| 摘 要： | 通过施肥试验对胡枝子苗木生长及嫩枝叶产量的影响进行分析.结果表明:在胡枝子的生长及产量方面,施肥比未施肥的效果显著;磷酸二铵和硫酸钾平衡施肥的效果显著好于单施磷酸二铵;8号处理(磷酸二铵10 g+硫酸钾10 g)在株高、地径和嫩枝叶干质量产量最大分别为169.947、1.113 cm,5 209.40 kg/hm2,比对照增加20.88%、28.37%、156.30%;通过经济效益分析,表明使用4号处理(磷酸二铵5 g+硫酸钾5 g)时增收最明显,净增收为1 000.44元/hm2.

| Abstract: | A fertilization experiment was conducted to study the growth of seedlings of Lespedeza bicolor and the yield of tender branches and leaves.Results showed that fertilization could significantly increase the growth increment of seedlings and the yield of tender branches and leaves of L.bicolor compared with non-fertilization.The effect of balanced fertilization with(NH4)2HPO4 and K2SO4 was obviously better than that of fertilization with only(NH4)2HPO4.The height,basal diameter and dry weight of tender branch... |
