Oilseed rape pod layer high-low staggered layer cultivation method

Abstract

The invention provides a high-low staggered cultivation method for pods of oilseed rapes. Short oilseed rapes and high oilseed rapes are uniformly sown on the same field; the plant number of the high-stalk rape accounts for 5%-20% of the plant number of the short-stalk rape; in the mature period, the plant height of the short-stem oilseed rape is not higher than 1.2 m, and the plant height of the high-stem oilseed rape is not lower than 1.5 m; the growth heights of all siliques of the high-stalk oilseed rape are higher than those of all siliques of the short-stalk oilseed rape. According to the method, by selecting the plant height difference of the high-stalk oilseed rape and the short-stalk oilseed rape in the mature period, the growth height of all siliques of the high-stalk oilseed rape is higher than that of all siliques of the short-stalk oilseed rape, the upper-layer space of the oilseed rape planting land is fully utilized, and the yield of the short-stalk oilseed rape is increased on the premise that the per unit yield of the short-stalk oilseed rape is basically not affected. The yield per unit of the high-stalk rape becomes the yield which is directly increased in unit area, so that the yield per unit of the rape is quickly increased.

Description

technical field [0001] The invention relates to the technical field of rapeseed cultivation, in particular to a method for cultivating rapeseed silique layers with high and low staggered layers. Background technique [0002] The annual production of edible vegetable oil in my country is about 10 million tons, while the annual output of rapeseed oil reaches 5-5.5 million tons, accounting for more than 50%. However, the self-sufficiency rate of edible oil in my country is less than 40%, which is far lower than the 95% self-sufficiency rate of grain. Therefore, it is of great practical significance to vigorously develop the rapeseed industry to increase the output of rapeseed and ensure the safety of edible oil in our country. There are two main ways to increase the yield of rapeseed: one is to breed high-yielding varieties of rapeseed to increase the yield per unit area of ​​rapeseed, and to increase the total output; the other is to directly expand the planting area of ​​rap...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a rapeseed silique layer high and low staggered layer cultivation method, which is used to solve the problem that the existing rapeseed cultivation method is to plant the same rape variety on the same field, so that the siliques all grow in the space of the same height range , failed to make full use of the upper space above the rapeseed planting ground, which resulted in the problem that the production of rapeseed was difficult to increase
