Abstract

The invention provides a rice field greenhouse gas emission reduction method based on straw returning, and the method comprises the steps: setting a first period rice planting mode based on a preset first period planting guidance information set, and planting rice according to the first period rice planting mode; autumn rotary tillage in the first period planting guidance information set is changed into autumn ploughing, a second period planting guidance information set is obtained, a second period rice planting mode is set based on the preset second period planting guidance information set, and rice is planted according to the second period rice planting mode. Due to the fact that rice planting is accurately and efficiently guided through various parameters set in the first period planting guidance information set and the second period planting guidance information set, the problem that rice straw returning to the field is difficult is solved, the rice straw is returned to the field completely, the soil fertility level of the rice field can be improved, and the rice planting quality is improved. The rice yield is high, and the greenhouse gas emission of the rice field can be remarkably reduced.

Description

technical field [0001] The present application relates to the technical field of agricultural production, and in particular, to a method for reducing greenhouse gas emissions in rice fields based on straw returning. Background technique [0002] Rice is the largest food crop in China. Among them, the production of rice in cold regions plays an important strategic role in ensuring national food security. [0003] However, in the process of rice cultivation in cold regions in my country, there are always problems such as difficulty in returning straw to the field and high greenhouse gas emissions. [0004] Among them, the problem of high greenhouse gas emissions is not only related to my country's international commitment to carbon peaking in 2030 and carbon neutrality in 2060, but it will actually lead to an increase in the average temperature of the earth, which will lead to global climate anomalies, and may even lead to glaciers in the Arctic and Antarctic. The occurrence ...
