The autumn tube in the peach orchard where peach trees are planted can increase production in the coming year.

The period from fruit picking to defoliation is the key period of nutrition accumulation and flower bud differentiation of peach trees. The quality of management directly affects the ability of overwintering cold prevention of peach trees and the growth and fruit of the second year. Therefore, fruit growers should pay attention to the management of peach trees after fruit harvest.

Fertilization should be applied early after fruit harvest in early and mid-maturity, especially in trees with too much fruit, and before fruit harvest in late-ripening varieties. The types of fertilization are high-quality organic fertilizer mixed with appropriate amount of nitrogen, phosphorus, potassium compound fertilizer and micro-fertilizer. Water should be irrigated in time in case of autumn drought. In addition, it can also be combined with spraying for extra-root topdressing to supplement nutrition.

Spraying is to protect the leaves and make them have strong photosynthesis, which is beneficial to the accumulation of nutrients. After fruit harvest, emphasis should be placed on the control of diseases and insect pests such as peach leaf perforation, peach aphid, red spider and leaf moth. The available agents are 50% carbendazim 800 times, plus 40% dimethoate EC 1500 times.

Pruning removes the cross branches, overlapping branches, disease and insect branches, thin and weak branches in the crown. The method of short pruning is often used. Generally speaking, the medium-growing long fruit branches are properly truncated to let them bear fruit, and the new shoots near the backbone branches are heavily truncated to produce new fruiting branches. At the same time, the branch group retracted to promote the lower single bud to produce strong branches.

After ploughing and picking fruit, loosen the soil and weed in time, with a depth of 10ml 15cm. Clear the garden after defoliation, and bury weeds and fallen leaves deep under the tree after spraying to control diseases and insect pests. In flat land, low-lying land and peach orchards with heavy soil or weeds, more attention should be paid to regulating the drainage system before the rainy season, lowering the groundwater level, removing weeds and avoiding stagnant water as far as possible.
