Citrus Fruits: Currently in the primary pruning season. Pruning characteristics for major varieties are as follows: ① Sweet Orange—Promptly remove thorns; prune to open crown and suppress height; thin outer branches while retaining inner ones; promptly shorten multi-year fruiting branches; retain weak branches on vigorous trees and strong branches on weak trees.② Sweet Pomelo: Remove strong, retain weak branches on upper and outer sections; thin out dense areas. Preserve various short, weak shoots (including leafless spring shoots, lightly prune vigorous summer shoots, and lightly cut moderate summer/autumn shoots) in the interior and lower-middle sections. ③ Wenzhou Mandarin: After fruiting, promptly prune back horizontal and drooping branches to strong new shoots near the base; lightly prune long branches to promote branching.Prioritize retaining weak branches and removing strong ones among adjacent branches. ④ Pomelo: Remove strong branches and retain weak ones on upper parts; remove upright branches and retain slanting ones. On lower and inner parts, remove weak branches and retain strong ones, selecting superior and eliminating inferior ones; retain more small branches on main skeletal branches. Promptly prune back summer and autumn shoot mother branches to prevent them from becoming fishing rod-like.
Pear Orchard
Pear Orchard: From flower bud opening to inflorescence emergence marks the peak period for overwintering pear fruit moth larvae transforming buds into feeding stages, constituting the first critical control window. Beyond removing infested buds (where scales are silk-bound and non-detachable) during pruning where feasible, timely pesticide application is essential. Additionally, conduct artificial pollination during peak flowering.Method: Use hand-pollination with flowers from compatible varieties or gently sway flower clusters. Pollinate each inflorescence with two flowers exhibiting larger ovaries and thicker pedicels.
Peach Orchards
Peach orchards: Implement artificial pollination as described for pear orchards. Auxiliary pollination is particularly crucial for varieties lacking pollen or with styles significantly higher than anthers, as well as under unfavorable weather conditions. Brown rot is a major disease affecting peaches.When peach blossoms begin to fall, it marks a critical window for brown rot control. This opportunity must not be missed. Timely, high-quality, and sufficient pesticide application is essential. Failure to do so will not only impact the current year's yield and fruit quality but also create greater challenges for future disease management.
