Compared to conventional rice,Hybrid rice seed production has higher economic benefits and more complex pest control environment.With the rapid progress of urbanization in China,rural labor can not meet the needs of production,implementation of hybrid rice seed production specialization of the rule of defense has become a trend.How to make use of the specialized system of prevention and control of hybrid rice seed production is the future direction of development.To this end,the author of this article relies on his unit to study the specialization and control system of hybrid rice seed production.In this paper,the prevention and cure of diseases and insect pests in hybrid rice seed production field was first written,which was summarized and deepened The main contents include seed dressing treatment,rice planthopper,rice leaf roller,Chilo suppressalis(Walker),rice blast,Kernel Smut of Rice,bacterial root rot and other major pests and diseases of field control techniques,How to choose the medicament,how to determine the time and the best application of pesticide application environment.The innovation of this paper is focused on the prevention and control of plant diseases and insect pests by the plant protection unmanned aerial vehicles(UAV).Through the rigorous field experiment,the application of the flying control in rice blast,rice planthopper,weeding and pollen pollination research content.The results show that In the control of rice blast disease,the rate of disease control was reduced to 2,85%,2.26%and 1.34%respectively after 3d,7d and 14d,respectively.The rate of artificial spraying was 2.82%,2.24%and 1.47%respectively.The results showed that the control effect was not obvious,and the control effect was not obvious,and the control effect of preventing and controlling was as follows;in the control of the rice planthopper,the rate of insect reversion was 85.28%,95.65%and 96.88%at 3d,7d,The results were 71.60%,83.11%and 91.83%,respectively.The rate of artificial spraying was 83.14%,93.58%and 95.53%.The insecticidal effect was 67.47%,75.01%,88.29%.The effect of anti-fly prevention and control slightly better than the artificial control,the overall control is better.In addition to spraying weeds,6d after the drug,flying anti-basically eliminated the weed all,15d after the drug also did not find the phenomenon of injury.On the pollination,the rate of electric single rotor,swimming single rotor,sixteen rotors and artificial pollination were 39.8%,41.5%,33.2%and 36.6%respectively.Compared with the artificial pollination,electric single rotor,swimming single rotor could do a better job on pollination.This article has also done a research on the promotion and application of the system and other contents.
