Rotation tillage planting method for totally returning double cropping straws of wheat and rice

Abstract

The invention belongs to the technical field of crop farming and cultivation and discloses a rotation tillage planting method for totally returning double cropping straws of wheat and rice. The rotation tillage planting method for totally returning double cropping straws of wheat and rice comprises: after harvesting wheat, totally crushing and returning the straws; after dry land regulation of a wheat field, filling the wheat field with water and pulping, and maintaining a 1-2 cm inter-field water layer; after weeding, mechanically transplanting rice seedlings; performing fertilizer and water management and pest control in a rice season; after rice is ripe, harvesting rice by a combine-harvester, and totally crushing and returning the straws; and after harvesting, performing tillage and airing and rotary tillage operations, and then sowing wheat. According to the rotation tillage planting method for totally returning double cropping straws of wheat and rice provided by the invention, on the premise of totally returning double cropping straws of wheat and rice, the soil structure and the soil quality are improved by changing a tillage mode of soil in the rice season, so that the planting and growth of a next crop of wheat are not affected. Moreover, in a key production link, mechanical operations are adopted, so that labor intensity and a production cost are lowered substantially, and meanwhile, total returning of the straws facilitates cultivating soil fertility so as to achieve carbon sink effect and reduce environmental pollution.

Description

technical field [0001] The invention relates to the technical field of crop farming and cultivation, in particular to a method for planting in rotation by returning full amount of wheat and rice double-ripe straws to the field. Background technique [0002] Rice is one of the main food crops in my country, with a planting area of ​​about 33 million hectares, accounting for 23% of the world's total rice area, and about 60% of China's population feeds on rice. Safety is of the utmost importance. The paddy and dry rotation areas are mainly distributed in the middle and lower reaches of the Yangtze River and parts of the hilly areas of the Jianghuai Plain, including five provinces including Jiangsu, Zhejiang, Anhui, Hubei, and Sichuan. They are important grain, wheat and oil production areas in my country. Accounting for 36.2% and 24.7% of the whole country, it plays a key role in ensuring national food security. Despite this, there are still phenomena such as the degradation of...

Problems solved by technology

Despite this, there are still phenomena such as the degradation of cultivated land quality, low resource utilization (mainly the by-products of agricultural production - straw), heavy fertilizers and heavy medicines, and the transfer of rural labor force structure, making modern agriculture gradually tend to scale The direction of agriculturalization and mechanization of farming is developing, which poses new challenges to the current farming system

In my country, there are about 700 million tons of straw every year. There is no doubt that straw returning to the field has the effect of fertilizing the soil. However, due to the improper method and method of straw returning to the field and the lack of supporting rotation technology and agricultural machinery, the actual production is still not enough. It shows the effect of increasing production and efficiency, which leads to the low enthusiasm for returning straw to the field in rural areas. Most of them use incineration and random dumping, which seriously wastes natural resources and brings serious environmental pollution.
