毛竹专用矿渣肥施用技术研究

Study on Fertilization Technology of Special Slag Fertilizer for Phyllostachys edulis

对江西靖安太平洲毛竹林进行毛竹专用矿渣肥不同施肥时间、施肥量和施肥方式的研究,结果表明:各因素对毛竹新竹胸径、枝下高、成竹数影响大小的顺序依次为:施肥量>施肥时间>施肥方式。根据试验得出矿渣肥影响毛竹胸径生长3因素的最优水平依次为:笋前施肥、45%矿渣肥8 kg、株施;影响毛竹枝下高生长3因素的最优水平依次为:笋前施肥、45%矿渣肥12 kg、株施;影响毛竹成竹数3因素的最优水平依次为:笋后施肥、45%矿渣肥12 kg、株施。

The different time,amount and ways of fertilization of special slag fertilizer for Phyllostachys edulis in bamboo forests in Taipinzhou of Jing an County,Jiangxi Province were analyzed.The results showed that the sequence of affect from various factors on bamboo diameter,canopy height,bamboo emerging number was as follows:fertilization >fertilization time> fertilization ways.It was obtained under the test,the optimal level of 3 factors that slag fertilizer affect the growth of Ph.edulis diameter at br...
