How to Manage Peach Trees After Fruit Harvest? Detailed Explanation of the Latest Technical Points
Peach trees are distributed throughout China, and peaches are also a very popular fruit. When managing peach tree cultivation, we must reasonably adjust the management methods according to the different growth stages of the peach tree. Especially after the peach tree harvests its fruit, the management work is also very important. So how should peach trees be managed after fruit harvest? Today the editor will give you a brief introduction. Let's take a look together below!
1. Soil, Fertilizer and Water Management
After the peach tree harvests its fruit, we should promptly apply a topdressing of quick-acting chemical fertilizer. However, be careful to control the amount of nitrogen fertilizer to avoid excessive nitrogen application causing excessive vegetative growth of peach branches and leaves, thereby affecting flower bud differentiation of the peach tree. For young trees that have just started bearing fruit, each tree needs about 0.5 jin of urea, while for mature trees this can be increased to about 1 jin. At the same time, foliar fertilizer should be sprayed appropriately in combination with pest and disease control work. In September and October, the soil should be deeply plowed, and fully decomposed farmyard manure should be applied along with it. Then winter irrigation should be done well to ensure the peach trees overwinter safely.
2. Timely Winter Pruning
Peach trees grow relatively fast, and after harvest, the new shoots of peach trees grow even faster, easily forming secondary shoots. This easily leads to reduced ventilation inside the canopy of the peach tree, consumes excessive nutrients, and thereby affects flower bud differentiation of the peach tree. Therefore, branches that are too dense, too long, drooping, as well as pest-damaged and upright branches, should be pruned in a timely manner. Thin and weak branches should be appropriately thinned out to avoid consuming excessive nutrients and to improve ventilation and the light environment within the canopy. At the same time, for branches with small angles, branch bending should be done well to open up the angles. Then attention should also be paid to basic pruning work such as heading back, short cutting, shoot twisting and pinching. This improves the ventilation of the tree body, enhances photosynthetic capacity, and promotes the formation of good flower buds.
3. Pest Control
After peach trees are harvested, if pesticide management is neglected, then peach trees are very prone to harm from various pests, such as red spiders and aphids. These pests suck the nutrients of the peach tree, causing reduced nutrient return in the peach tree body and seriously affecting the quality of flower buds the following year. Moreover, if not controlled in time, they will also lay a large number of eggs, which is very unfavorable for the growth of peach trees. Therefore, after the peach tree harvests its fruit, pesticides should be sprayed regularly to control pests, and an appropriate amount of foliar fertilizer and growth regulators can be added. Available agents include brassinolide, potassium dihydrogen phosphate, etc.
4. Orchard Cleaning Work
Orchard cleaning work after the peach tree harvests its fruit is naturally also indispensable. In particular, attention should be paid to doing a good job of land preparation and fertilization, as winter fertilizer is the key to ensuring the peach trees overwinter safely. Land preparation is mainly to clean the peach orchard soil, disinfect the soil, and eliminate bacteria and insect eggs hidden in the soil. At the same time, fallen branches and fruits, residual branches and fallen leaves, and weeds in the peach orchard should be gathered and removed from the orchard and burned. This is because these places easily harbor large amounts of bacteria that overwinter, and in the second year they are also very prone to causing disease, affecting the normal growth of peach trees.
The above is a brief introduction to how to manage peach trees after fruit harvest. That is all for today's introduction. This article is for reference only, and we hope it can be helpful to everyone!
