介绍了气态N3-（叠氮基）的生物学效应、杀虫原理、杀虫效果，N3-被太阳光等降解为N2的影响因素、N3-的寿命，以及实用时N3-浓度检测法等。试验结果表明，N3-杀虫法可取代农药（磷化物）杀虫。N3-稀溶液浸湿种子，可以延缓湿种子萌发始期，阴雨天可防止湿种子霉变、发芽．N_3~-
The biological effects of gaseous N3- (azido), insecticidal principles, insecticidal effects, N3-affecting factors such as degradation of sunlight by N2, the life span of N3-, and the practical N3-concentration assay . The test results show that, N3-insecticidal method can replace pesticides (phosphide) insecticide. N3-dilute solution soaked seeds, can delay the onset of wet seed germination, rainy days to prevent wet seeds mildew, germination. N_3 ~ -
