为探讨黑土水分湿润特征及滴灌对大豆产量的影响,试验采用静脉输液管为工具模拟水分滴灌,以明确点源供水条件下黑土水分湿润特征,并以此为依据确定合理的滴灌模式.研究结果表明:点源供水条件下黑土水分扩散半径约为20 cm.以此为依据,建立了大豆大垄双行滴灌模式,其垄底宽为110 cm,垄顶宽70 cm,大豆双行间距为40 cm;该模式下大豆产量为261.3 kg/667m2,与不灌溉相比大豆产量增加73.0 kg/667m2,增幅为38.8%,增产效果显著,效益明显大于65 cm传统垄作.

To examine the influence of Black soil moisture wetting characteristics and drip irrigation on soybean yield, intravenous tubing was used to simulate water drip irrigation, in understanding the water wetting characteristics of Black soil under the condition of point source water supplying and thus determining the reasonable drip irrigation mode. The results showed that the diffusion radius of Black soil moisture was around 20 cm under the condition of point source water supplying. Based on the result, we
