Abstract

The invention discloses a biological seedling strengthening agent capable of enhancing rice stress resistance and a preparation method of the seedling strengthening agent, and belongs to the technicalfield of agricultural production. The seedling strengthening agent comprises, by weight, 5-20 parts of biological bacterium agents, 5-40 parts of distillers' grains, 10-30 parts of urea, 2-10 parts of potassium magnesium sulfate, 6-15 parts of calcium superphosphate, 0.1-1 part of paclobutrazol and 0.1-1 part of naphthylacetic acid. Biological bacterium agent strains are streptomyces albus, and the collection number is CGMCC No.15117. The biological seedling strengthening agent is safer to use and cannot generate chemical injury. Low-temperature resistance of rice can be enhanced, normal growth of the rice cannot be affected by low temperature, the distillers' grains are changed into wealth, soil is adjusted by acidity of the biological seedling strengthening agent, and nutrition is provided for the rice by the aid of medium trace elements in the biological seedling strengthening agent.

Description

technical field [0001] The invention discloses a biological seedling-strengthening agent capable of enhancing stress resistance of rice, and also discloses a preparation method of the seedling-strengthening agent. It belongs to the field of agricultural production technology. Background technique [0002] Rice is a traditional crop in my country, and it is also the main variety of food production in my country. The growth of rice in the seedbed directly affects its growth and quality and yield in the later stage. Rice is an acid-loving crop, and the suitable pH value is 4.5-5.5. The acidic environment can effectively promote the development of plants in the growth stage of seedlings, promote root system development and protect seedlings. There are various pathogenic bacteria in the rice seedling soil, which can easily induce rice blight, bacterial wilt and other diseases. Seedling strengthening agent is generally used in the initial stage of rice growth. The current rice ...
