Problems solved by technology

[0002] Cotton is an important economic crop. In order to achieve high yield of cotton, there must be sufficient fertilizers in each growth period. However, the existing special fertilizers for cotton cannot be released slowly, resulting in uneven fertility release during the growth period of cotton, which cannot meet the needs of cotton growth. , and after the existing cotton fertilizer is applied, a large amount of it is lost, on the one hand, it is wasted, and on the other hand, it also causes environmental pollution. In order to solve the above-mentioned drawbacks

Abstract

A special slow release fertilizer for cotton is prepared from, by weight, 15-25 parts of urea, 4-6 parts of ammonium chloride, 6-8 parts of potassium chloride, 3-5 parts of phosphorus pentoxide, 4-6 parts of brown sugar, 1-3 parts of zinc oxide, 1-3 parts of ammonium molybdate, 4-6 parts of plaster of paris, 5-7 parts of meerschaum, 2-4 parts of iron-ore slag, 2-4 parts of borax and 4-6 parts of water. Various nutritional ingredients can be slowly released, no nutrition runs off, the fertilizer is applied once, topdressing is not needed, environmental pollution is avoided, and the yield of the cotton is increased.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special slow-release fertilizer for cotton. Background technique [0002] Cotton is an important economic crop. To achieve high yield of cotton, there must be sufficient fertilizers in each growth period. However, the existing special fertilizers for cotton cannot be released slowly, resulting in uneven fertility release during the growth period of cotton, which cannot meet the needs of cotton growth. , and the existing cotton fertilizer is lost in a large amount after application, which is wasted on the one hand, and also causes environmental pollution on the other hand, in order to solve the above-mentioned drawbacks. [0003] The invention develops a special slow-release fertilizer for cotton, which can meet the needs of several main nutrient elements for the growth and development of cotton, has the functions of strongly activating soil, breaking compaction, increasi...
