Abstract

The invention relates to a high-yield rape planting method. The method is characterized by comprising steps as follows: land treatment is performed, firstly, the land is leveled, then wide-spaced ridges and shallow furrows are formed, and the soil humidity is kept in the range of 18%-50%; during sowing, seedling transplantation is performed, seedlings are transplanted about 12 days after emergence of the seedlings, a common fertilizer is applied in the growth period of the rape, and 8 kg of the fertilizer is applied to each mu of the land once a week during the early growth period of the rape. The method has the advantages as follows: the yield of the rape can be multiplied with the adoption of modes of frequent application of a small quantity of fertilizers each time and water-saving irrigation during growth of the rape.

Description

A kind of yield of Brassica napus L implantation methods

Technical field

The present invention relates to a kind of yield of Brassica napus L implantation methods.

Background technology

Current China generally adopts deep ploughing to sow at rapeseed cultivation, cause line space and strain spacing very tight, and generally deficiency is irrigated in plantation backward, therefore cause in growth of rape process and do not have enough spaces, rape growth is bad, the particle of the knot cangue of rape is few, thousand particles are heavy little, and therefore final output is not high, therefore urgently invents the new method of the plantation rape made new advances, to improve yield of rape, the problem that China arable land is not enough can be solved.

Summary of the invention

The object of the invention is to solve the problems referred to above existing in rapeseed cultivation management in prior art, a kind of yield of Brassica napus L implantation methods is provided.The present invention designs a kind of yield of Brassica napus L implantation methods, it is characterized in that: arrange soil, first levels land, and then arranges width ridge, shallow ridges landform, keeps the humidity of soil 18%---and 50%; Sowing adopts seedling raising and transplanting, waits after emerging 12 days and transplants, and within the growth of rape phase to fertilize, only adopts in two middle of the month at growth of rape initial stage and applies fertilizer weekly once, 8 kilograms every mu at every turn.The central authorities being planted in ridge of Brassica campestris L seedling, arrange in one, at a distance of 60 centimetres between often arranging, the centre position, soil between two row offer shallow ridges.The line-spacing of the Brassica campestris L seedling often between row is 40 centimetres.Advantage of the present invention adopts thin fertile duty to execute in growth of rape, and water-saving irrigation in process of growth, can ensure that yield of rape is doubled.

Embodiment

The present inventor has applied for two patents, 2011101749907, be a kind of irrigation method, 2013104519342 is a kind of factory farming implantation methods utilizing irrigation method above, and inventor is according to research, find each self-applying of root system of plant, through the practice of 3 years, substantially having grasped the rule of root system of plant in growth, be exactly plant absorption nutriment is shallow taking root, it absorbs moist fat gas, and dark Root Absorption moisture content.The realization of the present invention's above-mentioned basic law just.

During actual plantation, soil is carried out smooth to only possible level, arrange shallow ridges 30*15 centimetre wide, District of Shanghai generally before September 1 after carry out nursery, wait after emerging 12 days, transplant, the line-spacing of the plant of Brassica campestris L seedling 40 centimetres, the distance between row is 60 centimetres.It is to be noted that require will permeate when irrigating soil, keep soil moisture degree 18---between 50% (here the 50% dry mud referring to a not water content adds a water), the circulation of the high end, intermittent irrigation, after transplanting, realize thin fertile duty to execute, only adopt at the growth of rape initial stage and apply fertilizer weekly once, every mu of 8 kilograms of urea at every turn.The present invention, the interim fertilising of whole growth of rape sixties kilograms/every mu, has saved fertilizer greatly.

Because fertilizer when high more seedlings easily occurs damage by disease and insect, so will with industrialized standard setting Time and place, set the circulation of beneficial gas, fertilizer under executing early stage at soil table through the breeding of microorganism and excretion, to breathe out beneficial gas, ensure that the wetness of soil and the moisture discharged, cater to the air of extraneous room temperature, define three-dimensional synthesis rape highly dense strain crossings on different level effect, benefit gas air under branches and leaves is hovered, by shallow take root absorb, and can not run off, damage by disease and insect will be prevented in vegetative period, flexible Application can be carried out according to the geographic climate of locality in each department, can give stable high yields irrespective of drought or water logging, the output reaching rape seed is doubled.

In addition the rape owing to adopting method of the present invention to plant can grow tall, and answer this, also must note preventing rape from lodging in the later stage, can take the measure of some lodging-preventions, as carried out lodging-prevention with support bar or with coarse grid.To ensure the high yield of rape.

Claims

1. a yield of Brassica napus L implantation methods, is characterized in that: arrange soil, first levels land, and then arranges width ridge, shallow ridges landform, keeps the humidity of soil 18%---50%; Sowing adopts seedling raising and transplanting, waits transplanting in about 12 days of emerging, and within the growth of rape phase to fertilize, only adopts in two middle of the month at growth of rape initial stage and applies fertilizer weekly once, 8 kilograms every mu at every turn.

2. by a kind of yield of Brassica napus L implantation methods according to claim 1, it is characterized in that: the central authorities being planted in ridge of Brassica campestris L seedling, in row, at a distance of 60 centimetres between the rape row on adjacent ridge, the centre position, soil between two ridges offers shallow ridges.

3. by a kind of yield of Brassica napus L implantation methods according to claim 2, it is characterized in that: the line-spacing of the Brassica campestris L seedling between row is 40 centimetres.
