What are the key technical points for summer management of kiwifruit?
1. Preventing wilting. Kiwifruit leaves wilt during the high temperatures of summer, mainly for two reasons: first, high temperature and drought, mostly occurring between 12 noon and 4 pm on sunny days, recovering in the morning and evening, usually occurring over large areas. When this happens, irrigate promptly in the morning and evening, and the wilting will be relieved. Second, the root system suffers from root rot, root-knot nematode disease, etc., which damages root function and causes pathological wilting. It is most severe at noon and lasts a long time; in severe cases symptoms also appear in the morning and evening, and it tends to occur sporadically. Once discovered, dig down to check the roots. If it is indeed caused by pests or disease, appropriately prune branches and leaves, remove some or all of the fruit, and use agents such as Nongkang 120 and Junlimie for root drenching.

Eggplants have the highest demand for nitrogen fertilizer, but in high-temperature seasons, each application of urea per mu should generally be controlled within 30 kg, because in high-temperature seasons, urea transforms relatively quickly after being applied to the soil, and after the plants have met their needs, the excess portion will be lost. Especially in sandy soil, the proportion lost will be even greater...
