Embodiment 1

[0018] A plant growth regulator composition and application containing brassinolide and metazachlor, which consists of the following components in parts by weight: 0.01 part of 28-homobrassinolide and 1.99 parts of metazachlor.

[0019] The method for preparing the above-mentioned compound growth regulator is to mix the raw materials in the weight ratio evenly, and formulate the microemulsion with 2% active ingredient mass percentage with the adjuvants allowed on the pesticide according to the conventional preparation method.

Embodiment 2

[0021] A plant growth regulator composition and application containing brassinolide and metazachlor, consisting of the following components by weight: 0.0075 parts of 24-epibrassinolide, 0.25 parts of metazachlor

[0022] The method for preparing the above-mentioned compound growth regulator is to mix the raw materials in the weight ratio evenly, and prepare an oil suspension concentrate with an active ingredient mass percentage of 7.5% with the adjuvant allowed on the pesticide according to the conventional preparation method .

Embodiment 3

[0024] A plant growth regulator composition and application containing brassinolide and metazachlor, which consists of the following components in parts by weight: 0.005 parts of propionyl brassinolide and 1 part of metazachlor.

[0025] The method for preparing the above-mentioned compound growth regulator is to mix the raw materials in the weight ratio evenly, and prepare a wettable powder with an active ingredient mass percentage of 4.5% with the adjuvant allowed on the pesticide according to the conventional preparation method .

Abstract

The invention discloses a plant growth regulator composition containing brassinolide and metazachlor and its application. It consists of the following components in parts by weight: 0.001 to 1 part of brassinolide, 0.1 to 1 part of metazachlor 2 servings. The invention can promote the effective regulation of cotton defoliation, promote cotton cracking and boll opening, accelerate cotton leaf shedding, reduce impurities, improve harvesting rate, and improve cotton grade and quality.

Description

technical field [0001] The invention relates to the technical field of agricultural growth regulators, in particular to a plant growth regulator composition containing brassinolide and metazafen and its application. Background technique [0002] Cotton is the seed fiber of the Malvaceae (Malvaceae) plant of the genus Gossypium, native to the subtropical zone. Annual woody, 0.6-1.5 meters high, branchlets sparsely covered with long hairs, leaves broadly ovate, flowers solitary in leaf axils, pedicels usually slightly shorter than petioles; calyx cup-shaped, flowers white or light yellow, later turning light red or purple . [0003] With the continuous increase of cotton planting area, cotton mechanical harvesting has become the current development trend, but the leaves left on the cotton plants not only affect the harvesting speed, but also affect the grade of cotton. Therefore, timely ripening and defoliation of cotton is of great significance to cotton quality, high yield...
