一、病害1、加强肥水管理春季及时灌水施肥,加强肥水管理,增强树势,提高树体抗病能力。盛果期树在萌芽前以氮肥为主、同时增施微量元素,可防治各种生理性缺素。花前开沟施肥,多施有机肥,结果大树株施3-5公斤,幼树株施2-3公斤左右。施肥量视土壤肥力、树种、树龄、结果量而定,春旱地区尤为重要。一般在萌芽前、春梢生长期进行
First, the disease 1, to strengthen fertilizer and water management Spring irrigation and fertilization in a timely manner, and strengthen fertilizer and water management, enhance the tree vigor and improve disease resistance of trees. Sheng fruit trees in the bud before the nitrogen-based, while the additional trace elements, can prevent a variety of physiological deficiency. Ditch ditch before fertilization, more organic fertilizer, the results of large tree plant 3-5 kg, young plant applied about 2-3 kg. Fertilizer amount depending on soil fertility, tree species, age, the amount of results, spring drought region is particularly important. Generally in the bud before the spring shoot growth period
