树皮有机基质对毛竹的施肥效果初探

Preliminary Study on Effects Different Fertilization of Bark Organic Substrate for Bamboo

选用树皮有机基质和两种生物有机肥料对毛竹进行了施肥试验。通过连续2 a的试验观察和测量,结果表明树皮有机基质能提高土壤有机质含量,改善土壤条件,提高土壤肥力,且肥效较长,促进了行鞭育笋,减少退笋,提高了毛竹产量,每亩增加毛竹13株,增加毛竹重量216.1kg,但并没有增大毛竹胸径。与两种有机肥料相比,其增产效果相对较差。

This paper study the effects on different fertilization between bark organic substrate and two kinds of bio-orgartic fertilizer treatments for Moso bamboo.The effects of bark organic substrate fertilization on improving soil organic matter content,changing soil conditions , increasing soil fertility , fertilizer longer ,increasing root and shoot, reducing shoot degeneration, increasing banlboo production, bamboo increased 13 strains per mu and 216.1kg in weight without increased strain diameter studied through 2-year repeat experiment in nursery. Bark organic substrate has worse effects on increasing bamboo production than other two organic fertilizers.
