摘要
[目的]了解欧李在成都地区的适应性。[方法]以引种欧李4号和欧李5号为材料,分别对其开花时间、花期长度、坐果率及植株的高度变化等进行观测,并对其物候期进行调查。[结果]成都地区欧李的开花时间较北方地区早,物候期较北方地区提前;欧李4号的开花期为8d,平均坐果率为19.48%,高度为44～60cm的植株坐果率较高;欧李5号的开花期为15d,平均坐果率为27.24%,最高植株与最低植株的坐果率相差11.91%;欧李5号的植株高度、开花量、最高坐果率、最低坐果率及平均坐果率等均优于欧李4号,但2品种在成都地区的生长状况均较好。[结论]欧李4号和欧李5号适宜在成都地区栽植。
[Objective] The aim was to understand the adaptability of Prunus humilis Bunge in Chengdu [Method] With P.humilis 4 and P.humilis 5 as the materials,the changes of their flowering time,florescence duration,fruit setting rate and plant height were determined,and their phenophase were investigated.[Result] The flowering time of P.humilis in Chengdu was earlier than that in northern china and their phenophase was advanced than that in northern china.The flowering stage of P.humilis 4 was 8 d with average fruit setting rate of 19.48%,and the fruit setting rate of the plant with height of 44-60 cm was higher.The flowering stage of P.humilis 5 was 15 d with average fruit setting rate of 27.24%,and the fruit setting rate of the highest and the lowest plant was differed by 11.91%.The plant height,flowering amount,the highest and the average fruit setting rate of P.humilis 5 were all better than those of P.humilis 4,but the 2 varieties were all grown well in Chengdu.[Conclusion] P.humilis 4 and P.humilis 5 were suitable for planting in Chengdu.
