| 摘 要： | 通过田间试验研究了稻草覆盖对油茶林地土壤温度和幼林新梢的影响.结果表明:稻草覆盖可以有效降低土壤温度,尤其在7～9月份的高温季节与对照差异显著,稻草覆盖条件下的土壤温度日变化平缓.由于覆草后改善了土壤的水热状况,所以覆草下的油茶长势良好,新梢长度高于对照.随着稻草覆盖量的增加.其对林地土壤温度及幼林新梢的影响也增大.各处理效果比较:D>C>B>A>E.

| Abstract: | Effects of straw mulching on soil temperature and fresh tip of Camellia oleifera young forest were studied by conducting field experiment. The results showed that straw mulching could decrease soil temperature effectively,showed significant difference with control during high temperature season from July to September. Daily changes of soil temperature under straw mulching were smooth. Straw mulching improved soil hydrothermal conditions,Camellia oleifera growed well and fresh tips were longer than control. ... |
