Microbial fertilizer for promoting rice to absorb nutrients, and preparation method of microbial fertilizer

Abstract

The invention relates to microbial fertilizer for promoting rice to absorb nutrients, and a preparation method of the microbial fertilizer. The microbial fertilizer is prepared from the following mainraw materials: agrobacterium rhizogenes A4, R1205, R1000, R1601, R1022 and 15834. The agrobacterium rhizogenes has a function of promoting plants to root and grow and further promotes the plants to absorb the nutrients, thus having an important influence on plant growth and development; therefore, after being applied to rice seedlings in the period with 2-3 pieces of compound leaves, the microbial fertilizer, which is prepared from agrobacterium rhizogenes liquid with an OD value of 0.4-0.6, an organic matter composition and common soil, can stimulate the growth of rice root systems and increase the absorption area of roots, enhances the ability of the rice to absorb the nutrients, and mainly promotes the absorption of rice for N and P, thus promoting the growth of the rice, and solving the problems of low quality and low yield in rice production. The microbial fertilizer is beneficial to improvement of potential economic benefits of crops and is good for agricultural production.

Description

technical field [0001] The invention relates to a microbial fertilizer for promoting rice nutrient absorption and a preparation method thereof, belonging to the field of agricultural technology. Background technique [0002] Rice (Oryza sativa L.) is an annual grass plant with a height of about 1.2 meters, long and flat leaves, and panicles composed of many spikelets. The fruit is rice, which is called rice or rice after shelling. Rice can be divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice. In addition to being edible, rice can also be used as a raw material for wine making and sugar refining. Rice husk and rice straw also have many uses. Nitrogen deficiency is easy during growth. When rice is deficient in nitrogen, the leaf volume decreases, the leaves of the plant turn yellow from bottom to top, the rice plants are short, there are few tillers, and the leaves are erect. Timely topdressing of microbia...
