Abstract

The invention discloses a seedling transplantation method for summer corn. The seedling transplantation method is characterized in that field which is sheltered from wind, faces the sun and is near land for growing crops is selected as a seedbed; 7-10 square meters of seedlings can be transplanted for one mu of land for growing crops generally; paper bags or nutrition pots of which the height is about 9 cm, and the diameter is about 5 cm in specification are adopted; 5000 paper bags or nutrition pots are adopted per mu; 50 kg of fine earth and 50 kg of thin excrement are mixed; 5 kg of K2SO4 compound fertilizer is added to mix uniformly for bagging; the seedlings are raised 10-15 days before the flower season of preceding crops; coating crossbred fine seeds which are high in quality and yield and moderate in maturation stage are selected and used; 1 piece seeding is sowed in per bag when sowing; irrigation is conducted instantly after the sowing; soil dryness degree of the nutrition bags is noticed at the same time to supply water promptly and maintain moist; cultivation is conducted when the seedlings grow to 3-4 leaves; when growing the seedlings, plastic thin films are arranged at the bottom; the seedling bags are closed up and straightened one by one. After adoption of the technical scheme, a seedling cultivation technology conducting seedling raising first and transplantation then, and the yield of the summer corn can be improved by 30 percent.

Description

A kind of method for culturing and transplanting seedlings of summer corn

Technical field

The present invention relates to the production cultivation field of crops, specifically a kind of seedling raising and transplanting high-yield culture technique of summer corn.

Background technology

After northern area wheat harvest, flat planting Summer Corn Growing Period is short, light, heat deficiency, and wheat cover corn field of summer can not apply fertilizer to the subsoil, and seedling stage, fertility was not enough.At present people, in the production cultivation of summer corn, are the methods with traditional disposable thinning final singling of sowing, and its shortcoming is, two season the crop climate and other natural phenomena of a season tight slightly; Can not make full use of luminous energy; Yield poorly.

Summary of the invention

The present invention is for solving in the production cultivation of summer corn, and problem late, that yield poorly is gathered in the crops in the disposable thinning of sowing, final singling, invents a kind of summer corn seedling growing method of seedling raising and transplanting.

Technical scheme of the present invention is, a kind of seedling-cultivating method of summer corn comprises the links such as selection of land is built seedbed, standby nutritious bag, preparation Nutrition Soil and pack, begins sowing in good time, chosen seeds, sowing, seed treatment, seedling management management, and its special character comprises:

Build seedbed: selection of land gesture is high and dry, wind sheltering, irrigation and drainage on the sunny side conveniently, are done seedbed near the idle plot of planting site.Generally educate 7-10 square metre and can transplant 1 mu of land for growing field crops.

Standby nutritious bag: available paper bag, also available nutritive cube, approximately 9 centimetres with a high standard, 5 centimetres of garden diameters, every mu standby 5000.

Preparation Nutrition Soil: get 7 parts, the sandy loam that sieves, fully become thoroughly decomposed 3 parts, the ox, the sheep excrement that sieve fully mix, and add 0.25 kilogram, urea, 0.25 kilogram of diammonium phosphate, 0.25 kilogram of potassium sulfate by 1 cubic metre of Nutrition Soil simultaneously.Begin sowing in good time: before preceding crop is received the florescence, within 10-15 days, grow seedlings.

Seed selection, sowing and seedling management: select the hybridization breeding of the dressing that high-quality, high yield, ripe phase are moderate, during sowing 1 every bag, after planting water immediately, keep moistening, when seedling grows to 3-4 leaf, cultivate, while growing seedlings, rebasing with plastic film, Seedling bag is drawn close and ajusted one by one.

In time field planting: the whole ground of deep ploughing in time after wheat harvest, in conjunction with whole land, execute 4000 kilograms of the fertilizers that fully become thoroughly decomposed, 60 kilograms of superphosphate, 50 kilograms, carbonic hydroammonium, 18 kilograms of potassium sulfates.Behind whole good ground, do the little furrow of wide 1.5 meters, in order to field planting.

Technique effect of the present invention is, adopts technique scheme, can realize a kind ofly first growing seedlings and transplanting afterwards, can improve the seedling culture technology of the summer corn of output 30%.

Specific embodiment

Selection of land is built seedbed: select hidding and sunny side, near the plot in land for growing field crops, do seedbed, 10 square metres of areas.

Standby nutritious bag: 3000 of standby nutritive cubes, seedling raise period: June 5.

Preparation Nutrition Soil and pack: 50kg fine earth mixes and stirs the thin excrement of 50kg, separately adds k ₂so ₄composite fertilizer 5kg, uniform mixing, puts into nutritive cube.

Seed selection, sowing and seedling management: select the beautiful 86 maize seed 1.25kg of pellet of dressing, 1 every bag, after broadcasting, water immediately, and note dry wet degree, keep the skin wet in time, after the little wheat harvest of preceding crop, June 18 transplanted.

The extermination of disease and insect pest: prevent eliminating aphis seedling stage with 10% imidacloprid wettable powder 2000-2500 times of liquid spraying; With 5%, press down 1500-2000 times of liquid control mythimna separata of hooligan's missible oil; Use phoxim granulation agent control of maize snout moth's larva mid-term.
