| 摘 要： | 雷竹(Phyllostachys violascens)是一种优良的笋用竹种,覆盖栽培能够促进雷竹经济效益的显著提升。试验研究了新型覆盖材料麦灰和砻糠的覆盖厚度和施用方法对雷竹林地温及笋产量的影响。结果表明:覆盖材料的覆盖厚度以23.0~23.5 cm为宜,即下层施用2.5~3.0 cm的麦灰作为增温层,上层以20.0~21.0 cm的砻糠作为保温层,竹林土壤可保持较高的温度,竹笋产量较高;在覆盖材料的施用方法上,以麦灰2次施入为好,第2次施入麦灰后覆盖上砻糠,可延长出笋期,而且有利于地表温度的平稳变化和提高雷竹笋产量。

| Abstract: | Phyllostachys violascens is an excellent shoot production bamboo species. Mulching technique significantly increases its economic benefits. With experiments, the paper studied the effects of amount and method in use of wheat ash and rice chaff as a new mulching materials on soil temperature and shoot yields. The results showed that when the depth of mulching was properly at 23.0~23.5 cm, i. e., 2.5~3.0 cm at the lower layer with wheat ash as heat generating layer and the top layer deep at 20.0~23.5cm of rice chaff as warm-keeping layer, the soil in the forest could keep at relatively high temperature and the bamboo shoot could achieve a high yield; As for the application of mulching materials, it was concluded that wheat ash would be better to be applied twice, and after the 2 nd application, rice chaff could be mulched, which could extend the period of shooting and also benefit for keeping the stable surface temperature and increasing shoot yield. |
