荔枝新株系‘越州红’在钦州产区的栽培表现

Cultivation Performance of New Litchi Strain‘Yuezhouhong'in Qinzhou Production Area

将实生变异荔枝新株系‘越州红’在广西钦州进行引种,高接后第3~4年开始投产,成花株率100%,成花枝率99.0%,第3年的投产树产量9286.5kg/hm^(2),第4年最高株产112.3kg,平均株产70.9kg,产量28719.0kg/hm^(2);其果实可溶性固形物含量为20.7%,单果质量26.4g,焦核率89.3%;生长旺盛,表现易成花、迟熟、品质优、丰产性好等多项优良性状,性状与原产地栽培一致,为改善或调整广西早中晚熟品种搭配不合理、荔枝产期集中等突出问题提供备选品种。

The new seedling variation litchi strain‘Yuezhouhong'was introduced in Qinzhou of Guangxi.It was put into production in the third to fourth year after top grafting,with 100%and 99.0%success rates of flowering in plants and branches respectively.In the third year,the trees put into production produced 9286.5 kg per hectare.In the fourth year,the highest yield in a single plant was 112.3 kg,the average yield per plant was 70.9 kg,and the yield per hectare was 28719.0 kg.The content of soluble solids in the fruit reached 20.7%,the weight of single fruit was 26.4 g,and the scorch rate was 89.3%.The strain also showed strong growth,and other stable traits identical in its original habitat,including easy flowering,late maturity,good quality,high yield and more.The results provided an alternative that might help improve or adjust planting problems in Guangxi such as the unreasonable combination of early,middle and late maturing variations and the concentration of litchi production dates.
