杉苗移植成活力初步研究

通过对杉苗出圃定植过程苗木失水、剪根与发根关系的试验分析表明：杉苗水分是定植成活的要素；苗根中１－２ｍｍ粗根对发根最重要；细根失水较快，长途运输杉苗宜剪去部分细根；杉苗失水率在３５％以下可以发根。

A Preliminary Research on the survival Power of Cunninghamia lanceolata Seedlings Transplanted

The experimental analyses of the relationships among losing water, cutting roots.and developing roots of Cunning hamia lanceolata seedlings from a nursery and in field pfanting in-dicate that the water of seedlings is the essential factor of the survival of field planting; the 1 2mm of thick roots in seedling roots are most important for the development of roots; fine roots lose the water faster and therefore we should cut part of the fine roots when we conduct the long-distance transport of C. lanceolata seedlings; and C. lanceolata seedlings can develop roots when their water los8 rate is below 35%.
