| 摘 要： | 为探讨腐植酸对甘薯吸收利用矿质元素的影响，并为研究甘薯植株及土壤中矿质元素含量的变化情况，在大田生产条件下施用腐植酸。结果表明：施用腐植酸以后，甘薯对各矿质营养元素的吸收积累量均显著增加，增幅为12.87%~29.84%；矿质元素吸收积累量增加与腐植酸提高了不同生长时期甘薯对矿质元素的吸收速率有关，生长后期的吸收速率增幅最大。同时，施用腐植酸提高了收获期土壤中有效P、Ca、Mg和K元素的含量；使N、K、Ca、S、B和Cu的块根生产效率显著提高。施用腐植酸可以改善甘薯的矿质营养条件、提高部分矿质元素的块根生产效率。

| Abstract: | The effects of humic acid on nutrient absorption and utilization of sweet potato(Ipomaea batatas LAM.) was investigated by growing sweet potato in field culture in which HA(humic acid) was used.The changes of mineral elements content in sweet potato plant and soil was studied.The test results indicated that the mineral elements absorption and accumulation of sweet potato was increased significantly with amplitude from 12.87% to 29.84% after application of HA.This was related to the mineral elements rate of ... |
