Research On The Effects Of Temperature On Dangtu YiJiDao Variety Characteristics

Because rice is an open production,heavily influenced by the natural environment and vulnerable to the impact of extreme weather.Therefore,in the actual production requires according to the regional climate characteristics,the selection of a suitable local,strong comprehensive resistance varieties,in order to enhance the anti risk ability of crops,to disaster mitigation,agricultural efficiency and farmers income and provide a powerful guarantee.In July to August 2013 and 2014 July to 8 months of abnormal climate,the abnormal weather(high temperature)of Dangtu County rice growth developmental effects were investigated in a large number of,and gives relevant suggestions according to the results of the survey.Agricultural and technical guidance,to fully understand the extreme temperature of Dangtu County season rice growth and development,based on the extensive investigation and Study on the 2013 years 7,8 month and 2014 7,8 month of continuous high temperature and low temperature and rainy weather on Hybrid Rice biological traits,yield components and yield were studied.The main results and suggestions are as follows:(1)to promote tolerance varieties resistant or resistant to high temperature and low temperature resistance,etc.);(2)adjusting hybrid rice seeding period,vigorously promote Jicha Yang,to avoid heading and flowering period of high temperature;(3)high temperature by deep water irrigation,the field cooling humidification;(4)strengthening the rice diseases and insect pests prevention and control work Poor performance of Japonica rice business personnel training,(5)is recommended in the county planted indica varieties are:Y Liangyou No.6,new Liangyou 1671,Wan rice 153,the emblem of Liangyou 996 and Liangyou 6 number.Japonica varieties are:Zhendao No.11,the town on the 18th,when Yujing No.10 and when 8.At the same time,in the county of indica varieties are:Liangyou 0293,Anhui rice 119(Liangyou 6326),agricultural Fengyou 1671,Green Feng 20 and Liangyou 766 japonica type varieties are:Wuyunjing 7,Wuyunjing 23 and when Yujing 2 number.
