Special leaf fertilizer for sugarcane and preparation method thereof

Abstract

The invention discloses a special leaf fertilizer for sugarcane and a preparation method thereof. The leaf fertilizer contains, by weight, 30 parts of potassium dihydrogen phosphate, 40 parts of borax, 16 parts of magnesium sulfate, 10 parts of zinc sulfate and 4 parts of ammonium molybdate. The leaf fertilizer can effectively solve the problems of nutrient balance, low yield and low sugar content. Experiments show that the fertilizer can improve the yield of sugarcane by 0.3-0.8 tons / acre and the sugar content by 0.5-1 percentage point, increase the tillering rate and stem ratio of sugarcane, improve the quality of sugarcane, reduce the fiber by 0.5-1 percentage point and the reducing sugar content and increase gravity purity of sugarcane juice by 1 percentage point, and is more suitable for the widespread usage in tropical and subtropical sugarcane areas in the south of China. The preparation method of the special fertilizer for sugarcane is as below: purchasing potassium dihydrogen phosphate, borax, magnesium sulfate, zinc sulfate, and ammonium molybdate chemical fertilizers from the market, wherein the fertilizers must have qualified quality complying with the requirements of national chemical fertilizer production standard; mixing and crushing the chemical fertilizer uniformly; sieving through a 5 mm screen, and packaging to obtain the finished product.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a special leaf fertilizer for sugarcane and a preparation method thereof. [0002] Background technique [0003] Sugarcane is an important sugar crop in my country. It has a long growth cycle and requires a large amount of fertilizer. The sugarcane area has only focused on the application of nitrogen fertilizers for many years, but little supplementation of nitrogen, phosphorus, potassium, magnesium and some trace element fertilizers. Difficult to promote in production. Deficiency of essential nutrients and insufficient supplementation of nutrients in the soil ultimately lead to low sugarcane yield and sugar content. Existing economic crop foliar fertilizers are not highly targeted to sugarcane, and the promotion effects on sugarcane yield, sugar content, tillering rate, stem forming rate, etc. are not obvious. Contents of the invention [0004] The purpose of this in...

AI Technical Summary

Problems solved by technology

For many years, the sugarcane area has only paid attention to the application of nitrogen fertilizer, but there is little supplement for nitrogen, phosphorus, potassium, magnesium and some trace element fertilizers. Difficult to promote in production

Deficiency of essential nutrients and insufficient supplementation of nutrients in the soil ultimately lead to low sugarcane yield and sugar content

Existing economic crop foliar fertilizers are not very specific to sugarcane, and have no obvious promotion effect on sugarcane yield, sugar content, tillering rate, and stem formation rate.
