A kind of composite fertilizer compounded in different growth periods of bananas

Abstract

The invention provides combined fertilizers prepared in different growth periods of bananas through compounding. The combined fertilizers comprise fertilizers in the following five periods: seedling period of bananas, vigorous growth period of bananas, flower bud differentiation period of bananas, young fruit period of bananas and maturation period of bananas, wherein a formula fertilizer in the seedling period of bananas comprises urea, calcium magnesium phosphate and potassium chloride in a mass ratio of (0.8-1.2) to (2-3) to (0.8-1.2); a formula fertilizer in the vigorous growth period of bananas comprises urea, calcium magnesium phosphate, potassium chloride and magnesium sulfate in a mass ratio of (0.8-1.2) to (0.2-0.4) to (1.0-1.8) to (0.05-0.1); a formula fertilizer in the flower bud differentiation period of bananas comprises urea, potassium chloride and magnesium sulfate in a mass ratio of (0.7-1.2) to (2.0-3.0) to (0.20-0.28); a formula fertilizer in the young fruit period of bananas comprises urea, potassium chloride and magnesium sulfate in a mass ratio of (0.7-1.3) to (2.0-3.5) to (0.14-0.18); a formula fertilizer in the maturation period of bananas comprises urea and potassium chloride in a mass ratio of (0.8-1.2) to (1.5-2.5).

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a composite fertilizer compounded in different growth stages of bananas. Background technique [0002] Banana is the most important tropical fruit in the world, ranking among the four major fruits in the world. In my country, it is mainly distributed in tropical and subtropical regions such as Hainan, Guangzhou, Guangxi and Yunnan. At the same time, the economic benefits of bananas depend largely on the yield and quality of bananas, and reasonable fertilization during banana planting can improve the yield and quality of bananas. [0003] The current special fertilizer for fertilizing bananas is mainly aimed at the nutritional needs of the whole growth period of bananas, and cannot meet the nutritional needs of bananas in each growth period. At the same time, a large amount of nitrogen fertilizer is applied at the banana seedling stage, causing inorganic nutrients...

AI Technical Summary

Problems solved by technology

[0004] Bananas have a long growth period and require a large amount of fertilizer. The growth period of bananas can be roughly divided into five key growth periods: seedling stage, vigorous growth stage, flower bud differentiation stage, young fruit stage, and mature stage. The fertilizer required for each stage There is a large difference in the ratio and amount. It is unscientific to apply the same ratio or arbitrarily compared with the mixed fertilizer in general. It cannot meet the growth needs of bananas, and it also results in the increase of banana inorganic nutrient input costs and the increase in yield, reduction in quality
