Composite growth regulator for beet stress-resistant yield and sugar-increased seedling stage and using method thereof

Abstract

The invention relates to a composite growth regulator for beet stress-resistant yield and sugar-increased seedling stage and a using method thereof. The composite growth regulator is prepared from plant hormone, Ca2 and various signal substances, is particularly suitable for saline and arid environment conditions, and can induce the expression of beet stress-resistant genes and accelerate coordination and unification between the beet and the environment, the individual and population, the root and the overground part, the external form of the plant and internal physiological function. After the beet is transplanted, the salinization resistance, drought resistance and disease resistance can be effectively enhanced; and the problem that the beet yield and the sugar content resulted from the influence of salinization, drought and disease spreading are reduced year by year is solved. The regulator also has the characteristics of a common strong-seedling agent and also can solve the problems of vain growth, disease susceptibility and weak seedlings of the young seedlings in the beet seeding culture process; the beet root yield under the saline and arid environment conditions reaches 47,267.47kg / hm<2>, the yield is increased by 16 to 18 percent; the sugar content is 16.1 percent, and is increased by 0.9 to 1.2 percent; and the effects of increasing the yield and sugar are obvious.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a sugar beet compound growth regulator at the seedling stage for stress resistance and yield increase 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. Cultivated sugar beet is gradually cultivated from wild common sugar beet (B. Vulgaris) under the action of artificial selection. Wild common beets originated in West Asia, the Mediterranean coast and Western Europe, and possess various resistance genes. After more than 200 years of artificial cultivation, sugar beet has adapted to grow and develop under comfortable conditions, so that some stress resistance functions have gradually declined, and some genes have gradually become dormant due to long-term lack of full expression, becoming so-called recessive genes. Modern scientific research shows that as lon...

Problems solved by technology

At present, although plant growth regulators such as Fengyisu and Penshibao have appeared on the market, they cannot effectively induce the expression of stress-resistant genes due to their single hormone components or their lack of specificity to sugar beets, which leads to post-transplanting plant growth regulators. sugar beets have very limited resistance to salinity, drought and pathogenic infection

[0006] At present, marginal land such as saline-alkali land, hillside land, and sandy wasteland in the "Three Norths" region of my country has not been effectively developed for a long time, and the sugar industry and biomass conversion have a huge potential demand for resources and a serious shortage of actual supply.
