Abstract

The invention discloses a cultivation method for preventing rice blast. The cultivation method comprises the steps that seed soaking treatment is conducted using a seed-soaking solution, the seed-soaking solution contains 2%-10% of oxygen dissolution concentration and rice rhizosphere isolates; another type of rice rhizosphere isolates is applied to the soil of rice planting; in the jointing period, 10%-20% volume percentage of an ethanol solution is sprayed for the plants, the ethanol solution also contains: impatiens balsamina extraction, small fennel extraction, licorice extraction and pearl grass extraction; in the tiller period, another rice rhizosphere isolates solution of 1x103 to 1x105CFU / plant is sprayed to the plants; in the grouting period, a rice rhizosphere isolates solution of 1x104 to 1x106CFU / plant is sprayed to the plants; in the maturity period, another rice rhizosphere isolates solution of 1x105 to 1x107CFU / plant is sprayed to the plants. In the jointing, tillering, grouting and maturity periods, an aqueous solution is also irrigated to the plants, the aqueous solution contains ginger juice, artemisia argyi juice, chitin oligosaccharides, garlic juice, extracts of sindapsus aureus, clothianidin, coffee powder and tea leaves.

Description

technical field [0001] The invention relates to a cultivation method for preventing rice blast. Background technique [0002] Rice blast is the main disease of rice production in my country, threatening the food security of our country. Rice blast is one of the main diseases of rice caused by Magnaporthe Oryzae, which can occur all year round and can harm various parts of rice. Rice blast is a phytopathogenic fungus that causes severe diseases that attack rice and related plants. It causes economically significant crop losses each year, accounting for 40% of the estimated loss in crop yield. Each growing season, rice blast destroys enough rice to feed millions of people around the world. Rice is an important food crop in my country. Every year, a large area of ​​rice in my country is harmed by rice blast, and the annual loss of rice production is very large, resulting in huge economic losses. How to efficiently and safely prevent and treat rice blast is a major problem f...
