魔芋种植对两种梨树林土壤酶活性的影响

Effects of Konjac Planting on Soil Enzyme Activity of two Kinds of Pear Plantations

  • 摘要: 为研究魔芋种植对两种梨树林下土壤酶活性的影响,本试验以未种植魔芋梨树林地作为对照,研究了不同林地的土壤脲酶、蔗糖酶和磷酸酶活性。结果表明,种植魔芋对丰水梨林下土壤脲酶和磷酸酶活性的影响不显著,蔗糖酶活性却显著增加;昌吉梨林下土壤磷酸酶和蔗糖酶活性在种植魔芋后变化不显著,脲酶活性则显著下降;昌吉梨林下土壤翻耕后蔗糖酶活性显著下降,脲酶和磷酸酶活性则无明显变化。可以看出,种植魔芋对梨树林地土壤酶活性影响各异,翻耕使得土壤酶活性降低。

     

    Abstract: To study the effects of konjac planting on the soil anzyme activity of two kinds of pear plamtations,taking pear woodland without planting konjac as a control,studies were made of the activity of urease,invertase and phosphatase in soil of different forest lands. The results showed that the effect of planting konjac on the activity of urease and phosphatase in the pear forest soil was not significant,but invertase activity had a significant increase. The phosphatase and invertase activity in Changji pear forest soil after planting konjac did not change significantly,and yet urease activity decreased significantly; invertase activity decreased significantly after plowing Changji pear forest soil,urease and phosphatase activity did not change significantly. As could be seen the effect of konjac planting in pear woodland on soil enzyme activity was not significant. But real tillage would make the soil enzyme activity decrease significantly.
