Embodiment 1

[0018] Using mixtures of different proportions and different contents and single doses to treat crops, the rationality of the mixture was measured by measuring the average panicle length, thousand-grain weight, and yield increase rate of the crops in the late stage and the blank control area.

[0019] The 28-homobrasinolide technical drug and DA-7 were respectively made into mother liquors with acetone and Tween-80, and the potted rice was tested, and the leaves were sprayed at the tillering stage and the booting stage of the rice respectively. The test results are shown in Table 1.

Embodiment 2

[0029] A complex plant growth regulator, the active ingredient consists of the following components by weight: 0.01 part of 28-homobrassinolide and 1.99 parts of DA-7.

[0030] The method for preparing the above-mentioned pesticide composition comprises uniformly mixing the raw materials in the weight ratio, and preparing a soluble agent with an active ingredient mass percentage of 2% with the adjuvants allowed on the pesticide according to a conventional preparation method.

Embodiment 3

[0032] A complex plant growth regulator, the active ingredient is composed of the following components by weight: 0.005 part of 28-homobrassinolide and 9.995 part of DA-8.

[0033] The method for preparing the above-mentioned pesticide composition comprises uniformly mixing the raw materials in the weight ratio, and preparing a soluble powder with an active ingredient mass percentage of 10% with the adjuvants allowed on the pesticide according to a conventional preparation method. 1. Purpose: To test the effect of the compound plant growth regulator developed by the present invention on the growth and yield of rice or wheat.

Abstract

The invention relates to a compound plant growth regulator containing brassinolide and DA-7 or DA-8, wherein the effective components are brassinolide and DA-7 or DA-8, the weight percentage of brassinolide in the compound plant growth regulator is 0.001%-1%, and the weight percentage of DA-7 or DA-8 in the compound plant growth regulator is 1%-20%. The plant growth regulator can be processed into a soluble concentrate or soluble powder in practical application; the plant growth regulator has good growth promoting and yield increasing effects on rice, wheat and vegetables.

Description

【Technical field】 [0001] The invention relates to the field of a compound plant growth regulator. The active ingredients include brassinolide and DA-7 or DA-8, and are mainly used to regulate the growth of rice, wheat, vegetables and other crops. 【Background technique】 [0002] Brassinolides are one of the steroidal compounds with high biological activity. They are widely present in plants. In all stages of plant growth and development, they can not only promote vegetative growth, but also facilitate fertilization. The synthetic Brassica The activity of steroid lactone is relatively high, which can be absorbed by the leaves, stems and roots of plants, and then transmitted to the site of action. Some believe that it can increase the activity of RNA polymerase, increase the content of RNA and DNA, and some believe that it can increase the concentration of cell membranes. Potential difference, ATPase activity, and some believe that it can strengthen the effect of auxin, but the...
