Experiment on fruit-crop intercropping soybean water consume rule in drip irrigation

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