摘要

The most serious potential hazard of cowpea product is the pesticide residue for controlling such pests as thrips and cowpea pod borer. To explore a safe and efficient mode of cowpea production that is fit for climatic characteristics of Hainan,ensure the safety of cowpea supply,minimize the use of pesticides,and control pests in physical means,insect-proof nets are applied in cowpea cultivation. We set 5-mm,2. 5-mm and 1. 67-mm insect-proof nets as three treatments and open filed cultivation as CK to explore efficiency of insect-proof net in cowpea production in terms of insect-proof efficiency,biological characters and commodity properties and yield of cowpea. The results showed that insect-proof cultivation was efficient in controlling pests,especially the 2. 5-mm net showed the optimal effect for cowpea production.
