Abstract

The invention provides a nutrient solution for rice in a cold region in a seedling stage. The nutrient solution is prepared from the following raw materials: bacillus subtilis, actinomycetes, enzyme microorganisms, lactic acid bacteria, bacillus megatherium and soybean meal fermentation liquor. The nutrient solution is sprayed for three times in the rice seedling stage, and the PH value of a seedbed is always kept between 4.5 and 5.5. Probiotic groups are formed around the developed seedling roots, so that infection of harmful germs is controlled, and diseases such as green and dead rice in the seedling stage of the rice are effectively prevented.

Description

technical field [0001] The invention relates to the field of rice planting, in particular to a cold region rice seedling stage nutrient solution and a preparation method thereof. Background technique [0002] In my country, the rice area north of 40 degrees north latitude is usually called the cold area rice cropping area. The growth characteristics of cold area rice are short growth days, less active accumulated temperature, slow heating in the early stage, short high temperature time in the middle stage, rapid cooling in the later stage, and more low temperature and chilling damage. . [0003] The main diseases at the seedling stage, such as blight, bacterial wilt and bakanae, occurred in the process of rice dry seedlings have brought serious losses to the majority of rice farmers. Very serious, seriously affecting rice production. [0004] In the prior art, the methods of preventing and controlling diseases such as bacterial wilt and bacterial wilt of cold-area rice are ...
