Description
Technical Field
The invention relates to the technical field of agricultural production, and particularly relates to a stigmasterol stress-resistant growth promoter and a preparation method thereof.
Background
Sterols (also called sterols), which are a class of steroids, are hydroxyl-containing steroids. They are called steroid compounds because they have a basic structure of cyclopentanoperhydrophenanthrene and contain hydroxyl groups. Sterols are important natural active substances widely existing in organisms, and are classified into three major groups, namely, animal sterols, plant sterols, and fungus sterols, according to the raw material sources. The animal sterol is mainly cholesterol, the plant sterol is mainly sitosterol, stigmasterol, campesterol and the like, and the ergosterol belongs to fungus sterol. The phytosterol can promote the dissimilation of cholesterol, inhibit the biosynthesis of cholesterol in liver, and inhibit the absorption of cholesterol in intestinal tract, thereby preventing cardiovascular diseases. Cholesterol is also an important component of cell membranes and participates in the transport of lipids in the blood in the human body. The phytosterol has the function of blocking carcinogen from inducing cancer cell formation, and the phytosterol such as beta-sitosterol has certain inhibition effect on the occurrence of colorectal cancer, skin cancer and cervical cancer. The largest function of phytosterol is the hormone-like function of 'intelligent management', which can show a certain hormone activity in the body but has no side effect of hormone, when the level of the human hormone is higher than the normal value, the phytosterol 'works', shows the function of hindering the absorption of the cholehormone, reduces the level of the human hormone, and when the level of the human hormone is lower than the normal value, the phytosterol 'converts' all the hormones of the adult body, improves the level of the human hormone, thereby achieving balance. Stigmasterol is one of the sterols. The stigmasterol is obtained by physical purification, and has the characteristics of high nutritive value, strong physiological activity and the like. It has wide application in medicine, cosmetics, animal growth promoter, paper processing, printing, textile, food and other fields. However, in the field of promoting plant growth in agriculture, few studies have been made.
With the increasing of industrial land year by year, available cultivated land is in a trend of decreasing, and more prominently, rural labor is transferred to cities, so that agricultural grain production is seriously influenced. More seriously, with the use of a large amount of chemical fertilizers in agricultural planting, salinization of the soil is increasingly serious, the air permeability of the soil is poor, beneficial microorganisms in the soil are greatly reduced, particularly, the accumulation of a large amount of salt in the soil seriously influences the synthesis of the steroid compounds of the crops, reduces the steroid substances in the plants, causes the growth speed of the crops to be disordered, and the crops grow slowly, thereby influencing the yield of the crops.
Therefore, how to solve and overcome the side effects caused by the side effects becomes an important subject of agricultural scientists.
