What are the management key points for young Shatian pomelo trees?
Shatian pomelo is a variety of pomelo with excellent quality. Pomelo not only has high nutritional value, but also has effects such as strengthening the stomach, moistening the lungs, nourishing the blood, clearing the intestines, promoting bowel movements, aiding digestion, and relieving alcohol toxicity. So how should young Shatian pomelo trees be managed? Let's learn about it together.
1. Fertilizer and water management
After young Shatian pomelo trees are planted, if there is no rain, water them once in the morning and once in the evening every week to ensure the seedlings survive. After that, water once every other day for half a month, and then the number of waterings can gradually be reduced. If there is too much rain, pay attention to drainage and flood prevention to avoid root rot. Under suitable temperature conditions, rooting begins half a month after planting, and at this time timely topdressing is needed, but only thin organic fertilizer water can be applied to avoid damaging the new roots. After that, fertilize 1-2 times a month, and the concentration also begins to gradually increase. During the growing period, in order to promote the formation of a high-yielding canopy in young trees, fertilization at this time should mainly use quick-acting nitrogen fertilizer.
2. Bud removal and shoot control
After planting and survival, for single-trunk young trees, cut the top at 50 cm above the ground to promote the sprouting of new shoots. Keep 3-5 new shoots growing in different directions and evenly distributed as main branches, then cultivate 3 secondary main branches on each main branch, and cultivate lateral branch groups on the secondary main branches. During each shoot period, pay attention to bud removal and shoot control for shaping. Generally, shoots can be released 3-4 times a year. Before each shoot release, in addition to applying sufficient base fertilizer, pay attention to removing the buds and shoots that emerge first, so as to promote more neat and robust new shoots.
3. Deep plowing and soil improvement
This work is especially important for planting Shatian pomelo in mountainous areas, and it is the key to success or failure when planting Shatian pomelo in mountainous areas. This is because mountainous areas are mostly barren, with low organic fertilizer content and poor soil structure, which is unfavorable for the root growth of Shatian pomelo. Therefore, within 3-4 years after planting, carry out one deep plowing and soil improvement throughout the orchard, bury sufficient organic fertilizer, and expand the planting holes, so that the roots grow deeply and widely, achieving the goals of early fruiting, high yield, and long life. Moreover, deep plowing and soil improvement will inevitably injure and break some roots, which can also promote the sprouting of new roots, thereby expanding the root network and promoting early fruiting and high yield of young trees.
4. Intertillage and weeding
In spring and summer, there is more rain, and weeds are very likely to grow. Shallow tillage can be carried out together with weeding, following the principle of not damaging the roots. In autumn and winter, the weather is dry, so intertillage can be carried out after rain to reduce soil moisture evaporation. In addition, orchards on hillside land should carry out intertillage, loosening of the soil, and mulching before the dry season arrives, in order to prevent drought, increase fertility, and improve the soil.
