Problems solved by technology

[0002] At present, the method for cultivating rapeseed in the prior art generally adopts the method of sowing and transplanting to carry out rapeseed cultivation. In order to increase the yield of rapeseed, in the prior art, the production of rapeseed is generally improved from the idea of ​​improving rapeseed, according to this However, the method of cultivating rapeseed is still carried out according to the original cultivation method. Due to the backwardness of the cultivation method, the yield of rapeseed generally hovers around 200 jin per mu, so now Some Rapeseed Cultivation Methods Are Not Ideal

Embodiment Construction

[0006] Embodiment of the present invention: carry out sowing and transplanting of rapeseed according to the sowing and transplanting methods of existing cultivated rapeseed, its sowing date is selected on October 4th, and the transplanting period is selected on November 8th, and the transplanting density is controlled at row spacing 60cm, nest distance 27cm, the number of plants per mu is about 4115, when the rape grows to 9 leaf age or 12 leaf age or 15 leaf age or 18 leaf age, top the rapeseed, so that the topped rapeseed retains 9 leaves ~18 leaves; but it is best to top the rape when the rape is 12 leaves old, so that the topped rape can retain 12 leaves. When raising seedlings of rapeseed, it is best to adopt the method of nutrient balls to raise seedlings, and then adopt the technology of combining nutrient balls and the topping method of the present invention to achieve the effect of greatly increasing yield.

Abstract

A method for cultivating rape by removing its top to obtain high yield features than when the rape plant is growing to have 12 leaves, its top is removed to reserve the 12 leaves. It can increase its yield by 20% or more.

Description

Technical field: [0001] The invention relates to a high-yield cultivation method for topping rapeseed, which belongs to the technical field of rapeseed cultivation. Background technique: [0002] At present, the method for cultivating rapeseed in the prior art generally adopts the method of sowing and transplanting to carry out rapeseed cultivation. In order to increase the yield of rapeseed, in the prior art, the production of rapeseed is generally improved from the idea of ​​improving rapeseed, according to this However, the method of cultivating rapeseed is still carried out according to the original cultivation method. Due to the backwardness of the cultivation method, the yield of rapeseed generally hovers around 200 jin per mu, so now Some rape cultivation methods are not ideal. Invention content: [0003] The purpose of the present invention is to provide a high-yield cultivation method for topping rape which is simple and easy to operate and can significantly incr...
