摘要
研究了起垄覆膜沟灌、树盘埋罐渗灌和树盘漫灌对苹果生长发育、产量和品质的影响。结果表明:与树盘漫灌相比,起垄覆膜沟灌和树盘埋罐渗灌能显著增加新梢和春梢的长度,极显著增加叶面积、比叶重和叶绿素含量,但3个处理的新梢粗度、单株新梢数、秋梢长度、秋梢占新梢数的比例以及产量均无显著差异;树盘埋罐渗灌明显增加了根系的数量,且以直径<2mm根增加最多;起垄覆膜沟灌和树盘埋罐渗灌处理的果实品质总体上优于树盘漫灌。
The effects of three different irrigation ways(furrow irrigation with the ridge covered by plastic film,seeping irrigation with buried jar around the tree base,flood irrigation around the tree base) on the growth and development,yield and quality of apple were studied.In comparison with flood irrigation around the tree base,furrow irrigation with the ridge covered by plastic film,seeping irrigation with buried jar around the tree base could significantly increase the length of new tip and spring tip(P < 0.05),and enhance the leaf area,ratio of leaf weight to leaf area,and chlorophyll content(P <0.01).There were no significant differences in the width of new tip,number of new tips per plant,length of autumn tip,proportion of autumn tips to new tips,and yield among 3 kinds of irrigation ways.Seeping irrigation could obviously increase the number of root system,especially the number of the roots less than 2 mm in diameter.The fruit quality of apple in the treatments of furrow irrigation and seeping irrigation was generally better than that in flood irrigation treatment.
