Problems solved by technology

[0002] China's chemical fertilizer production accounts for about 17.5% of the world, and this figure is still growing every year. The use of chemical fertilizers accounts for 27.2% of the world, ranking first in the world. The amount of chemical fertilizer per unit of farmland is twice that of the United States and Russia, but The utilization rate of chemical fertilizers is very low, only 30% to 50%, and the remaining 65% to 70% are lost in vain, especially the potassium element in the fertilizer. The lost potassium element not only reduces the fertilizer efficiency of the fertilizer, but also easily damages the soil, water pollution

Embodiment 3

[0031] A slow-release biological potassium fertilizer made of the following raw materials in parts by weight: urea, 150; potassium nitrate, 530; potassium dihydrogen phosphate, 125; potassium chloride, 160; borax, 20; zinc sulfate, 10; sulfuric acid Manganese, 5; chitosan, 15; sodium nitrophenolate, 1; bright yellow pigment, 2.

[0032] Described chitosan is processed by following steps:

[0033] Add dilute hydrochloric acid to the shrimp and crab shells for the first decalcification, and then add water to wash the shrimp and crab shells after the first decalcification, and continuously measure the pH value of the shrimp and crab shells until the pH is ≥ 6, and then add dilute alkali for decalcification. Deproteinize for the first time, and control the solution temperature at 85°C, then wash with water, the pH of the water wash is ≤ 8, then add dilute hydrochloric acid, wash with water, add dilute alkali, and wash with water for the second decalcification and second deproteini...

Abstract

The invention discloses slow release type biological potassium fertilizer, which is prepared from the following raw materials in parts by weight: 140 to 160 parts of urea, 500 to 540 parts of potassium nitrate, 120 to 130 parts of potassium dihydrogen phosphate, 150 to 170 parts of potassium chloride, 18 to 25 parts of borax, 9 to 12 parts of zinc sulfate, 4 to 6 parts of manganese sulfate, 12 to 16 parts of chitosan, 1 part of compound sodium nitrophenolate and 2 parts of bright yellow pigment. Besides meeting the nutritional requirement of the healthy and quick growth of a crop, the specially added chitosan also has the effects of preventing a disease, resisting stress, improving soil, ameliorating quality and inhibiting nematodes; meanwhile, multiple trace elements are added; the nutritional requirement during the whole growth period of the crop can be met; the utilization rate of a potassium element is particularly increased; the decrement of an application amount is facilitated; the destroy to an environment is decreased as much as possible; flower-falling, fruit-falling and leaf-falling phenomena are effectively prevented; a plant can be prevented from premature senescence.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a slow-release biological potassium fertilizer. Background technique [0002] China's chemical fertilizer production accounts for about 17.5% of the world, and this figure is still growing every year. The use of chemical fertilizers accounts for 27.2% of the world, ranking first in the world. The amount of chemical fertilizer per unit of farmland is twice that of the United States and Russia, but The utilization rate of chemical fertilizers is very low, only 30% to 50%, and the remaining 65% to 70% are lost in vain, especially the potassium element in the fertilizer. The lost potassium element not only reduces the fertilizer efficiency of the fertilizer, but also easily damages the soil, Water sources are polluted. In terms of year-on-year input, the increase in grain production is far behind that of Western developed countries, with an increase of only 9.1%. On the premise ...
