亏缺灌溉对自根与嫁接甜瓜生长发育及产量的影响

以厚皮甜瓜（伊莉莎白）、白籽南瓜砧木（青研一号）为材料,研究亏缺灌溉对自根甜瓜（T）与嫁接甜瓜（J）生长发育以及产量的影响。营养生长期灌水下限统一为田间持水量（field water holding capciaty,FC）的65%,生殖生长期设3个灌水下限,分别为T85（自根甜瓜85%FC）、T65（自根甜瓜65%FC）、T45（自根甜瓜45%FC）、J85（嫁接甜瓜85%FC）、J65（嫁接甜瓜65%FC）、J45（嫁接甜瓜45%FC）。结果表明：1）自根与嫁接甜瓜株高和茎粗在定植后的第9天表现出差异,并随着生长天数增加而增加;果实膨大期叶面积为T85〉J85〉J65〉T65/T45〉J4...

Summary:以厚皮甜瓜（伊莉莎白）、白籽南瓜砧木（青研一号）为材料,研究亏缺灌溉对自根甜瓜（T）与嫁接甜瓜（J）生长发育以及产量的影响。营养生长期灌水下限统一为田间持水量（field water holding capciaty,FC）的65%,生殖生长期设3个灌水下限,分别为T85（自根甜瓜85%FC）、T65（自根甜瓜65%FC）、T45（自根甜瓜45%FC）、J85（嫁接甜瓜85%FC）、J65（嫁接甜瓜65%FC）、J45（嫁接甜瓜45%FC）。结果表明：1）自根与嫁接甜瓜株高和茎粗在定植后的第9天表现出差异,并随着生长天数增加而增加;果实膨大期叶面积为T85〉J85〉J65〉T65/T45〉J45;果实成熟期叶面积为T85/J85〉J65〉T65〉J45〉T45;不同水分处理下甜瓜根与地上部分干质量均随水分下限降低而降低,而根冠比随水分降低而升高;不同灌溉水分下限处理甜瓜产量从高到低的顺序为J85/T85〉J65〉T65〉J45〉T45,在亏缺灌溉中,嫁接甜瓜水分利用效率及产量均高于自根甜瓜,以J65处理最高。相对于充分灌溉处理,J65处理比T85与J85分别降低17.3%、21.6%,但J65的水分利效率比J85与T85分别增加30.5%、37.7%。研究可为深入了解自根与嫁接甜瓜生殖生长阶段水分需求规律、促进设施甜瓜增产提供依据。
Bibliography:Deficit irrigation is an effective method for water resource saving while maintaining crop yield. This study aimed to investigate effects of different irrigation low limits on yield and growth of self-rooted and grafted muskmelon in greenhouse. The experiment was conducted in 2015 in a plastic greenhouse of Huazhong Agricultural University, Wuhan, China（114？22？E, 30？29？N）. The soil was clay-loam with field water holding capacity（FC） of 32.6%. Three different drip irrigation low limits were designed based on FC including 45%FC, 65%FC and 85%FC during the reproductive stage of self-rooted and grafted muskmelon and for all the treatments the irrigation lower limit in the vegetative growth stage was kept as 65%FC. There were a total of 6 treatments, and each replicated 3 times. The muskmelon species was Elizabeth with a growing period of 90 d. The white seed pumpkin was used as the graft stock for the grafted muskmelon treatments. During the experiment, the measurements were leaf SPAD, plant height, stem diameter
