我县地处哈尔滨北部,无霜期短,春季风大,空气干燥。春栽平菇,培养料易失水,发菌慢,出菇不整齐,产量低。自1985年以来,我们采用整玉米芯露地栽平菇获得较好效果,比用稻草、麦秸、豆秸、葵花皮栽培生物效率高6～10%。现将具体做法介绍如下:(一)供试菌种:平菇539,引自省微生物所。原种用玉米粒或小麦粒制作,生产种用木屑料制作。(二)基料配制:选新鲜无霉变的整玉米芯,浸入1%石灰,0.1%多菌灵、1%尿素的混合液中12～16小时,捞出后沥水,拌入1%石膏。含水量在65～70%,pH7.2～7.5。(三)露地栽培:选通风、排水好的地块,东西向作床。畦宽1米,长4～6米。4月中旬开始栽培,铺料前畦底要浇透水,撒一层石灰,料厚15～20厘米(每米~2,下料15～20公斤),用铁锹拍平、拍实后,按10厘米行、株距穴播,每米~2用种8～10瓶,料面覆用2%
My county is located in the northern part of Harbin, frost-free period is short, spring monsoon, air-dry. Pleurotus vernalization, culture materials susceptible to water loss, slow bacteria, fruiting irregular, low yield. Since 1985, we use the whole corncob to planted mushrooms to obtain better results than straw, wheat straw, soybean straw, sunflower bark cultivation of biological efficiency of 6 to 10%. The specific practices are introduced as follows: (A) test species: mushroom 539, cited from the provincial microbiological Institute. The original species of corn or wheat grain production, the production of species made of wood chips. (B) the preparation of the base material: fresh mildew-free selection of whole corn cob, immersed in 1% lime, 0.1% carbendazim, 1% urea mixture of 12 to 16 hours, remove and drain, stir in 1% gypsum . Water content in 65 ~ 70%, pH 7.2 ~ 7.5. (C) open field cultivation: election ventilation, drainage of good land, east-west for the bed.畦 wide 1 meter long 4 to 6 meters. Cultivation begins in mid-April, before pouring material to the bottom to pour water, sprinkle a layer of lime, material thickness 15 ~ 20 cm (per meter ~ 2, 15 ~ 20 kg of material), with a shovel pat, 10 cm lines, plant spacing sowing, per meter ~ 2 with species 8 to 10 bottles, material surface coating with 2%
