采用传统喷雾法不仅用药量大、劳动强度高,而且在防病过程中,人为地增加棚室内湿度,客观上为病害传播蔓延提供了条件;采用烟雾法防治病害,较好地解决了湿度问题,但是烟剂在使用中对棚室密闭程度要求很严格,且药剂在燃烧中损失很多,生产上难以大面积推广。

The traditional spray method is not only used for large doses, high labor intensity, but also in the disease prevention process, artificially increase the greenhouse indoor humidity, objectively provide the conditions for spread of the disease; the use of smog method to prevent diseases, better solve the humidity problem , But in the use of smoke on the degree of airtight chamber requirements are very strict, and the loss of a lot of pharmaceutical burning, the production is difficult to promote large-scale.
