During the growth period of wampee, attention should be paid to shaping, pruning and cultivating branches to promote the robust growth of trees, and topdressing to manage water. In case of high temperature and drought, attention should be paid to water conservation and drought prevention. Pay attention to drainage in rainy season, control the reproductive growth of trees, promote vegetative growth, and prepare for the flowering and fruiting of fruit trees. Attention should be paid to flower protection after flowering of wampee, and the management of fertilizer and water in the whole process of flower protection should be strengthened to improve the quality of flowers. The growth trend of vertical and horizontal diameter of wampee fruit is double "S" shape. In the process of fruit growth, corresponding technical measures should be taken to prevent fruit falling and improve fruit yield. At the same time, we should make corresponding artificial fruits and vegetables to improve fruit quality.
It takes 70~80 days for wampee to mature. When the fruit is ripe, it should be harvested in time, neither too early nor too late. Note that it is not advisable to spray water or water or spray pesticides within a few days before harvesting, and the harvesting process should be handled with care to avoid damage.
Planting techniques of wampee
1, planting time: spring is the best. Spring sowing is usually carried out in March-May, when there is more rain, the temperature rises, it is easy to take root and the survival rate is high. When transplanting, the root system of nutrient bag seedlings is less affected, and the garden with irrigation conditions can be planted in spring, summer, autumn and winter.
2. Planting density: generally, 50-80 plants are planted per mu, mostly in the form of wide rows and narrow plants. The plant spacing can be 3m× 4m or 2.5m× 3.5m When planning close planting, about 1 10 plants are planted per mu, and the plant spacing can be 2m× 3m.
3. Seedling raising: select excellent varieties suitable for local cultivation. Seedlings should be short and dry, with lush foliage and no pests and diseases.
4. Preparation of planting holes: after the planting position is determined according to the plant spacing, holes are dug according to the specifications of length, width and depth of 65, 438+0m and 0.8m respectively, soil miscellaneous fertilizers are applied in layers and returned to the soil, and the last layer is returned to the soil. Each hole is buried with 50 kg of green manure+50 kg of soil miscellaneous fertilizer+0.5 kg of lime+0.5 kg of phosphate fertilizer, and the planting hole after ploughing is about 20 cm higher than the ground. When planting in a flat orchard with high groundwater level, the planting holes are layered with decomposed compost and in-situ soil or exotic soil to form a mound with a pier height of about 30 cm and a bottom width of1m.
5. Planting: When planting, the roots of wampee seedlings should avoid contact with fertilizers, the seedlings should stand upright, and the roots should naturally extend around. The planting depth should be covered with fine soil to the root neck and maintained at the same depth as the seedling stage. Be careful when planting, and compact the fine soil gently. After planting, water the roots, and cover the trees with grass to keep them moist to prevent sun and rain.
