摘要
本文开展了毛叶木姜子的生长指标和果实含油率与肥料种类的对比试验。试验结果表明:1)施用有机肥料能够大幅提高毛叶木姜子的生长量。树高增加值为对照的215%,胸径增加值为对照的276%,一级侧枝数比对照平均多增加了2.44枝。2)施肥可以提高毛叶木姜子果实的含油率。无论是有机肥还是复合肥,都比未施肥的对照提高果实含油率0.5%以上,其效果十分显著。因此,建议在毛叶木姜子人工林的集约经营生产中提倡多施用有机肥。
A trial of fertilization on Litsea mollis species was conducted at Lingshui County in Sichuan province by a random plot design. The results have shown that： 1 ） the organic fertilizer can greatly increase the increment of Litsea mollis stand. For example, the height of stand is higher by 215 per cent, the diameter breast-high is greater by 276 per cent and the number of the first branch inereases by 2.44 than the control （CK） ; 2） The fertilization can promote the rate of oil deposit by 0. 5 per cent. Therefore, it is suggested that more organic fertilizer should be used in intensive management of Litsea mollis plantations.
