摘要: 采用四因素四水平的正交设计(L16(45)),研究了粘土地速生丰产林的栽培技术.3A的研究结果表明,741杨和抗虫榆比较适合在粘土地上生长;1354杨和中林115杨不适合在粘土地上生长,前者年均高生长率为后者的169.3%,年均胸高断面积生长率为后者的265.6%.粘土地的整地深度应达到50~70CM,这样可极显著提高造林成活率、保存率和生长量.如,树高和胞高断面积年均生长率为对照(30CM)的125.1%~183.2%和136.3%~211.13%.穴施2.5~5.0KG未腐熟的秸杆,虽然对成活率、保存串没有明显影响,但生长率分别为对照(不施秸秆)的144.3%~129.4%和128.6%~145.6%.粘土地旱作丰产林,如选择适宜树种和造林技术,其幼林阶段年均胸径生长率可接近或超过沙地有灌溉条件的丰产林,但树高生长率仅及沙地的41.2%.
