Study on the Recover Effect of Remedial Measures on Moso Bamboo Stands after Frost and Snow Disaster

The effects of remedial measures on moso bamboo stands after frost and snow disaster were studied. The investigated spots were in Huangshan County in Anhui Province where the bamboo was destroyed severely in this disaster. It was shown that the effects produced by remedial measures were different for different damaged styles and degrees. (1) For the moderately bended bamboo, the effect of topmost branches cut was not evident, but for the heavily bended ones, the effect was obvious. (2) For the cracked bamboo, the remedial measure was cutting most culm and top branches at the broken spot. When the cracked degree was moderate, the remedial measure had a greater effect on the surviving bamboo growing than surviving rate, and the ratio of bamboo growing well had increased from 11.1% to 44.4%. However, when the cracked degree was heavy, the cutting measure had a bad effect. (3) For the rhizome-upturned bamboo, when the rhizome-upturned degree was moderate, almost all could survive, but the remedial measure—soil-covering could do good to the growing. And for the heavily rhizome-upturned ones, the surviving rate was only 50%, and soil-covering remedy had an effect on both surviving and growing.
