Description
Technical field
The invention belongs to technical field of crop cultivation more particularly to a kind of cultural methods of forage maize.
Background technique
Xinjiang is located in Eurasia innerland, and illumination is sufficient, and heat resources are abundant, and day and night temperature is big, though rainfall is rare, tool
There is matched irrigating facility, be particularly suitable for corn growth, is the generally acknowledged maximum area of Chinese maize yield development potentiality.Corn
There are the characteristics such as biomass height, the excellent and suitable ensiling of nutritive value as forage crops, development fodder maize can power-assisted currently support
Grow the development of industry, the especially development of Livestock ox, sheep industry.For active response autonomous region about Efforts To Develop animal husbandry and
The instruction of grass cultivation coordinated development, greatly developing fodder maize facilitates area's planting industry and aquaculture and society, economy and life
The coordinated development of state.
The type of forage maize is few at present, and cultivation technique falls behind, planting cost height, low output, poor quality.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of cultivation sides of the good forage maize of yield height, nutritional quality
Method.
In order to achieve the above-mentioned object of the invention, the present invention provides following technical schemes:
The present invention provides a kind of cultural methods of forage maize, comprising the following steps:
It selects preceding crop to cultivate forage maize for the plot of wheat, rape, legume, is harvested in the preceding crop
The coming year sows in spring or is poured water, ploughed when replaying, site preparation afterwards, basal dressing during the site preparation;
Forage maize seed after sunning is sowed in the first tenday period of a month in May, the application rate of the sowing is 1~1.5kg/ mus, institute
The line-spacing for stating sowing is 50~55cm, and the spacing in the rows of the sowing is 35~40cm;
After the forage maize seed sprouting, thinning final singling, one plant of a cave are carried out;
When the forage maize it is long to 4~5 leaf phase when, carry out first time intertillage, the depth of the first time intertillage is 5~
7cm;It when forage maize length to the 8 leaf phase, carries out second and intertills, described second depth intertilled is 10~15cm;
Before the forage maize jointing, urea is applied with water droplet, and carry out intertillage trickle irrigation;
Harvest when the whole strain moisture content of the forage maize drops to 65% or before frost occurs.
Preferably, the amount poured water after the preceding crop harvest is 20~30m3/ mu, the depth ploughed be 23~
27cm。
Preferably, the base manure includes well-rotted farmyard manure, Diammonium phosphate (DAP) and potassium sulfate;The applied amount of the well-rotted farmyard manure
For 3~4m3/ mu, the applied amount of the phosphoric acid diamines are 20~30kg/ mus, and the applied amount of the potassium sulfate is 4~6kg/
Mu.
Preferably, the sunning of the forage maize seed is carried out in the preceding 5~15d of sowing, and the forage maize seed dries in the air
The solarization time is 4~6h.
Preferably, described after planting using all 100~120mL/ mus of progress soil closings of that of herbicide gold.
Preferably, it is 18~22kg/ mus that the drop, which applies the amount of urea, and the irrigation quantity of the intertillage trickle irrigation is 25~30m3/
Mu.
Preferably, when forage maize length to 4~5 leaf phase, outstanding person is ploughed with herbicide and carries out weeding, the herbicide is ploughed
Outstanding amount of application is 80~100mL/ mus.
Preferably, the herbicide is ploughed outstanding application method and is sprayed for machinery.
Preferably, in forage maize length to one heart stage of leaf, pest control is carried out using trichlorphon.
Preferably, the kind of the forage maize is ' beautiful grass 3 '.
Beneficial effects of the present invention: the cultural method of forage maize provided by the invention, by selecting plot, control cultivation
Rich water in the process, pest and disease damage and etc. the output increased of forage maize that the present invention is obtained, cost reduce, and significantly
The quality for improving forage maize.Record according to the embodiment carries out forage maize using cultural method provided by the invention
Cultivation, per mu yield improves 360~576kg, and cost reduces by 5%~7%, and protein is increased to by 10.87% in forage maize
12.33%.
Specific embodiment
The present invention provides a kind of cultural methods of forage maize, comprising the following steps: selects preceding crop for wheat, oil
The plot cultivation forage maize of dish, legume, sows in spring after preceding crop harvest and carries out site preparation, during the site preparation
Basal dressing;Forage maize seed after sunning is sowed in the first tenday period of a month in May, the application rate of the sowing is 1~1.5kg/ mus, described
The line-spacing of sowing is 50~55cm, and the spacing in the rows of the sowing is 35~40cm;After the forage maize seed sprouting, between progress
Seedling final singling, one plant of a cave;When forage maize length to 4~5 leaf phase, first time intertillage is carried out, the first time intertillage
Depth is 5~7cm;It when forage maize length to the 8 leaf phase, carries out second and intertills, the depth intertilled for the second time is

1.2 fine site preparations
It pours water in time before sowing in spring after rape, wheat, legume preceding crop harvest, per acre irrigation quantity 25m3, plough is deeply
25cm harrows a kind of farm tools in time, levels land, and ploughs shallowly before broadcasting and steps on moisture in the soil, reaches defincienct in the upper and excessive in the lower.
1.3 seed cleaning
It broadcasts first 10 days, fine day is selected to carry out sunning 5h to seed, improve germination percentage, using manually or mechanically to seed progress
It is selected, remove granule, broken grain, infected seed.
2, timely and appropriate discovery is sowed
2.1 sowing time
It was completed before May 10 between positive sowing time, the replay time completed sowing before July 15.
2.2 application rate
1.5kg/ mus of application rate, line-spacing 55cm, spacing in the rows 40cm, keeping a full stand of seedings 3030 plants/acre is advisable.100mL/ mus of Jin Douer progress
Soil closing, can effectively prevent weeds in field.
3, it applies fertilizers scientifically
3.1 applying fertilizer to the subsoil
Apply high-quality decomposed cow dung or decay sheep excrement 3.5m3, Diammonium phosphate (DAP) 25kg, potassium sulfate per acre in conjunction with seedbed preparation
5kg。
The top dressing of 3.2 jointing stages
Jointing stage is the critical period of corn growth, and needs the main period of rich water.Before jointing, drop applies urea
20kg/ mus, trickle irrigation is intertilled after applying immediately, per acre irrigation quantity 28m3, reduce urea volatilization.
4, field management
4.1 thinning final singlings
After forage maize emergence, remove sick, weak, seedling, hoe uses up weeds in field, one plant of a cave in principle, be short of seedling two caves with
On stay double strains.
4.2 tillage and weeding
When coming up, 4~5 leaf phases carried out first time intertillage, depth 6cm;8 leaf phases carried out second and intertill, depth
13cm。
5, disease pest and weed is prevented and treated
5.1 chemical weed control
When forage maize grows into 4~5 leaf, outstanding to weeds cauline leaf process, dosage 100mL per acre is ploughed with herbicide,
It is uniformly sprayed with mechanical spraying machine with 18 kilometers per hour of speed per hour when fine day is calm.
5.2 pest control
Seedling stage should be noted that the prevention and treatment subterranean pest-insects such as cutworm, one leaf of seedling stage wholeheartedly when, take 90% trichlorphon 1kg, first
It after a small amount of hot water dissolving, adds water and is equably sprayed to 10kg on the cake powder or wheat bran that 100kg stir-fries, in being close to after mixing thoroughly
Late direct motion is sprinkling upon crop root, uses 5kg per acre, and prevention and treatment cutworm effect is fine.
6, it harvests in due course
It is harvested in time when whole strain moisture content drops to 65% or before frost occurs.
Forage maize kind ' beautiful grass 3 ' the plantation feature obtained using this method:
