大棚黄瓜嫁接苗成活率的高低,除亲合力和嫁接技术外,嫁接后的温湿度及光照管理极为重要。 一、保持湿度。黄瓜嫁接后1～3日内适时喷雾。上午嫁接的苗宜在中、下午各喷雾1次,第二天和第三天中午喷雾1～2次,也可在上、下午各喷雾1～2次,保持棚内相对湿度在90％以上。为防止接穗萎蔫,喷雾宜轻,防止水滴流入接口处。棚内湿度过高叶面结水滴时,在早晚适当通风排湿,防止病菌大量繁殖,致使接口霉烂。
Greenhouse cucumber grafted seedling survival rate, in addition to affinity and grafting technology, grafting temperature and humidity and light management is extremely important. First, keep the humidity. Cucumber grafted 1 to 3 days after the timely spraying. Morning grafted seedlings should be in the afternoon spray 1, spray the next day and the third day at noon 1 or 2 times, but also in the morning and afternoon the spray 1 or 2 times to maintain the shed within the relative humidity of 90% or more . In order to prevent scion wilt, the spray should be light, to prevent water droplets into the interface. When the shed humidity is too high foliage knot water droplets, appropriate ventilation in the morning and evening wetting to prevent bacteria multiply, resulting in mildew interface.
