磷钾肥对公酿一号葡萄品种影响的效应分析

摘要

Diammonium phosphate and potassium sulfate in vary proportions were used to fertilize grape Gong-niang No.1 during different periods.The acids in grape were determined by titration.The result showed that sol-id content was increased with adding phosphorus and potassium fertilizer during growing periods and the con -tents of titratable acids were decreased .So,the ration of solids to acidity and output were raised .%　　用磷酸二铵和硫酸钾对公酿一号葡萄品种进行不同时期、不同比例施肥，然后采用滴定等方法对其进行分析测定，结果发现，生长期施磷钾肥能明显提高果实可溶性固形物含量，降低可滴定酸含量，从而提高固酸比，同时作物产量有所提高。
