Brief introduction of wampee tree planting
Astragalus membranaceus likes mild and humid environment and is a shade-loving tree species. Suitable for growing in sheltered and slightly shaded places, not resistant to strong light. It is suitable for planting from March to May in spring. Keep the soil moist during the growing period, loosen the soil every year and remove weeds in time.
Huangpi tree is endemic to Guizhou, and few people plant it. Location: Baxi, Wuyunshan and Bai Qing Nature Reserve in Tongzi County, Guiding, Guizhou.
The fruit of Huangpi tree planted for many years.
If the wampee is properly maintained after planting, it will generally bear fruit in about three years. Its origin is in the south of China, such as Guangdong, Guangxi and Fujian. Belonging to tropical and subtropical plants, it requires high temperature, light and humidity. Therefore, to plant wampee, we must ensure that the temperature is appropriate, the light is sufficient, and the humidity is appropriate.
Grafted wampee trees blossom and bear fruit.
Grafted wampee seedlings can blossom and bear fruit in the second year or the year after, and potted wampee trees generally bear fruit in three years.
Why doesn't yellow skin bear fruit?
The main reason why wampee trees do not bear fruit is that the amount of fruit left in that year is too large and the nutrient consumption is too high. Before fruit picking, no fertilizer mainly containing nitrogen, phosphorus and potassium is applied. When the tree does not return to normal, the flower buds are difficult to differentiate, which leads to poor flower quality and difficult fruit setting in the next year.
In addition, in winter, the amount of base fertilizer, mainly organic fertilizer, is not enough, the organic matter accumulated in plants is too small, and the phenomenon of plant size and age is obvious, which will also lead to the poor harvest of wampee trees.
Key points of planting wampee tree
1, growth conditions
Huangpi fruit likes a fertile neutral soil environment rich in organic matter. If planted in loess, it will cause poor growth. Huangpi fruit does not need high temperature. Generally, it can grow normally above 15 degree, and it will not freeze to death even below 0 degree.
2. Variety selection
Any fruit tree has more than a dozen sub-varieties. Take Huangpi as an example. At present, there are many common yellow peels, such as intentional yellow peels, seedless yellow peels, sweet yellow peels and black yellow peels. Among them, black yellow peels are one of the best varieties at present, because they are more resistant to rainy environment than other varieties, that is to say, they will not crack in rainy days, which is one of its advantages.
3. Pest management
Generally speaking, there are few diseases and insect pests in wampee, because there are few diseases and insect pests in wampee, so there is no need to spray medicine. Even if there are pests and diseases, there are some green worms or some whiteflies. If it is serious, you can spray it with cypermethrin slightly.
4. Flowering management
Huangpi trees have extremely long ears and grow vigorously. In order to ensure the balanced growth of nutrition in the fruit, flowers should be thinned when the ear is 20 cm long, because the longer the ear is, the more important thing is that the ripening time of the fruit is uneven. If it is sold, I am afraid no one will take care of it.
5. Picking management
The wampee began to blossom in March and matured in June. The picked branches need to be pruned reasonably, which is beneficial to the growth of new shoots in summer and prepares for high-yield branches in the coming year.
