在食用菌生长发育过程中离不开矿物盐磷和钾。常规配方基质中的磷、钾足以供食用菌的利用,然而无粮栽培是在常规配方的基础上以一定数量的尿素取代麸皮,这样的基质磷、钾含量不足。为了探讨磷、钾含量高的矿物盐——磷酸二氢钾对黑木耳无粮栽培的增产效应,做了些研究收到了很好的效果。一、材料与方法(一)材料菌株为Au8402,引自河北省科学院微生物所,是我区无粮栽培的当家种。配方A.蔗渣98.3%,尿素0.5%,碳酸钙1%,磷酸二氢钾0.25;配方B.蔗渣98.5%,尿素0.5%,碳酸钙1%。加水均为干料的2倍。采用17×34×0.05～0.06cm 的聚丙烯塑料袋。
In the process of mushroom growth and development can not be separated from mineral salts of phosphorus and potassium. Phosphorus and potassium in conventional formulation matrices are sufficient for the use of edible fungi. However, non-grain cultivation is based on the conventional formula with a certain amount of urea instead of bran, so that the content of phosphorus and potassium is not enough. In order to explore the high phosphorus and potassium mineral salt - potassium dihydrogen phosphate blackleg yield-increasing cultivation effect, done some research has received very good results. First, the material and methods (A) Material Strain for the Au8402, cited from the Institute of Microbiology, Hebei Academy of Sciences, is a non-food cultivation in our region headed species. Recipe A. Bagasse 98.3%, urea 0.5%, calcium carbonate 1%, potassium dihydrogen phosphate 0.25; formulation B. Bagasse 98.5%, urea 0.5%, calcium carbonate 1%. Add water are 2 times the dry material. Using 17 × 34 × 0.05 ~ 0.06cm polypropylene plastic bags.
