| 摘 要： | 以地方品种金乡白皮蒜为试材,研究不同氮肥处理对大蒜蒜薹和鳞茎产量的影响,以及在适宜施氮量的条件下,大蒜干物质积累及养分吸收的情况。结果表明:每生产1000kg大蒜需从土壤中吸收氮8.5kg、磷1.4kg、钾5.2kg。从播种到鳞芽花芽分化期(180d),大蒜干物质日均积累量相对较低,对氮、磷、钾的吸收量分别占整个生育期的30.7%、36.8%和46.1%;从鳞芽花芽分化期到收获(52d),蒜薹伸长、鳞茎膨大,大蒜干物质日均积累量迅速增加,对氮、磷、钾的吸收分别占整个生育期的69.3%、63.2%和53.9%,到收获前期干物质积累和养分吸收达到高峰。本试验条件下适宜氮素用量为240kg·hm-2,大蒜对氮、磷、钾的吸收分别为0.710、0.114和0.434g·株-1,吸收比例为1∶0.16∶0.61。

| Abstract: | The experiment was conducted with local variety Jinxiangbaipisuan for studying accumulation of dry matter and nutrient uptake of garlic with six treatments of N fertilization.The result showed that garlic uptook N 8.5 kg,P 1.4 kg and K 5.2 kg from soil when the yield was 1 000 kg.It took 180 days from planting to bulbil differentiation,in which stage the accumulation of dry matter and uptake of N,P and K everyday were less.It took 52 days from bulbil differentiation to harvest,in which stage scape growed an... |
