摘要
[目的]研究栾树大苗在银川地区移栽后的生长和结实的适应性。[方法]以自河北省引种栽培的当年生无患子科栾树属落叶乔木栾树84株大苗为材料,研究了大苗移栽后的分枝、生长、生物量积累及结实特征。[结果]大苗移栽后,栾树成活率为100%,生长良好;当年具有较强的分枝能力,单株分枝数为(7.6±2.5),分枝长、基径、复叶数和生物量分别为(63.8±12.9)cm(、11.4±1.7)mm(、20.8±4.9)和(74.6±20.7)g。大苗移栽后当年有近50%的移栽植株能够结果,结果枝条约占总枝条数的33.3%,每一枝条平均结果(19.3±14.1)枚,但果实和种子成熟较成年植株有所推迟,部分果实和种子不能发育成熟。[结论]该研究为栾树在西北地区城市园林绿化和水土保持中的推广应用提供了基础数据。
[Objective] The aim was to study the adaptability of growth and fruiting of large seedlings of Koelreuteria paniculala after transplanting in Yinchuan area.[Method] Taking 84 large seedlings of 1-year-old K.paniculala,a deciduous arbor species of Koelreuteria Laxm,Sapindaceae introduced from Hebei province,as tested materials to study their characters of branch,growth,biomass accumulation and fruiting after the large seedlings were translated.[Result] After transplanting of great seedlings,the survival rate of K.paniculala was 100% and they could grow and develop well;K.paniculala had the strong branching capability in the same year and the total branching number per plant,branching length,basal stem diameter,paripinnate number and biomass of individual branch were（63.8±12.9） cm,（11.4±1.7）mm,（20.8±4.9）,（74.6±20.7） g resp.About 50% of seedlings and 33.3% of total branches fruited in the same year after transplanting and the average fruiting number of individual branch was（19.3±14.1）.But the development and maturation of their fruits and seeds were delayed and a part of them could not develop and mature.[Conclusion] This study provided basic dada for popularization and application of K.paniculala in urban landscaping and soil and water conservation in northwest area in China
