辽宁西部地区气候干燥,水土流失严重,山地土质瘠薄,造林树种较为单纯。为了丰富造林和水土保持树种,我站从1959年开始引种沙棘,已获得成功。引种试验证明,沙棘是一种良好的防风、固沙、保持水土的灌木或小乔木。它既耐干旱又耐水湿;不择土质,黄土、红土、砂土、粘土都能生长;适应范围很广,山顶部、阴坡、阳坡、沟谷都能适应;生长比较迅速,根蘖萌生力强,根系特别发达。现已成为我省西部造林的先锋树种。为了发展这一优良树种,现将几年来引种沙棘的育苗、造林体会整理如下,以供参考。
The climate in western Liaoning is dry with severe soil erosion and poor soil quality in mountainous areas. The afforestation tree species is rather simple. In order to enrich afforestation and soil and water conservation tree species, I started to introduce seabuckthorn plants in 1959 and have succeeded. Introduction test shows that seabuckthorn is a good windbreak, sand, water and soil to maintain the shrubs or small trees. It is both drought-resistant and water-resistant. Soil-free, loess, laterite, sand and clay can all grow. Adaptation to a wide range of tops, shades, sunny slopes, valleys can adapt to the rapid growth of root tillering Strong, particularly developed roots. Has now become the pioneering tree plantation in the western part of our province. In order to develop this excellent tree species, now introduced seabuckthorn breeding seedlings in recent years, afforestation experience organized as follows, for reference.
