BR-120是油菜素内酯(简称BR)化合物的一种,它是新型的植物甾体激素。据报道,它在极低浓度下具有刺激食用菌细胞生长,增加蛋白质含量及提高产量的效果。为此,我们以灵芝为试材进行了试验。 一、材料和方法 (一)试验材料 ①菌种为泰山灵芝,引自聊城师范学院生物系。②栽培料配方:棉子壳80％,麸皮10％,玉米面5％,豆面3％,石膏、过磷酸钙各1％,料水比1:1.4,pH值自然。③试剂为叶光牌BR-120,由云南大学研制生产,使用时稀释成5组浓度(ppm):A.10~(-1);B.10~(-2);C.10~(-3);D.10~(-4);E.10~(-5);以清水为对照。
BR-120 is a brassinosteroid (BR) compound, which is a new plant steroid hormone. It has been reported that it has the effect of stimulating the growth of mushroom cells at very low concentrations, increasing the protein content and increasing the yield. To this end, we tested Ganoderma lucidum as a test material. First, the material and methods (a) test materials ① Taishan Ganoderma lucidum bacteria, cited in Liaocheng Teachers College Department of Biology. ② Cultivation recipe: Cotton seed shell 80%, bran 10%, corn flour 5%, 3% soy bean paste, gypsum, superphosphate 1%, feed water ratio 1: 1.4, pH value natural. The reagent is Ye Guang BR-120, developed and produced by Yunnan University. When used, it is diluted into 5 groups of concentration (ppm): A.10 ~ (-1); B.10 ~ (-2); C.10 ~ -3); D.10 ~ (-4); E.10 ~ (-5); with water as control.
