摘要
在贵州3个主要水稻高产稻田区进行水稻超高产条件下施肥效应研究。结果表明,在3个水稻超高产稻田区,处理3效果最好,即施用氮(纯氮)量为255 kg/hm2、钾量300 kg/hm2、锌量21 kg/hm2条件下水稻经济性状良好,产量最高。在一定范围内,随着施氮量的增加,产量不增加或有减少。施钾量和施锌量在合理施氮条件下呈正相关。
In Guizhou province, effects of fertilization under high yielding condition in 3 major rice paddy field areas were studied, and the results showed that, in the 3 super high yielding rice paddy field areas, the No. 3 treatment showed the best effect, namely under the applications of fertilizer： N 255 kg/hm2, K 300 kg/hm2, Zn 21 kg/hm2 to get good economic performance and the highest yield. In a certain range, with the increase of nitrogen application, yield did not increase but some decreased. K application was positively associated with Zn application in reasonable condition of N fertilizer.
