我们在生产实践中发现毛竹与泡桐混交造林,可以达到桐茂竹荣速生丰产的效果。其原因:①毛竹鞭根多分布于20～40厘米的土层中,泡桐的吸收根主要分布在40～200厘米的土层中,两者吸收矿质营养和水分的垂直范围能错开;②泡桐叶大,树冠大而丰厚,蒸腾量大,夏天可把大量的 We found in the production practice of mixed bamboo and Paulownia afforestation, you can achieve Tongmao bamboo wing fast-growing yield results. The reasons are as follows: 1) The rhizomes of Phyllostachys pubescens are mostly distributed in the soil layers of 20-40 cm, the absorption roots of paulownia are mainly distributed in the soil layers of 40-200 cm, and the vertical ranges of the absorption of mineral nutrients and water can be staggered; Large leaves, crown large and generous, large amount of transpiration, the summer can be a lot of
