Embodiment 1

[0029] Grind 8-hydroxyquinoline, potassium chlorate, and magnesium chlorate into 100-mesh fine powder respectively.

[0030] Take 75Kg of 40% ethephon and add it to the stainless steel batching tank, add 6Kg of 8-hydroxyquinoline, 12Kg of potassium chlorate, 6Kg of magnesium chlorate and 1Kg of 95% water-soluble azone in sequence, and continue stirring for 20 minutes to ensure uniform mixing to obtain a slurry product .

[0031] When in use, take 60g of the product and put it into a knapsack sprayer that has added 10Kg of water in advance, stir vigorously to make it fully dissolve. The spraying method is the same as that of commonly used defoliants.

Embodiment 2

[0033] 8-Hydroxyquinoline, potassium chlorate, and magnesium chlorate were respectively pulverized into 80-mesh fine powder.

[0034] Get 72Kg40% ethephon and add in the stainless steel batching tank, add 8Kg8-hydroxyquinoline, 10Kg potassium chlorate, 4Kg magnesium chlorate and 1Kg organosilicon surfactant L-77 successively, after adding the materials, continue to stir for 20 minutes to ensure that the mixture is uniform and obtains Paste product.

Abstract

The invention relates to a physiological time-released type cotton defoliating agent, which consists of the following chemical substances of 40 percent of ethephon, 8-hydroxy quinoline, chlorate, hypertonic speader and the like. The effect of the cotton defoliating agent of the invention is more moderate and lower, thus being beneficial to post-maturation and blooming of the late boll, more particularly, the autumn boll still blooms after frost. The cotton defoliating agent of the invention not only has the function of physiological defoliation, but also has adjustment function of adjusting the openness of stoma of the surface of leaves, can prolong the function period of the leaves and is a novel cotton defoliating agent with both functions of anti-bacterium and sterilization.

Description

technical field [0001] The invention belongs to plant growth regulators, in particular to a crop defoliant, in particular to a cotton defoliant used before cotton is harvested. Background technique [0002] Defoliants have been used on cotton for over 30 years. The use of cotton defoliants can speed up the cracking of cotton bolls, increase the maturity, and eliminate the influence of leaves on boll opening. Especially in areas with rainy autumn, the use of defoliants can facilitate ventilation and reduce cotton boll rot and disease occurrence caused by rainy weather. [0003] Chemical defoliation of cotton is an indispensable and important technical measure for mechanized cotton picking and manual cotton picking. Impurity rate and pollution of cotton leaves to seed cotton. [0004] At present, the commonly used cotton defoliants mainly include ethephon, sheathing treasure, defoliation urea, paraquat (also known as Kewuzong) and MAGSOL, etc. These defoliants have certain ...
