灵芝-蔬菜温室间作栽培对产量的影响及其CO2互补效应

Intercropping Ganoderma lucidum and Vegetable for Improvements on Crop Yield and CO2 Emission

    摘要
  • 摘要:
      目的  探讨菌蔬温室间作下不同食用菌和蔬菜数量配比对其互作效应的影响，为设施菌蔬间作技术研究与应用提供科学依据。
      方法  利用温室控制试验研究了不同灵芝-蔬菜温室间作栽培对蔬菜生长和灵芝碳素转化利用的影响，以及温室内CO2浓度变化差异。
      结果  蔬菜单作模式下温室内CO2浓度日变化较为平缓，菌蔬间作模式下灵芝培养料中的碳素以呼吸消耗的形式排放（占总碳量的51.62%~52.46%），导致温室内CO2浓度夜间处于较高值，白天显著下降。灵芝+蔬菜间作模式灵芝产量比灵芝单作和灵芝（减半量）+蔬菜间作方式分别提高了9.8%和23.6%；生菜和叶用甘薯产量也比蔬菜单作和灵芝（减半量）+蔬菜间作方式有不同程度提高。
      结论  合理的菌蔬间作可提高蔬菜和食用菌的产量，达到增产增效和CO2减排的目的，其中以灵芝-蔬菜间作模式效果较好。

     

    Abstract:
      Objective  Effects of fungi-vegetable intercropping on crop yield and environmental CO2 were studied.
      Method  By intercropping Ganoderma lucidum and vegetables in varied ratios, the plant growth, carbon transformation and CO2 emission were monitored in a confined chamber.
      Result  The daily CO2 emission of vegetable cultivation was relatively constant. But the intercropping induced significant variations. It was heightened at night and declined in daytime as carbon was discharged as CO2 from G. lucidum (accounting for 51.62% to 52.46% of total carbon emission). The fungal yield under the total-and half-G.lucidum intercropping increased by 9.8% and 23.6%, respectively. The intercropping raised the yield of lettuce or leaf sweet potato to different extends.
      Conclusion  By cultivating G. lucidum along with vegetables, crop yields benefitted, and at the same time, CO2 emission from the cultivation was reduced.
