The Research About Suitable Fruit Cropload Of Zuijinxiang?shine Muscat?xinnongle Grape Varieties Under Propected Cultivation

The three grape varieties that are Zuijinxiang,Shine Muscat,Xinnongle have extensive planting area in east of China.By the development of grape industry,a lot of fruit farmer in many counties have consided this industry as the main ways to get richer.Under the condition of pritected cultivation,the research on the cropload is insufficient,the problem such as the load is too high,and the overall output is too high have seriously affected the quality of the grapes and the long-term development of the orchard.So reaearch about the Suitable fruit cropload of these three grape varieties will have a great significant about perfect ingeast grape cultivation technique and promoting the development of grape industry.After the reaearch about effect of diffreent fruit cropload treatments on Vegetative growth,root metabolic activity,Photosynthetic performance,new tip maturity,fruit yield and quality for Zuijinxiang,Shine Muscat,Xinnongle grape varieties,this paper get the following conclusions:the suitable fruit cropload for Zuijinxiang,Yangguangmeigui,Xinnongle grape varieties is 10 fruit allowance per square metre on plane surface.Under this fruit cropload condition,although it can not imprive Photosynthetic performance indexes and some of vegetative growth indexes,it can ensure the yield and quality of the grape,and improve the whole vegetative growth of plants,metabolic activity of root system and the new shoots of maturity,which will make the plant growth and development indexes to reach a relatively high level and improve the whole quality.So under the Climate and soil conditions that is as same as the Shanghai academy of agricultural sciences ZhuangHang comprehensive experimental station,this paper suggests to choose the fruit loading of 10 fruit cropload per square metre on plane surface.
