity 30-50nm is ground into nanon ball-mill
Powder, poloxamer and N hydroxymethyl acrylamide are then added, and be warming up to 115-120 DEG C of insulation grinding 30min, most passed through afterwards
Nanon ball-mill is ground into granularity 15-20nm nano-powder.
The weight ratio of the volcanic ash, poloxamer and N hydroxymethyl acrylamide is 5-10:0.5-1:0.1-0.3.
The beneficial effects of the invention are as follows：
(1) " trying to get to the heart of a matter by taking and pricking 1 0.5cm every 5cm2Passage " and will " vernalization disk both ends, which are buckled, to be hung over
Ensure that vernalization disk is tried to get to the heart of a matter simultaneously on vernalization support and reach more than 30cm apart from ground level " measure, improve sweet corn seeds and urge
Air permeability during bud, prevent from making FCR de-vitalizing seed because temperature is too high inside soil layer；
(2) by seed dressing soil " be placed in 70-80 DEG C of baking oven dry 12h " processing, to seed dressing soil carry out pesticide and disinfectant,
Kill the worm's ovum carried in seed dressing soil and germ；
(3) by the nutrition system of the use for additive of dressing seed, on the one hand abundant seed dressing soil, on the other hand play excellent
Soil layer moisture-keeping function；
(4) it can reach the large area insemination and emergence rate of corn using corn wet soil germination accelerating method of the present invention
More than 95%, and regularity reaches more than 90%, so as to effectively solve the problems, such as the live existing disconnected ridge that is short of seedling of large area, reduces
The economic loss of planting household and the reduction increased workload because filling the gaps with seedlings.
