摘要
为探究不同平茬高度对杂交桑树苗木生长的影响,以一年生杂交桑为研究对象,进行了5 cm和10cm两种高度的平茬试验。结果表明:留茬5 cm的桑树叶片数、枝条数、叶片重、杆重和总鲜重高于10 cm组;叶片和枝条含水率低于10 cm组,但均无显著差异。5 cm与10 cm的平茬高度对植株生长没有显著影响,为了获得更大的经济效益和生产效益,推荐杂交桑树的适宜平茬高度为5 cm。
In order to explore the effects of different stubble heights on the seedling growth of hybrid mulberry,one-year-old hybrid mulberry was used as the research object and the flat stubble height was set as 5 cm and 10 cm.The results showed that the number of leaves and branches,leaf weight,stem weight and total fresh weight of mulberry with 5-cm stubble were higher than those with 10-cm stubble,and the water content of leaves and branches were lower than those of 10-cm group,but there was no significant difference.The stubble height of 5-cm and 10-cm had no significant differences on plant growth.In order to obtain greater economic and production benefits,we recommend that the suitable stubble height of mulberry was 5 cm.
