Problems solved by technology

However, because the soil environment is saline-alkali land or low-to-medium yield fields, the soil nutrients cannot meet the nutritional needs of alfalfa during the growth and development process, so the yield of alfalfa has been in a low state. With the increasing demand for high-quality pasture, how to improve the saline-alkali land and increase the yield of alfalfa is an urgent problem to be solved

Abstract

The invention discloses a special compound microbial fertilizer for alfalfa in saline-alkali soil and a preparation method thereof. The special compound microbial fertilizer is prepared from the following raw materials in parts by mass: a saline-alkali-tolerant phosphate-dissolving and potassium-dissolving rhizobium compound microbial agent, crop straws and waste branches, furfural residues, desulfurized gypsum, calcium superphosphate and fulvic acid. The preparation method comprises the following steps: crushing and drying the crop straws, waste branches and furfural residues, adding a fermentation and decomposition microbial inoculum, adjusting the moisture to be about 60%, adding desulfurized gypsum, and after aerobic solid-state fermentation is completed, adding fulvic acid, calcium superphosphate and the compound microbial agent to obtain the special compound microbial fertilizer for alfalfa in saline-alkali soil. The compound bacterial fertilizer improves the ecological environment of the saline-alkali soil, increases the yield of alfalfa, and realizes reasonable utilization of agricultural waste resources.

Description

technical field [0001] The invention belongs to the technical field of compound bacterial fertilizer, and in particular relates to a special compound microbial bacterial fertilizer for alfalfa in saline-alkali land and a preparation method thereof. Background technique [0002] Alfalfa (Medicagostativa L.) is a leguminous perennial herb with comprehensive nutrition, rich in crude protein, vitamins and mineral elements. It is recognized as the best grass in the world and known as the "king of grass". It can fix nitrogen in the air, increase soil organic matter content, and improve soil physical and chemical properties. Moreover, alfalfa can be planted in low-to-medium yield fields and saline-alkali soil environments with poor crop growth, without competing with grain and oil for land. When planting alfalfa, it can also improve saline-alkali soil, increase soil nitrogen nutrients, and improve the quality of the ecological environment. However, because the soil environment is ...
