厚朴林下轮作玄参、大黄种植技术研究

为更好地指导厚朴规范化种植,充分利用土地资源,大力发展林下经济,增加农民收入。2002年,在龙坪乡开展了厚朴林下轮作玄参、大黄种植模式和厚朴单作种植模式对比试验研究。试验结果表明:在厚朴林下轮作玄参、大黄种植模式下,厚朴各测树因子及皮产量较对照具有明显地增长和增产作用,同时每个轮作期内比对照增产大黄药材520 kg/666.7 m2、玄参药材320 kg/666.7 m2。

Study on the Magnolia officinalis Undergrowth Rotation Rheum offcinale and Scrophu ningpoensis Planting Technology

This study was carried out with the purpose of guiding the Magnolia officinalis standardized planting,making full use of land resources,developing the forest economy greatly,and increasing farmers’ income.In 2002,the Magnolia officinalis understory rotation Scrophu ningpoensis,Rheum offcinale planting patterns and Magnolia monoculture planting pattern comparison research was made in the town of Long Ping.The results showed that under rotation mode of Magnolia officinalis with undergrowth Rheum offcinale or Scrophu ningpoensis,the principal measurement factors of Magnolia officinalis and bark yield increased obviously compared with that of control.During each rotation period the yield of Scrophu ningpoensis and Rheum offcinale herbs increased by 520kg/666.7m^2,320kg/666.7m^2 respectively.
