Composite growth regulator for increasing yield and saccharinity during sugar accumulating period of beetroot and usage

Abstract

The invention relates to a composite growth regulator for increasing yield and saccharinity during the sugar accumulating period of beetroot and a usage, which are particularly suitable for the application under the arid environment, and have obvious effect on increasing yield and saccharinity through the foliage spray in late August. The regulator can not only control the injury caused by the stress of the environment, and keep the duration of the function foliage at the maximum, but also increase the activity of sucrose synthase, reduce the consumption of glycogen, promote coordination and uniform of the beetroot and the environment, individual and group, root and overground part, the external shape of the plant and internal physiological function during the sugar accumulating period, and finally reach the goal of improving the yield and saccharinity. Under the environment of the west of Jilin province, with less than 300 mm of the amount of precipitation, 0.47 percent of salt content and PH value of 8.6, the yield of beetroot reaches to 52,766.25kg / hm2, the yield is increased by 12.18 percent, and the sugar content is 17.0 percent, which is increased by 1.4 percent.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a stress-resistant, yield-increasing, sugar-increasing compound growth regulator for the sugar beet accumulation period and its usage. Background technique [0002] Sugar beet is not only a sugar raw material, but also an important raw material for the production of ethanol. China's beet planting areas are mainly distributed in the "Three North" regions. Due to the impact of salinity, drought and the spread of diseases, the yield and sugar content of beet are decreasing year by year. Especially in September, sugar beet is under extreme drought stress, and this time is the main period of sugar beet accumulation. Drought stress causes premature senescence of functional leaves and seriously affects the transport and accumulation of photosynthetic products (mainly sucrose) to roots. One of the most effective and feasible technical measures to solve this problem is...

AI Technical Summary

Problems solved by technology

[0006] Although there are many research results based on the literature, such research results have limited effects on increasing sugar content and root yield, and cannot cope with complex environmental stresses, making raw materials such as those produced in all sugar beet producing areas in China's "Three North" regions Low sugar content and low yield, unable to meet the needs of sugar refineries and ethanol plants

[0007] At present, marginal land such as saline-alkali land, hillside land, and sandy wasteland in my country's "Three North" regions has not been effectively developed for a long time, and the sugar industry and fuel ethanol industry have huge potential demand for resources and serious shortage of actual supply.
