Enhancing The Stress Resistance of Tea Tree
Regulators that enhance the stress resistance of tea plants
2,4-D
Spraying 200mg/L 2,4-D liquid before the overwintering of tea trees can improve the cold resistance of tea trees and have a significant stimulating effect on the spring shoots of the following year.
6-BA 50mg/L6-BA
6-treatment of "Fuding Dabaicha" tea seedlings, the contents of chlorophyll, soluble sugar and soluble protein, the enzyme activities of SOD, POD and CAT, and the contents of malondialdehyde and proline were all affected to different degrees. Significantly improve the cold resistance of tea trees.
Ethephon
Spraying with 800mg/L liquid in late October can inhibit the re-growth of tea trees in late autumn and enhance the cold resistance.
Butyric hydrazide
Spraying 1000-3000mg/L butyrate hydrazide solution in late September can promote the stagnant growth of tea trees in advance, which is favorable for overwintering, and the spring shoots grow well in the second year.
Chlorhexidine
Spraying 250mg/L chameleon solution in late September can promote the stagnant growth of tea trees in advance, which is conducive to overwintering, and the spring shoots grow well in the second year.
Abscisic acid
Spraying 25mg/L abscisic acid can increase the stomatal diffusion resistance of tea trees and reduce water potential, thereby reducing transpiration water loss and improving drought resistance.
