【摘要】 【目的】探究有机无机复混肥在旱作谷子上的施用效果。【方法】通过大田试验设置不施肥(CK)、有机无机复混肥(YW)、等养分的纯化肥(HF)和等价格的复合肥(DJ)4种施肥处理,对谷子农艺性状、产量、品质和经济效益等相关指标进行测定。【结果】施肥均能促进谷子的生长,其中YW处理的施用效果最为明显;YW处理与HF处理相比,谷子农艺性状差异显著(P<0.05),株高、茎粗、穗长分别提高了4.97%、4.58%、3.91%。YW处理与HF处理、DJ处理相比,产量和经济效益分别提高了202.9、178.5 kg/hm~2和750.9、1 035.3元/hm~2,籽粒中粗蛋白质、粗淀粉和粗脂肪含量分别提高了6.36%、1.50%、6.99%和2.39%、1.04%、3.38%,且产量与品质性状均差异显著(P<0.05)。【结论】施用有机无机复混肥能够有效提高谷子产量、改善谷子品质,增加收入。更多还原

【Abstract】 【Objective】To explore the application effect of organic and inorganic compound fertilizer on dryland millet.【Methods】Millet′s agronomic traits,yield,quality,and economic benefits were assessed using four fertilization treatments:no fertilization(CK),organic and inorganic compound fertilizer(YW),chemical fertilizer with same amount of nutrient(HF),and compound fertilizer with the same price(DJ). 【Results】Fertilization made millet grow faster,and the YW treatment had the best result. The agronomic parameters of millet were significantly different in the YW treatment compared to the HF treatment(P <0.05),with plant height,stem diameter,and panicle length increasing by 4.97%,4.58%,and 3.91%,respectively.Compared with HF treatment and DJ treatment,YW treatment increased yield and economic benefits by 202.9,178.5 kg/hm~2 and 750.9,1 035.3 yuan/hm~2. Crude protein,crude starch,and crude fat in grains increased by 6.36%,1.50%,6.99% and 2.39%,1.04% and 3.38%,respectively(P <0.05). 【Conclusion】The use of organic and inorganic compound fertilizer could improve the millet yield,quality,and increase income.更多还原
