How to manage peach trees after picking? A full breakdown of the latest management points
At this time it is already the season when peaches ripen and hit the market. As peaches come onto the market one after another, management after picking is also quite important, as it determines the disease situation and yield level next year, so management at this time must be taken seriously. So how should peaches be managed after picking? Let's learn about it together.
1. Pruning and care
At this time the pruning principle is to cut small branches, not large branches; cut current-year branches, and it is not advisable to cut current-year branches; pruning time should be early rather than late; pruning degree should be light rather than heavy; the principle of reducing yield a small amount multiple times. For upright vigorous branches on the back that seriously affect light, cut them off 15 cm up from the base, as long as they do not affect the light of the lower fruiting branches; if cut off from the base, excessive rain in autumn can easily cause excessive vegetative growth. In addition, the pruning principle only needs to achieve good aeration and light penetration, and it should not be pruned too heavily, so as to avoid fruiting branches sprouting autumn shoots.
2. Root irrigation and topdressing
After fruit picking, fertilize in combination with weeding. For plants with a large number of fruits and low nutrient consumption, apply early and heavily, and dig a ring-shaped trench around the outer edge of the canopy, with a depth of 40-50 cm being suitable. Apply microbial organic fertilizer. If there is little rain and it is relatively dry, it can be paired with humic acid water-soluble fertilizer to supplement comprehensive nutrition for the tree, and at the same time it can also activate and improve the soil, increase the utilization rate of organic matter, and improve the immunity and stress resistance of peach trees. For root rot and weak tree vigor, when fertilizing you can irrigate the roots with metalaxyl and hymexazol to kill the pathogen and promote wound healing.
3. Spraying and brushing trunks
Before leaf fall, you can spray the foliar fertilizer potassium dihydrogen phosphate solution, applying it once every 15-20 days. After fruit picking and before leaf fall is the period when the plant stores nutrients. Spraying potassium dihydrogen phosphate at this time can increase leaf chlorophyll content, promote the plant's photosynthetic efficiency, synthesize more nutrients, increase chlorophyll content, and prevent various diseases such as peach shot hole disease and brown spot disease. For those that have previously had gummosis, grafted parts, wounds on branches and trunks, or weak growth, before leaf fall in autumn you can apply carbendazim or lime sulfur mixture to the branches and trunks to promote wound healing and also enhance cold resistance.
