Effects of Microbial Fertilizer on Forage Growth and Soil Chemical Properties

The purpose of this study is to explore the effect of microbial fertilizer on pasture improvement. The natural grassland of Leymus chinensis grassland was selected as a test plot in a base, and each kind of plot was treated with different kinds of microbial fertilizer. Through the analysis of plant growth status, community biological characteristics and soil physical and chemical properties, the research of this paper is expanded and discussed in depth, which provides new methods and technical support for grassland improvement. The results showed that the community density of Leymus chinensis grassland was increased by 64.90% under the treatment of molasses. The output of Leymus chinensis was increased by 5. 41g/ml, and the biomass of Leymus chinensis was increased by 296.47%. Molasses fermentation is a kind of microbial fertilizer that can improve pasture production. In addition, under humic acid treatment, the yield and community yield of Leymus chinensis was decreased by 2.03g/m and 19. 61g/m, respectively. Humic acid can reduce grassland productivity, and it is not suitable for grassland protection and improvement. At the same time, alginic acid is not conducive to the growth of Leymus chinensis. After comprehensive consideration, alginic acid on the improvement of grass is not a good scheme. At last, three kinds of fertilizer mixed fertilizer in Leymus chinensis grassland community yield was increased by 6.01g/ml, and the yield of Leymus chinensis was increased by 27.54g/m. Based on above findings, we conclude that the mixed fertilizers can increase grassland productivity.
