在成都金堂县，采用“3414”肥效试验方案探讨了不同氮、磷、钾肥施用量对苦荞麦产量、经济效益及肥效的影响。结果表明，施肥处理苦荞麦产量显著高于不施肥处理，苦荞麦产量分别随着氮、磷、钾肥施用量的增加先增加后降低。纯收入分别随氮、磷、钾肥施用量的增加先增加后降低；产投比随磷肥施肥量的增加而降低，随着氮、钾肥施肥量的增加先增加后降低，即适量减少磷肥的施用量，增加氮肥和钾肥的施用量，可获得较好的经济效益。在低氮、低磷、低钾水平下，两两组合有利于另一肥料肥效的发挥。氮、磷、钾三元二次肥效函数为非典型式，应用产量频率分析法得出每公顷施 N 39.8~86.0 kg、P2O574.6~161.2 kg、K2O 29.8~64.4 kg 时，产量达2000~3500 kg/ hm2的概率为95%，值得推广应用。
在成都金堂縣，採用“3414”肥效試驗方案探討瞭不同氮、燐、鉀肥施用量對苦蕎麥產量、經濟效益及肥效的影響。結果錶明，施肥處理苦蕎麥產量顯著高于不施肥處理，苦蕎麥產量分彆隨著氮、燐、鉀肥施用量的增加先增加後降低。純收入分彆隨氮、燐、鉀肥施用量的增加先增加後降低；產投比隨燐肥施肥量的增加而降低，隨著氮、鉀肥施肥量的增加先增加後降低，即適量減少燐肥的施用量，增加氮肥和鉀肥的施用量，可穫得較好的經濟效益。在低氮、低燐、低鉀水平下，兩兩組閤有利于另一肥料肥效的髮揮。氮、燐、鉀三元二次肥效函數為非典型式，應用產量頻率分析法得齣每公頃施 N 39.8~86.0 kg、P2O574.6~161.2 kg、K2O 29.8~64.4 kg 時，產量達2000~3500 kg/ hm2的概率為95%，值得推廣應用。

A “3414” design experiment was carried out to investigate the effect of nitrogen(N),phos-phorus(P) and potassium(K) application amount on the yield,economic benefit and fertilizer efficiency of tartary buckwheat in Jintang county of Chengdu. The results indicated that the yield of tartary buck-wheat of the treatment with fertilizer was significantly higher than that of the treatment without fertilizer, the yield of tartary buckwheat and the net income increased first and then decreased with the increase of N,P and K application amount. The input and output ratio decreased with the increase of P application amount,and increased first and then decreased with the increase of N and K application amount,indicating that appropriate reduction of the P application amount and increase of N and K fertilizer application amount could attain higher economy benefit. The combination of any two of N,P and K was beneficial to improve the fertilizer efficiency for another fertilizer at a low level. Above all,the application of 39. 8—86. 0 kg / ha N,74. 6—161. 2 kg / ha P2 O5 and 29. 8—64. 4 kg / ha K could obtain 2 000—3 500 kg / ha tartary buckwheat at 95 percent probability,and which was worth generalizing and applying.
