毛竹林大小年现象分明,每二年约有六个月的竹叶发黄、脱落、换新小叶时间,这期间竹林光能利用效率不高,严重影响次年的产量。通过小年留笋养竹、大年疏笋、控制新竹数量,并采取切断部分立竹的支鞭,利用竹子生长顶端优势,多发叉鞭,造成大小年立竹的多鞭系统竹林结构,同时结合松土、施肥,改善土壤理化性质,提高竹林光能利用率,使每年都有出笋成竹,其产量可比大小年分明的竹林增产20～30％。
Bamboo forest annual size is clear, about every six years about six months of yellow leaves, shedding, for a new leaflet time, bamboo light utilization efficiency during this period is not high, seriously affecting the next year’s output. Bamboo shoots through the small year, bamboo shoots, controlling the number of Hsinchu, bamboo branches and take some cut off the whip, the use of the top advantages of bamboo growth, multiple cross whip, resulting in the size of the bamboo system whip whip bamboo system, at the same time Combining with loosening and fertilizing to improve the physical and chemical properties of the soil and improve the utilization rate of light energy in bamboo forests, the bamboo shoots are produced every year. The yield of bamboo can be increased by 20% to 30% than that of bamboo forests of different sizes.
