摘要
以4年生"玫瑰香"葡萄为试材,设置改良霍格兰营养液0.5、1.0、1.5倍3个浓度,探讨了不同养分供应量对"玫瑰香"葡萄树体营养生长、光合特性和果实品质的影响。结果表明:不同营养液浓度处理下的新梢长度、粗度和主干基部直径均表现为1.5倍>1.0倍>0.5倍,0.5倍浓度和1.0倍浓度处理下的净光合速率高于1.5倍浓度,果实的可溶性固形物和花色苷含量均表现为1.0倍浓度处理最大,而可滴定酸含量为1.5倍>0.5倍>1.0倍。从整体情况来看,适当提高营养液浓度(1.0倍),有利于增加可溶性固形物、降低可滴定酸含量和果实的提前着色;营养液浓度过高时,可溶性固形物含量反而下降,可滴定酸含量增加,不利于提高果实品质和果实风味物质的形成。
The four-year-old‘Muscat Hamburg＇grape was used as test material.Set 0.5time,1.0time,1.5times as compared concentrations Hoagland nutrient solution,the effects of different nutrient supply on photosynthesis and fruit growth in‘Muscat Hamburg＇grape were studied.The results showed that the higher the concentration,the longer and bigger the shoots,the bigger the stem,the net photosynthetic rates under 0.5time and 1.0time were higher than 1.5times,the contents of soluble solids and anthocyanin were the biggest under1.0time,but the titratable acid content had an opposite trend,1.5times0.5time1.0time.Taken as a whole,proper solution concentration was helpful in improving soluble solids,decreasing titratable acid and coloring fruit in advance;too high nutrient solution concentration was not good for increasing fruit quality and the formation of fruit flavors,while the content of soluble solids reduced,the content of titratable acid increased.
