Mushroom Dregs for Chinese Cabbage Cultivation

In a greenhouse,utilization of mushroom dregs for fertilizing Chinese cabbages was investigated.When the dregs were applied up to 30t/hm2,the yield,plant height and contents of chlorophyll,vitamin C and soluble sugar of the cabbages increased 43.5%,9.7%,26.7%,15.5% and 21%,respectively,as compared with control.The highest nitrate content in the cabbages was 1,120mg/kg found in control.That was reduced by 3.4-24.2%with the dregs application.Consequently,besides improvements on quality,combining the mushroom dregs with regular inorganic fertilizers in the vegetable cultivation could significantly reduce the nitrate accumulated in the cabbages as well.
