Embodiment 1

[0026] The decomposed stalks are dried in the air, and the water content is reduced to below 15%, and then pulverized, and the particle size is ≤3mm. According to the weight ratio, take 400kg of straw, 15kg of lime nitrogen powder, 8kg of diammonium phosphate powder, 6kg of potassium sulfate powder, 0.5kg of ammonium molybdate powder, 0.2kg of borax powder, 0.5kg of copper sulfate powder, 0.5kg of zinc powder, 0.5kg of magnesium sulfate powder, 0.5kg of manganese sulfate powder, 0.3kg of ferrous sulfate powder and other components are uniformly mixed, and put into the mold according to the weight of each piece of fertilizer 40 grams. The briquetting machine is extruded to form a cylindrical block fertilizer, with a size of 5 cm in diameter and a height of 3 cm. According to the peanut variety, the number of plants planted in previous years, the spacing between plants, the row spacing and the yield, calculate the amount of special organic block fertilizer for peanuts per unit a...

Embodiment 2

[0028] The decomposed straw and peat are mixed in the air, and the water content is reduced to below 15%, and then crushed, and the particle size is ≤3mm. According to the weight ratio, take 450kg of straw, 12kg of lime nitrogen powder, 6kg of diammonium phosphate powder, 5kg of potassium sulfate powder, 0.5kg of ammonium molybdate powder, 0.2kg of borax powder, 0.5kg of copper sulfate powder, 0.5kg of zinc powder, 0.5kg of magnesium sulfate powder, 0.5kg of manganese sulfate powder, 0.3kg of ferrous sulfate powder and other components are uniformly mixed, and put into the mold according to the weight of each piece of fertilizer 30 grams. The briquetting machine is extruded to make a cuboid block fertilizer, the size of which is 3 cm in diameter and 2 cm high. According to the peanut variety, the number of plants planted in previous years, the spacing between plants, the row spacing and the yield, calculate the amount of special organic block fertilizer for peanuts per unit ar...

Embodiment 3

[0030] The decomposed straw and chicken manure are mixed in the air, and the water content is reduced to below 15%, and then crushed, and the particle size is ≤3mm. According to weight ratio, take straw 350kg, and lime nitrogen powder 18kg, diammonium phosphate powder 10kg, potassium sulfate powder 7kg, ammonium molybdate powder 0.5kg, borax powder 0.2kg, copper sulfate powder 0.5kg, sulfuric acid 0.5kg of zinc powder, 0.5kg of magnesium sulfate powder, 0.5kg of manganese sulfate powder, 0.3kg of ferrous sulfate powder and other components are uniformly mixed, and then put into the mold according to the weight of each piece of fertilizer 50 grams. The briquetting machine is extruded to form a cylinder-shaped block fertilizer with a size of 3 cm in diameter and 4 cm in height. According to the peanut variety, the number of plants planted in previous years, the spacing between plants, the row spacing and the yield, calculate the amount of special organic block fertilizer for pea...

Abstract

The invention relates to a production method and large-scale application of special organic block-type fertilizer for peanuts. Organic matters such as straws are used as a nutrient carrier to be proportioned with nutrients for peanut to be prepared into solid fertilizer by virtue of strong pressing way, when in application, the fertilizer is arranged in a depth of 20cm in a soil layer, then the fertilizer is covered with soil to plant the peanuts, and a precise quantitative fertilizer application way of one block of fertilizer for one peanut plant can be formed, so that the nutrient utilization rate can be increased; and the integrated mechanized operation of tillage, fertilizer application and seeding of the peanuts can be realized, the application amount of chemical fertilizer for the peanuts can be reduced, organic matters can be increased, and a fertilizer application mode combining the planting and maintaining of peanuts can be realized.

Description

technical field [0001] The invention belongs to the field of fertilizer preparation, and in particular relates to a preparation method and large-scale application of an organic block fertilizer special for peanuts. Background technique [0002] Peanut is an important oil crop, which provides edible oil and protein for residents, and is also an important raw material for food and medicine. It is planted in most provinces of my country, covering about 4.727 million hectares, accounting for 48.03% of the global total output. However, the soil where peanuts are grown is mainly sandy soil, with loose soil, poor structure, and serious nutrient loss, which is likely to cause serious environmental pollution problems; and excessive fertilization will further lead to a decline in soil fertility. Therefore, it is extremely important for the development of my country's peanut industry to develop special fertilizers suitable for peanut planting characteristics. [0003] The technology r...
