CN104365335A - Oilseed rape planting method - Google Patents

Abstract

The invention relates to a planting method, in particular to an oilseed rape planting method. A smooth, fertile, loosened and apricus seedbed which is supplied with water conveniently is selected, the seedbed is deeply ploughed by 25 cm to finely ground soil, a proper amount of fertilizer is applied to each mu of land by combination of soil preparation, sowing is carried out at the temperature of 21-22 DEG C, young seedlings are thinned out early after seedlings sprout in order, seedlings are reserved evenly, final singling of seedlings is carried out at the proper moment, top dressing is carried out between the second leaf period and the third leaf period, and paclobutrazol of 100 mg/kg is sprayed during the third leaf period to cultivate short strong seedlings. Oilseed rapes are planted according to the method, fertilizer losses are reduced, the use amount of chemical fertilizer is reduced, the fertilizer efficiency is improved, and the yield of oilseed rapes is remarkably improved through reasonable compact planting.

Description

A kind of rapeseed cultivation method

Technical field

The present invention relates to a kind of implantation methods, particularly relate to a kind of rapeseed cultivation method.

Background technology

Rape due to blade large, leaf area index is high, traditional specification is adopted to plant rape, agricultural machinery participates in field management and will cause the mechanical damages such as serious blade broken, affect the normal growth of rape, therefore, the field management of tradition Rape-seed production all adopts manual operation, labour has high input, cost is high, in recent years, along with urbanization process is accelerated, rural laborer goes down town and works, the problems such as Rape-seed production labour insufficient investment become the principal element of restriction Rape-seed production development, owing to lacking labour, often there is the phenomenon managing not in time even low level management in seedling management, cause Brassica campestris L seedling growing way weak, resist Drought in later stage, the natural calamity abilities such as freeze injury are weak, increase the weight of Weed infestation, club root, the occurrence and harm degree of the disease pest and weeds such as aphid, cause yielding poorly and unstable.

Summary of the invention

Order of the present invention is to provide a kind of rapeseed cultivation method.

The present invention is achieved by the following technical solutions:

A kind of rapeseed cultivation method, it comprises following aspect:

Select seedbed: ground, seedbed is smooth, fertile, loose, on the sunny side, water source facilitates, and front stubble did not plant rape and other crop in cruciferae for 2 ~ 3 years, and seedbed is 1:5 with the ratio of area of field;

Wholely: deep ploughing 25cm, makes soil in small, broken bits, in conjunction with whole every mu of organic fertilizer 2000 ~ 3000kg, superphosphate and each 20 ~ 30kg of ammonium carbonate, the wide 1.33m of seedbed furrow, furrow ridge 30cmo;

Sowing: sow when temperature is 21 ~ 22 DEG C, the amount of broadcasting should control at every 666.7m2, divides and broadcasts sowing for 2 ~ 3 times;

Seedbed management: early seedling thinning after neat seedling, evenly stays seedling, in good time final singling, and final singling stays 1 strain so that 7 ~ 8cm is square, and seedling 80,000 ~ 100,000 strain is stayed in every mu of seedbed;

Fertilizing management: topdress in 2 ~ 3 leaf phases, execute urea 5 ~ 7.5kg to water for every mu, five leaves control liquid manure later, execute urea 2.5kg for every mu and send and transfer fertilizer.Spray 1oomg/kg paclobutrazol in 3 leaf phases and cultivate short strong sprout.

By the rape that method of the present invention is planted, reduce the loss of fertilizer, decrease the consumption of chemical fertilizer, improve fertilizer efficiency, by rational dense planting, yield of rape is significantly improved.

Embodiment

Select seedbed: ground, seedbed is smooth, fertile, loose, on the sunny side, water source facilitates, and front stubble did not plant rape and other crop in cruciferae for 2 ~ 3 years, and seedbed is 1:5 with the ratio of area of field;

Wholely: deep ploughing 325cm, makes soil in small, broken bits, in conjunction with whole every mu of organic fertilizer 2000 ~ 3000kg, superphosphate and each 20 ~ 30kg of ammonium carbonate, the wide 1.33m of seedbed furrow, furrow ridge 30cmo;

Sowing: sow when temperature is 21 ~ 22 DEG C, the amount of broadcasting should control at every 666.7m2, divides and broadcasts sowing for 2 ~ 3 times;

Seedbed management: early seedling thinning after neat seedling, evenly stays seedling, in good time final singling, and final singling stays 1 strain so that 7 ~ 8cm is square, and seedling 80,000 ~ 100,000 strain is stayed in every mu of seedbed;

Fertilizing management: topdress in 2 ~ 3 leaf phases, execute urea 5 ~ 7.5kg to water for every mu, five leaves control liquid manure later, execute urea 2.5kg for every mu and send and transfer fertilizer.Spray 1oomg/kg paclobutrazol in 3 leaf phases and cultivate short strong sprout.
