Application of melatonin in improvement of sugar content of sugarcane

Abstract

The invention relates to an application of melatonin in the improvement of the sugar content of sugarcane. Melatonin or a product containing melatonin is sprayed on sugarcane leaf surfaces in the early maturation stage of a sugarcane process to promote sugarcane sugar accumulation and increase the sugar content of sugarcane in order to achieve early maturation of sugarcane, so the sugarcane can beharvested early, and the application range of the melatonin is widened; and the melatonin has the advantages of safety, non-toxicity, no adverse effects on the growth of the sugarcane and other crops, no influence on the yield of the sugarcane, low product cost, small dosage, and realization of time and labor saving, convenience and high efficiency through spraying using an unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the field of cultivation and management of plants of the genus Saccharum, in particular to the application of melatonin in increasing the sugar content of sugarcane. Background technique [0002] Sugarcane is a plant of the Gramineae Saccharum genus. It is a plant with high light efficiency, high light saturation point, high photosynthetic intensity, and high biological yield. Sugarcane is the most important sugar crop in China, with a long growth cycle. The sugarcane sugar extraction season in my country is generally from autumn to the spring of the next year. If the sugarcane is not mature enough or overripe when harvested, the sugar content of the sugarcane will be insufficient or reduced. , affecting sugar production. There are certain differences in the maturity stages of different varieties of sugarcane. The sugar content of early-maturing varieties accumulates quickly, and the sugar content of the sugarcane is already hi...

AI Technical Summary

Problems solved by technology

Most of the sugarcane areas in China are dominated by uneven terrain such as semi-sloping land and mountains. In addition, the sugarcane plants are tall, and manual and ordinary mechanical spraying are difficult to operate. It is also difficult to popularize and apply foreign artificially piloted aircraft.

On the other hand, the agent itself has an inhibitory effect on sugarcane growth, so it will have some negative effects on yield

If it drifts to other crops when spraying, it may cause the growth of other crops to be affected
