Description
Technical Field
The invention relates to the technical field of pesticides, and particularly relates to a cotton defoliation ripening composition and a cotton defoliation ripening agent.
Background
Cotton is an important multipurpose economic crop, can be made into fabrics of various specifications, and can also be used for extracting edible oil by a certain process, so that the cotton plays an important role in the agricultural and economic patterns of China.
The cotton has unlimited growth habit, but is influenced by weather conditions, when frost withers come every year, most cotton bolls in most cotton areas in China cannot complete boll opening, a part of cotton bolls cannot mature in late autumn, and a part of cotton bolls become frost flowers, so that the quality of the cotton cannot be guaranteed. At present, mechanical cotton harvesting is a great trend, and in order to ensure the quality of cotton during mechanical harvesting, the cotton needs to be defoliated and ripened timely. The existing defoliant single agent mainly comprises thidiazuron, defoliant phosphorus, diuron, glyphosate and the like, and a defoliant compound preparation mainly comprises thidiazuron and diuron, and can be absorbed by plants to induce the formation of petiole abscission layers, so that the falling of leaves is accelerated. At present, no plant regulator capable of defoliating and accelerating maturity is found, so that a novel efficient defoliating and ripening composition formula is screened out, and the economic value significance is achieved.
Glyphosine is also known as glyphosine, and the chemical name is as follows: n, N-bis (phosphono-methyl) glycine, glyphosine, is the first commercial sugarcane ripener in the United states and is mainly used for sugar-increasing and ripening of sugarcane and beet.
Thidiazuron (TDZ) is also known as defoliation, defoliation urea, Dropp, chemical name: 1-phenyl-3- (1,2,3, -thiadiazol-5-yl) urea. The thidiazuron is used as a defoliant in cotton planting. After being absorbed by plants, the defoliating agent can promote the natural formation of the separated tissues between the petioles and the stems to shed, and is a good defoliating agent.
At present, no report of a cotton defoliation ripening composition consisting of glyphosine and thidiazuron is reported.
