Slow-release fertilizer based on traditional Chinese medicine additives and preparation technology

Abstract

The invention relates to a slow-release fertilizer based on traditional Chinese medicine additives and a preparation technology. The slow-release fertilizer is prepared from the following components in parts by weight: 3 to 5 parts of traditional Chinese medicine additives, 20 to 30 parts of animal bone protein, 5 to 8 parts of organic humic acid, 10 to 15 parts of multi-element slow-release fertilizer, 10 to 15 parts of plant mixture, 5 to 10 parts of crosslinking agent, and 10 to 20 parts of water. The preparation technology comprises the following steps of after the traditional Chinese medicine additives, the plant mixture, the animal bone protein, the crosslinking agent and the slow-release additives are prepared, preparing the raw materials in parts by weight for further use; uniformly mixing the raw materials, so as to obtain fertilizer particles which can be balled by hands and be dispersed after falling onto ground; composting the fertilizer particles, spreading and airing after composting is finished, granulating by a granulating technology, and packaging, so as to obtain the finished product of the slow-release fertilizer. The prepared slow-release fertilizer has the advantages that the period of delaying the release of nutritional elements is long, the nutritional elements can be continuously supplied, and the traditional Chinese medicine additives can provide rich nutritional matters and regulate the acid and alkaline balance of the soil.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine agriculture, and in particular relates to a slow-release fertilizer based on traditional Chinese medicine additives and a preparation process. Background technique [0002] Fertilizer refers to a class of substances that provide one or more essential nutrient elements for plants, improve soil properties, and increase soil fertility levels. It is one of the material bases of agricultural production. In the existing technology, in order to meet the needs of the development of agricultural modernization, in addition to continuing to increase production, chemical fertilizer production is developing towards high-efficiency compounding, combined with fertilization mechanization, fertilizer transportation pipelines, and water and fertilizer sprinkler irrigation instrumentation. Liquid ammonia, ammonium polyphosphate, potassium polyphosphate, etc. have become the main types of chemical fertiliz...

Problems solved by technology

[0003] In the existing technology, chemical fertilizers can provide the nutrients needed for the growth of crops and plants. It has sufficient nutrients and quick results and has become the first choice of fertilizers for farmers. However, after years of practice, the disadvantages of chemical fertilizers have gradually been exposed. In the soil where more chemical fertilizers are applied, the content of inorganic matter soars, the organic matter is weakened, the trace elements are unbalanced, and crop diseases and insect pests are becoming more and more serious. The crops grown in this soil environment are not conducive to human health.
