为了研究毛竹林松土施肥的增产潜力、使用不同种类肥料对林地土壤改良的影响和长期使用化肥后土壤性质是否变劣等问题,特进行了调查,现将结果作一报导。根据毛竹林松土施肥的类型和立地条件等,将地理位置相邻近的标准地两两配对,分作四个区组,即劈山不松土施肥与松土少施化肥;松土施化肥与松土施有机肥;松土少施化肥与松土常施化肥;劈山不松土施肥与松土施 In order to study the yield-increasing potential of the soil fertility of Phyllostachys heterocycla cv. Pubescens, the effects of using different types of fertilizers on soil improvement and the deterioration of soil properties after long-term use of fertilizers were investigated. The results are reported as follows. According to the type and site conditions of soil fertilization and so on, the standard adjacent plots of geography are divided into four blocks, that is, And organic fertilizer application of loose soil; soil less fertilizers and loose fertilizers frequently applied fertilizers;
