| 摘 要： | 研究了不同施氮水平对花椰菜生长和产量的影响,以期为江苏沿江高沙土地区花椰菜高产的适宜施氮量提供依据.结果表明:不同的施氮量处理间花椰菜产量存在显著差异,施氮能显著提高花椰菜产量,但施氮量达到一定值后,继续增施氮肥产量下降,说明花椰菜施氮量存在阈值.在该试验条件下,花椰菜氮肥的施用量应控制在38 kg/667m2,试验推荐施氮量是在江苏省泰州市高港区的土壤及生态条件下的试验结果,对当地及江苏沿江高沙土地区花椰菜氮肥施用具有一定的参考价值. |

| Abstract: | The different nitrogen application amount on influence of growth and yield of cauliflower were studied.The results showed that the nitrogen content of local sandy soil area couldn’t totally meet the needs which the cauliflower growth,the suitable supplement of nitrogen fertilizer had certain production increase effect to the cauliflower yield,but after the amount used surpasses certain value,the cauliflower yield reduces instead.In the local sandy soil area,the suitable nitrogen application amount of cauliflower was about 38 kg/667m2,which could reduce the production cost and raise the cauliflower yield.The results had certain reference value along the river to this locality and the Jiangsu high sandy soil area for cauliflower nitrogenous fertilizer employment. |
