一、忌随意改变温室受光角度。现在栽培黄瓜的日光温室的角度是经过长期科学论证的,它的南北跨度、高度及后坡角度不要随意改变。二、忌定植时集中施肥。各种化学肥料特别是氮肥,在潮湿高温时,会产生大量的有害气体,如集中施在定植沟内,能导致黄瓜烧根死苗。
First, avoid free to change the greenhouse light angle. Now the greenhouse cultivation of cucumbers perspective is the result of long-term scientific demonstration, its north-south span, height and back-slope angle should not be arbitrarily changed. Second, avoid planting concentrated fertilization. A variety of chemical fertilizers, especially nitrogen fertilizer, will produce a large number of harmful gases when humid and high temperature, such as centralized application in the planting trench, can lead to cucumber seedlings dead.
