Abstract

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. The seedling strengthening agent comprises the following raw materials in parts by weight: 5-20 parts of biological bacteria agent, 5-40 parts of distiller's grains, 10-30 parts of urea, 2-10 parts of potassium magnesium sulfate, 6-15 parts of superphosphate, 0.1-1 part of paclobutrazol, 0.1-1 part of naphthaleneacetic acid. The strain of the biological agent is Streptomyces albus, and the preservation number is CGMCC No.15117. The biological seedling strengthening agent of the present invention is safer to use and does not cause phytotoxicity. The low temperature resistance ability of rice can be enhanced, and the normal growth of rice can be prevented from being affected by low temperature. Turn distiller's grains from waste into treasure, use its own acidity to regulate the soil, and secondly use the medium and trace elements contained in it to provide nutrition for rice.

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 ...
