西南桦配比施肥试验
The Proportioning Fertilization Experiment on Betula alnoides
[目的]为探索西南桦人工纯林最佳生长量,于福建省华安县金山林场万世清工区开展西南桦人工纯林施肥试验。[结果]氮肥试验各种处理对无性系 1、2、3的树高、胸径、材积均无显著差异或极显著差异;但氮肥试验对无性系 4的树高、胸径、材积有显著差异或极显著差异:处理 5为最优选择。不同氮肥处理,在有机质、全N、全P、全K、碱解N、有效P、速效K、活性Al的变化方面,各处理之间均没有显著差异或极显著差异。在pH值、有效Mg方面,仅第 4处理与其它处理有显著差…查看全部>>
