从1985年开始,我们在襄樊市保康、南漳、谷城等地,用了六年多的时间,进行了大量的黑木耳施用氮磷钾、微肥和激素的试验示范研究,基本摸清了黑木耳优质高产的矿质营养规律,为发展黑木耳生产提供了科学依扭。一、为什么要给黑木耳补充营养 1.黑木耳正常生长所需的营养与段木内含的养分不一致。黑木耳生长对矿质营养需要量在5％以上,而一般段木含木质素、纤维素60％以上,脂溶物水溶物5％左右,氮0.03～0.1％,磷、钾、铁等灰分元素低于0.5％,无法满足黑木耳正 Starting from 1985, we spent more than six years in Baokang, Nanzhang, Gucheng and other places in Xiangfan City. We conducted a large number of pilot demonstration studies on the application of NPK, trace fertilizers and hormones to black fungus. Clear black fungus quality and high yield of mineral nutrition law, black fur production for the development of scientific basis. First, why do you want to add nutrition to black fungus 1 black fungus nutrition required for the normal growth and section wood contains nutrients are inconsistent. Black fungus growth of mineral nutrition needs more than 5%, while the general wood lignin, cellulose more than 60%, fat soluble matter about 5%, nitrogen 0.03 to 0.1%, phosphorus, potassium, iron and other ash elements Less than 0.5%, can not meet the black fungus positive
