Pear Tree Management Plan in May

Now it is May, which can be said to be the beginning of midsummer. Summer is a critical period for the growth of pear trees, and its climatic characteristics have a significant impact on the development of the branches, leaves, fruits and roots of pear trees. Pear orchard management requires special attention during this season. Learn about the management plan for May pear trees below.

1. Plastic surgery

For new shoots with sufficient growth space, pinch them when they reach about 20 cm in length to promote the formation of fruiting branches. For pear trees with strong growth potential, retain an appropriate amount of leggy branches, and improve light conditions and promote flower bud formation through measures such as twisting and pulling branches. In mid-to-late May, ring-cut the main, side branches or supporting branches of young trees to promote flower bud differentiation. Before the new shoots become lignified, use toothpicks to prop up the base angle of the fruiting branches to about 80°, strengthen fertilizer and water management, and promote flower bud formation and early fruiting.

2. Fertilizer and water management

From late May to early June, before flower bud differentiation, apply special fertilizers for fruit trees with phosphorus and potassium as the main components and nitrogen as the supplement, depending on the age of the trees and the amount of fruit produced, and irrigate in time. Combined with disease and pest control, urea or potassium dihydrogen phosphate should be sprayed regularly to meet the fruit's needs for water and nutrients.

3. Orchard management

As the temperature rises, loosen the soil and weed in time to maintain soil moisture and prevent excessive weed growth. Orchards with the necessary conditions can carry out orchard mulching, using wheat straw to cover the spaces between fruit tree rows or in tree trays to improve the soil environment.

4. Fruit bagging

Bagging can effectively improve the appearance quality of fruits, reduce pests and diseases and pesticide residues, and improve fruit safety and market competitiveness. Bagging should be completed within 25 to 45 days after flower fall, and insecticides and disease control agents should be sprayed 5 to 7 days before bagging.

5. Pest and disease control

During the young fruit stage, the focus is on preventing and controlling rust, black spot, ring rot and pear psyllid , etc., by manually removing diseased and insect-infested shoots and spraying pesticides such as mancozeb and carbendazim. During the long shoot growth period, use Dasheng M-45, Xinwansheng, Subaoli and other agents to prevent and control black spot disease, black spot disease, pear rust, as well as pests such as pear psyllids and aphids. During the fruit expansion and ripening period, continue to prevent and control black spot disease, ring rot, rust and fruit borer, using Bordeaux mixture and pyrethroid pesticides for prevention and control.

In short, through comprehensive management, we can ensure the healthy growth of pear trees during the critical growing period of summer, laying a solid foundation for improving fruit quality and yield.
