毛竹林下竹荪仿野生栽培关键因素对其出菇影响研究

摘要：

为探明毛竹林下竹荪仿野生栽培的关键因素,为竹林下套种竹荪提供理论基础,该研究采用L9(34)正交试验设计研究影响竹荪产量的关键因素,试验设置4个因素:种植时间、菌株、种植方式、基质厚度,每个因素设置3个水平。试验结果表明:4个因素对竹荪的产量和生物学效率均有显著(P<0.05)影响,对菇期均无显著(P>0.05)影响;种植时间显著(P<0.05)影响了发菇用时。浙江地区毛竹林下种植竹荪的最佳栽培模式为3月底在竹蔸周围挖环形种植沟或沿等高线水平状开沟,沟宽30 cm、深10 cm,放置20 cm厚的竹屑基质,使用研究组选育出来的D89菌株进行栽培。

Abstract:

In order to find out the key factors of imitative wild cultivation of Dictyophora indusiata under moso bamboo stands, and to provide theoretical basis for interplanting Dictyophora indusiata in bamboo stands. L9(34) orthogonal test were adopted to study the factors affecting the yield of Dictyophora indusiata. The four factors:planting time, strain, planting mode, cultivation matrix thickness, and each factor was set at three levels. The results showed that the four factors had significant effects on the yield and biological efficiency of Dictyophora indusiata, but had no significant effect on the mushroom growth period (P>0.05). The planting time had significant effects on the mushroom growth period (P<0.05). The best cultivation mode for planting Dictyophora indusiata in the moso bamboo stands in Zhejiang Province is to dig a circular planting ditch around the bamboo stump or open a horizontal ditch along the contour line at the end of March, with a width of 30 cm and a depth of 10 cm, lay substrate of bamboo sawdust with a thickness of 20 cm and use the selected strain D89 by research group for cultivation.

Key words: moso bamboo stands, Dictyophora indusiata, wild cultivation, biological efficiency
