羊肚菌栽培外源营养袋功能解析

羊肚菌栽培正在我国蓬勃展开,然而,羊肚菌栽培中的关键技术环节外源营养袋的功能还不清楚。本文在文献评述的基础上,结合科研生产实践,对外源营养袋的功能进行了解析。用贫营养(土壤)和富营养(营养袋)相结合的方法栽培羊肚菌,可明显地分为四个时期,土壤中菌丝生长、营养袋中菌丝生长、土壤中菌核形成和诱导菌核萌发产生子实体。菌核发育过程中,存在着生长中心菌核(库)和营养袋菌丝(源)之间营养物质的转运。营养袋菌丝中的营养物质转运至土壤菌丝和菌核中,为菌核发育提供营养。

Exogenous Nutrition Bag in Morels Cultivation: Research Progress

Morels (Morchella spp.) cultivation is booming in our country. However, the function of the exogenous nutrient bags, the key technical link in morels cultivation, is still unclear. In this study, the function of exogenous nutrition bags is analyzed based on the literature reviews and scientific research and production practices. The processing of the morels cultivation using the combination of nutrient poor substratum (soil) and nutrient rich substratum (nutrition bags) is clearly divided into four periods: mycelial growth in soil, mycelial growth in nutrition bags, sclerotial formation in soil and sclerotia induced to produce fruiting bodies. During the trigger and development of sclerotia, translocation of nutrients occurs from the mycelia in the bags that serve as a source to the growth center sclerotia that act as a sink. Thus, the mycelia in the bags translocate their nutrients to the mycelium and sclerotia in soil for the sclerotia initial and formation.
