植地坡向和整地时间对楸树引种苗生长的影响

The Influence of Planted Slope and Soil Preparation Time on the Growth of Catalpa bungei Seedlings

采用随机区组调查法探讨闽东北引种试验区1年生楸树苗生长量与不同坡向、不同整地时间的关系,结果表明:不同坡向、不同整地时间1年生楸树造林平均成活率98.2%,平均树高0.97 m,平均地径1.65 cm。种植楸树的坡向应选择南坡为宜,北坡则会影响其生长量;整地时间应选择秋末冬初。

Adopting a random area set survey method, the relationship of annual Catalpa bungei seedlings growth rate and different slope, different soil preparation time in Fujian northeast area was studied. The results showed that annual Catalpa bungei seedlings were the survival rate of 98.2%, the seedling height of 0.97 m and the ground diameter of 1.65 cm. Catalpa bungei seedlings were suitable for growth of south slope, and the seedlings growth would be inhibited at north slope. The soil nreoarafion time would be chosen in late autumn and early winter.
