Analysis of Underground Drainage Pipe Layout Impact on Rice Yield and Nitrogen Loss with DRAINMOD_NII
Rational drainage tube arrangement can effectively increase rice yield and reduce nitrogen loss.The effects of different drainage DRAINMOD_NII model on rice yield and nitrogen loss in Zhuluoba irrigation district were analyzed.The results showed that the rice yield was the highest when the tube spacing was 90m and the buried depth was 90cm.The cumulative nitrogen loss decreased with the increase of drainage tube spacing,and the greater the cumulative nitrogen loss was with the same drainage spacing and the deeper the buried depth.
