中微量元素对大兴区西瓜产量和品质的影响

中微量元素对西瓜产量和品质的影响试验结果表明,施用中微量元素西瓜产量明显增加7.5%～24.1%,西瓜中心可溶性固形物含量提高0.3～2.0个百分点。综合西瓜产量、瓜瓤中心可溶性固形物含量及中微量元素的含量可知,1.0%硫酸亚铁溶液于伸蔓期、坐果期、果实生长盛期分3次喷施,可获产量62.69t/hm2,同时瓜瓤中心可溶性固形物含量为10.8%,铁、锌、硼和钙的含量较高,依次为6.02、0.59、0.70、10.0mg/kg,适宜在生产中推广应用。

Effects of Secondary and Trace Elements on Yield and Quality of Watermelon in Daxing District

Effects of secondary and trace elements on yield and quality of watermelon were studied.The results showed that the production of microelement was increased by 7.5%～24.1% and watermelon center soluble solids content was improved by percentage of 0.3 to 2.0.Synthesizing with watermelon yield,center soluble solids content and microelements content,1.0%ferrous sulfate solution that was sprayed three times in vine-extending stage,fruit setting stage and fruit expanding stage of watermelon growing period could receive yield of 62.69t/hm2,center soluble solids content was 10.8%,the content of iron,zinc,boron and calcium were high content by 6.02、0.59、0.70 and 10.0mg/kg.The fertilize is suitable for popularization and application in production.
