近几年,菇农采用减少畜粪和增加稻草用量的办法来解决畜粪不足的问题。畜粪与稻草的比例从原来的7:3降为5:5,又降为3:7以至全用稻草。畜粪减少了,不加化肥蘑菇单产难以上去,多加化肥不仅浪费肥料,还会抬致减产,重至造成绝收。因此,研究氮磷钾化肥用量,发展无粪栽培蘑菇是当前发展蘑菇生产急需解决的问题。为此,把四年来无粪栽培磨菇的氮磷钾用量试验总结如下。
In recent years, mushroom farmers to reduce manure and increase the amount of straw used to solve the problem of inadequate manure. The ratio of manure to straw dropped from 7: 3 to 5: 5, to 3: 7 and even to straw. Decreased manure, without fertilizer, mushroom yield is difficult to go up, more fertilizer is not only a waste of fertilizer, but also led to reduce production, resulting in absolute yield. Therefore, to study the dosage of nitrogen, phosphorus and potassium fertilizers and to develop aseptic mushrooms are the urgent problems to be solved in the current development of mushroom production. To this end, the four-year no manure culture mushroom nitrogen, phosphorus and potassium dosage test is summarized as follows.
