Description
Technical field
The present invention relates to a kind of corn planting methods.
Background technique
Corn is that one of widest crops are planted in world agriculture, as Three major grain crops, because of its production abundant
" gold " industry is known as with higher use value out.In addition, corn is a kind of important green energy resource crop, it is me
One of the chief crop of state's north Biomass Energy Development, Nutrient matter up to 15%~20%, have " high energy crop " it
Claim, purposes is extremely wide, can produce high efficiency, renewable, free of contamination vehicle fuel ethyl alcohol, also capable of using as feed, sugar material, papermaking
Raw material etc..China human mortality is more, and plantation land area is small per capita, and this requires unit area corn yields to increase.
Three provinces in the northeast of China, China spring is windy, and the extreme climates such as chilling injury are frequent, vulnerable to chilling injury after emergence of corn
It influences, brings obstacle to corn planting, the final corn yield for influencing current year, therefore, effective prevention and control chilling injury is salt-soda soil
Corn planting faces and key scientific problems urgently to be resolved.
Summary of the invention
Vulnerable to chilling injury when the invention aims to solve three provinces in the northeast of China's spring emergence of corn, corn growth is caused
The suppressed problem low with corn yield, and a kind of corn planting method that low-temperature resistance damages to plants caused by sudden drop in temperature is provided.
A kind of corn planting method that low-temperature resistance damages to plants caused by sudden drop in temperature, is completed by the following steps:
One, site preparation:
Ground is flattened using agricultural machinery, then by crops stalk crushing to 500 mesh~1000 mesh, then uniform fold is to smooth soil
The soil layer surface on ground, then turned over, ploughed depth is 15cm~20cm, and agricultural crop straw is embedded under topsoil, is finally carried out
Prepartion of land；
Two, seed treatment:
1., to corn seed carry out it is selected, remove disease pest kind, residual kind, mould kind and immature kind, obtain selected maize seed
Son；
2., selected corn seed is immersed in corn seed treatment fluid, being subsequently placed in temperature is at 40 DEG C~45 DEG C
1h~3h is impregnated, then corn seed is pulled out and is dried in the shade, the corn seed that obtains that treated；
Step 2 2. described in corn seed treatment fluid by following weight percent material composition: 5-ALA
400~500ppm, more than 0.1%~0.3% bacterium zero, 0.1%~0.9% sodium sulphate, 8%~10% Na Shi trimly send out inducer,
15%~20% polyethylene glycol, 8%~15% amino acid, surplus are water；
3., prior to seeding 5 days~12 days, current strength be 1.0A under conditions of, use plasma seed treatment
Machine is obtained to treated twice of corn seed continuous processing to seeding corn seed；
Three, it applies fertilizer:
Organic fertilizer and inorganic fertilizer are spread fertilizer over the fields in the earth's surface leveled land, then organic fertilizer, inorganic fertilizer and topsoil soils are mixed,
Rotary tillage, ridging is carried out again；
The mass ratio of organic fertilizer described in step 3 and inorganic fertilizer is (1200~1300): 20；
Four, it sows:
By step 2 3. obtained in sow to seeding corn seed, by ridge planting, sow 3~5 ridges, empty 1 ridge is not
Sowing, depth is 8cm~13cm when sowing, and 1~2 corn seeds are sowed in each hole, and hole is away from 18cm~25cm, and Gansu Province is away from 25cm
~40cm；
Five, cold-resistance agent is prepared:
1., weigh the sucrose solution that 3 parts~5 parts mass fractions are 2%~5%, 6 parts~7 parts quality point in parts by weight
Count the humic acid solution for 2%~5%, the ethylene glycol solution that 3 parts~5 parts mass fractions are 10%~20%, 2 parts~3 parts matter
Measure score be 0.03%~0.08% salicylic acid solution, 1 part~3 parts mass fractions be 4%~5% dimethyl sulfoxide it is water-soluble
The di(2-ethylhexyl)phosphate that proline solution that liquid, 4 parts~6 parts mass fractions are 5%~10%, 3 parts~5 parts of mass fractions are 5%~8%
