环保基质对佛甲草草毯生长及其结构稳定性的影响

于湖南省植物园内集中收集的枯枝、落叶经过破碎、调制、发酵、干燥、粉碎、包装等工艺生产出适合于佛甲草草毯的专用基质,研究该基质对佛甲草草毯生长及其结构稳定性的影响。结果表明:自制环保基质可完全替代泥炭土,佛甲草草毯生产的综合成本下降50%以上;平均成坪速度提高1~2倍;佛甲草草毯基质适宜厚度为1-3 cm,最佳组合比例为50%基质+50%种植土(体积比)。

Effect of environmental substrate on the growth of Sedum lineare turf and its structural stability

Deadwood and fallen leaves which collected from Hunan Forest Botanic Garden through a series of process of crushing,stirring,fermenting,drying,smashing and packing to produce special substrates for Sedum lineare turf,the effect of special substrates on the growth of Sedum lineare turf and its structural stability was studied. The results showed that,these substrates were proved that can perfectly substitute peat moss,keep total costs down above 50%on Sedum lin-eare turf production,and meanwhile the average speed in covering improved one or two times . The suitable height of substrates in Sedum lineare turf was 1 -3 cm,and the optimal proportion was 50% substrates with 50% planting soil （volume ratio）.
