The proposed deep convolution network could learn the highdimensional feature representation of images by using their depth. An inception module was used to construct a neural network. In the inception module, multiscale convolution kernels were used to extract the distributed characteristics of soybean pests and diseases at different scales and to perform cascade fusion. The model then trained the SoftMax classifier in a uniformed framework. This realized the model of soybean pests and diseases so as to verify the effectiveness of this method. In this study, 800 images of soybean leaf images were taken as the experimental objects. Of these 800 images, 400 were selected for network training, and the remaining 400 images were used for the network test. Furthermore, the classical convolutional neural network was optimized. The accuracies before and after optimization were 96.25% and 95.81%, respectively, in terms of extracting image features. This type of research might be applied to achieve a degree of automation in agricultural field management.展开更多

Until now, 404 species on soybean have been known based on literature review and a large scale survey. More than 20 key pests occur every year and are causing serious damage. In 3 different ecoregions(Northern ecoregion, Huang-Huai-Hai ecoregion and Central south ecoregion), pests occurrence and damage styles show a variety of regional characteristics. Soybean pests occurrence from north to south were shown as follow: from large pests to small pests, from chewing pests to sucking pests, from low reproductive rate and less generation pests to high reproductive rate and more generation pests. Soybean pest management is mainly based on resistant breeding, combining with monitoring, plant quarantine, cultural, biological, physical, mechanical and chemical controls in China. Although pesticides play an important role in practice, the absence of reasonable use has threatened sustainability of China's soybean production. Soybean integrated pest management is not the only strategy, and it still needs improvement and development, but it's the best alternative for pest control. It can be expected that integrated pest management will remain as the main strategy for soybean pest control in future. Further innovation of green prevention and control technology will also become a focus of future research in view of new pest problems brought about by crop restructuring, agricultural system change and global climate change. Integration of above technologies will reduce the harm of pests and production costs as well as improving soybean production capacity. In this review, research progress of Chinese soybean pest and its management was summarized and some suggestions were provided to adapt for soybean pest management under current situation.展开更多

[ Method ] Three kinds of lamps with different wavelengths were used to conduct pest control test in soybean fields. [ Result] The trapping effects of three kinds of lamps with different wavelengths on soybean pests were significantly different. Among them, the trapping effect of No. 2 light with wavelength of 400 -460 nm was significantly better than the other two lamps; No. 1 light with wavelength of 330 -400 nm had no obvious difference in trapping effect with No. 3 light with wavelength of 450 -510 nm. [ Conclusion] The research result provided theoretical basis for popularized application of trapping lamp in production.展开更多

Nearly 90% of the world^s soybean production comes from these countries. The occurrence of diseases and insect pests often lead to the reduction of soybean yield, and brings varying degree losses to these countries. This article provides an overview of the impact and measures on soybean main diseases and insect pests in the top five major soybean producing countries over the world. It is concluded that the diseases affecting the soybean yield seriously include Phakopsorapachyrhizi, Heterodera glycines, Septoria glycines, Colletotrichum spp. and Macrophominaphaseolina; and the main insect pests include Anticarsia gemmatalis, Spodoptera litura, Nezara viridula and Frankliniella occidentalis, which will provide information for key prevention and control of soybean main diseases and insect pests in these countries.展开更多
