Cultivation method of ultra-rare planting rapeseed based on non-destructive planting technology of in-situ potting with medium-sized rice stubble

Abstract

The invention belongs to the technical field of rape cultivation, and in particular relates to an ultra-sparse rape cultivation method based on the in-situ pot-making non-destructive planting technology of medium rice stubble. The ultra-sparse rape cultivation method based on the in-situ non-destructive planting technology of medium rice stubble according to the present invention does not pursue simple high-yield, but makes full use of the middle rice stubble vacated earlier in the existing planting, and makes use of the "rape seedling stage". The reality of good temperature, light, and good water resources" gives full play to the advantages of individual yields, and creatively uses the "in-situ potting" method to plant rapeseed. The entire planting process does not require stubble removal, ditching, seedbeds, and furrow trimming. The "non-destructive colonization" of the planting process is realized. The whole process of making pots and sowing can be easily completed in less than 1 working day, saving a lot of labor, seed and fertilizer costs, and obtaining suitable yields with less workload, which has good economic value.

Description

technical field [0001] The invention belongs to the technical field of rapeseed cultivation, and in particular relates to a super-rare-planted rapeseed cultivation method based on the non-destructive planting technology of making pots in situ with medium-sized rice stubble. Background technique [0002] Brassica napus (B.napus, AACC, 2n=38) is an important oil crop widely planted in my country. , CC, 2n=18) were naturally crossed and formed by natural doubling. Brassica napus is divided into winter rape, semi-winter rape and spring rape according to vernalization requirements; among them, semi-winter rape is mainly distributed in the Yangtze River Basin of my country, and spring rape is mainly distributed in Northwest regions such as Gansu, Qinghai, Inner Mongolia and Tibet . The Yangtze River Basin is the main producing area of ​​rapeseed in my country, and it is also the largest oil crop in the country. In recent years, the planting area has stabilized at about 90 million ...

Problems solved by technology

Another example is the direct-seeding technology of flat fields studied by Luo Yin et al. (2016), the yield can reach 180kg / mu, but this method still requires ditching and whole furrows, and part of the stubble must be removed, otherwise the rice stubble will hinder ditching, so the reduced labor limited
