Problems solved by technology

The artificially synthesized brassinolide has high activity, 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 It is believed that it can increase the potential difference of the cell membrane and the activity of ATPase, and some believe that it can strengthen the effect of auxin. There is no unified view on the mechanism of action.

Embodiment 1

[0012] Embodiment 1: indoor synergy test

[0013] Sun Yunpei method to calculate co-toxicity coefficient (CTC). Co-toxicity coefficient (CTC) ≥ 120 represents synergistic effect; co-toxicity coefficient (CTC) ≤ 80 represents antagonism; 80 < co-toxicity coefficient (CTC) < 120 represents additive effect.

[0014] Measured Toxicity Index (ATI) = (standard drug EC 50 / Test agent EC 50 )×100.

[0015] Theoretical toxicity index (TTI) = (toxicity index of A × percentage of A in the mixture) + (toxicity index of B × percentage of B in the mixture).

[0016] Co-toxicity coefficient (CTC)=[mixture measured toxicity index (ATI) / mixture theoretical toxicity index (TTI)]×100 will 95.4% furfuryl aminopurine (Kinetin), 95.5% brassinolide (brassinolide) After the original drug is folded, acetone and Tween-80 are used to make 1.6 μg / mL mother liquor, and the mother liquor is used to prepare furfurylaminopurine and brassinolide in a mass ratio of 1:30-30:1, respectively. The specific da...

Embodiment 2

[0023] Example 2: 1% furfuraminopurine brassinolide soluble powder

[0024]

[0025] After the above-mentioned raw materials are uniformly mixed, and then air-jet pulverized, the 1% furfuraminopurine-brassinolide soluble powder can be prepared.

Embodiment 3

[0026] Example 3: 0.5% furfurylaminopurine brassinolide soluble solution

[0027]

[0028]

[0029] After stirring and dissolving the above active ingredients with a solvent, other additives are added, fully stirred and mixed uniformly, and a 0.5% furfuraminopurine brassinolide soluble agent can be prepared.

Abstract

The invention relates to a plant growth regulator containing furfurylaminopurine and brassinolide. The plant growth regulator comprises furfurylaminopurine, brassinolide and additives, wherein the weight ratio of the furfurylaminopurine to the brassinolide is (1 to 30)-(30 to 1); the total weight of the furfurylaminopurine and the brassinolide accounts for 0.01-20% of the weight of the plant growth regulator. The plant growth regulator can be processed into solutions or soluble powder in practical application; a large quantity of field trials prove that the plant growth regulator has excellent growth-promoting and yield-increasing effects on crops such as rice, wheat, cucumber and tomatoes.

Description

technical field [0001] The invention relates to a plant growth regulator containing furfuryl aminopurine and brassinolide, which is suitable for promoting growth and increasing production of rice, wheat, cucumber, tomato and other crops. Background technique [0002] Furfurylaminopurine belongs to cytokinins, plant endogenous hormones exist in plant seeds, roots, stems, leaves, young meristems and developing fruits. It is mainly secreted from the root tip and transmitted to other parts to stimulate cell division, promote the formation of chlorophyll, and prevent premature aging and fruit shedding. Promote photosynthesis and protein synthesis, promote flower bud differentiation and formation. It has a good preventive effect on tomato, cucumber and tobacco virus diseases. [0003] Brassinolides are one of the steroidal compounds with high biological activity. They are widely present in plants, and they can not only promote vegetative growth, but also facilitate fertilization...
