The latest key points of peach management after picking

At this time, it is the mature season of peaches on the market, with the peaches on the market one after another, the management of peaches after picking is also more important, which determines the disease situation and yield next year, so we must pay attention to the management at this time. So how to manage the peach picking? Let's get to know it with the editor.

1. Pruning nursing

At this time, the pruning principle is to prune the twigs, not the big ones; to cut the current year's branches, not to cut the same year's branches; to prune early rather than late; to trim light rather than heavy; and to reduce production by a small number of times. For the erect strong branches on the back, seriously affecting the light, cut off from the base to the upper 15 cm, as long as it does not affect the illumination of the lower fruit branches, if cut from the base, too much Rain Water in autumn is easy to cause overgrowth. In addition, the pruning principle only needs to achieve good permeability, not too heavy pruning, so as to avoid the sprouting of autumn shoots.

2. Root irrigation and topdressing

Fertilization combined with weeding after fruit picking should be applied early and re-applied to the plants with a large number of hanging fruits and low nutrient consumption, and the ring ditch should be dug outside the crown with a suitable depth of 40-50 cm. With the application of microbial organic fertilizer, if the weather is less and dry, it can be combined with humic acid to supplement the overall nutrition of the tree, at the same time, it can also activate and improve the soil and improve the utilization rate of organic matter. improve the immunity and stress resistance of peach trees. As for root rot disease and weak tree potential, Metalaxyl can be used to irrigate the root during fertilization to kill the source of the disease and promote wound healing.

3. Spray brush drying

The foliar fertilizer potassium dihydrogen phosphate solution can be sprayed before defoliation, every 15-20 days. After fruit harvest, the plant nutrient reserve period is before falling leaves. At this time, spraying potassium dihydrogen phosphate can promote plant photosynthetic efficiency through leaf chlorophyll content, synthesize more nutrients and increase chlorophyll content to prevent peach perforation, brown spot and other diseases. For those with previous glue, grafting sites, branches with wounds, and weak growth, you can smear the branches with carbendazim or stone-sulfur mixture before falling leaves in autumn to promote wound healing and enhance frost resistance.
