Problems solved by technology

Due to the influence of soil fertility and grazing culture in Inner Mongolia, the use of fertilizers is not paid attention to in production. In order to solve such fertilization problems, 102515950A discloses a kind of fertilizer for medium and low-yield alfalfa fields. The fertilizer uses nitrogen, phosphorus, and potassium fertilizers and organic matter as raw materials, which significantly increased the yield and quality of alfalfa in low- and medium-yield fields. However, the content of trace elements in sandy soil is low, and only adding macronutrients and organic matter to the soil is not enough to supplement the needs of alfalfa. trace element nutrition
According to research, it is found that the lack of boron will affect the growth of new tissue, limit the elongation of the stem, and the molybdenum element participates in the nitrogen fixation of rhizobia in the alfalfa plant. Therefore, for the above problems, the present invention proposes a special organic compound fertilizer for alfalfa

Abstract

The invention discloses a special organic composite fertilizer for alfalfa, and a preparation method for the special organic composite fertilizer. The preparation method comprises the following steps: by taking edible mushroom dregs and chicken manure as organic raw materials, adding rhizobium and an arbuscular mycorrhiza fungicide, and further mixing an organic composite fertilizer which takes mineral fertilizers as components. As rhizobia and arbuscular mycorrhiza are added into the fertilizer, the nitrogen fixing capacity of alfalfa plants is improved, and the absorption of alfalfa on phosphorus is improved. By adopting the special organic composite fertilizer, the soil structure can be improved, the water retention and fertilizer retention property is improved, and rich mineral substances and trace elements are provided for alfalfa to grow, the quality of alfalfa is remarkably improved, and the yield of alfalfa is increased, that is, the yield is increased by 50% or more.

Description

technical field [0001] The invention belongs to the research field of fertilizers and preparation methods thereof, and in particular relates to a compound fertilizer whose main raw materials are biological bacteria agents, edible fungus residues and chicken manure, and a preparation method thereof. Background technique [0002] Alfalfa (Medicago satica L.) is the leguminous forage with the widest distribution, the longest cultivation history and the highest economic value in my country, and is known as the "king of forage". Alfalfa plays an important role in promoting the development of grain-saving animal husbandry, improving the yield level of milk per unit area, and ensuring the quality of milk. [0003] According to preliminary calculations, each ton of alfalfa hay contains 6kg of phosphorus (P2O5), 26kg of potassium (K2O), calcium, magnesium, sulfur and other trace elements. Compared with other crops, alfalfa has higher nutritional requirements, and the nutritional sta...
