Current management of pomelo, mango, and Japanese apricot
In the south, thin-skinned melons are mainly cultivated in open fields on high ridges. In the middle and lower reaches of the Yangtze River region, direct sowing in mid-April or transplanting cotyledon seedlings in late April is suitable; if plastic film mulching is used, direct sowing or transplanting can be done 3-5 days earlier than usual. 1. Soil selection and crop rotation arrangement: It is advisable to choose a site with higher terrain, good drainage, and...
1. Pomelo: June is the fruit-setting period, with young fruit development. ① Thin fruit on trees with heavy fruit set, removing deformed, undersized, and excessive fruit. ② Prevent waterlogging in the orchard; before and after storms, watch out for citrus canker and spray 30% copper oxychloride suspension concentrate at 600 times dilution, or 70% copper oxychloride soluble powder at 1200-1600 times dilution. ③ Continue scraping off the egg masses of the citrus longhorned beetle and the larvae that have just bored into the bark.2. Mango: The young fruit is in a rapid expansion period, and summer shoots are emerging. ① Promptly remove summer shoots. ② Bag the fruit for protection. The fruit-piercing noctuid moth is one of the most serious pests damaging mango during the ripening period, and the best control method is bagging. Newspaper or specially purchased bags can be used as bagging material. Spray pesticide before bagging to prevent pests. ③ Weed the orchard, especially the weeds within the tree basin. ④ Spray pesticide to prevent diseases and pests. ⑤ In some orchards, early-flowering mangoes ripen in early July, so carry out harvesting work well.
3. Japanese apricot: New shoots are emerging. ① Apply fertilizer promptly after harvest to cultivate new shoots. ② Prevent and control diseases and pests, promptly controlling scale insects, scarab beetles, longhorned beetle larvae, slug moths, and bagworms. Prevent and control anthracnose and leaf spot disease. ③ Spray pesticide before and after heavy rain to prevent disease and promptly drain accumulated water. ④ Remove weeds from the tree basin.
