Special organic and inorganic composite biological medicinal fertilizer for potatoes and preparation method thereof

Abstract

The invention discloses a special organic and inorganic composite biological medicinal fertilizer for potatoes. The medicinal fertilizer comprises the following raw materials in parts by weight: 30-50 parts of potato vines, 20-30 parts of livestock manure, 30-40 parts of spent mushroom compost, 8-12 parts of mycelia, 18-22 parts of distilled grains, 8-10 parts of bone meal, 10-12 parts of sodium humate, 10-12 parts of chicken feather, 7-10 parts of borax, 0.07-0.1 part of sodium molybdate, 0.8-1.3 parts of ferrous sulfate, 0.8-1.2 parts of potassium chloride, 4-6 parts of magnesium sulfate and 0.8-1.6 parts of microbial fermented matters. The invention also discloses a preparation method of the special organic and inorganic composite biological medicinal fertilizer for potatoes. Compared with the prior art, the medicinal fertilizer has the advantages that the medicinal fertilizer can protect the ecological environment and the farmland soil, is easily absorbed by crops, has obvious yield increase benefit, integrates double functions of fertilization and sterilization, is low in cost and is environment-friendly and pollution-free.

Description

technical field [0001] The invention relates to the field of fertilizers for agricultural production, in particular to an organic-inorganic compound biomedical fertilizer for potatoes and a preparation method thereof. Background technique [0002] The application of chemical fertilizers has played a key role in increasing agricultural incomes for many years. However, due to the long-term application of chemical fertilizers, insufficient supply of organic fertilizers, and imbalances in the proportion of various nutrients, the ecological environment of farmland, soil physical and chemical properties, and soil biota have been damaged to varying degrees, and the quality of agricultural products has been affected to a certain extent. Therefore, chemical fertilizer pollution has become a major public hazard in the world today. The current status of soil resources in my country urgently needs to supplement soil organic matter through artificial measures to ensure the level of agric...

Problems solved by technology

[0005] my country is a large agricultural production country. With the high utilization of fertilizers, the requirements for fertilizers are constantly increasing. At present, a large amount of inorganic fertilizers are used, which seriously leads to the increase of harmful substances in crops, poor quality, and incomplete nutrition. Secondly, the soil is easy to Hardening, poor drought resistance, and poor water retention performance, which seriously affects the normal growth of crops and poor economic benefits
