【摘要】 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。更多还原

【Abstract】 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.更多还原
