摘要
通过田间试验研究了浆果膨大期至着色期不同钾肥施用量对赤霞株葡萄产量、品质影响。经过2 a试验,结果表明:赤霞珠葡萄浆果膨大期至着色期,施用N∶P2O5∶K2O为1∶1∶1.5的混配肥料最利于可溶性固形物、可溶性总糖和花青苷含量提高;在一定范围内,随钾肥用量的增加,赤霞珠葡萄产量随之提高。
Yield experiments were carried out to determine the effects of different K rates on yield and quality of Cabernet Sauvignon grape during the stage from berry swelling to coloring.The results showed that the optimum ratio of N∶P2O5∶K2O was 1∶1∶1.5 for improving soluble solids,soluble sugar and anthocyanin contents of Cabernet Sauvignon grape;In a certain range,the yield of Cabernet Sauvignon grape increased with increasing of K rate.
