摘要
为了充分发挥商豆1310的高产潜力,本试验采取五因素二次回归正交旋转组合设计的方法,研究了影响商豆1310产量的种肥、种植密度、追施尿素、多效唑和硼砂5项栽培技术之间的关系,建立了中等以上肥力产量形成的数学模型。经模拟寻优,筛选出了3 750 kg·hm^-2以上产量的最佳栽培量化组合方案,即施用种肥135.8~165.0 kg·hm^-2,种植密度24.4~25.2万株·hm^-2,追施尿素208.5~232.5 kg·hm^-2,喷施多效唑1 932.0~2 140.0 g·hm^-2、叶喷硼砂1 147.8~1 432.2 g·hm^-2。本方案稍作修正后,经2点4.2 hm^2生产示范验证,平均单产3 799.05 kg·hm^-2,较对照增产15.35%,证明方案可行。
In order to give full play of the high yield potention in Shangdou 1310, the quadratic orthogonal regressive rotation design of five factors was applied to study the relationship among five cultivation techniques of seed fertilizer, planting density, topdressing urea, paclobutrazol and borax, which affect the yield of Shangdou 1310, and to establish a mathematical model for yield formation above the middle level soil fertility. Through simulation and selection, the optimum cultivation quantification combination scheme for yield over 3 750 kg·ha^-1 was obtained as following: The amount of applying seed fertilizer was 135.8^-165.0 kg·ha^-1, planting density was 244 000-252 000 plants·ha^-1, the amount of topdressing urea, spraying paclobtrazol and foliar spray borax was 208.5-232.5, 1 932.0-2 140.0 and 1 147.8^-1 432.2 g·ha^-1, respectively. The average yield was 3 799.05 kg·ha^-1 in 2 trial sites of 4.2 ha area, which was 15.35% higher than that of control group, proving that the scheme was feasible.
