关系果树全年正常生长的早春管理。这一时期,有机肥施用和落叶还田相当重要,应在去冬管理的基础上,加大有机肥施用量,有机肥与果品产量的适当比例要掌握在1.5∶1,去冬落叶应与有机肥一起开沟施入树下。早春除虫是保证果树健康的基础工作。,树下土壤和老树皮是许多害虫隐藏过冬的主要掩体,因此,去冬没有刮皮的树木要及早刮去粗皮、翘皮,把刮去的老皮深埋地下或烧毁,并对树下土壤进行一次深翻(深度为18-20公分),在杀灭害虫的同时,还可以松化土壤,提高地温,促进根系对土壤养份的吸收。在果树发芽前,即2月底3月初,普遍喷洒一次3-5波美度的石硫合剂,以利杀菌灭虫。
Early spring management of fruit trees that normally grow throughout the year. This period, the application of organic fertilizer and fallen leaves is very important, should be based on the winter management, increase the amount of organic fertilizer, organic fertilizer and fruit production should be controlled at an appropriate ratio of 1.5: 1, Organic fertilizer ditching together into the tree. Early spring pest control is to ensure the health of fruit trees. , The soil under the tree and the old bark are the main shelters that many pests hide during the winter. Therefore, the trees without the skin scraping during the winter should scrape off the bark and the skins as soon as possible, and the scraped old bark should be buried underground or burnt down. Under the soil for a deep turn (depth of 18-20 cm), while killing pests, but also loosen the soil, improve ground temperature and promote root absorption of soil nutrients. In the fruit tree before germination, that is, by the end of February early March, the general spray 3-5 Baume degree of lime sulfur mixture, to facilitate sterilization pest control.
