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 slow-release fertilizer special for saline-alkali soil peanuts. The slow-release fertilizer special for saline-alkali soil peanuts comprises urea, ferrous sulfate, potassium sulphate, monopotassium phosphate, copper sulfate, single superphosphate, fermentation dung of beasts and birds, sulphur and sodium silicate. A manufacturing method includes the following steps that dung of beasts and birds such as the chickens are mixed in a proportion, undergoes fermentation, is dried, smashed and filled with the urea, the ferrous sulfate, the potassium sulphate, the monopotassium phosphate, the copper sulfate, the single superphosphate, the sulphur and the sodium silicate, smashed and evenly stirred. Particles are manufactured and dried to obtain the slow-release fertilizer. Disposable fertilization can continuously adjust the soil ph, damage to the saline ions is reduced and the nutritional requirement of peanuts in different growth periods can be met. The organic matter such as chicken dung is used for enriching the nutrition component of the soil. Organic dung of the chickens and the beasts and commonly-used inorganic fertilizers in production are used as raw materials and do not pollute the environment and the crops, wherein the organic dung of the chickens and the beasts is fermented thoroughly. Meanwhile, the formulation is reasonable, the nutrition is balanced, the use effect is better, the utilization rate of the fertilizer can be obviously improved and the yield and quality of the peanuts are improved.

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...
