作者： Jie LI Rongyue ZHANG Hongli SHAN Xiaoyan WANG Xiaoyan CANG Changmi WANG Zhiming LUO Jiong YIN yingkun huang Sugarcane Research Institute Yunnan Province Academy of Agricultural Sciences/Yunnan Key Laboratory of Sugarcane Genetic ImprovementKaiyuan 661699China

Sugarcane red rot caused by Colletotrichum falcatum Went. is an important epidemical fungal disease. The outbreak of large-scale epidemics would cause huge losses to sugarcane production. At present,the pesticide control effect is not ideal. Moreover,due to long-term continuous cropping and changeable climate in recent years,favorable conditions for the occurrence of red rot have been created. The disease was often prevalent in various sugarcane areas,caused serious damage and seriously affected the sugarcane production. With the rapid spread of the disease worldwide,the control of sugarcane red rot has become the hot spot in the field of sugarcane production and research. In this paper,the epidemic characteristics of sugarcane red rot were analyzed in combination with the field investigation. To provide theoretical basis for prevention and control of red rot in China and effective control the widespread occurrence of the disease,combined with the latest research results at home and abroad,we proposed to select resistant varieties mainly,use biological control agents such as Trichoderma spp.,Pseudomonas *** Bacillus spp. to treat the seed cane and soil,timely apply chemical pesticide in critical periods and strengthen scientific and effective comprehensive coordinated prevention and control measures such as field management against red rot.

[Objective] The paper was to provide scientific basis for popularization and application of 70% Thiamethoxam ZF. [Method] 70% Thiamethoxam ZF was selected and applied in the soil for controlling Ceratovacuna lanigera Zehntner and Baliathrips serratus Kobus. [ Result ] 70% Thiamethoxam ZF had good con-rol effect against C. lanigera and B. serratus. The optimum dosage of 70% Thiamethoxam ZF was 450 g/hm^2 （effective ingredients 315 g）. 70% Thiamethoxam ZF （ dosage per hm^2 ） mixed with the regular fertilizer （ dosage per hm^2 ） should be applied together in sugarcane planting and management from February to June. The control effects against C. lanigera and B. serratus were above 98.4% and 82.9% respectively. The actual yield and sugar content were increased by more than 34 290 kg/hm^2 and 6.8% respectively compared to blank control. [ Conclusion] 70% Thiamethoxam ZF was a new ideal pesticide with characteristics of sustained- release, long-lasting and low-toxic for controlling C. lanigera and B. serratus, and should be applied widely in the sugarcane planting area.

Agricultural Biotechnology 2019年第6期8卷 52-56页

作者： Jie LI Wenfeng LI Rongyue ZHANG Hong Li SHAN Jiong YIN Zhiming LUO Xiaoyan WANG Xiaoyan CANG yingkun huang Sugarcane Research Institute Yunnan Academy of Agricultural Science

This paper discussed and summarized the parasitic characters and the protection and utilization of 7 species of dominant natural enemies of sugarcane pests in Yunnan, China. Sugarcane pests are numerous and there are rich natural enemy resources in Yunnan sugarcane areas. There are more than 283 species of natural enemies against sugarcane pests in Yunnan, among which the dominant natural enemies with protection and utilization value and research significance include Trichogramma, Apanteles flavipes(Cameron) and Sturmiopsis inferens Townsend parasitic on sugarcane borers, Synonycha grandis(Thunberg), Lemnia biplagiata(Swartz), Chilomenes sexmaculata(Fabricius) and Thiallela sp catching and feeding on Ceratovacuna lanigera Zehntner, and Euborellia pallipes Shiraki preying on Saccharicocus sacchari(Cocherell), Dysmicoccus bohinsis Kuw, Trochorhopalus humeralis Chevrolat and Diocalandra sp. There is also one fungal parasite, namely Beauveria bassiana, which is widely distributed in nature, and can parasitize in a variety of sugarcane pests including sugarcane borers, Exolontha serrulata(Gyllenhal), Alissonotum impressicolle Arrow, T. humeralis and Otidognathus rubriceps Chevrola. It has a natural parasitism rate generally around 10% and certain natural inhibition effect on sugarcane pests. Reasonably protecting and utilizing natural enemies and giving full play to the natural regulation of natural enemies on pests are of great significance for protecting the ecological environment, maintaining the ecological balance of sugarcane fields, improving the comprehensive management level of pests, and promoting the sustainable development of sugar industry.

随着电磁环境的日益复杂和雷达辐射源信号类型的逐渐增多,如何有效地识别雷达信号类型成为一个重要的问题。为解决这个问题,提出了一种基于深度学习和集成学习的辐射源信号识别框架。该框架由特征提取和分类器设计两部分组成。第一部分,将雷达信号变换到时频域,利用栈式降噪自编码模型学习时频图像的特征。深度模型的训练采用无监督预学习和有监督微调相结合。第二部分,构造一个集成不同支持向量机分类器的模型对雷达信号进行识别。利用8种不同的辐射源信号验证了提出模型的有效性,结果表明结合这两种机器学习的方法有助于提高辐射源信号的识别正确率。

畸变雷达电磁信号会严重影响雷达侦察装备的探测性能。如何有效地识别畸变信号类型对侦察系统的精确感知具有重要现实意义。针对畸变雷达信号往往存在样本稀缺的问题,该文提出一种基于模型无关元学习的残差网络(MAML-ResNet)。算法首先利用正常雷达信号样本训练元学习器,然后在畸变信号样本进行精调,最后在仅有少量畸变信号样本下,实现畸变信号的识别。实验结果表明该算法有效地提高了在小样本数据下畸变信号的识别准确率。

针对传统的雷达辐射源信号识别方法在低信噪比环境下的正确率较低,且通常只适用几种特定的雷达信号的问题,提出一种基于距离特征的辐射源信号识别方法。使用k-means算法提取若干个聚类中心,分别计算雷达信号脉冲与聚类中心之间的DTW (Dynamic Time Warping)度量值,联合这些度量值作为k邻近算法的输入进行识别。仿真结果表明,在信噪比为3d B时,所提方法对6类雷达信号的识别率达到91%。与基于小波脊频级联特征的方法相比,所提方法也表现出更好的识别效果。
