| 摘 要： | 在冀西北冷凉气候条件下,采用田间小区试验方法,研究了不同施肥措施对当地主栽萝卜品种生长发育的影响.结果表明:氮磷钾(NPK)配施的萝卜生物量最大.缺少氮、磷或钾任一元素或萝卜生育前期钾素供应不足,均会影响肉质根膨大期以后叶片的生长,甚至导致早衰;同时降低萝卜产量,减产幅度达18.74%～70.38%.萝卜叶片的干物质累... |

| Abstract: | A field experiment was conducted to investigate the effect of different fertilization on growth characteristics of radish under the cold weather condition in the northwest area of Hebei province.The results indicated that the highest yield was obtained by NPK treatment.When nitrogen,phosphorus or potassium was not supplied,or potassium was insufficiently applied during the former growth stage,the leaf growth of radish was significantly affected,and radish yield was reduced by 18.74%-70.38%.The peak of dry m... |
