为了形成谷子高产栽培技术体系，提升辽西地区谷子生产水平，提高单位面积产量和效益，以燕谷16号为试验材料，采用正交试验设计方法，对制约谷子生产的氮肥施用量（因素 A）、磷肥施用量（因素B）和种植密度（因素 C）3个关键技术进行了不同水平组合的籽粒产量及其经济效益研究，以明确谷子生产上的最佳施肥方案与合理的种植密度。结果表明：3个因素对燕谷16号产量和经济效益的影响顺序均为氮肥施用量＞磷肥施用量＞种植密度，其中，氮肥是影响产量和经济效益的最重要因素，种植密度是影响谷子叶面积指数和穗粒重的最重要因素。本研究条件下，最高产量和最大经济效益的因素组合均为A2 B3 C1，即氮肥施用量187.50 kg /hm2、磷肥施用量131.25 kg /hm2、种植密度30.0万株/hm2时谷子产量和经济效益最高，分别达到了5363.79 kg /hm2和14514.9元/hm2。
為瞭形成穀子高產栽培技術體繫，提升遼西地區穀子生產水平，提高單位麵積產量和效益，以燕穀16號為試驗材料，採用正交試驗設計方法，對製約穀子生產的氮肥施用量（因素 A）、燐肥施用量（因素B）和種植密度（因素 C）3箇關鍵技術進行瞭不同水平組閤的籽粒產量及其經濟效益研究，以明確穀子生產上的最佳施肥方案與閤理的種植密度。結果錶明：3箇因素對燕穀16號產量和經濟效益的影響順序均為氮肥施用量＞燐肥施用量＞種植密度，其中，氮肥是影響產量和經濟效益的最重要因素，種植密度是影響穀子葉麵積指數和穗粒重的最重要因素。本研究條件下，最高產量和最大經濟效益的因素組閤均為A2 B3 C1，即氮肥施用量187.50 kg /hm2、燐肥施用量131.25 kg /hm2、種植密度30.0萬株/hm2時穀子產量和經濟效益最高，分彆達到瞭5363.79 kg /hm2和14514.9元/hm2。

In order to form a system of high yield cultivation technology of millet and promote the millet production level in western Liaoning, increase the yield and benefit of unit area, Yangu No.16 was taking as test material, the effects of different level combinations of 3 key technologies including nitrogen fertilizer (factor A), phosphate fertilizer (factor B) and planting density ( factor C) which restrict the millet production on grain yield and economic effect were studied using orthogonal design method, in order to make clear the optimum fertilization scheme and reasonable planting density.The results showed that the sequence of the 3 factors influence on yield and economic benefit of Yangu No.16 were nitrogen fertilizer >phosphate fertilizer >planting density, wherein, nitrogen was the most important factor to influence the yield and economic benefits, and planting density was the most important factor which largly effected the leaf area index and grain weight per spike of millet.In the test condition,combination of the factors of the highest yield and best economic benefit were A2B3C1 , namely, nitrogen fertilizer, phosphate fertilizer and planting density were 187.50 kg /hm2 , 131.25 kg /hm2 and 300 000 plants /hm2 , respectivly, in which the yield and economic benefit of millet could reach the highest levels , they were 5 363.79 kg /hm2 and 14 514.9 yuan /hm2 , respectively.
