- Title:
- Growth Status of Hemarthria compressa and Its Influence on Soil Nutrients
- Keywords:
- Hemarthria compressa; growth status; soil pH value; soil nutrients
- 分类号:
- S154.4;S153.6
- 摘要:
- 通过对扁穗牛鞭草在不施肥条件下的生物量、生长因子以及对土壤pH值、有机质、全量元素、水解N、有效P和速效K等测定,了解生长状况及其对土壤养分的影响.结果表明:随着时间增加,生物量显著降低,年均下降50.1%.株高和茎粗表现不同程度的下降,茎长有升有降.而密度增加,年均上升13.7%.土壤pH略有下降,表层土壤有机质、全量元素、水解N、有效P和速效K均表现不同程度的降低,其中水解N、有效P和速效K等土壤有效养分降幅明显,年均分别下降26.73%,23.71%和7.31%,引起地力衰退,供肥力降低,导致生产力下降.
- Abstract:
- A research into growth status of Hemarthria compressa and its influence on soil nutrients was performed through the measured data of biomass,growth factors,soil pH value,soil organic matter,total N,P,K,hydrolysable N,available P and K without fertilizing the experimental fields in Sichuan Agricultural University from 2004 to 2005.The results indicated that the biomass reduced greatly(50.41% per year) with the pass of time and the growth of height and diameter decreased in a certain degree whereas the plant density increased by 13.74% per year and that the soil pH value lowered slightly and soil organic matter,dissolved N,available P and K decreased in various degrees.Among them,hydrolysable N,available P and K decreased 26.73%,23.71% and 7.31% respectively each year,but the bottom layer of soil was not obviously affected by them.The ability of soil fertility supplying declined,which affected productivity of Hemarthria compressa growth directly.
