摘要
研究了不同密度和氮磷钾肥料等因素组合对天隆1号产量和经济性状的影响,结果表明:不同密度与肥料组合的天隆1号产量在143.60~192.49 kg/667m^2,其中处理8(A3B2C1D3)产量最高,达到192.49 kg/667m^2,处理7(A3B1C3D2)、处理9(A3B3C2D1)的产量分别为185.69 kg/667m^2、182.36 kg/667m^2,分列二、三位。密度是影响天隆1号产量和经济性状的主要因素,对产量及部分经济性状的影响达显著水平,而氮磷钾等肥料因素是次要因素。综合方差分析结果和变异系数来看,不同因素对天隆1号的影响效应大小依次为种植密度>氮肥>磷肥>钾肥。
The effects of different planting densities and fertilization rates on yield and economic traits of soybean cultivar Tian-long 1 in the upland of Red soils were investigated. The results showed that the rangeof yields was around 143.60~192.49 kg/667m2 with, the highest yield of 192.49 kg/667m2 from treatment A3B2C 1D3, while yields in treatments A3B 1 C3D2 and A3B3C2D 1 were 185.69 kg/667m2 and 182.36 kg/667m2 respectively. Planting density was the first and main factor influencing yield and economic traits of soybean cultivar Tian- long 1, and the fertilization rates came the second. The order of yield- influencing effect was density〉nitrogenous fertilizer〉phosphate fertilizer〉potassium fertilizer.
