Problems solved by technology

But its shortcomings are: first, borax is in powder form, and it is not easy to mix with other granular raw materials directly; Fertilizer effect: Borax is a quick-acting fertilizer, which may be lost due to irrigation, rainfall, etc., and cannot meet the boron nutritional needs of peanuts in the later stage
Furthermore, this fertilizer does not contain calcium fertilizer, which cannot solve the serious production and quality problems of peanuts caused by calcium deficiency

Abstract

The invention relates to a calcium and boron efficient compound special controlled-release fertilizer for peanuts as well as a preparation method and application thereof. The special controlled-release fertilizer for peanut is prepared from the following raw materials in part by mass: 120-200 parts of controlled-release calcium fertilizer, 180-280 parts of boracic weathered coal coated urea, 50-150 parts of sulfur and high-molecular polymer coated urea, 280-350 parts of diammonium phosphate and 120-250 parts of granular potassium sulfate. The invention also provides a preparation method and application of the special controlled-release fertilizer for peanut. According to the invention, an inorganic calcium fertilizer is combined with turf to promote the effective utilization of calcium; the boron is coated for dispersion; and the special controlled-release fertilizer for the peanuts can meet the requirement on the absorption proportion of the nutrients calcium and boron in the growth and development process of peanut, and can be used for increasing the output and improving the nut quality.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for calcium and boron complex peanuts and its preparation method and application, belonging to the technical field of production and application of controlled-release fertilizers. Background technique [0002] Peanut is an important oil crop and economic crop in my country, its planting area ranks second in the world, and its total output ranks first in the world. Peanut is a traditional export commodity in our country. The high yield and high quality of peanut are of great significance to our national economy. [0003] Peanut is one of the crops that require the most calcium nutrition. Compared with other crops with the same yield level, it is about 5 times that of rice and 7 times that of wheat. The amount of calcium absorbed by peanuts is second only to nitrogen and potassium, and is the third nutrient element. According to research, due to calcium deficiency in our soil, the peanut ...
