灰树花工厂化设施栽培出菇技术优化试验

为了总结优化灰树花出菇和开片的关键技术和时机,对比分析了光诱导催蕾时机、开袋出菇时机和袋口保湿措施3个因素对灰树花工厂化袋栽的单产、朵形和开片率的影响。结果表明:在本试验设计处理中,A2B1C2组合的单产、菇丛体积和开片率均表现最优;因此得出最优的栽培工艺为:双层装袋,走菌满袋后10 d控制光照度在50~100 lx下进行光诱导;袋口菌丝组织化、分泌出细密的小水珠、开始皱缩时,菌包开袋进行出菇管理,控制环境温度在22~25℃,湿度在90%~95%,CO2浓度低于0.1%,光照度为200~500 lx;开袋时切除外袋10 cm以上部分,内外袋间蓄水出菇,开片后期除去外袋直至采收。

Optimization Experiment of Grifola frondosa Fruiting Technology in Factory Cultivation

In order to summarize and optimize the key technologies and timing of influencing the fruiting and slice of Grifola frondosa,the effects of three factors,i.e.the time of light-inducing primordia formation,the moment of opening bag and the measure of moisturizing at the bag mouth,on the unit yield,fruiting body figure and opening rate of industrialized bag planting of Grifola frondosa were compared and analyzed.The results showed that A2B1C2 had the best yield,the volume of mushroom clump and the rate of opening in this experiment.Therefore,the optimal cultivation technology was as follows:loading with two bags,illuminating with 50-100 lx LED light to induce the primordia induction at 10th day after mycelia growing full of bag,moving bags into mushroom house in which environmental temperature controlled at 22-25℃,humidity at 90%-95%,CO2 concentration below 0.1%,and light intensity at 200-500 lx,and opening bags when hyphae became to fine droplets and shrink.When opening the bag,it should cut off the part above 10 cm of the outer bag,store water between the inner and outer bags to produce mushrooms,remove the outer bag at the later stage of opening the bag until harvest.
