Chemical control method for improving lodging-resistance capability and yield of flax through uniconazole

Abstract

The invention discloses a chemical control method for improving the lodging-resistance capability and yield of flax through uniconazole. The method comprises the step of growth vigor assessment, wherein the growth vigor of the flax in the rapid growing period is comprehensively assessed; the step of pesticide preparation, wherein the uniconazole is dissolved through anhydrous alcohol, and then concentration water adding preparation is carried out; the step of application period selection in the budding period of the flax, wherein when the flax plant is in the budding period, the optimal application period is selected; the step of pesticide applying, in the sunny windless morning or afternoon, a sprayer is used for evenly spraying the uniconazole. Compared with an lodging-resistance breeding method, the method has the advantages that the height of the flax can be quickly reduced, branches of the flax can be shortened, the group structure is improved, the stem diameter and the root diameter of the flax are increased, the lodging-resistance capability is enhanced, and the yield increasing effect is remarkable; after 100 mg/kg uniconazole is applied in the squaring period, the effects of shortening the flax plant and increasing the stem diameter, the fruiting number of the single plant, the thousand seed weight and the yield are remarkable, and the yield of the flax is increased by 27.83% compared with that of a comparison set.

Description

technical field [0001] The invention belongs to the technical field of crop chemical control, and in particular relates to a chemical control method for improving flax lodging resistance and yield by using uniconazole. Background technique [0002] Chemical regulation technology is a cultivation technology that uses a series of plant growth regulators (PGR) to regulate the growth and development of crops. The chemical regulation of PGR on the growth and development of crops works in three ways: changing the endogenous hormone system, or interacting with endogenous hormones, and regulating endogenous hormones. In this system, the application of chemical regulators has two most important functions: one is to modify the traits of crops, such as changing tall stalks to short stalks, changing late maturity to early maturity, and maximizing the potential of improved varieties; The second is to change the normal growth pattern of crops under adversity, such as dense planting and l...
