Embodiment Construction

[0026] The technical solution provided by the present invention will be described in more detail below, the technology obtained by replacing any technical means provided by the present invention or combining any two or more technical means or technical features provided by the present invention with each other All schemes should be within the protection scope of the present invention.

[0027] One embodiment of the present invention provides a microbial fertilizer suitable for saline-alkali land. The composite microbial bacteria are planted on the salt-tolerant medium at a volume ratio of 3% to 5% for solid fermentation until the concentration of microorganisms reaches 3.5 billion strains / g. That is to obtain microbial fertilizers suitable for saline-alkali land;

[0028] The components of the salt-tolerant medium include: corn cob powder, peat soil, soybean meal, light calcium carbonate, trehalose and sodium alginate; the weight ratio of each component is:

[0029] Corncob f...

Abstract

The invention discloses a microbial fertilizer suitable for saline-alkali soil, wherein composite microbial bacteria are inoculated into a salt-tolerant culture medium according to a volume ratio of 3-5%, and solid fermentation is performed until the concentration of microorganisms reaches 3.5 billion strain/g so as to obtain the microbial fertilizer suitable for saline-alkali soil, wherein the components of the salt-tolerant culture medium comprise corn cob powder, peat soil, bean meal, light calcium carbonate, trehalose and sodium alginate. According to the present invention, with the microbial fertilizer suitable for saline-alkali soil, the problems of rare fertilizers for saline-alkali soil, poor fertilizer efficiency and the like in the prior art can be solved, and the nutrients of saline-alkali soil can be increased, such that the saline-alkali soil can be suitable for growing ordinary crops in a short time.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a microbial fertilizer suitable for saline-alkali land. Background technique [0002] Saline-alkali land is a plot with high saline-alkali content in the soil, which is not conducive to the growth of plants. Saline-alkali land is mostly formed by the redistribution of various soluble salts in the horizontal and vertical directions on the ground, so that the salt gradually accumulates on the soil surface in the salt-gathering area. [0003] At present, the improvement of saline-alkali land in my country is generally divided into the following steps. First, salt discharge, salt washing, and reduction of soil salinity content; second, planting saline-alkali-tolerant plants and fertilizing the soil; finally, planting general crops. But the fertilizer that is applicable to saline-alkali land in the prior art is very scarce, and fertilizer efficiency is not good. Contents of the invention...
