毛竹增产剂施肥对比试验初探

Study on Comparative Trials of Phyllostachys edulis by Applying Agents for Increasing Production

对第二年为春笋大年和春笋小年的毛竹林,分别开展施毛竹增产剂、毛竹专用肥、不施肥的对比试验。研究其对第二年春笋各项因子(出笋数、笋大小、退笋数、早期笋等)的影响。结果表明,施毛竹增产剂能有效提高第二年为春笋大年毛竹林的发笋数,而且能明显地提早发笋,增加早期笋的数量。但对第二年为春笋小年的毛竹林的发笋数没有明显的作用。

The author conducts three comparative trials of Phyllostachys edulis forest by applying agents for increasing production, exclusive fertilizer Phyllostachys edulis or none. The results are as follows： For trial Phyllostachys edulis forest whose potential yield quantity is huge the next year, the quantity of spring bamboo shoots remarkably increases and grows in advance the next year, whereas there is no substantial change for Phyllostachys edulis forest whose yield year is off year.
