Problems solved by technology

Most planting areas in Xinjiang are rich in potassium and relatively lacking in phosphorus. At the same time, considering the annual fertilizer consumption in Xinjiang, for example, in 2009, the annual consumption of nitrogen, phosphorus and potassium fertilizers in Xinjiang reached 1.5628 million tons, of which The amount of pure nitrogen accounts for 47.62%, the amount of pure phosphorus accounts for 24.93%, and the amount of pure potassium accounts for 5.82%. According to the principle of soil testing and formula fertilization, it is obvious that the compound fertilizer of the above patent has an unreasonable ratio of nitrogen, phosphorus, and potassium in the planting areas of Xinjiang.

Abstract

The invention discloses a long-acting compound fertilizer. The long-acting compound fertilizer comprises large granule urea, monoammonium phosphate, potassium sulfate and filler, and is prepared by uniformly mixing large granule urea, monoammonium phosphate, potassium sulfate and filler in a mass ratio of (400-426): (360-367) : (163-172) : (60-65). The filler is a particle prepared from small granule urea, ammonium sulfate, calcium carbonate and long-acting compound fertilizer additive in a mass ratio of (210-220): (190-210) : (540-550) : (35-45). The long-acting compound fertilizer increases utilization rate of nitrogen element, realizes equalized nutrients of nitrogen, phosphor and potassium and is suitable for usage of different crops in different plantation regions in Xinjiang. The invention has active realistic significance in increasing crop output, reducing agriculture production cost, fertilizer waste and quantity of work, and increasing income of peasants.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a long-acting compound fertilizer applied to crops. Background technique [0002] Cotton, corn, and tomato are the main crops in Xinjiang. Among them, the cotton planting area and total output have ranked first in the country for many years. In 2009, the corn planting area reached 8.976 million mu. In 2010, the tomato planting area reached 1.605 million mu. 90% of the total, there is a huge demand for nitrogen, phosphorus and potassium fertilizers. [0003] Compound fertilizers refer to fertilizers in which at least two or more of the three nutrients nitrogen, phosphorus, and potassium are produced by chemical methods and / or blending methods. Compound fertilizers contain the nutrients needed for the growth of various crops, and can greatly reduce the labor intensity of farmers. Therefore, the promotion of the application of compound fertilizers in Xinjiang is the trend of modern agricult...
