摘要
该文研究了不同集流措施对黄土高原坡面生长的林木组织水势、光合色素含量及净光合速率以及对刺槐幼树高、径和树冠生长的影响。结果表明，拍光林地坡面及在拍光坡面喷涂有机硅防止雨水下渗的集水措施对改善林地土壤及林木水分状况、促进林木代谢活动、加速林木的生长是有效的。
The effects of catchment methods on water potential,photosynthetic rate,chlorophyll content and growth of trees planted in sloping fields were studied in loess plateauof Shanxi povince,ResuIts indicated that the water conditions of soil and tree tissues wereimproved by catchment of making slopes bare and smooth as well as using organic silicon toprevent water loss, and as a result the trees planted in the catchment sloping fields can growfaster than those planted in nature slopes.Those methods may be effective for tree plantingin dry mountain area.
