沼渣、食用菌菌渣对香蕉生长和结果的影响

Effect of mushroom substrate and biogas residue on the growth and fruiting of banana

香蕉施用沼渣和食用菌菌渣试验结果表明,菌渣或沼渣对香蕉生长和结果的影响效果显著;二者混合施用比单独施用的效果好,对叶面积、叶片数、果穗重、果指数、头梳果重和果数的影响比较明显,混合施用还显著增加了果实钾的含量,肥料用量与钾含量间的相关性显著。单独施用时,菌渣的效果明显好于沼渣,株施沼渣16 kg或菌渣20 kg比较合适。

The result of the experiment of applying the biogas residue and mushroom substrate to banana plants indicated that the effect of the mushroom substrate or the biogas residue on the growth and the fruiting of bananas is significant;the treatment of the mixed fertilizer of the two performs better than the treatment of either of them separately,especially on the effect of the leaf area,leaf quantity,fruit bunch weight,fruit finger quantity,the first hand numbers and weight.The mixed fertilizer also significantly increased the content of total potassium with the quantity of the fertilizer significantly correlating with the content of total potassium. When being fertilized separately, the mushroom substrate performs better than the biogas residue, but neither of their quantities significantly correlates with the growth or fruiting, which indicates the quantity of application must he controlled; fertilizing each banana plant withl6kg biogas residue or 20kg mushroom substrate one year seems to be a proper treatment.
