摘要
在贵州台江、江西安远、福建明溪及广西宁明设置马尾松造林地不同整地规格试验林。对试验资料的初步分析表明 ,马尾松造林地整地规格与母岩和土壤质地之间存在较为密切的相关关系。因此 ,在确定造林地整地规格时 ,应考虑母岩种类和土壤的质地状况。在我国南方山区 ,马尾松人工造林采用块状整地方式时 ,在母岩为板岩及变质砂岩 ,土壤质地为壤质粘土的地区 ,整地的规格以 40cm× 40cm× 2 5cm的中穴为宜 ;在母岩为花岗岩和石英砂岩 ,土壤质地为砂质粘壤土的地区 ,造林地整地采用 30cm× 30cm× 2 0cm以下的小穴即可。表 4参 1
Experiment stands of different size of planting hole for masson pine were established in Guizhou,Jiangxi,Fujian and Guangxi Province.The results of preliminary analysis to the experiment data showed that there was rather close correlation between size of planting hole and parent rocks and soil textures.When sizes of plating hole were decided,the parent rocks and soil textures should be considered.In mountainous districts of south China,when spot soil preparation was adopted,planting hole of 40 cm×40 cm×25 cm was appropriate for masson pine plantation in the area where the parent rocks were slate and metamorphic malmstone,and the soil texture was loamy clay.The hole of 30 cm×30 cm×20 cm was appropriate in the area where the parent rocks were granite and quartz sandstone,and the soil texture was sandy clay loam.
