蔬菜在苗期、中期、后期都要选用叶面肥进行追肥,以促进茎叶生长和恢复生机,提高产量,改善品质。如果在防治病虫和使用植物生长调节剂时,能混合叶面肥一起喷施,便可获得治病(虫)施肥双重效果。现介绍三种类型蔬菜使用叶面肥的技术如下。1.叶菜类这类蔬菜的生长特点是全生育期需要肥水较多,尤其对速效氮更为敏感和迫切,如氮肥不足,则叶片发黄,生长迟缓,产量明显减少。所以这类
Vegetables in the seedling, mid and late foliar fertilizer should be selected for top dressing to promote the growth of stems and leaves and restore vitality, increase yield and improve quality. If the pest control and the use of plant growth regulators, can be mixed with foliar spray together, you can get the dual effect of treatment (insects) fertilization. Now introduce the three types of vegetables using foliar technology are as follows. 1. Leafy vegetables such growth characteristics of the whole growth period needs more fertilizer, especially for quick-acting nitrogen is more sensitive and urgent, such as nitrogen deficiency, the leaves yellow, growth retardation, output was significantly reduced. So this kind
