High-density rice planting method

Abstract

The invention discloses a high-density rice planting method. The method includes following steps: step 1, preparing a field: selecting a rice field good in ecological condition, free of pollution, convenient for irrigation and drainage, fertile in soil and free of residual pesticide toxicity and harmful substance; step 2, sufficiently applying base fertilizer which can improve soil, promote thickening of a soil mellow soil layer and retain fertilizer and water and is conducive to rice root system and tiller growth; step 3, selecting variety: selecting a high-quality variety excellent in quality, high in yielding ability and stress resistance and wide in application range. The method has the advantages that seeds are strictly disinfected, so that field disease source base number is lowered,primary infection of pathogenic bacteria is reduced, and crop disease are prevented; agricultural machinery is combined for sowing pest prevention, so that working efficiency is improved; rice seed planting density, rice yield and economic benefit are increased.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a high-density rice planting method. Background technique [0002] Rice is native to tropical Asia. After being widely planted in China, it gradually spread to all parts of the world. According to different methods, rice can be divided into indica rice and japonica rice, early rice and mid-late rice, glutinous rice and non-glutinous rice. Chinese scientist Yuan Longping’s research on hybrid rice He has made great contributions and is known as the "father of hybrid rice". The rice produced by rice is called rice or rice after the husk is removed. Nearly half of the world's population feeds on rice. There are various ways to eat rice. Rice, rice porridge, rice cakes, rice cakes, rice noodles, etc. In addition to being edible, rice can also be used to make wine, make sugar, and be used as industrial raw materials. Rice husks and rice straws also have many uses, but in the proc...

Rice, rice porridge, rice cakes, rice cakes, rice noodles, etc. In addition to being edible, rice can also be used to make wine, make sugar, and be used as industrial raw materials. Rice husks and rice straws also have many uses, but in the process of rice planting, the planting density is low , seriously affected the rice yield and reduced the economic benefits of growers
