Detailed Explanation of the Key Points of Wampee Cultivation and Management Techniques
Wampee is a fruit unique to the Lingnan region. It is rich in nutrients and not only has high edible value but can also be used as medicine, with effects of aiding digestion and resolving phlegm, and can treat conditions such as indigestion with food stagnation and phlegm-fluid cough and asthma. The cultivation and management of wampee affects its yield and quality, so how should it be managed during production? Let's take a look together.
1. Management of Young Trees
The root system of young trees is not well developed, is relatively shallow in distribution, and has weak absorption, so the fertilization principle for young trees is frequent application in small amounts, with nitrogen fertilizer as the main type, combined with phosphorus and potassium fertilizers and trace elements. Start fertilizing one month after planting to promote seedling growth, and watering should also pay attention to changes in soil moisture. Young trees grow vigorously and have a relatively high water requirement, but too much water can also damage the root system, so water timely during drought and drain promptly after rain. After young trees are topped, timely pinching should be carried out to promote more branching, accelerate the formation of the canopy, and lay the foundation for future high yield.
2. Management of Fruiting Trees
When clearing the orchard in winter, the fruit trees should be pruned, removing dead branches, diseased and pest-infested branches, shaded branches, and weak branches, which increases the permeability of the tree canopy, reduces unnecessary nutrient consumption, eliminates sources of pests and diseases, reduces the harm of pests and diseases in the following year, and promotes bud differentiation. At the same time, fertilization work should be done well. Fertilization should be carried out both before and after fruiting, and timely topdressing should also be done during the development of autumn shoots, which can promote the timely and robust sprouting of fruiting mother branches and enable them to bear more fruit.
3. Flower and Fruit Thinning
The flower panicles of wampee are relatively large, with a large number of flowers and a long flowering period, but the fruit-setting rate is low. Because the flowering period is long, fruit drop is very likely to occur, and it also affects the growth and ripening of the fruit. Therefore, in order to reduce the consumption of plant nutrients and make the flower panicles mature more uniformly, appropriate flower thinning can be carried out. From flowering to before full bloom, cut off half or one third of the top flower panicles. The same applies to fruit thinning. After fruit thinning, the weight of individual fruits can be increased, making the fruit grow uniformly and ripen consistently. Fruit thinning should be done promptly after physiological fruit drop, generally removing deformed fruits, diseased and pest-damaged fruits, and small fruits.
4. Pest and Disease Control
The main diseases of wampee are anthracnose and sooty mold, and the main pests are white moths and lanternflies. Anthracnose can occur at all growth stages of wampee. The control methods are: strengthen fertilizer and water management to improve tree vigor and the plant's disease resistance; do a good job of orchard cleaning in winter, timely prune diseased branches and leaves, rotten fruits, etc., to reduce sources of disease; and spray pesticides promptly when the disease occurs, such as thiophanate-methyl, Tuzet, chlorothalonil, carbendazim, etc. To control sooty mold, first do a good job of controlling aphids and scale insects, reduce pest sources, and cut off transmission routes. When the disease occurs, spray sulfur suspension concentrate or copper oxychloride suspension for control. For pests, pesticides such as dichlorvos, dimethoate, and methomyl can be sprayed for control, and the main pesticides should be used alternately to avoid developing pesticide resistance.
