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 prior defoliant single agent mainly comprises thidiazuron, defoliant, diuron, glyphosate, pyraflufen-ethyl 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.

L-lysine, chemical name: l-2, 6-diaminohexanoic acid, which is an essential amino acid for human body, has been reported to have an effect of accelerating the abscission of leaves by L-lysine (fanzhen, a new development of amino acid pesticides [ J ] amino acids and biological resources, 1992, (3): 14-16.).
