不同地被植物对土壤养分含量和土壤酶活性的影响
|
摘要
地被植物具有改土培肥能力,但其效果因品种而异。试验选取海南三亚园林绿化常用的地被植物地毯草(Axonopus compressus)、蔓花生(Arachis duranensis)、结缕草(Zoysia japonica Steud)、蟛蜞菊(Wedelia chinensis),以自然生草与清耕作为对照,对比分析了不同地被植物对土壤养分和土壤酶活性的影响。结果表明,土壤有机质、全氮和碱解氮含量以蟛蜞菊处理最高;土壤全磷、速效磷和速效钾含量均以自然生草处理最高而蟛蜞菊处理最低;土壤全钾含量以地毯草处理最高而自然生草处理最低。土壤蔗糖酶、脲酶和过氧化氢酶活性均以蟛蜞菊处理最高;土壤酸性磷酸酶活性则以自然生草处理最高而蟛蜞菊处理最低。土壤脲酶和过氧化氢酶活性与碱解氮含量极显著正相关(P<0.01),蔗糖酶活性与土壤有机质含量极显著正相关(P<0.01),酸性磷酸酶活性与土壤全磷、速效磷含量显著正相关(P<0.05)而与土壤全氮含量显著负相关(P<0.05)。
Garden cover plants can enrich and improve the soils, but the effect varied from different plant cultivers. The experiment was conducted with four different garden cover plants(Axonopus compressus, Arachis duranensis, Zoysia japonica Steud, Wedelia chinensis) which were widely used in horticulture of Sanya city, Hainan province, and the natural grass and clean tillage were as control,to analyze the different garden cover plants on soil nutrient contents and enzyme activities. The results showed that in all the six treatments, soil organic matter, total nitrogen and alkali-hydrolyzed nitrogen content were highest in the W. chinensis treatment; soil total phosphorus, available phosphorus and available potassium content were highest in natural grass treatment but lowest in W. chinensis treatment; soil total potassium content was highest in A. compressus treatment but lowest in natural grass treatment. The activity of soil invertase, soil urease and soil catalase were highest in W. chinensis treatment, and the activity of soil acid phosphatase was highest in natural grass field but lowest in W. chinensis treatment. The activity of soil urease and catalase had significantly positive correlation with the soil alkali-hydrolyzale nitrogen content(P<0.01), the activity of soil invertase had significantly positive correlation with soil organic matter content(P<0.01), the activity of soil acid phosphatase had significant positive correlation with soil available phosphorus content(P<0.05) but significant negative correlation with soil total nitrogen content(P<0.05).
