(6) gather in the crops
By the end of August-the beginning of September carries out spring corn results.
(2) implantation methods of summer corn
(1) Fruit variety and seed treatment
Corn seed should choose the principle with the high-grade maize Fruit variety of the resistance to dense planting of stable high yield potentiality of this ecological region planting applicable, and one is stable yields, and two is high yields, and three is high-qualitys.
Seed treatment is carried out before broadcasting, broadcast front 1-2d to bask seeds to corn seed, to improve potentiality of seed and germination rate, select the seed coat agent with bactericide and insecticide double effects simultaneously, effectively to prevent and treat soil insect and maize head smut, strive that realizing one broadcasts full stand.
(2) sow
Sow to the middle ten days in early June, medicament should be used before emerging after corn seeding and carry out soil and close weeding.
Type of seeding, high liquid manure ground adopts corn wide-and narrow-row culture technique, is generally 40+80 or 50,+70 two kinds of size line-spacings, uses the fertile 127.5kg/hm of sulfenyl corn dedicated port at seeding time
2make mouth fertilizer to apply with seed, note seed manure isolation, burn seedling with unburned kind.
(3) field management
1) seedling management
One is early look into seedling to fill the gaps with seedlings, to ensure full stand.Transplant when seedling 3-5 leaf, select strong sprout, band wet soil entirety is transplanted, and below 3 caves that are short of seedling, in the one or both sides, place that are short of seedling, stays the two strain of seedling.Two is thinning final singlings.Between three leaves, five leaves are fixed, gradation thinning.Thinning principle be " go weakly to stay strong, preventing or cure a disease, it is strong to stay, little stay large, " generally keep a full stand of seedings 6.75 ten thousand-8.25 ten thousand strains/hm
2.
2) apply fertilizers scientifically Guan Shui
Seedling stage the rational application of fertilizer, after final singling to the shooting stage according to the growth of cereal crop seedlings, soil fertility determine dressing time, general Nitrogen Top Dressing 150kg/hm
2, the plot of three class seedlings, non-basal dressing or seed manure, the plot of low-lying humidity and interplanting corn etc. can suitably heavily chase after, and impel Winter wheat, nurturing staff.
The corncob phase to nourish and grow and reproductive growth is gone forward side by side the phase, and increasing rapidly the infiltration rate of nutriment and quantity, is the important period that corn topdresses, Nitrogen Top Dressing 300kg/hm
2.
The primary management role of flower grain phase is the good growing environment of solid creation of pollinating, and improves plant photosynthetic efficiency, extends the physiologically active of root and leaf, prevent early ageing and lodging, and to reach, grain is heavy, grain is full and the object of high yield.Therefore, should granules application be fertile ingeniously, impose around phase at female tassel blossom and attack granulated fertilizer urea, 225kg/hm
2, the principle that granulated fertilizer is used is " should be early not slow ".Plant appearance is good, take off light phenomenon without early ageing, leaf look dark green field can Shaoshi.To pour water in time if this phase runs into sky drought, when field capacity is more than 80%, should draining be noted.
3) change control in good time
The corn typhon phase uses healthy and strong agent 150mL/hm
2to water 300kg full field spraying, while restraining the growth of seedlings, improve the resistance of corn, contribute to the output improving corn.
4) artificial emasculation supplementary pollination
Emasculation should be carried out when tassel has just been extracted out and not yet bloomed loose powder, should take blade out of too early, affect photosynthetic area, crosses late tassel and to bloom loose powder, affect emasculation effect, generally take the method for interlacing emasculation.Interlacing emasculation can reduce the bald point of fruit ear in conjunction with artificial pollination, lack grain, generally can increase production 10%.
(4) sick worm rat plague control
Seedling stage prevents and treats cutworm in time, with 2.5% deltamethrin milk oil, 2000 times of liquid after emerging, sprays seedling at dusk capable, or is spread on the capable both sides of seedling with 50% phoxim emulsifiable concentrate sand cutting.
Corncob phase disease is the disease such as leaf blight, helminthosporium maydis, brown spot mainly, and insect pest is the insect such as corn leaf aphids, corn borer, cotton sandfly worm mainly.Leaf blight, helminthosporium maydis can dilute 500 times with 50% carbendazol wettable powder and spray, and spray 750-1050g/hm
2, 7-10d sprays 1 time, connects spray 2-3 time.For insect pest, generally taking green bio prevention and control to be main, chemical control is auxiliary prophylactico-therapeutic measures, and biological prevention and control can adopt oophagous trichogrammae and BT powder to prevent and treat; Chemical control 3% Furadan 7.5kg/hm
2, or 3% phoxim granule 15.0-22.5kg/hm
2lose the heart; With high-quality Imidacloprid or Acetamiprid chemical control 1 time when the fringe phase, aphid occurred heavier.
Corn later stage aphid damage should in time with the 1000 times of liquid spraying controls of 10% imidacloprid wettable powder; Poison bait with 0.05% zinc phosphide poison bait, can be added a small amount of sesame oil by protection against rodents, mixes and is sprinkling upon the often movable place of mouse, throw in 2-3d continuously.
(5) gather in the crops in good time
Extending the pustulation period in the corn growth later stage is the important channel of improving output.80% of yield per unit area is only defined during the jaundice of corn ear bract; the output of 20% is also had to need again through the maturation of about 15d; when fruit ear bract bleach withered pine, seed milk-line disappear, be the best period of harvest corn when seed base portion occurs that black layer, moisture content of kernels are below 35%.According to testing data, corn starts, to full ripening stage, to receive 1d every night from wax ripeness, and thousand kernel weight can increase 3-4g, volume increase 75-105kg/hm
2, the corn kernel of postponement results is full, even, granule, blighted grain reduce, and moisture content of kernels is lower, and protein content is high, and commodity is good, is also convenient to threshing and stores.
| Vegetative period | Water consumption | Output | |
| Summer corn+winter wheat | 95-100d (summer corn) | 750-850mm | 500-700kg/ mu |
| Spring corn | 118-130d | 400-700mm | 750-800kg/ mu |
Above 2 embodiments of the present invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
