美国红枫林下种植油用牡丹试验初报

本文对美国红枫林下种植油用牡丹的形态及产量相关指标进行了研究,结果表明,美国红枫套种油用牡丹对其冠径生长的影响不大；其余指标与乔木距离远近有一定的起伏,大多指标在离乔木200cm-280cm范围内有较高的水平,单株结果量低于对照50%、种子数量低于对照50%,种子的百粒重高于对照90%,单株产量和果荚角数与对照组差异不大。本试验初步结果也表明：美国红枫是一类比较适宜与油用牡丹套种的上层落叶乔木,且离乔木200cm-280cm范围内,比其他位置套种的油用牡丹的生长及产量更具优势。

Preliminary Report On Planting Oil Peony Under American Red Maple ForestBian Yawen Wujin Branch station of Changzhou Forestry Workstation

This paper studied the morphology and yield-related indexes of oil peony planted under American red maple forest. The results showed that American red maple interplanting oil peony has little effect on the crown diameter growth; the distance between other indexes and the tree has certain distances. Ups and downs, most of the indicators have a higher level within the range of 200cm-280cm from the tree, the yield per plant is 50% lower than the control, the number of seeds is 50% lower than the control, the 100-seed weight of the seeds is higher than the control 90%, and the yield per plant There was little difference in the number of angles of the pod and the control group. The preliminary results of this experiment also show that American red maple is a kind of upper deciduous tree that is more suitable for interplanting with oil peony, and within the range of 200cm-280cm from the tree, it has more advantages in growth and yield than oil peony interplanted in other locations.
