摘要
利用日光温室夏季空闲期,研究了草菇(夏季填闲)-黄瓜(秋冬茬)轮作栽培对土壤理化性状的影响。结果表明,草菇-黄瓜轮作栽培可以有效优化根际环境,协调土、肥、水、气环境,促进黄瓜植株生长,轮作可以有效提高土壤肥力,增加土壤有机质和氮磷钾元素的含量;轮作可以缓解土壤板结,降低土壤容重,疏松土壤;轮作有效改良了土壤结构,促进了土壤团聚体结构的形成,提高了土壤团粒结构占比,改善了土壤颗粒通气透水性;轮作提高了土壤酶活性,缓解了土壤酸化,调节土壤酸碱平衡。因此,草菇-黄瓜轮作制度可以充分利用温室空闲期,缓解土壤连作障碍,提高土壤质量,是一种高效的生态循环种植模式。
The present study assessed the effect of rotation of Volvaria volvacea(leisure stage during summer)-cucumber(autumn-winter cultivation)on soil physicochemical property in solar greenhouse production.The result showed that rotation of Volvaria volvacea-cucumber improved rhizosphere microenvironment by regulating soil,fertility,moisture and gas.Rotation efficiently improving soil fertility by increasing the content of soil organic matter,nitrogen,phosphate and potassium;rotation moderated soil hardening by decreasing soil bulk density and modifying soil structure;rotation modified soil structure and increased the percentage of macro-aggregate,which promoted the formation of macro-aggregate and improved water-gas transport capacity;rotation improved soil enzyme activity and moderated the soil acidification.Thereby,rotation of Volvaria volvacea-cucumber efficiently utilized the leisure stage during summer and moderated soil obstacle of continuous cropping by improving soil quality.In conclusion,rotation of Volvaria volvacea-cucumber was an ecological and recycle greenhouse cultivation.
