摘要
在青铜峡市良种繁殖场利用田间小区试验，采用“3414”试验方案，研究了氮磷钾肥施用量及不同比例对水稻产量构成、产量及经济效益的影响。结果表明：合理配施氮磷钾肥能够提高水稻的产量，产量增幅为8．69％-77．41％。其中以处理⑥N2P2K：产量最高为8271．0kg／hm^2，增产率为77．41％。结合当地农业生产实际和施肥经验，该土壤类型种植水稻的推荐施肥量为纯N217．7～242．0kg／hm^2、P20561．5-98．8kg／hm^2、K2052．2～95．7kg／hm^2。
An experiment was conducted at Qingtongxia Municipality Seed Breeding Farm using the field plot experiment and ＂3414＂ test plan to research the effects of different dosages and proportions of nitrogen, phosphorus and potassium fertilizers on the rice yield components, yield and economic benefit. The results showed that the reasonable ratio of N, P and K could increase the yield of rice by 8.69%-77.41%, of which the yield with the treatment of ⑥N2PzK2 was the highest as 8 271 kg/hm^2, an increase by 77.41%. In combination with the local practical experiences in the agricultural production and fertilizer application, the recommended fertilization quantities for the rice growing on the soil type are pure N 217.7 - 242.0 kg/hm^2, P2Os 61.5- 98.8 kg/hm^2 and K2O 52.2 - 95.7 kg/hm^2.
