香菇废料秸秆反应堆在平泉市温室越冬茬黄瓜栽培中的应用

Effect of shiitake waste straw reactor on overwinter cucumber cultivation in greenhouse in Pingquan city

为探索平泉市香菇废料作为秸秆反应堆填充物在温室越冬茬黄瓜栽培上的应用效果,以传统种植方式为对照,研究了以整株玉米秸秆、粉碎玉米秸秆、玉米芯、香菇废料为填充物的秸秆反应堆对黄瓜生长、土壤理化性质和细菌多样性的影响。结果表明,香菇废料秸秆反应堆可以明显增加黄瓜株高、茎粗和总节数,小区产量比对照显著提高12.25%,与生产上常用的整株玉米秸秆反应堆无显著差异;显著提高了土壤pH以及有机质、碱解氮和速效磷含量,降低了EC值,与对照相比有机质含量增加了35.01%,EC值降低了19.76%;显著提高了土壤细菌多样性,改变了细菌的群落结构,增加了有益细菌数量。综合分析认为,香菇废料可以作为温室越冬茬黄瓜秸秆反应堆填充物,在平泉市等香菇废料丰富的地区使用,从而实现农业废弃物循环利用。

To explore the effect of shiitake waste added to the straw reactor for overwinter cucumber production in greenhouse in Pingqun,traditional planting methods were used as control,cucumber growth,soil physical and chemical properties and bacterial diversity were studied with the treatment of straw reactor filled with whole corn stalk,crushed corn stalk,corn cob and shiitake waste were.The results showed that the shiitake waste added straw reactor significantly increased plant height,stem diameter and total node number of cucumber,and the yield was 12.25%higher than that of the control,similar to the commonly used whole corn plant straw reactor.Soil pH,organic matter,alkali-hydrolysable nitrogen and available phosphorus were significantly increased,and EC was decreased.Compared with the control,organic matter was 35.01%higher,EC was 19.76%lower,so soil physical and chemical properties were improved.Shiitake waste significantly increased the diversity of soil bacteria,changed the community structure of bacteria,and increased the number of beneficial bacteria.Comprehensive analysis shows that shiitake waste can be used as straw reactor filling material for overwinter cucumber production in greenhouse in Pingquan city and other areas where shiitake waste is abundant.
