毛竹林松土施肥有显著的增产效果,但受到地形条件的限制。为防止水土流失,坡度在25°以上的竹山,一般不宜松土,施肥亦很难进行。在浙江,陡坡竹林占竹林总面积的三分之二;另外,松土施肥费工,成本高。这样就有必要寻找简便而有效的施肥方法。我们于1982年和1984年在安吉县重复进行了二次毛竹根外施肥试验,取得了比较好的效果。
Maozhulin loosening fertilization has a significant yield increase, but by the terrain conditions. In order to prevent soil erosion, bamboo hills with a slope above 25 ° are generally not suitable for loosening soil and fertilizers are very difficult to carry out. In Zhejiang, steep slopes of bamboo forests account for two-thirds of the total area of bamboo forests. In addition, soil fertilization and labor costs are high. This makes it necessary to find a simple and effective method of fertilization. In 1982 and 1984 in Anji County, we repeated the second bamboo root fertilization test, and achieved good results.
