Experiment on Techniques for Changing Variety of Myrica rubra by Grafting and Its Popularization and Application

经连续 8年的改接换种试验 ,野生杨梅采取接后遮荫 ,防护、抹芽、立支柱、摘心和肥水管理、病虫害防治及应用疏花剂等措施可减少杨梅大小年 ,从而获得较明显的经济效益。试验结果显示 ,其投入与产出之比 ( 1 :5.52 )大于实生苗嫁接 ( 1 :1 .0 2 ) ,目前已推广 68.6hm2 ,已投产 3 4 .9hm2 ,年均净收入 1 6.52 6万元 /

years of experiment on techniques for changing variety of Myrica rubra by grafting showed that, after wild trees of Myrica rubra were grafted, the applied measures, such as sunshading, protection ,holding by column,heart-pucking Management of water and fertilier and pretention and cure of diseases and pests,could decrease the variation of on -year and off-year ,and consenquently obtained greater economic benefits The results of experiment indicated that,Ratio of input to output was 1:5 52,higher than that of the grafted seedlings At present ,these techniques have been already popularized in a area of 38 6 hectares,of which, 34 9 hectares have put into production and annual net income has been 16 5200 Yuan(RMB) per hectare
