摘  要:
[目的]探索有利于提高丝棉木苗干高的措施。[方法]应用正交试验方法,进行不同基肥施用量与施水量、不同苗木年龄以及栽植密度的试验。[结果]试验结果表明,对苗干高度影响最大的因素是移植的苗木年龄,其次是施肥施水量,而栽植密度的效应不显著。在试验条件下,以30 cm×30 cm的株行距,栽植2年生的苗木,栽后平茬,在施基肥的基础上,追施硫酸铵2~3次,每次施肥量112.5kg/hm2,追施尿素1次,施用量75 kg/hm2,全年灌溉5~6次,连续进行2年,可使苗干平均高度达到庭荫树的标准。[结论]较大的苗龄和较高的施肥施水量有利于提高苗干高度。

摘  要:
[Objective]The research aimed to study useful measures to increase the under branch height of Euonymus bungeanus Maxim.[Method]Orthogonal tests were carried out with different fertilizing amounts and watering amount,seedling ages and seedling density.[Result]The results showed that seedling′s age is the most significant influence element,the fertilizing and watering amount comes second and the density has insignificant influence.Under the conditions of this experiment by spacing in the rows and spacing between rows of 30 cm×30 cm,a young seedling of two year old was transplanted,fertilized with ammonium sulfate of 75 kg / hm2 for 2-3 times and urea of 75 kg/hm2 for onetime following basal application of fertilizer,and watered for 4-5 times a year.The average under branch height will reach the standard of shade tree.[Conclusion] Higher seedling age and larger fertilizing/watering amount are more effective in increasing under branch height.
