Cultivation method for rape and cotton continuous cropping

Abstract

The invention discloses a cultivation method for rape and cotton continuous cropping, and belongs to the field of crop cultivation. The cultivation method of rape and cotton continuous cropping with both no-tillage, stubble direct seeding and no-uprooting cotton stalks is adopted, and the rape and the cotton are selected from early-maturing varieties; rapeseeds are directly spread between cotton stubble rows before the cotton is harvested, cotton stalks are free from uprooting after the cotton is harvested, the rape grows freely between the cotton rows, when the rape is harvested in summer, the cotton stalks are harvested, smashed and returned to field, and then the cotton is seeded directly in stubble in summer. According to the cultivation method for the rape and cotton continuous cropping, new varieties and new technologies are utilized, so that the symbiotic period of the rape and the cotton in the field is shortened, production in two seasons in a year and harvesting twice in a farmland are realized, thereby improving the annual benefits and increasing the multiple-cropping index; and the light simplified and mechanized operation is facilitated, the labor cost is reduced, andthe economic benefit is improved, and therefore the cultivation method is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to an oil cotton continuous cropping cultivation method. Background technique [0002] Oil-cotton continuous cropping is the main crop cultivation mode in the Yangtze River Basin. The growth period of the two crops is generally long in the field, and there are only 365 days in a year. The cotton is 200 days in the field, and the rapeseed is 200 days in the field. The growth time overlaps, and the symbiotic period is as long as 40-60 days. In order to solve the problem of using the same land to plant two crops in different seasons at the same time, the method of seedling cultivation and transplanting is generally adopted to alleviate such contradictions. Traditional continuous cropping of oil cotton It also adopts the method of raising seedlings and transplanting, but now the labor cost is rising and the labor intensity is high. In the season of rushing to plant and rush to harvest, t...

[0002] Oil-cotton continuous cropping is the main crop cultivation mode in the Yangtze River Basin. The growth period of the two crops is generally long in the field, and there are only 365 days in a year. The cotton is 200 days in the field, and the rapeseed is 200 days in the field. The growth time overlaps, and the symbiotic period is as long as 40-60 days. In order to solve the problem of using the same land to plant two crops in different seasons at the same time, the method of seedling cultivation and transplanting is generally adopted to alleviate such contradictions. Traditional continuous cropping of oil cotton It also adopts the method of raising seedlings and transplanting, but now the labor cost is rising and the labor intensity is high. In the season of rushing to plant and rush to harvest, the labor force is more tense, and the field housework cannot be completed in time, which will affect the income and benefits of farming.

[0003] This shows that above-mentioned existing oil cotton continuous cropping cultivation method obviously still has inconvenience and defective, and demands urgently further improving
