Cultivation mothod for planting hybrid cole in ultra-low density

Abstract

An ultralow-density cultivation method for hybridized rape features that its planting density is greadly decreased to less than 500 plants per Mu without changing existing planting and manage ment modes. Its advantages are robust rape (5-9 cm for diameter and 2 m for height), and high yield of rapeseed (250 Kg / Mu).

Description

technical field [0001] The invention relates to a cultivation method of crops, in particular to an ultra-low density cultivation method of hybrid rapeseed. Background technique [0002] Rapeseed is one of the main raw materials of the oil industry, and it is a commercial crop widely planted all over the world, and it is the leading variety of oil crops in southern my country. [0003] In order to increase the yield of rapeseed, most of the attention has been paid to the improvement of rapeseed varieties for many years, and it has played a positive role. For example, the hybrid rapeseed Qinyou No. 2 and Qinyou No. 7, which are widely planted in my country, have a rapeseed yield of 100 per mu. kg, which has been greatly improved compared with traditional varieties. The plant heterosis of hybrid rapeseed is strong, and its field plant density is lower than that of traditional varieties. However, whether it is direct seeding or seedling transplanting at home...

Problems solved by technology

The technical problem to be solved by the present invention is: using the existing good hybrid varieties, without changing the planting and management mode, through the method of greatly reducing the planting density, not only the per unit yield of rapeseed can be greatly improved, but also the rapeseed planting The comprehensive economic benefits have also been significantly improved
