Formulated fertilizer specially used for cotton

Abstract

The invention relates to a formulated fertilizer specially used for cotton. The formulated fertilizer comprises the following effective elements in percent by weight in terms of pure components: 18-22% of nitrogen, 6-10% of phosphorus pentoxide, 12-14% of potassium oxide, 0-2% of calcium, 0-2.5% of sulphur, 0.5-1% of zinc, 0.2-0.6% of boron and 5-10% of organic matter; and the effective elements in the formulated fertilizer are respectively provided by the following substances: urea or / and diammonium phosphate or / and ammonium chloride or / and ammonium sulphate for nitrogen, diammonium phosphate or / and calcium superphosphate for phosphorus pentoxide, potassium chloride for potassium oxide, calcium superphosphate for calcium, calcium superphosphate or / and zinc sulphate monohydrate for sulphur, zinc sulphate monohydrate for zinc and borax for boron. According to the formulated fertilizer specially used for cotton provided by the invention, the characteristic of nutrient supply of cotton planting soil in China is considered, and macroelement, medium element and microelement nutrients are matched in appropriate proportion, so that yield of cotton is improved, quality of cotton fiber is improved, fertilizer utilization rate and economic benefit are improved, and negative effects of a fertilizer to the environment are reduced.

Problems solved by technology

[0005] In terms of fertilizer application technology, although the combination of organic fertilizer and inorganic fertilizer has been created to apply sufficient base fertilizer, early application of light seedling fertilizer, skillful application of bud fertilizer, heavy application of flower and boll fertilizer, supplementary application of capping fertilizer, soil test formula fertilization, one-time full application A series of fertilization technologies such as layer fertilization, but because the current labor force engaged in cotton production is small and mostly old people, women and children, with low cultural and technological quality, poor ability to accept new technologies, and the instability of grassroots agricultural technology extension teams, good fertilization Difficult to apply the technology
