Embodiment 1
[0038] Ingredients: 400 parts of urea, 50 parts of diammonium phosphate, 100 parts of potassium dihydrogen phosphate, 150 parts of potassium sulfate, 150 parts of calcium humate, 50 parts of calcium magnesium phosphate fertilizer, 30 parts of magnesium sulfate, 10 parts of zinc sulfate, high-strength water-retaining agent 10 parts, 50 parts of filler.
[0039] Preparation Process:
[0040] (1) Melt 400 parts of urea at high temperature (130°C-140°C), enter the buffer tank, pressurize it through the delivery pump, and pump it into the top mixer.
[0041] (2) 50 parts of diammonium phosphate, 100 parts of potassium dihydrogen phosphate, 150 parts of potassium sulfate, 150 parts of calcium humate, 50 parts of calcium magnesium phosphate fertilizer, 30 parts of magnesium sulfate, 10 parts of zinc sulfate, and 10 parts of high-strength water-retaining agent , 50 parts of filler, after metering, send it into the mixer and mix well. After the mixed raw materials are crushed and scr...

Abstract
The invention discloses special cotton fertilizer for regulating and controlling coastal saline-alkali land soil and belongs to the technical field of special fertilizers for crops. The special cotton fertilizer is prepared from the following raw materials in parts by weight: 300-450 parts of urea, 1-100 parts of diammonium phosphate, 50-120 parts of potassium dihydrogen phosphate, 100-200 parts of potassium sulfate, 50-150 parts of calcium humate, 1-50 parts of calcium-magnesium phosphate, 1-50 parts of magnesium sulfate, 1-10 parts of zinc sulfate and 1-10 parts of high-strength water retention agent. Compared with the prior art, the special cotton fertilizer has the advantages that due to the addition of water-soluble calcium humate, the special cotton fertilizer can be used for inhibiting salt and holding moisture; due to the addition of a proper volume of water retention agent, the special cotton fertilizer can be used for regulating and controlling water retention, increasing the fertilizer effect and increasing fertilizer utilization ratio; due to the addition of essential secondary / trace elements, the resilience resistance is enhanced, and the product yield and quality are improved.
Description
technical field [0001] The invention belongs to the technical field of special fertilizer for crops, and in particular relates to a special fertilizer for regulating cotton in coastal saline-alkali land soil. [0002] Background technique [0003] The coastal saline-alkali land in my country's cotton-growing areas is mainly saline soil and saline soil. There are more than 20 million mu of coastal saline-alkali land that has been planted with cotton or is yet to be developed. The development of coastal saline-alkali land for cotton planting is of great significance for improving cotton production capacity and alleviating the conflict between grain and cotton for land. However, cotton planting in saline-alkali land has long-term prominent problems such as difficulty in seedling formation, difference in maturity, more labor, large investment, and low yield and benefit. In response to these problems, according to the regulation idea of "reasonable fertilization, salt suppress...
