畸形灵芝是影响商品价值的一个重要因素。造成这种现象,一般只认为是环境条件控制不当所致,所以就加强通风,增加光照,但收效并不是很大。笔者通过实践,采用新的割口方式,不仅克服了这种不足之处,而且还提高了产量,取得了较满意的效果。(一)供试材料灵芝菌株为自繁G_3,于3月29日制备母种。母种培养基配方为:马铃薯200g,葡萄糖20g,琼脂20g,硫酸镁1.5g,磷酸二氢钾3g,味精1.5g,VB_14片,水1000ml。于4月8日制作原种,采用麦粒培养基,其配制方法是:将饱满的小麦粒先在1～2%的石灰水中浸一夜,再换成清水浸泡36小时,泡至麦粒内部无白心时,捞出摊晾,拌入2%石膏粉,表皮晾干后装罐头瓶,置1.5kg/cm~2的压力下保持3小时,冷却后按常规法接入母种、培养。4月26日用原种接入栽培袋,栽培袋配方为:棉子壳100kg,麸皮
Malformation Ganoderma lucidum is an important factor affecting the value of goods. This phenomenon is generally regarded as caused by improper control of environmental conditions. Ventilation and lighting are therefore strengthened. However, the effect is not great. Through practice, the author adopted a new cut method, not only to overcome this shortcomings, but also increased production and achieved more satisfactory results. (A) The test materials Ganoderma strains since the free G_3, on March 29 to prepare the mother species. The formula of the mother culture medium is 200 g of potato, 20 g of glucose, 20 g of agar, 1.5 g of magnesium sulfate, 3 g of potassium dihydrogen phosphate, 1.5 g of monosodium glutamate, VB-14 slices and 1000 ml of water. Produced on April 8, the original species, the use of wheat grain medium, the preparation method is: the first full of wheat grains immersed in 1 to 2% lime water overnight, then replaced with water soaked 36 hours, soaked inside the grain No white heart, remove the stall air, mix 2% gypsum powder, dried epidermis canned bottles, set 1.5kg / cm ~ 2 pressure for 3 hours, after cooling access to the mother by conventional methods, culture . April 26 access to planting bags with the original species, cultivation bag formula: cotton seed shell 100kg, bran
