Method for simply and efficiently producing seeds and cultivating hybrid rice

Abstract

The invention relates to the technical field of agriculture, and in particular relates to a method for simply and efficiently producing seeds and cultivating hybrid rice. A weeding composite is prepared from ethoxysulfuron and butachlor and has an obvious synergism and can be used for effectively preventing and removing gramineous weeds, nutgrass flatsedge and broad-leaved annual weeds. According to the method, the cultivation measures of accurately applying nutrients, completely removing the weeds in a land once and enabling the fertilizer to be long-lasting are carried out to achieve the purposes of being simple in cultivating, accurate in applying and increasing of the production benefits. With the adoption of the method, the labor intensity is greatly reduced, the labor input is decreased, and thus the economic benefit is increased; the method is simple, convenient and easy to be carried out, convenient to operate, easily accepted by farms, and suitable for a large-scale seed production base, and can be widely popularized and applied.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a light, simple and efficient hybrid rice seed production and cultivation method. Background technique [0002] Rice is not only the most important food crop in my country, but also one of the main food crops in the world. Nearly half of the world's population, including almost all of East and Southeast Asia, eat rice. Production is on every continent except Antarctica. In the late last century, the average annual rice output in the world was about 400 billion kilograms, and the planting area was about 145 million hectares. The sown area of ​​rice in my country accounts for 1 / 4 of the national grain crops, about 35 million hectares per year, while the output accounts for more than half. Regardless of planting area and output, rice ranks first among my country's food crops. [0003] Since the successful research of three-line hybrid rice in 1973, the application of hybri...

AI Technical Summary

Problems solved by technology

High yields can be achieved through precise fertilization and pesticide application, but the number of times and types of fertilizers and pesticides used are many, and farmers’ operations are complicated, labor intensive, and costly. Farmers are difficult to accept and popularize.

If various pesticides and / or fertilizers are used in combination, it is likely to produce antagonistic effects, which will affect the efficacy of pesticides and fertilizers, which is not conducive to hybrid rice seed production
