The latest course on the techniques and methods of promoting flower and protecting fruit of honey pomelo

Honey pomelo is refreshing and juicy, which is a favorite fruit of many people, and it is planted in many areas, but for fruit growers, what they want most is how to increase the yield, plus a large number of honey pomelo flowers, and there are more flowers and fruits in the planting process. So we need to do a good job in flower promotion and fruit protection technology. Let's take a look at the flower promotion and fruit protection technology of honey pomelo together with Xiaobian.

1. Strengthen the management of fertilizer and water

The occurrence rule is the key to the high yield and high quality of honey pomelo. According to the experiment, the yield of reasonable formula fertilization is more than 50% higher than that of random fertilization. Compared with the application of organic fertilizer and chemical fertilizer, its fruit taste is pure and the meat is fresh and tender. In production, according to the fertilizer demand characteristics of pomelo trees, the fruit trees should be fertilized 4-5 times a year, and the first fruit harvest fertilizer is mainly to restore the tree potential, accounting for 30% of the whole year; the second fertilization is pre-flowering fertilizer, mainly rotten farm manure, and the application of nitrogen fertilizer should be controlled after dilution; the third fertilization is stable fruit fertilizer, which is reasonably matched with nitrogen, phosphorus and potassium fertilizer. The fourth topdressing is strong fruit fertilizer, mainly quick-acting fertilizer to promote fruit growth, but the application of nitrogen fertilizer should be controlled to avoid fruit cracking. The principle of "spring dampness, summer drainage, autumn irrigation and winter control" is followed in water management.

2. Thinning flowers and fruits

Honey pomelo has a large number of flowers and consumes more nutrients, so it is necessary to pay attention to the light of flower and fruit thinning. First of all, according to the inflorescence, we should remove the inflorescences in the upper part of the crown and retain the inflorescences in the inner chamber and the middle and lower parts of the crown. When the buds are white, remove the buds from the head and tail of each ear in time, leaving only 2-3 robust buds in the middle. According to the tree potential and plant size, we should manually remove the excess young fruit in the young fruit stage to ensure a reasonable load. At the same time, we should also pay attention to the removal of disease and insect fruit, deformed fruit, small fruit, and finally according to the fixed number of fruits.

3. Ring cutting

Cutting the phloem through ring cutting treatment can inhibit the growth of root system, increase the carbohydrate content of the upper branch group of ring cut, increase the concentration of sap and the ratio of carbon to nitrogen, and increase the amount of flowers by about 20% and 30%. Ring cutting should choose the time according to the tree strength and the amount of flowers. when the young fruit trees with vigorous vegetative growth are cut, the flowering period with less flowers will be carried out, and the flowers with more flowers will be postponed to Xiehua. The depth of ring cutting should be directly to the xylem, and spiral, single-ring or double-ring can be used.
