How to grow a pomelo tree well
Today, the editor will explain how to grow pomelo trees well and share some tips on pomelo tree care and related experience in flower planting. Next, let me introduce to the netizens.
GRAPEFRUIT is known as natural canned food, with large fruits, clear and transparent flesh, unique flavor, and rich nutrition. The fruit has a sweet and sour taste. The skin of mature fruit is yellow or orange, and the flesh is white or red. It can be eaten raw or processed again, and it has high economic value. It contains vitamin C and vitamin B, etc., so it is a health product beneficial to the human body. In recent years, through comprehensive technical measures, it is possible to achieve early fruiting, high yield, and high-quality cultivation, which has positive significance for improving planting efficiency.
Firstly, choose a sunny and good arable land, and ensure that the terrain is open, flat, with sufficient water supply and convenient for irrigation and drainage. For seedlings, you can choose dwarf, early flowering, and high-yielding citrus. Transplant seedlings in the nursery with a plant spacing of 9-10 cm and a row spacing of 1-20 cm. Generally, the grafting time should be from the end of August to the end of September, and attention should be paid to the shaping of the support pole during this period.
Pomelo trees are adaptable and can be planted on various terrains such as hills and low mountains. Before planting, dig a pomelo groove first, mainly using organic fertilizer, apply sufficient base fertilizer, arrange the orchard reasonably, scientifically plan the planting density, and arrange roads, irrigation, and drainage facilities to fully utilize space, sunlight, and soil power, to ensure increasing leaf area and good income.
It is necessary to select good cultivation varieties to ensure they are disease-free and strong, and avoid mechanical damage during the transportation of seedlings. Since pomelo trees have a large tree body after maturing, it is appropriate to dig planting holes during the planting process and control their depth to 80-100 cm. During planting, apply the seedlings and organic fertilizers in layers with soil. After planting, water the roots sufficiently and cover them with materials.
After the tree crown gradually forms, measures to promote flowering are taken to regulate the tree body and convert it to reproductive growth, such as cultivating healthy and fruiting mother branches to prevent diseases and pests. Control the supply of water and fertilizers, and reduce soil moisture by controlling water supply in autumn and winter. In autumn and winter, expose and dry the roots to control water absorption rate. The circumcision operation focuses on trees entering the fruitless period. Generally, the circumcision operation is performed in mid-to-late September to promote flowering. A suitable large electrician's knife can be chosen. Cultivate strong and sturdy mother branches, especially one-to-two-year-old spring shoots, and manage fertilizers and water during the spring flowering and young fruit period, and reasonably control the available nitrogen fertilizers to avoid over-fertilization, which is not conducive to the fruiting of pomelo trees. Varieties like Shatian pomelo require manual pollination. When the flower calyx is cruciform, remove the calyx and pistil in sunny weather and perform direct artificial pollination to increase the fruit setting rate. At the beginning of the first and second physiological fruit drop periods, spray gibberellin to preserve the fruit and increase the fruit setting rate. For young trees with vigorous growth, a circumcision operation can be used to preserve the fruit. If there are fewer flowers on the tree, it should be done throughout the flowering period.
How to grow a pomelo tree well
Pomelo trees should mainly be fertilized with farmyard manure and ensure sufficient nutrition during growth. Young trees should be based on nitrogenous fertilizers and properly use potassium and phosphorus fertilizers, following the principle of frequent and fine fertilization. The fruit trees require at least 3 fertilizations during the first fruit, at harvest time, and the second spring sprout and strong fruit periods. Subsequent topdressings are determined based on their actual growth and soil fertility.
In most regions of China, the precipitation from June to September is very high. Taking Shatian pomelo as an example, the number of flowers per plant can exceed 10,000 during the production period, and the hot rainy season can easily exacerbate diseases and pests, leading to more severe fruit drop. To reduce economic losses caused by fruit drop, it is necessary to adopt preservation techniques to reduce the fruit drop rate. Flowers that are incomplete, abnormally numerous, in poor environmental conditions, with insufficient nutrient supply, hormonal imbalance, and diseases and pests are also major causes of abnormal flowering and fruit drop in pomelo trees. Measures can be taken to prevent this situation.
Due to the spring sprouts and early flower buds of pomelo trees, their nutrition mainly comes from the accumulation of the tree body, so applying winter fertilizers is very important. Root absorption and leaf nourishment can provide the nutrients required for sprout and later flowering development. Therefore, a fertilizer can be applied before the spring sprout to promote strong sprout growth, mainly high-nitrogen fertilizers, which can be used with humic acid water and fertilizers. During the growth period of new sprouts, topdressings should be combined with leaves to add some potassium and zinc.
Currently, for fruit preservation, commonly used regulators are gibberellin and cytokinin, etc., which are sprayed once when the flowers are 2/3, mainly containing gibberellin, cytokinin, and seaweed fertilizer. After 30 days, the second spraying is stopped when the diameter of young fruits exceeds 2 cm to avoid plant toxicity.
After many flower buds, promptly remove excess and deformed flower buds, leaving 1 to 2 inflorescences in the middle of each fruiting mother branch and 2 to 3 flower buds in each inflorescence. For trees with fewer flowers, they can be thinned or thinned. After the first physiological fruit drop, multiple fruit thinning can be performed, thinning small and deformed fruits, etc. For trees with many flowers, some overly vigorous spring shoots can be removed to reduce the absorption of nutrients by new sprouts. When it approaches maturity, multiple effects can be sprayed on summer sprouts. For poor-quality varieties, artificial pollination should be arranged. In cases of continuous rainy weather during flowering, when it is difficult to use preservation drugs, a circumcision operation can be used to preserve fruit. If the flowers are too weak, this method cannot be used.
For gummosis, a sharp knife can be used to cut vertically in the flowing gum area and apply a mixture of methyl thiophanate and garlic to the wound, with another application after 3-5 days, and it can be cured after 3-4 times. Ants and longicorn beetles should be treated generally or selectively according to specific conditions, using insecticides or a mixture of Rossel and Dinotefuran.
The above is an introduction to how to grow pomelo trees well and some tips on pomelo tree care, which can be used as a reference for everyone.
