摘要
为探索适合水稻旱直播栽培的施肥方法,开展不同基肥用量的小区试验。试验结果表明:水稻旱直播施用不同数量三元复合肥作基肥,以每667m2施复合肥25kg产量最高;每667m2施复合肥17.5～25kg比不施基肥明显增产。
To explore suitable fertilization method of rice direct seeding on dry land, plot experiment of different base-manure amounts was designed and carried out. The results show that to apply differ- ent amounts of triplet S-NPKI compound fertilizer on dry paddy field by 25kg/667m2 can reach the highest yield. To apply 17.5-25kg/667m2, the rice yields can be increased significantly than none base-manure treatment.
