How to improve the fruit set rate of apricot trees? An introduction to practical methods
How to improve the fruit set rate of apricot trees? What methods can improve the fruit set rate? Please introduce: To improve the fruit set rate of apricot trees, the following methods can be used: pruning: lightly prune vigorous trees in winter, and appropriately thin or shorten branches or buds on weak trees to reduce nutrient consumption. For main branches, cut off 1/3 of the current year's growth to keep the main branches balanced. Shorten water sprouts, competing branches, and drooping branches; retain development branches and keep more small branches unpruned; for water sprouts in the canopy, cut 1/2~1/3 of the current year's new shoots so that strong shoots grow at the top and fruit branches form on the lower part; for thin and weak branches inside the canopy, cut from 4~5 buds outside the base; for aged and overlong fruit branches, renew large branches by retrenchment and shorten medium and small branches; after the extension shoots of main and lateral branches reach the standard, pinch off the top 3~4 nodes.
