| Abstract: There are many kinds of diseases and insect pests which do great harm to cucumber, and the quality and taste of cucumber were influenced by traditional methods of application pesticides. In order to ensure that cucumbers supplied directly to Shanghai could meet the requirements of pollution-free, the green control measures combining agricultural control, ecological control, biological control and physical control were adopted in production bases, and the use of chemical pesticides was reduced by 30%. The comprehensive control effect reached more than 85%, effectively reducing the number of control, reducing pesticide residues in agricultural products. The yield increased by 600 kg per 667 m2 and value increased by about 600 yuan per 667 m2. The better economic, ecological and social benefits were achieved. |
