Peach tree management plan and measures in May

With the arrival of May, the temperature gradually rises, and peach trees enter a critical stage of physiological fruit drop, rapid growth of young fruits, vigorous elongation of new shoots, and peak root growth. At the same time, as the climate warms, the activities of pests and diseases are becoming more frequent. Therefore, field management in May is crucial to ensure the healthy growth of peach trees and the quality of their fruits. Below is a study of peach tree management plans and measures for May.

1. Summer pruning

May is the critical period for the transformation of young peach fruits into hard cores. Summer pruning is mainly carried out in the middle and early months of the year, including pinching, pruning and branch control, with the aim of adjusting the tree shape, balancing the tree vigor and promoting the rational distribution of nutrients. When the new shoots grow to about 20 cm, pinch them off and remove competing branches and overcrowded branches at the same time. The number of pinching should be adjusted appropriately according to the strength of the tree, and care should be taken to protect the wounds to prevent infection by pathogens.

2. Thinning fruits

Fruit thinning is an effective means to improve fruit quality. It ensures balanced distribution of fruit nutrients through reasonable loading and maintains good fruit shape and size. The time for fruit thinning varies depending on the maturity period of the peach tree variety . Early-maturing varieties are mostly harvested in early May, mid-maturing varieties in mid-May, and late-maturing varieties in late May to early June.

3. Topdressing

During the hard-core period, peach trees have an increased demand for fertilizers such as phosphorus, potassium, and calcium. Timely application of hard-core fertilizers can help harden the core, improve the appearance quality and hardness of the fruit, and promote root development.

4. Fruit bagging

Bagging is an important measure to protect fruits and improve their commercial quality, and is especially suitable for mid- and late-maturing varieties. The time for bagging is generally chosen in late May, and the specific time depends on the fruit setting rate and physiological fruit drop of the variety. Before bagging, fruit trees need to be treated for diseases and calcium fertilizers should be sprayed to prevent fruit diseases and fruit cracking. Bagging should be completed within 2 to 3 days after treatment.

5. Pest and disease control

May is the peak period for diseases and insect pests, and the hot and rainy weather conditions easily lead to the spread of diseases and insect pests. Therefore, pest and disease control work must be done through early prevention and early treatment to avoid causing serious losses to the orchard .

As the temperature rises, peach tree management has entered a critical period. Through the above measures, the growth quality of peach trees and the economic value of the fruit can be effectively improved, bringing better benefits to fruit farmers. At the same time, attention should be paid to flexibly adjusting management strategies according to local climatic conditions and the characteristics of peach varieties.
