| 摘 要： | 采用水量平衡原理,通过大田小区试验与理论分析,对与10年生核桃间作的滴灌大豆耗水规律进行了研究。结果表明,果农间作的滴灌大豆花夹期、鼓粒期、鼓粒成熟期的平均日耗水强度分别为3.2、3.3、2.3 mm,全生育期累积耗水量为277.2 mm,较非间作滴灌大豆各生育期的日均耗水量显著减小,总耗水量减小26.5%,日均耗水量变化也更为平缓;果农间作的滴灌大豆在观测生育期内的平均叶绿素含量较非间作大豆减少24.6%。

| Abstract: | Rule of soybean water consume that irrigated by drip irrigation method was studied based on water balance principle and field experiment.Result turned that under condition of experiment,daily water consume of soybean in flowering-poding phase,seed-filling phase and maturity phase are 3.2 mm,3.3 mm,2.3 mm.Cumulated water consume of growth phase are 277.2 mm.Obvious decrease of daily water consume can be seen,total water consume reduced by 26.5% and variation of daily water consume is more smooth compare with soybean under drip irrigation method and non-intercropping condition.24.6% decrease of average chlorophyll content of soybean in growth phase can be seen compare to non-intercropping ones. |
