Adaptability Of Shatangju In Different Climatic Zones In Guangxi

The yield and quality were analyzed for Shatangju collecting from16counties in Guangxi. Temperature to Shatangju was also analyzed according to Guangxi different region meteorological data. In addiction, ecological adaptability regionalization was studied for Shatangju in Guangxi according to temperature index. The results are as follows:1Stable yield was observed for different regional Shatangju and mean single plant yield was19～25kg for4-year old Shatangju tree. There was no obvious difference among average seed number of a fruit, fruit shape and fruit juice content. Low fruit quality was observed in Quanzhou, Nandan, Leye, Jinxiu, Dongxing. The fruit appearance was rough, or fruit surface smooth finish decreased. Soluble solids content and total sugar content decreased and total acid content increased. Fruit flavor was tasteless and fruit skin became thickness. Vitamin content increased, fruit flesh was non-melting pulps and and flavor became slightly acid.2Shatangju fruit quality declined under the following conditions:extreme minimum temperature less than-5℃, annual mean temperature≤17.7℃and≥10℃active accumulated temperature≤5295℃, annual mean temperature≥22.6℃and≥10℃active accumulated temperature>8012℃. Total acid content increased, fruit skin became thickness, and sugar acid ratio declined but fruit taste was still sweet, crisp and tender, melting pulps in annual mean temperature19.5～20.7℃and≥10℃active accumulated temperature6072～6707℃Fruit had good quality under the following conditions:annual mean temperature21.1～22.2℃and≥10℃active accumulated temperature7000～7650℃. 3Ecological adaptability regions division is as follows according to the annual mean temperature of different climatic regions,≥10℃active accumulated temperature, fruit quality:The best Ecological adaptability regions:Nanning, Chongzuo, Qinzhou, Guigang, Yulin city and its counties, Fangchenggang city, Wuzhou city, Cenxi, Tengxian, Cangwu, Pingguo, Jingxi, Debao, Napo, Shangsi county and most areas of Hepu, South of Tianlin, Bama, Duan, Dahua, WuxuanEcological adaptability regions:Hezhou, Liuzhou, Laibin, Baise, Hechi city, Zhongshan, Zhaoping, Mengshan, Pingle, Lipu, Luzhai, Liucheng, Liujiang, Heshan, Xiangzhou, Xincheng, Tiandong, Tianyang, Longlin, Xilin, Lingyun, Yizhou, Donglan, Fengshan county, North of Tianlin, Bama, Duan, Dahua, Wuxuan, South of Gongcheng, Tianer, Huanjiang.Less Ecological adaptability regions:Guilin city, Longsheng, Lingchuan, Lingui, Yongfu, Yangshuo, Sanjiang, Rongan, Rongshui, Fuchuan, Luocheng county, North of Gongcheng, Tianer, Huanjiang.Non-ecological adaptability region:Beihai, Dongxing city, Ziyuan, Quanzhou, Xingan, Guanyang, Jinxiu, Leye, Nandan county, Shankou town of Hepu county.
