不同穴密度和杀菌剂对水稻纹枯病田间防效研究
Field Control Effects of Different Planting Density and Fungicides on Rice Sheath Blight
摘要
Abstract
In order to screen out the best density of rice cultivation,high efficiency and low toxicity of chemical agents,the effects of different planting density and six kinds of fungicides on the control efficacy and yield of rice sheath blight were studied by field experiment.The results showed that 4 plants per point was the best density,the incidence of sheath blight disease and disease index were low;under the designed dose,six fungicides had a certain control effect on sheath blight.However,the application of 250 g·L.-1 emulsion pyraclostrobin,the incidence of sheath blight disease was 12.8%,disease index was 3.5,the control effect was significantly better than the other five agents.At the same time,it had a significant effect to increase yield,the yield was up to 10 747.5 kg·hm.-2.关键词
