目前大棚蔬菜生产大规模发展,给农民创造了致富的大好时机,但是大棚与露地栽培相比,病害要严重,多样和复杂得多。由于农民缺少这方面的病理常识,防治不到位,效果不理想,费工费力枉费农民的劳动量,产量也受到限制。因此棚室的病害成为困扰农民进行大棚生产重要因素。 At present, the large-scale development of greenhouse vegetable production has created a golden opportunity for farmers to get rich, but the greenhouse diseases are more serious, diverse and complex than the open field cultivation. Because peasants lack the pathological common sense in this field, prevention and treatment are not in place, the effect is not satisfactory, laboriously expending the labor cost of peasants, and the output is also limited. Therefore, the disease in the greenhouse has become an important factor that plagued farmers to produce greenhouses.
