我们从1987～1989年连续3年以平菇(pleurotus ostreatus)农大11(编号p64)为材料,采用塑料袋栽培方法。培养料为纯棉籽壳,每个处理8袋,每袋1.25kg,共10kg。播种量按15％,分3层播种(两头和中间各占1/3菌种量)。用药液拌料,0.005,0.05,0.1,0.5 ppm表油菜素内酯(BR)和对照5个处理。观察BR对平菇菌丝体和子实体生长及产量的影响,得到结果如下: 1.促进平菇的生长发育,收菇时间提前,其中以0.1ppmBR处理效果最好;2.增加平菇产量,提高生物学转化率[(每袋平菇子实体鲜重g/每袋棉子壳重量g)×100％](见附表)。
We used the plastic bag cultivation method from the Pleurotus ostreatus Nongda 11 (No. p64) for three years in a row from 1987 to 1989. Culture material for the pure cotton seed hull, each processing 8 bags, each bag 1.25kg, a total of 10kg. Sowing by 15%, divided into three layers of sowing (two in the middle and each of 1/3 bacteria species). With drug solution spice, 0.005,0.05,0.1,0.5 ppm epibrassinolide (BR) and control 5 treatment. The effects of BR on the growth and yield of Pleurotus ostreatus mycelium and fruiting bodies were studied. The results were as follows: 1. To promote the growth and development of Pleurotus ostreatus and advance the harvest time of mushrooms, of which 0.1 ppmBR was the best; 2. Improve the biological conversion rate [(fresh weight per bag Pleurotus fruiting body g / weight per bag of cotton g) × 100%] (see table).
