黄土丘陵区旱年造林技术试验

黄土丘陵区干早年份较常见，春旱尤为严重。在这一地区造林的成效，首先取决于水分条件。在干早年份造林，采取以下技术措施:水平阶和大型鱼鳞坑整地、中耕除草、利用就地坑穴蓄水和浇少量水，地膜覆盖等，可以提高造林的成活率，有利树木的生长。

Preliminary Report on Dry Year Afforestation Technique Experiment in Loess Hilly Region

Dry year is relatively common in loess region, particularly spring drought. The result of afforestation in the region is, first of all,determined by-water condition. The following techniques, such as making field with level ditch and large-size scaly pit, middle-tillage and weed-removing, water storing with existing pit and limited irrigation, and ground film coverage, should be used in dry year afforestation so as to increase tree survival rate and for tree to grow well.
