Special fertilizer having high nutrient utilization rate and used for figs

Abstract

The invention discloses special fertilizer having a high nutrient utilization rate and used for figs. The special fertilizer is prepared from raw materials in parts by weight as follows: 85-90 parts of a main material, 0.5-1.2 parts of diaminoferric xanthohumate, 0.1-0.6 parts of manganese humate, 0.2-1 part of zinc humate, 0.3-1.2 parts of calcium humate, 2-4 parts of borax and 90-100 parts of organic fertilizer, wherein the main material is prepared from, in parts by weight, 40-55 parts of coated urea, 15-35 parts of triple superphosphate and 12-18 parts of sylvine; the coated urea is prepared with a process as follows: glycerin, p-toluenesulfonic acid, epoxidized soybean oil and an ethanol solution are mixed uniformly, heated under the protection of nitrogen and stirred, nitrogen protection is removed, the mixture is cooled, urea, sodium carboxymethylcellulose and glycerol laurate critrate are added, the mixture is stirred and subjected to spray drying, and the coated urea is obtained. The special fertilizer has balanced nutrition and long effective period and can short the flowering period and the fruiting time of the figs, the harvesting time of the figs is greatly shortened, and the economic benefits of the figs are well increased.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for figs with high nutrient utilization rate. Background technique [0002] To keep the soil fertile, the inorganic nutrients and nitrogen absorbed by plants and removed from the farmland must be returned to the soil in the form of fertilizer. In 1843, the world's first chemical fertilizer, superphosphate, was successfully developed. With the discovery of saltpeter and potash mines in Chile, and the invention of synthetic ammonia, a huge fertilizer industry was established in the world. [0003] Fertilizer is a kind of substance that provides one or more essential nutrients for plants, improves soil properties, and improves soil fertility. It is one of the material basis of agricultural production. At present, there are many types and brands of fertilizers on the market, but the fertilizers for figs have the problem of low nutrient utilization, which nee...
