摘要
在雷竹竹鞭笋芽分化期（８月至翌年４月）用恒重法、伯川法和双缩脲法对雷竹竹鞭的含水量、糖类和蛋白质含量进行测定。结果表明，幼龄鞭含水量依次高于壮龄鞭、老龄鞭，其中以８～９月笋芽分化期含水最为丰富。蛋白质和碳水化合物等营养物质在８～９月含量很低，而后逐渐升高，在笋期（３～４月）下降至最低点。这种变化关系和竹鞭的发育及笋芽的分化消耗营养物质相关。营养分析表明，８～９月做好肥水管理，以满足行鞭和笋芽分化的养分需求，对提高笋芽分化率有重要意义。
The moisture content,carbohydrates and protein contents of Lei bamboo rhizome during the period of the mixed bud differentiation were measured by use of constant weight,colorimetric method and biuret method.The results showed that moisture content of young rhizome was higher in turn than sound and older rhizome,and moisture content was the most aboundant during August and September,while in this period proteins and carbohydrates were the lowest,and then gradually increased,and then decreased with the growth of bamboo shoot and at last reached the lowest point in March and April of next year.The analysis indicated that the variation had relation with nutrient consumpation during rhizome development and mixed bud differentiation.According to the analysis of nutrient states it was important to improve bud differentiation rates that fertilizer and moisture management was well done to meet the nutrient needs of rhizome growing and bud differentiation.
