Embodiment Construction

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] A method for whole-process mechanized cultivation of rice stubble and wheat, aimed at a rice-wheat rotation system, comprising:

[0043] 1. Straw returning to the field

[0044] Dry the field 5 to 7 days before rice harvest to reduce the soil moisture content in the field. Harvest rice with Kubota combine harvester, stubble height ≤ 25cm, crush rice straw while harvesting rice, and then use straw returning machine to crush and return the remaining straw in the field, requiring more than 85% of the straw length after crushing...

Abstract

The invention discloses a full-mechanical cultivation method of wheat following rice and aims at a rice-wheat rotation system. The method includes the steps of firstly, sunning the field before rice harvesting, and mechanically harvesting rice; secondly, preparing soil before sowing, wherein different soil preparing manners are adopted according to soil water content; thirdly, using different seedprocessing manners to process selected seeds according to different-disease-degree regions; fourthly, determining an appropriate sowing period according to weather, varieties and soil moisture content, using a sowing machine which integrates sowing, fertilizing and compressing to perform sowing in the appropriate sowing period, and applying base fertilizer during sowing, wherein sowing depth is regulated according to soil moisture content; fifthly, performing filed management; sixthly, harvesting from the late dough stage of the wheat to the full ripe stage of the wheat, and returning crushedwheat straw to the field. By the method, the systematic mechanical cultivation technology can be built, the planting quality of wheat following rice can be increased, and high yield can be achieved.

Description

technical field [0001] The invention relates to a method for cultivating rice stubble wheat, in particular to a method for whole-process mechanized cultivation of rice stubble wheat. Background technique [0002] Rice-wheat rotation is the main food crop production mode in the middle and lower reaches of the Yangtze River Plain. This mode is a multiple cropping mode in which wheat is sown after harvesting rice to achieve two crops a year. The rice-wheat rotation mode has a long planting history in this region, but the wheat season yield has always been at a low level, and the average yield per unit area is about 20% lower than the national average level, and about 50% lower than that in the Huang-Huai-Hai Plain wheat region. The reasons for the low wheat production in this region mainly include the following aspects: [0003] (1) Due to the long-term flooding of the previous crop of rice, the soil in the field is wet and sticky, and it is difficult to plow and prepare the l...
