Abstract

Abstract:

In view of the new situation of reducing the fertilizer application and increasing the efficiency in rice production in Northern Huaihe River Valley, the effects of new fertilizers such as Fenghui urea, Jiduosu and loss-control fertilizer on yield and its components, quality traits, and economic benefits of Lianjing 15 and Nanjing 5718 were studied, to explore the effective fertilization methods for increasing yield and improving quality of rice at reduced chemical fertilizer level. The results showed that two combinations of “loss-control fertilizer + Jiduosu + Fenghui urea” and “loss-control fertilizer + Jiduosu + conventional urea” could reasonably combine increased economic benefits based on chemical fertilizer cut with the increase in rice yield and quality, and enjoy a good prospect for demonstration and promotion.

Key words: rice, fertilizer reduction, fertilization technology, Huaibei area

摘要：

针对淮北地区水稻化肥减量增效的新形势,通过丰卉尿素、吉多素、增效控失肥等新型肥料的组配,研究了其对连粳15号直播、南粳5718毯苗机插的产量构成、品质性状、经济效益等的影响,探索化肥减量条件下水稻产量提高和稻米品质提升的有效施肥途径。结果表明,“控失肥+吉多素+丰卉尿素”“控失肥+吉多素+常规尿素”两种组配方式能够将化肥减量增效和水稻产量提高、稻米品质提升有机结合,具有较好的示范推广前景。
