随着蔬菜产销政策的放开,种植业结构的调整,大棚蔬菜有了很大发展。但生产中普遍存在环境封闭、湿度大和病害重的生产难点,使其社会经济效益不能得到充分发挥,阻碍着大棚蔬菜生产的进一步发展。由于湿度是病害多发、危害严重的主要因素,我们从降低空气湿度、控制发病条件着眼,结合地膜覆盖,应用滴灌灌溉技术,收到了明显的成效。下面就在黄瓜大棚中的应用情况,介绍一下该技术的做法和特点:
With the release of vegetable production and marketing policy, the adjustment of planting structure, greenhouse vegetables have great development. However, production is generally confined to the environment closed, heavy humidity and heavy production difficulties, so that their social and economic benefits can not be given full play, hindering the further development of greenhouse vegetable production. Since humidity is a major factor causing serious disease and serious harm, we have notable achievements in reducing air humidity, controlling disease conditions, combining with mulching and drip irrigation. Here’s the cucumber greenhouse application, introduce the practices and characteristics of the technology:
