Cultivation and management techniques of wampee

Yellow bark is a unique fruit in Lingnan region, which is rich in nutrition. It not only has high edible value, but also can be used as medicine. It has the effect of eliminating food and resolving phlegm, and can treat diseases such as food accumulation, phlegm drinking, cough and asthma. The planting management of wampee is related to its yield and quality, so how to manage it during production? Let's take a look.

1. Management of young trees

The root system of young trees is underdeveloped, the distribution is shallow, and the absorption is weak, so the principle of fertilization for young trees is to apply frequently and thinly, mainly nitrogen fertilizer, with phosphorus and potassium fertilizer and trace elements. Fertilizing starts after one month of planting to promote the growth of seedlings, and watering should also pay attention to the change of soil moisture. Young trees grow vigorously and need more water, but too much water will also damage the roots, so it is necessary to water in time during drought and drain water in time after rain. After the young tree is caused, it is necessary to pick the heart in time, promote its multi-branching, speed up the formation of the crown, and lay the foundation for high yield in the future.

2. Result tree management

When clearing the garden in winter, fruit trees should be pruned, such as withered branches, disease and insect branches, shade branches and weak branches, so as to increase the permeability of plant crown, reduce unnecessary nutrient consumption and eliminate the source of diseases and insect pests, reduce the harm of diseases and insect pests in the following year, and promote bud differentiation. At the same time, fertilization should be done well, both before and after fruit, and topdressing should be done in time when the autumn shoot develops, which can promote the germination and sturdiness of the fruiting mother branch and make it bear more fruit.

3. Thinning flowers and fruits

When the flower is yellow, the spike is larger, the number of flowers is large, and the florescence is long, but the fruit setting rate is low. Because of the long flowering period, it is easy to cause fruit drop, and it will also affect the growth and ripening of fruit. Therefore, in order to reduce the nutrient consumption of the plant and make the spike maturity consistent, we can carry out appropriate flower thinning and cut off half or 1/3 of the top spike before flowering to full bloom. The same is true of fruit thinning, fruit thinning can increase the weight of a single fruit, so that the fruit growth is uniform, the ripening period is consistent, fruit thinning in time after physiological fruit drop, generally thinning deformed fruit, disease and insect fruit, small fruit.

4. Pest control

The main diseases of wampee are anthrax and soot, and pests are mainly white moths and wax cicadas. Anthracnose can occur at all growth stages of wampee. The prevention and control methods are as follows: strengthen fertilizer and water management, improve tree potential and plant disease resistance, do a good job of cleaning among gardens in winter, trim off diseased branches and leaves and rotten fruits in time, reduce the source of disease, and spray medicine in time when it occurs, such as topiramate, carbendazim, chlorothalonil, carbendazim and so on. In order to control soot disease, we should first do a good job in the control of aphids and scale insects, reduce the source of insects, cut off the route of transmission, and spray sulfur gel suspension and copper oxychloride suspension to control the disease. Insect pests can be sprayed with dichlorvos, dimethoate, methotrexate and other insecticides, and the main agents are used alternately to avoid drug resistance.
