永顺地区湘林210号油茶种植对比试验

Comparative Experiment on Planting Camellia Oleifera No.210 in Yongshun Area

油茶须根多,较抗干旱、抗严寒,病虫害较少,是绿化荒山荒地、改善生态环境的好品种,是永顺县重点产业之一。通过对湘林210号(国S-SC-CO-015-2006)油茶苗木2种地类种植对比试验,结果显示,在石灰岩发育而成的耕地上种植的油茶生长旺盛、易丰产,第1、2、3年平均地径分别粗8%、19.6%、42.7%,第1、2、3年平均冠幅分别宽1.5%、25.5%、40.3%,第4、5年油茶果产量分别高39.1%、63.6%。

Camellia oleifera has many fibrous roots,is more resistant to drought and cold,and has fewer diseases and insect pests.It is a good variety for greening barren mountains and wastelands and improving the ecological environment.Camellia oleifera is one of the key industries in Yongshun County.The comparison test of two land types of Camellia oleifera seedlings in Xianglin No.210(National S-SC-CO-015-2006) in five years shows that Camellia oleifera planted on the cultivated land developed from limestone grows vigorously and is easy to produce high yield.The average ground diameter in the first,second and third years is 8%,19.6%and 42.7%,the average crown width in the first,second and third years is 1.5%,25.5% and 40.3% respectively,and the fruit yield in the fourth and fifth years is 39.1% and 63.6% higher respectively.
