近年来,菜农已越来越普遍地使用植物生长调节剂来控制或促进蔬菜的生长发育进程,特别是在茄果瓜类蔬菜上的应用尤为突出,这将有利于“菜篮子”工程的发展。 一、培育矮壮苗。蔬菜在育苗期往往会遇到光照少、温度低和连阴雨寒潮等不利气候而推迟移栽。在此情况下,往往会造成植株徒长,形成“高脚苗”、小弱纤细苗而降低菜苗素质。若使用矮壮素、多效唑等,在菜苗开始徒长时喷施,做到浓度不过高,次数不太多,就 In recent years, vegetable growers have increasingly used plant growth regulators to control or promote the growth and development of vegetables, especially in eggplant melons and vegetables, which will benefit the development of “vegetable basket” projects. First, cultivate short sturdy seedlings. Vegetables in nursery often encounter less light, low temperature and even adverse weather, such as cold and rainy cold and delayed transplanting. In this case, tend to result in the growth of plant-length, the formation of “high-footed seedlings”, weak slender and reduce the quality of vegetable seedlings. If the use of chlormequat, paclobutrazol, etc., when the seedlings start only when the long spray, so that the concentration is not too high, the number is not too much
