摘要
为探究大豆品种商豆151在豫东地区的高效栽培技术,开展田间试验,设置3个种植密度(E1处理为18.0万株/hm2、E2处理为22.5万株/hm2、E3处理为27.0万株/hm2)和3个灌溉定额(W1处理为70 mm、W2处理为100 mm、W3处理为130 mm),研究其对商豆151的水分利用效率和产量及构成因素的影响.结果表明,种植密度与灌水量均显著影响商豆151产量,当种植密度为E3处理且灌溉定额为W1处理时,产量与水分利用效率均达最大值2491.77 kg/hm2、8.27 kg/(hm2·mm).方差分析结果表明,种植密度与灌水量及二者互作对单株荚数、单株粒数、单株粒重等产量性状的影响均达到显著水平.
Abstract
In order to explore the efficient cultivation techniques of soybean variety Shangdou 151 in the eastern region of Henan, field experi-ments were conducted.Three planting densities (180000, 225000, 270000 plants/hm2) and three irrigation quotas (70, 100, 130 mm) were set up to investigate their effects on the water use efficiency, yield and composition factors of Shangdou 151.The results showed that both planting density and irrigation amount significantly affected the yield.When the planting density was E3 and the irrigation quota was W1, the yield and water use efficiency both reached the maximum values of 2491.77 kg/hm2 and 8.27 kg/(hm2·mm).The analysis of variance re-sults showed that the effects of planting density, irrigation amount and their interaction on yield traits reached a significant level, such as pod number per plant, grain number per plant and grain weight per plant.
