| 摘 要： | 在甘薯栽秧之前,基施新型有机-无机缓释肥料.一方面,有利于甘薯早分枝、早结薯,增加结薯数和薯块重量,显著地提高了块根产量.另一方面,可提高块根干物质率以及淀粉和可溶性糖含量,降低块根硝酸盐含量,有效地改善了块根品质.

| Abstract: | The organic-inorganic slow release fertilizer was applied before sweetpotato was planting. On the one hand, applying the slow release fertilizer was favorable to increase divarications, storage roots and storage root weight;The yield of sweetpotato was increased markedly. On the other hand,applying the slow release fertilizer could increase the dry matter percentage, starch content and soluble sugar content in storage root,reduce the nitrate content of storage root. The quality of storage root was improved effectively. |
