Abstract

The invention provides a dual-purpose three-harvest quality-improving and efficiency-improving cultivation method for rice. The dual-purpose three-harvest quality-improving and efficiency-improving cultivation method for the rice comprises the following steps of variety selection, sowing, transplanting, first-season forage grass fertilization, first-season forage grass moisture management, first-season forage grass mowing, second-season ratooning rice fertilization, second-season ratooning rice moisture management, second-season ratooning rice harvesting, third-season forage grass fertilization, third-season forage grass moisture management and third-season forage grass mowing. According to the dual-purpose three-harvest quality-improving and efficiency-improving cultivation method for the rice, the problems of high edible rice yield and poor rice quality caused by high temperature stress in summer and high rice forage grass yield and poor rice quality of rice in the middle and lower reaches of Yangtze River in China can be effectively solved, and the problems of low utilization rate of temperature and light resources in rice planting and tension supply of high-quality animal feed in regions can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a dual-purpose, three-harvest, quality-improving and efficiency-enhancing cultivation method for rice. Background technique [0002] Rice is the main food crop in my country. With the development of the economy and the improvement of people's living standards, the consumption demand for rice has changed from "subsistence" to "nutrition", and the demand for high-quality rice is increasing year by year. In addition, milk, The proportion of animal food consumption such as meat and eggs is also on the rise. It is particularly important to ensure the effective supply of high-quality forage grass, especially in Southwest my country. There are about 130 million mu of winter paddy fields in southern my country's rice fields, and the general land is idle for 5-7 months in winter, resulting in a huge waste of temperature, light and precipitation resources in autumn and winter. On the...
