Study on Prevention and Control Technology of Diseases, Insect Pests and Weeds in Organic Rice Production
摘要
Abstract
In order to investigate the effective prevention and control technology of the organic rice diseases ,insect pests and weeds ,the contrast experiment of rice-duck-light ,rice-duck ,rice-light ,and conventional pesticide treatment was arranged ,the treatment without duck ,light and pesticide as the control .The results showed that at 15 days and 45 days after feeding duck ,the control effects of rice-duck-light and rice-duck treatment against barnyard grass ,Monochoria v a-ginalis ,rhizoma sparganii weed ,sedge ,and spirogyra were respectively 75 .5% -90 .5% ,77 .6% -89.6% and 88 .8% -100 .0% ,85 .1% -100 .0% .And the general control effects were 85 .5% , 84.3% and 91 .5% ,89 .8% ,respectively .The two treatments significantly exceeded the others . During the tillering peak period of rice ,the cluster incidence of rice sheath blight of rice-duck-light treatment and rice-duck treatment was respectively 38 .2% and 38 .5% ,69 .0% and 70 .4% higher than the control .The disease index was respectively 21 .4 and 23 .3 ,57 .4% and 53 .6% lower than the control .In the full panicle stage ,the cluster incidence and the disease index of rice-duck-light treatment and rice-duck treatment were respectively 12 .1% ,11 .6 and 12 .6% ,11 .8 ,lower than the control and that of the tillering peak period .At 18 days after feeding duck ,the conventional pesticide treatment had the best control effect against leafhoppers ,without siginificant difference from the rice-duck-light treatment .In addition ,the rice-duck-light treatment showed the best con-trol effect against Chilo suppressalis ,rice leaf folder ,and rice planthopper .At 50 days after feed-ing duck ,the rice-duck-light treatment showed best among all treatments in the control effect a-gainst Chilo sup p ressalis ,leafhoppers ,rice leaf folder ,and rice planthopper .Overall ,using the rice-duck farming technique and installing frequency vibration-killing lamp can effectively prevent and control diseases ,insect pests and weeds in the production of organic rice .关键词
