CN101946611A - Seedling culturing and transplanting method for summer corn - Google Patents

Abstract

The invention discloses a seedling culturing and transplanting method for summer corn. The method is characterized by comprising the following steps of: selecting a lee plot facing the sun and closing to a field as a seedling bed, wherein generally 7 to 10 square meters of cultured seedlings can be transplanted to the 1mu field; preparing 5,000 paper bags or nutrition bowls with heights of about 9 centimeters and circle diameters of about 5 centimeters for later use every mu; adding 50kg of fine dung into 50kg of fine soil, adding 5kg of k2so4 compound fertilizer into the mixture, stirring the mixture uniformly and filling the mixture into the bags; culturing seedlings in 10 to 15 days before the florescence of a previous crop; and selecting high-quality and high-yield coated hybrid seeds with proper ripening stage, sowing one seed in each bag during sowing, immediately watering the seed after sowing, meanwhile paying attention to the soil dryness of the nutrition bags and supplementing water in time, keeping the soil moist, and planting the seedlings when the seedlings are grown with 3 to 4 leaves, wherein during seedling culturing, the seedling culturing bags are backed by using a plastic film and closed and placed regularly one by one. By adopting the technical scheme, a summer corn seedling culturing technique capable of culturing seedlings and then transplanting the seedlings and improving the yield by 30 percent can be realized.

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 the northern area wheat harvest flat planting summer corn vegetative period short, light, heat is not enough, wheat cover corn field of summer can not apply fertilizer to the subsoil, seedling stage the fertility deficiency.At present people are the methods with traditional disposable thinning final singling of sowing in the production cultivation of summer corn, 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 in the production cultivation that solves 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, comprise that choosing ground is built the seedbed, is equipped with nutritious bag, preparation nutrition soil and pack, begin sowing in good time, choose seeds, links such as sowing, seed treatment, seedling management management, its special character comprises:

Build the seedbed: select physical features high and dry, wind sheltering, irrigation and drainage are on the sunny side conveniently done the 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.

Be equipped with nutritious bag: available paper bag, also available nutritive cube, about 9 centimetres with a high standard, about 5 centimetres of garden diameter, every mu standby 5000.

Preparation nutrition soil: get 7 parts in the sandy loam that sieves, ox, the sheep excrement that sieves that fully become thoroughly decomposed fully mixes for 3 parts, adds 0.25 kilogram in urea by 1 cubic metre of nutrition soil simultaneously, 0.25 kilogram of diammonium phosphate, 0.25 kilogram of potassium sulphate.Begin sowing in good time: before preceding crop is received the florescence, grew seedlings in 10-15 days.

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

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

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

Specific embodiment

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

Be equipped with nutritious bag: be equipped with 3000 of nutritive cubes, seedling raise period: June 5.

Preparation nutrition soil and pack: the 50kg fine earth mixes and stirs the thin excrement of 50kg, and other adds k2so4 composite fertilizer 5kg, and nutritive cube is put in uniform mixing.

Seed selection, sowing and seedling management: select the red beautiful 86 corn kind 1.25kg of dressing for use, 1 every bag, water immediately after broadcasting, and note doing wet degree, in time keep the skin wet, the preceding crop wheat is received the back and was transplanted June 18.

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