Planting pomelo like warm, wet, need fertilizer, require deep fertile soil, pomelo tree should pay special attention to planted in the soil after the fertilizer is relatively rich, adequate soil moisture or water conditions are good places.

Fertilization. The sapling trees are small, with young roots, and they should be applied thinly. Before and after fruit harvesting, their fertilization accounts for half of the annual fertilization, and a large amount of delayed fertilizers such as green manure, compost, manure, and cake fertilizer should be applied. In combination with plant electronic fertilizer, the use of high-energy electrons emitted from the photosynthesis of the plant itself and the principle of polarity induction of plant electrons improve cell division, molecular synthesis, and nutrient-matched digestion levels, accelerate the metabolism frequency, and activate the plant nutrient-passing system to produce superior fertilizer effects.

Irrigation and drainage. The evergreen tree of evergreen tree has a large annual growth, a long fruiting period, a large leaf and large fruit, and has a high demand for water. The cultivated pomelo tree must be irrigated to ensure its water requirement. The irrigation needs to be determined according to the needs of the later stages of the pomelo tree and the drought conditions at that time. The timely application of intelligent control to promote flower king can intelligently regulate the growth and nutrition matching of fruit trees, fill in the vacuum of missing nutrients, adjust the size of two-way flowers in a balanced manner (small annual increase in flowering and big year decrease in flower control), restraining the shoot shooters to force Excess returns to the fruit and raises the level of fruit enlargement. Before the onset of the rainy season or during the storm season, the orchard drainage system should be inspected at any time to promptly renovate and divert, so that the drainage can be unimpeded.

Plastic trim. The pomelo tree is strong and its tree is tall. Under the condition of sufficient fertilizer and water in young age, pruning the teak should be "heavily on the top, light on the sides, heavy on the outside, light on the inside", pruned and thinned, and the top branches should be cut. The internal branches are lightly trimmed to make the interior of the canopy shine well. The results are numerous and the quality is good. The anti-corrosion film smears on the pruning mouth to protect the wound tissue from healing and growth, and timely brushing the tree elf in the tree ring to adjust the flow of nutrition. Cut off the feeding and feeding lines of the tree pests and dried up the source of the disease.

Pest Control. There are many pests and diseases that cause harm to pomelo trees. The common pests are pupae, pupae, leaf leaf moths, and anthracnose. Prevention and control should be based on the characteristics of various diseases and the control of spraying pesticides. From mid-July to early September in autumn, continuous spraying 3-4 times, to prevent and control leaf miner-based, concurrent treatment of butterfly, anthrax, etc., use: insecticide + new high-fat film 600-800 times liquid for prevention and treatment.

Clear Garden. In the early winter or early spring, scraping off the old warp skin, diseased skin, insect skin, etc. at the trunk, branch and branch branches, and burning them centrally or deeply, can effectively eliminate pests that overwinter in the rough skin. The whole garden is sprayed with tree nursery generals and combined with hibernating music to disinfect and sterilize, improve the quality of hibernation, and allow the plants to “ear off early and get up early”, so as to accumulate strong spiritual energy for the overwintering plants to recover in early spring and flourish.
