Embodiment 1

[0020] A special fertilizer for peanuts in saline-alkali land,

[0021] The weight ratio of raw materials is 15 parts of urea, 5 parts of ferrous sulfate, 7 parts of potassium sulfate, 7 parts of potassium dihydrogen phosphate, 2 parts of copper sulfate, 20 parts of general calcium, 10 parts of livestock and poultry fermented manure, 3 parts of sulfur, silicic acid Sodium 2 parts.

[0022] The livestock and poultry fermented manure is obtained through the following steps:

[0023] Mix 2 parts of chicken manure, 3 parts of sheep manure, and 3 parts of cow manure according to the weight ratio to obtain mixed manure, crush the straw into small pieces of 5-8 cm, mix with the mixed manure at a weight ratio of 2:8, and make the heap width 1.5 m, the height of the pile is 0.8m, and a thermometer is inserted into the pile to detect the temperature; then 0.2% of the total mass is added to the starter, and the addition method is to add a quarter of the starter in the process of buildin...

Abstract

The invention relates to the technical field of crop fertilizers, in particular to a special slow-release fertilizer for peanuts in saline-alkali land, including urea, ferrous sulfate, potassium sulfate, potassium dihydrogen phosphate, copper sulfate, general calcium, livestock and poultry fermented manure, sulfur, and sodium silicate . Preparation method: mix the feces of chickens and other livestock and poultry in proportion to ferment, dry, pulverize, then add urea, ferrous sulfate, potassium sulfate, potassium dihydrogen phosphate, copper sulfate, general calcium, sulfur, sodium silicate to pulverize, Mix evenly, granulate, and dry. One-time fertilization can not only continuously adjust the soil pH, reduce the damage of salt ions, but also meet the nutritional needs of peanuts at different development stages; use organic matter such as chicken manure to enrich the nutrients of the soil; use inorganic fertilizers commonly used in production and fermented and decomposed peanuts Organic livestock and poultry feces are used as raw materials, which are non-polluting to the environment and crops. At the same time, the formula is reasonable, the nutrition is balanced, and the use effect is better. It can significantly improve the utilization rate of fertilizers and improve the yield and quality of peanuts.

Description

technical field [0001] The invention relates to the technical field of crop fertilizers, in particular to a special peanut slow-release fertilizer for saline-alkali soil improvement. Background technique [0002] Special slow-release fertilizer is an important means and way to improve crop yield and fertilizer utilization efficiency, and at the same time has the advantages of convenient application, strong pertinence, high yield, and good benefit. Due to the application of chemical fertilizers in my country's current agricultural production, soil salinization and secondary salinization are serious, and at the same time, there are a large number of saline-alkali lands in some coastal and inland areas, and soil salinization is likely to cause the solidification of nutrients in the soil. It is not easy to be used by crops, resulting in low fertilizer utilization rate, and the salinization of soil is not conducive to the growth and development of crops, affecting the yield of cro...
