不同包膜控释肥对花生生物性状及养分含量的影响

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

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 16.67%～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 efficiency.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 controlled-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.
