Effect of bio-colloidal slow-release fertilizer on the increment of orc-hid shoots/Wang Guo-liang* et al//Journal of Jiangsu Forestry Science & Technology.-1990, 17 (2) .-17-20,22

本文用生物胶作载体,加1250ppm、2500ppm、5000ppm营养液分别配制成生物胶缓释肥,分别施于洋兰试管苗的生长基质中,用叶面积模型Y=-0.32+0.87X(X=1.d)定期测算叶面积增量,以研究生物胶缓释肥对洋兰生长量的影响.运用模糊正交设计分析表明,在施肥方法、营养液浓度和施加次数3个试验因子中,施肥方式是影响生长的主要因子.与直接施加营养液的传统施肥方法相比,生物胶2号缓释肥能有效地促进洋兰试管苗的生长,其平均叶面积生长量提高2倍以上,且肥效持续时间长,成本低廉,具有较高的实用价值.
