近几年,围场县大力开展沙棘造林,摸索出一些造林经验,可归纳为以下三种模式。一、护坡护堤造林模式利用沙棘根系发达、萌蘖性强的特点,营造护坡林或护岸林,保护和固持土壤。营造护坡林,可采用株行距1×1米、1×1.5米、1.5×2米,营造护堤林可采用株行距0.5×1米或1×1米,结合工程措施,与乔木树种混交,效果会更好。棋盘山镇西河两岸提坝,内侧由石块砌成护坡,1988年在外侧栽植沙棘,
In recent years, vigorously carry out the seabuckthorn afforestation, to explore some afforestation experience can be summarized into the following three modes. First, slope protection berm afforestation mode Seabuckthorn roots developed, strong sprouting characteristics, to create a slope protection forest or shore protection forest, to protect and retain the soil. To create a slope protection forest, the row spacing of 1 × 1m, 1 × 1.5m and 1.5 × 2m can be adopted. For the construction of embankment forest, the row spacing of 0.5 × 1m or 1 × 1m can be used. Combined with engineering measures, The effect will be better. Qipanshan town west bank of the river to mention the dam, the inside is made of stone masonry slope, in 1988, planting seabuckthorn on the outside,
