不同包膜控释肥对花生生物性状及养分含量的影响

Effects of Different Coated Controlled-release Fertilizers on Peanut’s Biological Traits and Nutrient Content

不同包膜控释肥对花生生物性状及养分含量的影响试验结果表明,与习惯施肥相比,不同包膜控释肥处理的花生单株果数增加16.67%～50.00%,花生果干重增加1.29%～16.34%,而在花生果鲜重、百粒重、出米率方面控释肥没有表现出明显的优势;包膜控释肥处理的花生秧单株干重增幅为1.13%～6.32%,在花生秧单位面积株数、株高、单株鲜重方面也无显著影响;在花生养分含量方面,施用包膜控释肥后,花生钾含量增加5.88%～14.71%,对花生氮、磷含量的影响不显著。

Effects of different coated controlled-release fertilizers on peanut＇s biological traits and nutrient content were studied by field experiment.The results showed that coated controlled-release fertilizers could increase peanut＇s number per plant by 1＆67%-50.00% compared with conventional fertilizer,peanut＇s fruit dry weight were increased by 1.29%-16.34%, while coated controlled-release fertilizers didn＇t perform clear advantages on fresh weight, 100-grain weight and producing-rice effficiency.The dry weight of peanut straw treated by different coated controlled- release fertilizers were increased by 1.13%-6.32% ,peanut＇s strain number,strain height and strain fresh weight treated by different fertilizers hadn＇t significant difference. After using coated controUed-release fertilizers, the content of peanut＇s potassium increased by 5.88%-14.71%. The content of peanut＇s nitrogen and phosphorus hadn＇t clear advantages compared with conventional fertilizer.
