    水土保持植物类芦对氮磷钾养分水平的响应

    Effects of nitrogen, phosphorus and potassium levels on the growth of Neyraudia reynaudiana of soil and water conservation plant

      摘要
    • 摘要:
      目的 探索不同氮磷钾水平对类芦Neyraudia reynaudiana生长状况的影响.
      方法 采用营养液砂培试验，对优良水土保持植物类芦在不同氮、磷和钾供应水平下的响应规律进行了研究.
      结果和结论 0.750 mmol·L-1的氮和0.030 mmol·L-1的钾会显著影响类芦生长，降低类芦地上部和地下部生物量；低磷(0.005 mmol·L-1)对类芦地上部生物量无显著影响，但会显著降低地下部生物量；低磷和低钾(0.030 mmol·L-1)对类芦生长的影响显著小于0.750 mmol·L-1氮水平的影响，在低磷和低钾条件下，类芦根系长度和根表面积显著增加，表现出对低磷和低钾胁迫较强的适应和自我调节能力.用类芦进行植被恢复时，氮素的补充更为重要.

       

      Abstract:
      Objective To explore the effects of nitrogen, phosphorus and potassium levels on the growth of burmareed, Neyraudia reynaudiana.
      Method Nutrient solution-sand culture experiment was applied to study the response of burmareed which was a very excellent soil and water conservation plant at different nitrogen, phosphorus and potassium levels.
      Result and conclusion The results indicated that 0.750 mmol·L-1 N and 0.030 mmol·L-1 K significantly affected the burmareed growth and reduced the aboveground and underground biomass of burmareed. The concentration of 0.005 mmol·L-1 P did not affect the aboveground biomass, but significantly reduced the underground biomass. The effect of 0.750 mmol·L-1 N on the growth of burmareed was significantly stronger than that of 0.030 mmol·L-1 P and 0.030 mmol·L-1 K. In low P and K condition, burmareed could increase root length and surface area, which displayed its strong capacity of adapting and self-adjusting for low P and K stress. Supplement of nitrogen is very important for revegetation with burmareed.
