Abstract:
The effects of different pesticides treatments on chlorophyll (SPAD) value,photosynthesis rate and yield of greenhouse muskmelon,watermelon and tomato,respectively,and soil nutrient and microbial flora were studied through field experiment,by which could screen suitable application of drip irrigation of biological agents compared with CK.The results showed that the drip application of chemical agent had little effect on SPAD,photosynthesis rate and yield of greenhouse vegetables,and soil nutrients contents and microbial flora numbers.However,there were promoting effects of drip application of biological agents and complex microbial community on SPAD,photosynthesis rate of greenhouse vegetables,and phosphorus and potassium nutrient activation.Meanwhile,drip irrigation of biological agents could increase the yield of greenhouse tomato and muskmelon significantly,but had insignificant effect on the yield increment of greenhouse watermelon.Furthermore,the drip irrigation of complex microbial community could improve the yield increment of greenhouse tomato,muskmelon and watermelon markedly,which was 18.78%,23.52% and 25.92%,respectively.The drip irrigation of biological agents had the maximal function on enhancing the beneficial soil microbial communities and ameliorating the soil micro ecological environment,compared with which,the drip irrigation of complex microbial community had less improvement.
