大棚蔬菜病菌种类繁多,发生规律复杂,加上大棚内湿度大,温度高,蔬菜轮作倒茬,因而大棚蔬菜病菌传播蔓延快,对蔬菜危害严重。如果使用农药,一是多次防治易使病菌产生抗药性;二是由于蔬菜生长期短,极易造成农药残留,严重危害人民的身体健康。在加入WTO后,农药残留超标也会阻碍蔬菜出口国外,影响到蔬菜的发展和农民收入的提高。江苏新沂天马电子器材总厂开发生产的适于蔬菜大棚使用的SW-009(3.5G)神威牌消毒杀菌机,是一种高效高浓度臭氧发生器。由于臭氧极
Greenhouse vegetables a wide range of bacteria, the occurrence of complex laws, coupled with the greenhouse humidity, high temperature, vegetable rotation cropping, and thus spread of greenhouse vegetable germs spread rapidly, serious damage to vegetables. If the use of pesticides, one is easy to make bacteria susceptible to multiple control; the second is due to the short vegetable growth period, can easily cause pesticide residues, seriously endangering the health of the people. After joining the WTO, excessive pesticide residues will hinder the export of vegetables abroad, affecting the development of vegetables and farmers’ income. SW-009 (3.5G) Shenwei brand sterilizing and disinfecting machine, which is developed and manufactured by Jiangsu Xinyi Tianma Electronic Equipment General Factory, is a high-efficiency and high-concentration ozone generator. Because of ozone pole
