摘要
大五星枇杷大树移栽试验表明,移栽前进行诱根处理,移植园地选择地下水位较低、土壤较肥沃的旱土,地下水位较高的水田移栽时,应用客土抽沟排水或非客土抽沟排水,适当的轻度疏删和回缩修剪,有利于提高枇杷大树移栽的成活率和树势的恢复,也有利于大五星枇杷的提前投产.引种试验结果表明,大五星枇杷在湖南株洲地区能正常生长、开花结果,丰产稳产,适应性强,成熟期比原产地早8～12 d.在栽培管理良好的条件下,大五星枇杷大树移栽2 a后株产可达5 kg,3 a生树株产10～15 kg,在控制产量、适度疏果的前提下,大五星枇杷可保持原产地大果质优的特性.
After the experiment of big tree transplanting of Dawuxing loquat had been carried out, the results of showed that roots induce treatment before big tree transplanting, the transplanting garden with lower underground water level and richer dry soil, the paddy field with higher underground water level which may use earth or alien earth and need dig trenches to drain the water away, in addition to lightly lighting and pruning of trees, were in favor of improving the rate of survival of loquat transplanted and resuscitation of growth vigor, and putting into production ahead of time. The results of introduction trial showed, the Dawuxing loquat could normally grow, bloom and bear fruit, get high yield and dependable crop, had strong adaptability in Zhuzhou, and date of maturity was 8~12 d before provenance＇s date. the yield of per individual tree can get to 5 kg after 2 years, and that of 3-year-old tree can get to 10-15 kg, if cultivation and management are well. Through controlling yield and reducing the number of fruits moderately, the Dawuxing loquat can retain the characteristic of big fruit and high quality.
