Embodiment 1

[0027] The components and contents of the preparation for delaying the brassinosteroid action period are as follows:

[0028] Brassinolide 10 mg (0.01%)

[0029] 95% alcohol 50ml (49.94%)

[0030] Cyclodextrin 100 mg (0.1%)

[0031] 98% Tween 80 10 mg (0.01%)

[0032] 50ml of water (49.94%)

[0033] Preparation method: Weigh each component according to the above ratio, firstly dissolve brassinosteroids in alcohol, then add cyclodextrin and Tween 80, mix uniformly to form a solution, and then mix the solution with water evenly.

[0034] At the 3-leaf stage of cucumbers in the greenhouse, take 10 ml of this preparation, add 10 liters of water, mix well, and then spray evenly on the surface of cucumber leaves in the morning until moist. Thereafter, use it every 2 weeks until mid-harvest. See Table 1 for the photosynthetic effect compared with the control example (spraying Tianfengsu produced by Jiangmen Pesticide Factory in Guangdong).

Abstract

A chemical for elongating the action time of brassinolide is prepared from brassinolide (0.0012-0.037%), alcohol (9-69%), cyclodextrin (0.0062-0.062%), tween (0.0062-0.062%) and water (29-89%) through sequential mixing. It is applied through diluting with water and spraying it on the leaves of plant. It can increase the yield of plant by 15-30%.

Description

technical field [0001] The invention relates to a plant growth regulator, in particular to a preparation for prolonging the action period of brassinosteroid. Background technique [0002] Brassinolide is a new type of plant growth regulator, which has the effects of improving yield and resistance. However, most of the current brassinosteroid preparations have the problem of short action period, and they need frequent spraying to show good effects, which increases manpower and cost, thus hindering the promotion and application of brassinosteroids in agriculture. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a preparation that can effectively prolong the action period of brassinosteroids. [0004] The technical solution adopted in the present invention is a preparation for delaying the action period of brassinosteroid, the composition and content of which are as follows: [0005] Brassinoli...
