Abstract

The invention discloses a compound plant growth regulator and application thereof. The compound plant growth regulator comprises, by weight, 0.001-1.0 part of brassinolide, 10-20 parts of a brown algaextract, 15-35 parts of a reynoutria sachalinensis extract, 15-35 parts of a radix curcumae extract, 10-20 parts of a mimosa pudica extract and 10-20 parts of an oak stem and leaf alcohol extract. According to the growth regulator, the environment-friendly growth regulator brassinolide compound is combined with the medicine materials and plant extracts, and all the medicine components have a sufficient synergistic effect; the growth regulator has a effect of restraining various bacteria, fungi and viruses and has remarkable effects of effectively promoting the growth and development of vegetable crops (cucumbers, chilli, tomatoes or the like) and the absorption and transferring of nutrients, prompting the crop maturity and improving the color, luster, sugar degree and appearance glossiness.

Description

technical field [0001] The invention relates to the technical field of agricultural growth regulators, in particular to a composite plant growth regulator and its application. Background technique [0002] my country's cucumber cultivation area accounts for more than 60% of the total vegetable cultivation area. Cucumber cultivation in northern winter and spring must be carried out in protected areas. Due to the influence of low temperature, short sunshine, weak light, etc., the growth potential of cucumber plants is weak, the fruit expands slowly, and growth is hindered. Moreover, cucumbers form a large number of female flowers under low temperature and short sunshine conditions. , It is easy to cause low fruit setting rate, which seriously affects the cucumber yield and the economic benefits of growers. The use of chemical regulation technology is one of the convenient and effective ways to promote cucumber yield. At present, the growth regulators used are mainly chemical...
