我们场于一九六九和一九七○年相继种植酸桔砧、小叶系温州柑一百五十株,种在蔬菜地里,树势越来越旺盛,但绝大部分至今仍未能开花结果。虽然有十多株开过少量花,但总是挂不起果或挂果很少,七年柑果总产才三百多斤,柑果树成了“风景树”。过去,我们曾适用除芽、抹梢、摘心等措施,以限制春、夏、秋梢的大量发生,促其开花结果,但效果却不显著。因此,我们于一九七六年十一月下旬,选择有代表性的酸桔砧,小叶系温州柑二十株(树冠高253—304厘米、冠围径802—924厘米、主干粗26—31厘米),进行断露晒根、铁丝结扎和环状
Our farm was successively planted with acid orange anvil in 1969 and 1970, and the leaflet was Wenzhou Wenchuan 150 species. In the vegetable fields, the tree vigor is getting stronger and stronger, but the vast majority have not yet been able to survive Bloom and bear fruit. Although there are more than a dozen plants that bloom a small amount of flowers, they often can not afford to hang fruit or hang fruit very little. Only three hundred kilos of total citrus fruit have been produced in seven years and the citrus fruit tree has become a “scenic tree.” In the past, we used to apply measures such as removing buds, scouring tips, and pinching hearts to limit the occurrence of spring, summer and autumn shoots and promote their flowering, but the effect was insignificant. Therefore, in late November 1976, we selected a representative sour anvil rootstock with leaflets of 20 strains of Wenzhou citrus (253-304 cm in crown height, 802-924 cm in crown circumference, 26-32 cm in trunk diameter, 31 centimeters), broken roots sunburn, wire ligation and ring
