自1985年以来,丰润县共营造水保林10万亩,为提高造林成活率,确保造林成果,我们试验、示范和推广了一系列技术措施,并取得了较好效果。一、雨季造林。干旱山区造林成活率低的主要原因是缺水。雨季造林水分充足,造林地墒情好,林木成活率高。二、提前整地。把临时整地改为提前一年或雨季前整地。整地方式有反坡梯田、水平沟、水平阶、水簸箕,连环水窖和鱼鳞坑等7种。其中反坡梯田整地能截坡面径流95%以上,效果最好,采用这种
Since 1985, Fengrun County has built a total of 100,000 mu of Shui Lin Lin. To improve the survival rate of afforestation and ensure afforestation achievements, we experimented, demonstrated and promoted a series of technical measures and achieved good results. First, the rainy season afforestation. The main reason for the low afforestation survival rate in arid mountainous areas is lack of water. Rainy season sufficient afforestation, afforestation soil moisture, forest survival rate. Second, advance preparation. The temporary land preparation changed to one year in advance or before the rainy season. Land preparation methods are terraced fields, horizontal ditch, horizontal steps, waterpan, chain cellar and fish scale pit 7 kinds. Among them, the anti-slope terraces land preparation can achieve a surface runoff of over 95% with the best results
