Foliar fertilizer special for sugarcane

Abstract

The present invention relates to a formula of foliar fertilizer special for sugar canes. According to the weight portions, the foliar fertilizer contains 30 portions of potassium dihydrogen phosphate, 40 portions of borax, 16 portions of magnesium sulfate, 10 portions of zinc sulfate and 4 portions of ammonium molybdate. The foliar fertilizer can effectively solve the problems of nutrient balance, output and low sugar in the sugar canes. Tests have proven that the fertilizer can effectively increase the unit yield of the sugar canes by 0.3 to 0.8 ton per mu, increase the sugar component of the sugar canes by 0.5 to 1.0 percent, and improve the tillering rate and stalk efficiency of the sugar canes. At the same time, the foliar fertilizer can improve the quality of the sugar canes, lower the fiber component of the sugar canes by 0.5 to 1 percent, lower the content of reducing sugar, and increase the gravity purity of sugarcane juice by 1 percent. Thus the foliar fertilizer is more suitable for tropical zones and semi-tropical zones of sugar canes in the southern China. In the preparation method of the foliar fertilizer special for the sugar canes, the fertilizers of the potassium dihydrogen phosphate, the borax, the magnesium sulfate, the zinc sulfate, and the ammonium molybdate are purchased from the market and are required to be qualified for the national standards of fertilizer production. The fertilizers are mixed, crushed uniformly, screened by a 5-millimeter sieve, and bagged; thus the product can be prepared.

Description

Technical field: [0001] The invention relates to a special leaf fertilizer for sugarcane. Background technique: [0002] 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. The lack 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 specific to sugarcane, and have no obvious promotion effect on sugarcane yield, sugar content, tillering rate, stem forming rate, etc. Invention content: [0003] The purpose of the present invention is to provide a special leaf fertilizer for sugarcane, which can effectively solve the problems ...

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.
