林业生产上传统的扦插繁殖,通常是采用人工喷水、遮荫、盖草、设置塑料薄膜罩等方法,不仅劳动繁重,而且效率低。尤其是夏季扦插,天气炎热,空气湿度低,气温高,每天喷水少则4—6次,多则十几次,几十次,成本高,效果也不稳定。为了减轻劳动强度,节约资金,多产苗木,适应四个现代化的要求,有必要 The traditional cutting propagation in forestry production usually adopts artificial spraying, shading, covering grass and setting plastic film covers, which not only is labor-intensive but also inefficient. In particular, summer cutting, the hot weather, low humidity, high temperature, water jet 4-6 times a day, as many as dozens of times, dozens of times, the cost is high, the effect is not stable. In order to reduce labor intensity, save money, prolific seedlings, to meet the requirements of the four modernizations, it is necessary
