几种覆盖材料对雷竹林地土壤增温效果研究

Temperature Increase Effect of Several Mulching Materials on Phyllostachys praecox Forest Soil

以稻草和砻糠作为雷竹林地覆盖基础层,遵循保温、透气、保湿、环保、经济、易得等原则,选择鸡粪、麦麸、菜饼等作为添加覆盖材料,进行雷竹林地覆盖增温效果试验。结果显示:在基础覆盖层间加入鸡粪(750t/667 m2)+麦麸(500 t/667 m2)+菜饼(750 t/667 m2)的配方效果最佳,最有利于林地增温和保温。

Mulching for temperature increase on Phyllostachys praecox forest land was experimented with straw and rice chaff as the base layer of the mulching and fowl dung, wheat bran and vegetable cake as added materials, which were chosen by following the principles of temperature maintenance, ventilation, moisture maintenance, environmental-friendliness, economy, and easy to access. The results showed that adding of fowl dung （750 t/667 m2） ＋ wheat bran （500 t/667 m2） ＋ vegetable cake （750 t/667 m2） between the base layers was the formula with the best effect in terms of land temperature maintenance and increase in the forest.
