摘要
以银中杨、河北杨、新疆杨、中林46杨、白腊、毛白杨大苗在宁夏引黄灌区惠农区的农田林网区造林,结果表明:银中杨适宜在宁夏灌区农田林网造林,成活率高于其他试验树种;采用200 mg/L ABT生根粉喷根,可以提高银中杨造林成活率10.14%;农沟和农渠均适宜于银中杨造林,二者造林成活率相差不大;在农沟上造林应注意选择地势高、排水通畅、含盐量低于4‰地段。
Through planting P. alba x P. berolinensis, P. hopeiensis, P. alba var. pyramidalis, P. tomentosa in Huinong district in Ningxia irrigating area, the results show P. alba × P. berolinensis is suitable to be planted in this area with the survival rate higher than other experimental tree species. The survival rate of P. alba × P. berolinensis can be risen by 10.14% with spraying 200 mg/L rooting powder （ABT）. P. alba × P. berolinensis can be planted in field canals and field ditches with less difference on survival rate. Forestation in field canals should choose the higher place with smooth drainage and salt content lower than 4‰.
