近几年,我市有些菇农因在平菇栽培料中加了一定量的磷酸氢二铵后,菌丝普遍生长缓慢细弱无力,有的后期便死亡,污染率很高,损失惨重。笔者随即就此问题进行试验,找到了危害菌丝生长就是栽培料中加了磷酸氢二铵。下面就谈谈其危害原因及补救措施。 (一)原因分析 平菇栽培料中一般要加入1%～2%的磷肥,这里的磷肥是指过磷酸钙,而有些菇农认为是磷酸氢二铵。为调整栽培料的PH值,平菇栽培料
In recent years, some mushroom growers in our city due to the mushroom material added to a certain amount of diammonium phosphate, mycelium generally slow and weak, some later died, the pollution rate is high, heavy losses. I immediately tested on this issue and found that the growth of mycelium damage is added to the cultivation of the material added diammonium phosphate. Here to talk about its causes and remedies. (A) the reasons for the analysis Pleurotus ostreatus materials generally have to join 1% to 2% of the phosphate fertilizer, where the phosphate refers to superphosphate, and some mushrooms that is diammonium phosphate. To adjust the PH value of planting materials, mushroom cultivation materials
