全国各地的丘陵山地综合开发果业已成为一些乡镇的支柱产业。然而,要获得更加理想的经济效益、社会效益和生态效益,就必须依靠新技术进行一场果树管理的革命。传统的施肥方法是将肥料埋在地下或撒在地里,让果树的根部吸收再把养分输送到其他部位。但是近年来,在西方先进国家中的许多果园里,已逐渐推广一种更佳的施肥技术。人们用注射方法把肥料稀释液注射到果树的树干内,肥料中还配有杀虫剂、杀菌剂、植物生长调节剂和微量元素。这样,不仅几道工序合而为一,既施肥、防虫、治病,又节省
The comprehensive development of hilly and mountainous regions throughout the country has become the pillar industry of some towns and townships. However, in order to obtain more desirable economic, social and ecological benefits, it is imperative to rely on new technologies for a revolution in the management of fruit trees. The traditional fertilization method is to bury the fertilizer in the ground or sprinkle in the ground, so that the roots of fruit trees to absorb the nutrients to other parts of the delivery. However, in many orchards in advanced western countries, a better fertilization technology has been gradually promoted in recent years. Injections are made by injecting fertilizer dilutions into the trunk of fruit trees, and insecticides, fungicides, plant growth regulators and trace elements are also included in the fertilizer. In this way, not only a few processes into one, not only fertilizers, pest control, treatment, but also save
