Description

Technical Field

[0001] The invention relates to the technical field of rice planting, and in particular to a herbal nutrient solution and a preparation method thereof and application thereof in seed cultivation. Background Art

[0002] Rice is a cereal crop of the genus Oryza, with Oryza sativa as the representative species. Rice is divided into indica rice and japonica rice, early rice and mid-late rice, glutinous rice and non-glutinous rice according to the type of rice grains. It is divided into conventional rice and hybrid rice according to the density of planting. The grains of rice are called rice grains, and the husks of rice grains are removed, which is called brown rice. The rice is obtained by grinding the bran layer of brown rice. Nearly half of the world's population relies on rice as their staple food. In addition to being edible, rice can also be used as industrial raw materials for brewing and making sugar, and rice husks and rice straw can be used as livestock feed. The main rice producing areas in China are mainly the Yangtze River Basin, the Pearl River Basin, and the Northeast. Rice is a direct cash crop and the staple food of Chinese residents. At present, the domestic rice planting area of ​​conventional rice is 245 million mu.

[0003] Conventional rice cultivation uses a large amount of chemical fertilizers and pesticides, which can cause residual damage, leading to soil compaction and imbalance of soil microbial systems. In addition, the frequent use of pesticides has caused diseases and pests to develop resistance, leading to an increase in the number and amount of pesticides used, increasing environmental pollution and ecological damage, thus forming a vicious cycle of pesticide abuse. At the same time, through the gradual enrichment of the food chain,

[0004] Finally it enters the human body and causes chronic poisoning. Summary of the invention
