| At present,the prevention and control of rice diseases in the world is still dominated by chemical control.However,the high use of highly toxic and high-residue chemical pesticides causes damage to the ecological environment and poses a threat to the safety of humans and animals.With the improvement of people’s living standards,people are paying more and more attention to food safety.Due to the low toxicity and no residue of biological pesticides,there is no adverse impact on the ecological environment.The green prevention and control of agricultural pesticides based on biological pesticides has been favored by more and more people.The test was carried out in Chahe Town,Huai’an,Jinghe Town,Yangzhou City,Yonghe Town,Guangzhou,Luoqiao Town,Yancheng City,Henghu Farm,Nanchang.The field experiment of five different test sites was used to promote the application of microbial fertilizer“Ningdun”in rice production.There are 6 treatments in Huai’an City,which are blank control,conventional planting and BeMMG(0 Ningdun)and BeMMG(Ning Shield 2 times spray)BeMMG(Ningdun four sprays),BeMMG(Ningdun 4+1 sprays),through the BeMMG system set "Ningdun" different methods of use and usage,screened out 4+1 sprays The technique of using the secondary spray(when there is no water on the soil surface during the drying of the field),and studying the effects of each treatment on rice growth and rice leafhopper.Yangzhou and Guangzhou set up local organic and BeMMO systems;Yancheng and Nanchang set up conventional planting and BeMMO systems.It can be seen from the Huai’an rice weight loss and drug reduction experiment that the rice field using the microbial agent Ningdun is reduced by 354g/mu of chemical pesticides and 7Kg/mu of chemical fertilizer(68.7%of chemical pesticides and 12.6%of chemical fertilizers).At the same time,the increase of organic fertilizer 200Kg/mu+Ning Dun 0-3.5 liter/mu,rice production and net profit have improved.In the other four regional BeMMO system implementation plots,the beneficial microbial-driven whole-plant rice organic planting system has a small decrease in yield compared with conventional planting,but the net profit per mu of rice is about twice that of conventional rice,Yancheng and The net profit of rice in the BeMMO system in Jiangxi was 955 yuan and 883 yuan respectively.At the same time,compared with the local organically grown rice,the yield of the BeMMO system in Yangzhou and Guangzhou increased by 40Kg and 75Kg respectively,and the profit increased by 420 yuan and 365 yuan respectively. |
