AI Technical Summary

Technical Problem

Existing technologies are insufficient to efficiently promote the survival rate of transplanted Chinese scholar trees. Traditional leaf removal methods are time-consuming and labor-intensive, chemical defoliants are ineffective against woody plants, and there is a lack of specialized formulas for Chinese scholar trees.

Method used

A defoliant suitable for transplanting Sophora japonica is provided, consisting of component A and component B. Component A contains ethephon, Silwet L-77 organosilicon, citrus peel oil, and mineral oil, while component B contains thiamethoxam, diquat, and specific adjuvants. It promotes leaf senescence and abscission through two-stage spraying. Combined with the synergistic effect of Break-Thru S240 organosilicon, citrus peel oil, quercetin, and sophoridine, it enhances permeability and protective properties.

Benefits of technology

It achieves efficient chemical leaf removal, reduces labor requirements, lowers costs, preserves the tree canopy structure, improves transplant survival rate, and reduces the impact of pests and diseases.

Abstract

The application relates to the technical field of defoliating agents, and particularly discloses a transplant defoliating agent suitable for national locust trees and a preparation method and application thereof. The defoliating agent provided by the application comprises A component and B component; the A component comprises the following components in an amount by weight: ethephon 3-7 g / L, Silwet L-77 organosilicon 0.1-0.5 g / L, green orange oil 0.02-0.08 g / L and mineral oil 0.1-0.5 g / L; water is used as a solvent; the B component comprises the following components in an amount by weight: thiabendazole 3-7 g / L, endothall 5-8 g / L and an additive 0.6-1.2 g / L; water is used as a solvent; and the additive is composed of Break-Thru S240 organosilicon, green orange oil, quercetin and sophoramine in a weight ratio of 8-12:2-6:1-3:0.5-3. The defoliating agent can be used for directional regional defoliation of national locust trees, and has the advantages of low comprehensive cost, simple use method and high defoliation efficiency.
