冬季建立大棚温室生产蔬菜,学会遇到很多不良因素,影响到棚菜的正常生长发育。若在实行科学管理的同时,再巧妙地配以化控技术,即可获得适时应市、高产优质的棚菜收到事半功倍的理想效果。其具体做法如下一、育苗期化控棚室蔬菜在育苗期间,往往会遇到阴雨天气,温室内低温寡照,很易使菜苗生长成细弱高脚。定植后缓苗期长,成活率低,严重影响到大棚内蔬菜的产量。应视具体情况适时化控:1、喷洒1000-4000ppm的比久或100-200ppm的多效唑药液,则可培育出能抗寒、抗旱、抗病力强的短壮苗。
Greenhouses greenhouse greenhouse production of vegetables, learn to encounter many adverse factors, affecting the normal growth and development of greenhouse vegetables. If the implementation of scientific management at the same time, and then cleverly accompanied by chemical control technology, you can get timely due to the market, high-yield high-quality greenhouse vegetables received the ideal result with less. The specific practices are as follows First, nursery period control greenhouse vegetables during nursery, often encounter rainy weather, low temperature greenhouses, it is easy to grow vegetables into delicate feet. Huanmiao colonization long after the survival rate is low, seriously affecting the yield of vegetables in the greenhouse. Should be controlled as appropriate in due course: 1, Spraying 1000-4000ppm longer than or 100-200ppm paclobutrazol liquid, you can cultivate a cold stubborn, drought-resistant, disease-resistant short strong seedlings.
