为了探讨金针菇优质高产配方,降低生产成本,从1989～1992年,我们分别以有机氮、无机氮、糖及微量元素做基质辅料,采用不同混合比例进行袋栽试验,探索出了较高产廉价的配方,现将有关结果报告如下。 一、材料与方法 (一)试验配方(％) 试验共设24个配方,现选择其中14个配方组合进行比较。配方1(CK),棉子壳82,麸皮15,糖1。配方2:棉子壳82.5,麸皮15,糖 In order to explore the high quality and high yielding formula of Flammulina velutipes and reduce the production cost, from 1989 to 1992, we used the organic nitrogen, inorganic nitrogen, sugar and trace elements as matrix excipients to carry out the bagging experiment with different mixing ratios to explore the higher yield and lower cost Formula, the results are reported below. First, materials and methods (A) test formula (%) test a total of 24 formulations, 14 of which are now selected combinations for comparison. Formula 1 (CK), Cotton Seed Shell 82, Bran 15, Sugar 1. Formula 2: Cotton Seed Shell 82.5, bran 15, sugar
