【摘要】 研究了土壤施入矿质钾镁肥、稻醋液并配合叶面喷施草木灰浸出液、氯化钙溶液等处理对有机桃树体营养及果实品质和抗病性的影响。结果表明:每株桃树土壤施入5kg矿质钾镁肥加150g稻醋液并叶面喷施10%草木灰浸出液,显著增加叶片钾含量,显著增加了单果重、可溶性固形物和总糖含量。每株桃树土壤施入5kg矿质钾镁肥加150g稻醋液并叶面喷施500倍氯化钙溶液,显著增强了叶片和果实钙含量,显著降低了果实桃褐腐病的病情指数。更多还原

【Abstract】 The effect of soil replication of potassium,calcium nutrition and rice vinegar and foliar application of plant ash lixivium and calcium chloride solution on the tree nutrition,fruit quality and fruit resistance based on soil replication of potassium,calcium nutrition and rice vinegar were studied.The results showed that leaf potassium content,fruit weight,soluble solids and total sugar content increased significantly in the treatment of soil application of potassium and magnesium fertilizer 5 kg+rice vinegar 150 g and foliar application of 10% plant ash lixivium.The leaf calcium content increased significantly and the disease index of peach brown rot decreased significantly in the treatment of 0.2% calcium chloride solution.更多还原
