Huangpi fruit is rich in nutrition and can promote digestion and strengthen the spleen and stomach. It is also a characteristic fruit of Hainan. The fruit of wampee contains vitamin C, organic matter, sugar, gum Arabic and so on. Its flavor is unique, with sweet, sweet and sour taste. Planting wampee is an ideal project to get rich, which is suitable for planting in hilly and mountainous areas with low risk and less capital investment.
Planting techniques of wampee 1. Selection and creation of wampee in China gardens 8. Wampee can be planted in rivers, farmland, sandy soil, and sticky soil behind the front room of the house, and it likes wet and warm natural environment. There are not too many regulations, but it is best to plant it in sandy soil with loose texture, rich layers and good drainage pipes.
Second, the types of yellow skin selection are seedless yellow skin, chicken heart yellow skin, old rock sugar yellow skin and so on. Among them, seedless wampee is most warmly welcomed by us, and seedlings about 60cm high are used for grafting.
Thirdly, the management method of liquid fertilizer is the key to the super-high yield technical process. For young wampee trees transplanted for 1-3 years, because the roots are not fully developed and the absorption capacity is weak, dilute and available potassium and base fertilizer should be added once a month to make them appear several times a year, so as to quickly expand the crown, improve the leaf area index, lay a good foundation for early fruiting and good harvest, and promote growth. Generally speaking, for fruit trees, fertilization should be carried out three times a year. The first time is from mid-late October of/kloc-0 to mid-early February of 65438+. In order to promote the growth of spring shoots, improve the fruit setting rate and reduce the loss of flowers and fruits,
Apply 0.2-0.3 kg of NPK quick-acting compound fertilizer before spring shoots germinate; May is usually the second time. In order to promote the growth of summer shoots, expand small fruits, and improve the quality and benefit of fruits, strong fruit fertilizer was applied before the summer shoots sprouted, and the combination of nitrogen and potassium was 0. 15-0.2kg, and vitamins should be supplemented immediately after picking. At this time, the fertilizer demand is 50% of the annual fertilization. Organic fertilizer is the dominant fertilizer, and compound fertilizer can also be increased. Adult wampee orchards should always keep the soil loose, avoid washing the soil, and do a good job of subsoiling and change it to *.
Cultivation techniques of Huangpi 4. The function of plastic and cosmetic pruning of young trees is to shape the technical backbone branches, balance the plant type, adjust the growth of branches, make them produce a certain number of main branches and branches, form a tenacious crown framework, and lay a good foundation for early harvest. The crown of wampee should be made into a round mouth, and the top should be cut at the height of the main stem of 70-80cm, then 3-4 main branches should be left, and the nutrition should be evenly distributed, and then the side main branches and hair branches should be drawn out to make a round head crown. Fruit tree pruning can be appropriately pruned and moderately thinned.
In the flourishing growth period, the top can be properly picked to weaken the growth potential, stimulate 2-3 lateral buds to germinate under the incision, promote the growth of branches and improve the growth. Every winter, cut off the shady branches, over-dense branches, dead branches, blind branches and insect branches in the crown, improve the light transmittance standard of natural ventilation in the crown, and avoid diseases.