Hydrogen potassium solution and 0.05 part~0.5 part thickener；
Step 5 1. described in thickener be Sodium Polyacrylate；
2., by weighed 3 parts~5 parts mass fractions in step 1 be 2%~5% sucrose solution, 6 parts~7 parts quality
Ethylene glycol solution that humic acid solution that score is 2%~5%, 3 parts~5 parts mass fractions are 10%~20%, 2 parts~3 parts
The dimethyl sulfoxide that salicylic acid solution that mass fraction is 0.03%~0.08%, 1 part~3 parts mass fractions are 4%~5% is water-soluble
The phosphoric acid that the proline solution and 3 parts~5 parts of mass fractions that liquid, 4 parts~6 parts mass fractions are 5%~10% are 5%~8%
Dihydro potassium solution and 0.05 part~0.5 part thickener are uniformly mixed, and obtain cold-resistance agent:
Six, in emergence of corn to 3 leaf phases, cold-resistance agent is diluted to after mass fraction is 20%~25% and carries out blade face spray
It applies, the amount of spraying is 50mL/m2~100mL/m2；
Seven, in 4 leaves~7 leaf phases, cold-resistance agent is diluted to after mass fraction is 30%~40% and carries out foliage-spray, is sprayed
Amount is 100mL/m2~200mL/m2；
Eight, compound liquid medicine is prepared:
Corn resistance to lodging agent, fungicide, insecticide and water are uniformly mixed, compound liquid medicine is obtained；
The mass ratio of corn resistance to lodging agent, fungicide and insecticide described in step 8 is (10~13): (10~18): (8
~14)；
The mass ratio of corn resistance to lodging agent and water described in step 8 is (10g~13g): (35kg~45kg)；
Nine, compound liquid medicine is sprayed:
When corn growth is to 8~12 leaf, compound liquid medicine is subjected to foliage spray, fountain height is 30kg~90kg；
Ten, top dressing:
Pour water during corn growth 2 times~3 times, and top dressing is primary after jointing, topdressing amount be per acre 700kg~
The decomposed poultry muck of 800kg, nitrogen-phosphorus-potassium weight proportion are corn fertilizer 12kg~15kg of 32:10:8；It is taken out in corn male
First 7 days~10 days top dressing 8kg~13kg ammonium sulfate again per acre；
11, field management, until harvesting corn.
The present invention include it is following the utility model has the advantages that
One, the present invention is by crops stalk crushing to 500 mesh~1000 mesh, then uniform fold is to the soil layer table leveled land
Face, then turned over, ploughed depth is 15cm~20cm, and agricultural crop straw, which is embedded under topsoil, can reduce soil hardening, together
When the temperature of soil can be improved, realize and move back woods returning to the field；
Two, the present invention is low for northern spring ground temperature, corn seed be easy powder seed, emergence not entirely, survival rate is low and seedling gesture
Weak problem has developed corn seed treatment fluid, using corn seed treatment fluid prepared by the present invention to selected corn seed into
Row processing, can guarantee the germination percentage of corn seed, compared with the operation for not carrying out step 2 of the present invention, the germination of corn seed
Rate significantly improves；With strengthening root strong sprout and increase corn resistance after step 2 of the present invention handles corn seed
Effect；
Three, cold-resistance agent prepared by the present invention is sprayed on corn seedling blade face, can be formed on corn seedling blade face
One layer of heat preservation film reduces moisture evaporation, protects heat, enhances the ability that corn seedling resists low temperature, while having for jade
Meter You Miao provides the function of nutrition, enhances absorption of the corn seedling to nutrients such as phosphorus potassium, improves corn seedling to adverse circumstance
Adaptability alleviates influence of the low temperature to current year corn yield；
Four, present invention science selection corn resistance to lodging agent, fungicide, insecticide, single Pesticide use is changed to be used in combination,
And suitable spraying time point is selected, and it is primary to spray, corn capacity for the resistance to lodging can be effectively improved, Corn diseases and insect pests can be effectively prevented,
