稻菇套种的增产措施及其田间小气候变化的研究

采用室内试验与田间小区试验相结合,田间调查及生态因子测定与室内分析相结合的研究方法,研究了8个品种中熟稻和6类食用菌在水稻试验田的套种情况,分析了田间小气候的变化、光能利用率、节水增肥和生物防治效应,提出了配套措施。研究结果表明,食用菌菌袋采用34.00 cm×17.00 cm×0.04 cm聚乙烯袋,套种量为60 000袋/hm2为宜。按此套种量水稻达到合理密植,中后期合垄遮阴较好,可满足食用菌在下层对光照的需求,食用菌又可充分利用稻行空间,达到二者生态因子互补互利,协同提高经济效益。

Study on Yield Increase Effect of Edible Fungi and Rice Interplant and its Field Microclimate

Combined the lab test and field plot test,field investigation and ecologic factor determination and lab analysis,the interplant effects of 8 middle-late rice varieties and 6 kinds of edible fungi in rice test field were studied.And the change of field microclimate,light energy utilization rate,and effect of saving water and increasing fertilization and biology control were analyzed.Results showed that it was suitable to use the edible fungi polyethylene bag of 34 cm×17 cm×0.04 cm and the interplant amount was at 60 000 bags/hm2,which could had effect of rational close-planting,better shading in linked ridge in middle-late stage and meet the sunlight need in low layer by edible fungi.The edible fungi could fully use the space of rice rows and had effect of complementary of two ecologic factors,which cooperated to increase ecologic benefit.
