Try to choose the leeward area with small slope, and the garden soil should have good air permeability, sufficient organic matter and perfect drainage function to ensure the good growth of wampee.
Seedling colonization
Choose strong seedlings with trunk diameter of more than 0.6 cm and height of 25 ~ 35 cm, which are upright and not bent, with developed roots and good joint healing, and plant them in spring and autumn.
Before planting, it is necessary to dig holes for weathering treatment, and the hole size of each plant should be controlled at 100cm× 100cm×80cm. After weathering for a period of time, apply fertilizer to the soil in the tree hole to ensure that the seedlings can grow sturdily after planting, and the row spacing should be controlled at 4.0m×3.5m.
Prune the seedlings when planting, pay attention to keep the roots stretched, and water the roots after planting or spray the roots of sea elf biostimulant.
Young tree management
Timely fertilization: Fertilization should be started after the germination of new buds, with thin application and diligent application, with nitrogen fertilizer as the main fertilizer, and phosphorus fertilizer, potassium fertilizer and magnesium fertilizer combined with spraying sea elf biostimulant. Fertilize 1 time before each shoot and in the green stage of shoot development to promote hair growth and make new shoots strong.
Water management: wampee will be in a good growth state under wet conditions, so it is necessary to strengthen water management to ensure sufficient water supply and stable growth of wampee, but it is not suitable for waterlogging to avoid damaging the root system.
Tree body management: Core-picking or stem-cutting at the height of 40-50 cm will promote the bud germination under the node and keep 3-4 main branches, so as to keep the secondary main branches and tertiary branches and lay the foundation for production.
Result tree management
Fertilization management: apply flower-promoting fertilizer before and after severe cold, mainly organic fertilizer, supplemented by quick-acting fertilizer, and apply it in furrow; Fertilize before fruit thinning to strengthen fruit and promote summer shoots, mainly nitrogen and potassium fertilizers; Applying autumn bud-promoting fertilizer after fruit picking is helpful to restore tree vigor, promote flower bud differentiation and pay attention to the supplement of phosphorus and zinc. In addition, foliar topdressing should be combined in the flower and fruit period, and foliar sea elf biostimulant can be sprayed.
Water management: wampee root system is shallow, oxygen-loving, neither drought-tolerant, nor poor ventilation and water accumulation in the garden. Pay attention to drainage in rainy season. After the fruit is harvested, irrigation should be paid attention to during the germination period of autumn shoots.
Pruning: After the fruit is picked, two branches should be left at the base of the fruit branches for pruning, so as to promote the strong autumn shoots and cultivate good fruiting mother branches. As a result, when the mother branch picked the fruit, there were no leaf shears, only all the ear parts were cut. After the fruit is picked, the dead branches, pests and diseases branches and too dense shade branches are mainly cut off, and the long branches are shortened to form a ventilated and light-transmitting umbrella crown.
Flower and fruit management: promoting autumn shoots to cultivate fruiting mother branches; When flowering, thin the side ear with poor development at the base of the flower ear, keep the middle 2-3 side ears and cut them short; Spraying gibberellin+leaf-shaped sea elf biostimulant in full bloom to improve fruit setting rate and protect fruit; Fruit thinning will be carried out in late May.
control of insect
The main diseases are canker, soot, anthracnose, root-knot nematode and so on. Pests include psyllid, white moth wax cicada, liriomyza sativae, aphids, scale insects and so on.
