| 摘 要： | 为了进一步制定出新中78大白菜配套的高产、高效、优质、安全的种植技术规程，实现良种良法配套推广，在2012年肥料试验的基础上，又开展了一次肥料试验，同时测定了硝酸盐含量。研究结果表明，以莲座末期追施尿素20 kg/667 m2，结球初期追施尿素20 kg/667 m2较好，硝酸盐含量略高，但与对照习惯施肥(结球初期一次性追施尿素40 kg/667 m2)相比较低，且产量较高。

| Abstract: | To formulate the high-yield, efficient, high-quality and safe planting technical specification for Chinese cabbage cultivar Xinzhong 78, and popularize this set of fine seed and fine method, another fertilizer test of Xinzhong 78 was carried out based on the one conducted in 2012, and the nitrate content was measured at the same time. The results showed that it was better to top dress urea 20 kg/667 m2 at the late rosette stage and 20 kg/667 m2 at the early heading stage, which the nitrate content was a little higher, yet compared with traditional fertilization (top dress urea 40 kg/667 m2 one time at the early heading stage) was relatively lower, and the above fertilizing method tended to promote a higher yield. |
