在“南竹北移”的群众性科学实验运动中,我们自1972年以来,连续作了多次碱性土毛竹种子育苗试验:其中1972年冬和1973年春,分次在半分地上播种495穴,由于经验不足,管理不当,发芽率仅为14％。到1975年春,只保存竹苗42穴;1974年4月初,在1分地上播种383穴,发芽率达80％。到1975年春,保存竹苗192穴。新生幼苗在1—3年内具有高度丛生和多次再生能力。分蘖苗一次比一次高,一年比一年粗。1年生幼苗一般高为21.7
In the mass experiment of science in the movement from south to north, we have successively conducted several experiments of seedling raising of Alkali Muddy Phyllostachys pubescens since 1972: in the winter of 1972 and the spring of 1973, 495 holes , Due to lack of experience, mismanagement, germination rate was only 14%. By the spring of 1975, only 42 bamboo seedlings were preserved. In early April 1974, 383 seeds were sown on the ground of 1 minute and the germination rate reached 80%. To the spring of 1975, save 192 points bamboo seedlings. Newborn seedlings in 1-3 years have a high degree of clustering and multiple regeneration. Tillering seedlings once higher than a year, a year thick. 1-year-old seedlings are generally 21.7 high
