蔬菜不同轮作方式对温室甜瓜产量及根区土壤酶活性的影响

摘要

In order to establish the reasonable muskmelon rotation system ,taking melon cultivar Chuntian 3 ,to-mato cultivar Dongnong 709 ,bean cultivar August Green ,celery cultivar Solid Celery and onion cultivar Chang-bai as test varieties ,ridge culture method(celery with bedding and sowing )was adopted in the greenhouse ,the effect of crop rotation on the yield and soil enzyme activities of the melon in the root zone was studied .The re-sults showed that soil urease activity and yield of muckmelon was significantly higher than other treatments on the crop cultivation of celery in front of the melon (P< 0 .05);soil dehydrogenase activity was significantly higher than other treatments in celery and other vegetables rotation(P<0 .05);soil neutral phosphatase activity was significantly higher than others (P<0 .05) .So that the celery crop rotation improve of melon production and soil environment had better effect than other .%为建立合理的甜瓜轮作体系，以甜瓜春甜三号、番茄东农709、菜豆八月绿、芹菜实心芹以及长白大葱为供试品种，在温室中采取垄作（芹菜采用平畦撒播方法）方式，研究设施栽培中番茄、菜豆、芹菜、大葱与甜瓜轮作，对甜瓜的产量及根区土壤酶活性的影响。结果表明：在甜瓜前茬种植芹菜时土壤脲酶活性显著高于其它处理（P＜0．05）；在芹菜与其它蔬菜轮作后种甜瓜的处理中，甜瓜根区土壤脱氢酶活性显著高于其它处理（P＜0．05）；在菜豆与芹菜轮作后种甜瓜的处理中，甜瓜根区土壤中性磷酸酶活性及甜瓜产量显著高于其它处理（P＜0．05）。因此说明与其它轮作方式相比，芹菜轮作对提高甜瓜产量和改善土壤环境有较好的作用。
