A nutrient-rich fertilizer and a preparation method thereof

Abstract

The invention discloses a nutrient-rich fertilizer and a preparation method thereof. The fertilizer is prepared from following raw materials in parts by weight: 40-50 of soybean straw, 20-25 of charcoal, 20-25 of peanut shell, 10-14 of urea, 11-13 of lignite, 12-14 of basalt powder, 11-14 of medical stone, 9-13 of peat soil, 10-12 of humus soil, 5-7 of amorpha fruticosa, 4-5 of flaccid knotweed herb, 10-12 of calcium superphosphate, 11-13 of potassium sulfate, and 9-11 of a soil modifier. The nutrient-rich fertilizer can meet the growth requirements of plants and can provide comprehensive and reasonable nutrition. The basalt powder can provide rich calcium, silicon, magnesium, sulfur, iron, copper, boron, zinc, cobalt, and other medium trace elements needed by the plants for the fertilizer. The peat soil can provide a large quantity of organic matters and humic acid and is capable of increasing the biological chemical activity of the soil, increasing the effective adsorption rate of the fertilizer, reducing soil hardening phenomena and reducing pollution of the fertilizer to the environment. The humic acid can absorb sunlight heat, thus increasing the soil temperature and preventing freeze injury and disordered seedlings. Accordingly, the fertilizer is capable of increasing the plant output largely and improving the quality of plants largely.

Description

technical field [0001] The invention relates to the field of fertilizer technology, in particular to a nutrient-rich fertilizer. Background technique [0002] my country is a big agricultural country, and it is also a big country that uses fertilizers. According to the statistics of my country's Ministry of Agriculture, the annual use of chemical fertilizers in my country accounts for 35% of the world's total. However, the nutrients of fertilizers in my country are mainly nitrogen, phosphorus, potassium and chlorine. Although the ratio of nitrogen, phosphorus and potassium can be adjusted according to the growth law of plants to better meet the different needs of plants, as the concentration of fertilizers increases, the ratio of raw materials The nutrient content is getting higher and higher, and high content will also affect the growth and reproduction of plants, which will cause plant yield reduction. And the content of trace elements may become lower. The high yield of...
