Key points for the management of peach orchards in spring by pruning young trees into trees and grasping water and fertilizer

Spring peach orchard management, young trees to grasp pruning shape, hanging fruit trees to catch water and fertilizer and pest control, in order to ensure high and high yield of peach.

Peach tree pruning

Pruning young trees to make crowns:

The seedlings of peach trees should be reshaped in spring, and most of them are naturally happy in the shape of three main branches. generally, they are truncated at the 50cm from the ground after setting the value. Note that there should be 8 full buds under the shearing mouth. After sprouting in spring, 3-4 branches with strong growth and different directions should be selected to grow into the main branches. The landing point of the main branch should have a certain distance, and the strength can be controlled by changing the angle. For the rest of the branches, those competing with the main branches should be removed and the weak ones should be retained as auxiliary branches.

From May to June, the main branches grow healthily, and the main branches up to 60-80cm can pick the heart, promote secondary shoots, cultivate secondary main branches and secondary main branches, and expand the crown. The cutting buds are generally left on the outside, and the lateral branches germinating below choose a suitable and robust branch as the secondary main branch. The secondary main branches left by each main branch should be on the same side to avoid emptiness or collision. In this way, the second main branch can be cultivated in one year, and the second branch can be left in the second time to form a tree crown, which can be put into production in the third year.

Fertilizing and interplanting mature soil:

For the newly developed peach orchard, it is necessary to expand the scope of soil improvement, dig a round trench or trench about 40cm at the original hole or trench, and apply organic fertilizer to improve the soil. In addition, quick-acting fertilizers such as urea can be applied before each growing season to promote branch growth. The gap in the young tree orchard can interplant all kinds of crops, increase income, bury or cover rice stalks as fertilizer, use legumes or legumes mixed with Gramineae crops, cultivate soil fertility and serve as fodder, and slope protection grasses can also be planted on the ladder walls, preferably with green crops to cover the ground.

Clean up stagnant water:

Peach trees are afraid of stagnant water, so they must be well drained in the rainy season. If the back trench is clogged, clean up the circulation and cultivate the silt on the tree plate. The tree plate can be covered with loose soil in the dry season to reduce water evaporation.

Topdressing fruit trees before blooming:

Peach trees have entered the period of sprouting, flowering, fruit setting and new shoot growth from March to April. in order to meet the nutrient needs of new shoot growth and young fruit development of peach trees, topdressing before flowering is important, especially for fruit trees with weak growth or peach orchards with excessive yield last year. Nitrogen fertilizer can be applied appropriately before flowering to promote fruit setting and tree growth, but attention should be paid to the amount so as not to cause new shoots to flourish and aggravate fruit drop.

1-3-year-old young trees apply 150-200g urea per tree, while adult trees with weak body generally apply 300g-500g urea per tree. The fertiliser can not be applied to the fruiting trees with strong growth. For adult trees entering the peak period, little or no nitrogen fertilizer should be applied in spring. Waterlogging and drought are most feared during flowering and young fruit. Stagnant water in orchard will not only affect the absorptive capacity of roots, but also affect the necrosis of new roots, resulting in falling flowers and fruits. Therefore, Pingdi Taoyuan should dredge the ditch in time, clean up the silt and fill the gap. In case of drought, to fight drought in time, we can take the form of ditching and diverting water to moisten the chamber surface or sprinkler irrigation. At the same time, the available fertilizer was mixed into the water and applied with the water.

Pest control:

Peach trees are vulnerable to diseases and pests such as anthracnose and aphids in spring. In order to prevent peach trees from early diseases and insect pests, before peach flower buds and leaf buds protrude the epidermis, the crown should be sprayed with a new high-fat film, and the tree body should be smeared with tree protection generals to prevent the invasion of diseases and insect pests. Once aphids are found, 10% imidacloprid 2000 times can be used; anthracnose can be controlled with 80% anthrax Fumei 500 times; brown rot can be controlled with 70% Dysen zinc 500 times or 50% Sukeling 1000-1500 times, glue disease can be scraped off with broken porcelain tiles and painted with 30 times liquid bacteriophage.
