窄冠速生刺槐培育技术研究

Study on Breeding Technology of Robinia Pseudoacacia L.

为了研究窄冠速生刺槐在惠水山区的培育技术,进行了插根育苗密度试验和幼林施肥试验。试验结果表明:窄冠速生刺槐最适宜的育苗密度是17株/m2(20 cm×30 cm),其次是22株/m2(15 cm×30 cm),最差50株/m2(10 cm×20 cm);幼林生长第1年最优的施肥组合方式为尿素25 g/株、氯化钾40 g/株。

In order to study the breeding techniques of Robinia pseudoacacia L. in Huishui mountainous area,the different interpolation - breeding density test and the young fertilization trial were done. The results showed that,the most suitable breeding density of the Robiniapseudoacacia L. was： 17 strains per square meter （ 20 cm-30 cm ）, followed by 22 strains per square meter （ 15 cm-30 cm ）, the worst was 50 strains per square meter （ 10cm-20 cm ）.Optimal combinations of fertilization in the first year of sapling growth was urea 25 g per strain and potassium chloride 40 g per strain.
