金针菇地沟栽培两头出菇技术,近年来已在河北省各地推广。利用地沟作为栽培设施,造价低廉,管理方便,适于农家使用,采取袋式堆积排放两头出菇,空间利用率高,山菇面大,产量高,生物学效率在100％以上,且头潮优质菇多,商品率高,比一般栽培方法,提高了经济效益。现总结介绍如下: 一、地沟建造:选择地势高燥、开旷、地下水位较低,有水源,土质以壤土或粘土的庭院或村旁的空间地。挖沟长15米,宽3.8米、高2米,沟内设置3排床架,中间1排床架比两边的高10厘米左右,用数根粗竹竿连接3排床架,搭成弓形棚,棚顶盖上塑料薄膜和麦秸、玉米秸,以保温、保湿 Flammulina cultivation of two mushrooms trench technology, in recent years has been around the promotion of Hebei Province. The use of trench as a cultivation facility, low cost, easy management, suitable for farm use, to take two bags of piled-type deposition of fruiting, space utilization, large mushrooms, high yield, biological efficiency of 100% or more, and the tide Mushrooms and more high-quality, higher than the average cultivation methods, improve economic efficiency. Now summarized as follows: First, the construction of the ditch: Select the high terrain, open, lower groundwater level, water, soil or clay loam soil or space next to the village. Trenching 15 meters long, 3.8 meters wide, 2 meters high, set up 3 rows of bed bed bed, the middle of a row of bedstead about 10 centimeters higher than both sides, with a few thick bamboo poles connected to the 3 bed frame, , Covered with plastic film and wheat straw roof, corn stalks to heat, moisturizing
