植地坡向、坡位和整地方法对苦楝早期生长的影响

         

摘要

采用随机区组调查法对闽东北2g-山地种植区的苦楝与不同坡向、坡位和整地方法的生长量关系进行研究.结果表明,不同坡向、坡位和整地方法2年苦楝造林的平均存活率77.1%~95.1%、平均树高0.71~4.17m、平均地径1.83~7.21cm。种植苦楝的坡向、坡位应选择阳坡、下部为宜,阴坡、上部则会影响其生长量。整地方法应选择挖大穴,坡改梯整地会引起水土流失而破坏生态环境造成苦楝存活率较低和生长不良。%The randomized to survey method to northeast 2a mountain fujian region Melia azedaraeh and the different planted slope, slope position and soil preparation methods of a relationship between growth. The results show that, the different planted slope, slope position and soil preparation methods 2a Melia azedaraeh afforestation survival rates an average of 77.1% - 95.1%, the average tree height of 0.71 - 4.17m, average ground diameter 1.83 - 7.21em. Melia azedaraeh planting the slope to, slope a should choose a sun, and at the bottom advisable, Yin slope, the upper will affect its growth. Soil preparation methods should ehoose to dig the big holes, established can eause soil and water loss and soil preparation damage the eeologieal environment eaused by the Melia azedaraeh lower survival and growth is poor.
