砍伐毛竹后留在林地的伐桩、鞭根错结,坚如块石,经久不腐。如不加处理会导致伐桩充塞林地,阻碍竹鞭生长,缩小林地有效生产面积,影响产量。用人工挖掘,虽有取得薪材之利,但费时费力。如何方便有效地清除和利用伐桩引起了不少研究者的兴趣。1978年裘福庚等利用示踪原子法发现毛竹腔壁对可溶性有机物和无机盐类溶液有很大的吸收能力,指出了利用竹腔施肥的前景。其后张雨生等在广西桂林,石全太等在浙江安吉开展了较大面积
After cutting bamboo leaves in the wood after the stake, whip root knot wrong, as hard as stone, endure rot. If untreated will lead to deforestation stuffed woodland, hinder the growth of rhizomes, reduce the effective production area of woodland, affecting the yield. Excavation by hand, although made fuelwood Lee, but time-consuming and laborious. How to conveniently and effectively remove and use the felling has aroused the interest of many researchers. In 1978, Qiu Fageng and other tracer atomic method found that the bamboo wall of soluble organic matter and inorganic salts solution has a great ability to absorb, pointed out that the use of bamboo fertilization prospects. Later, Zhang Yunsheng and other Guilin in Guangxi, Shi Quantai in Zhejiang Anji carried out a larger area
