Full-valent organic compound fertilizer for alfalfa and preparation method thereof

Abstract

The invention discloses full-valent organic compound fertilizer for alfalfa and a preparation method thereof. The fertilizer is prepared from the following raw materials in parts by weight: 50 parts of wheat straw, 40 to 55 parts of cow dung, 0.01 part of trace element, 1.0 to 1.5 parts of bacillus, 2.0 to 2.5 parts of lactobacillus, 2.0 to 2.5 parts of saccharomycetes, 0.5 to 1.0 part of cellulase and 1.0 to 1.5 parts of hemicellulase. The trace element is prepared from the following raw materials in parts by weight: 3 to 4 parts of ferrous sulfate, 1 to 2 parts of zinc sulfate, 2 to 3 partsof ammonium molybdate and 1 to 4 parts of boric acid. The full-valent organic compound fertilizer for alfalfa disclosed by the invention has the following advantages that firstly, nutrition is more suitable, and for a soil condition in a Henan area, an appropriate proportion of the trace element is added, and the composition of the nutrition is more suitable for enabling the alfalfa to be grown inthe Henan area; secondly, fermentation is carried out more completely, through ball milling and enzymolysis, plant cell wall components of a mixed material are destroyed, and full and uniform fermentation of the straw and dung is facilitated; and thirdly, an effect is better. Compared with other organic fertilizer, the fertilizer prepared by adopting the preparation method disclosed by the invention has the advantages that the yield of alfalfa green hays can be improved more obviously, and a basic application amount is larger and an application effect is better.

Description

technical field [0001] The invention relates to an alfalfa full-priced organic compound fertilizer and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] At present, the world is facing serious problems of population increase and environmental degradation, and the extensive use of inorganic fertilizers in agricultural production has also made environmental degradation more serious. The deficiencies of inorganic fertilizers mainly include: destroying the soil, resulting in a decrease in soil organic matter content, imbalance of various nutrient ratios, acidification and compaction of the soil, serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in water retention and fertilizer retention of the soil. , poor air permeability, it is difficult to meet the actual growth needs of crops; the dependence of crops on chemical fertilizers and pesticides is gradually increasing, ...

Problems solved by technology

The deficiencies of inorganic fertilizers mainly include: destroying the soil, resulting in a decrease in soil organic matter content, imbalance of various nutrient ratios, acidification and compaction of the soil, serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in water retention and fertilizer retention of the soil. , poor air permeability, it is difficult to meet the actual growth needs of crops; the dependence of crops on chemical fertilizers and pesticides is gradually increasing, and the amount of use must be increased year by year, otherwise, the growth of crops will be slow, and the pests and diseases will be serious, resulting in reduced production; the agricultural ecological environment will deteriorate. , the actual utilization rate is only 30% on average, and most of them flow into rivers and lakes with farmland drainage or remain in the soil, plants and crops, which not only brings environmental pollution but also endangers human safety and health. These have become obstacles to the sustainable development of agriculture.

In response to this situation, many experts at home and abroad have conducted research on organic fertilizers, trying to make pure organic fertilizers directly replace inorganic fertilizers, but the current problem is that the quality of organic fertilizer products varies, and some directly use poultry manure or plant stalks. Fermentation, as an organic fertilizer, is not only difficult to meet the nutritional needs of plants, but also may remain toxins produced by improper fermentation, making it difficult to achieve good results

At present, the irrational allocation of fertilizer nutrients when planting alfalfa results in only a small part of nutrients being absorbed and utilized by alfalfa, and the yield of alfalfa is low

Moreover, the extensive use of inorganic fertilizers has also affected the soil environment and alfalfa production.
