- Abstract:

The experiment of corn irrigation is designed for investigating on the impact of diverse irrigation quotas and pipe laying on corn farmland productivity. Two laying ways of drip irrigation pipes with three different irrigation quotas were used. The results show that during the whole growth season, irrigation volume has significant effects on leaf area as well as photosynthetic potential; it also proves that during jointing and tasseling stages, when irrigation quota is 375 m3/hm2, T2 treatment of laying two drip irrigate pipes in three corn lines has significant difference from CK treatment; when the irrigation quota is 450 m3/hm2, the production with T4 treatment peaked at 17 035.855 kg/hm2 and the water use efficiency is the highest, which is 46.24%,42.50%,26.20%,26.15%,48.23% and 26.15% higher than those with T1, T2, T3, T5, T6 and CK treatements. Therefore, laying two irrigation pipes in three corn lines has greater advantage for corn growth and yield increase than laying three irrigation pipes. That is to say when irrigation quota is 450 m3/hm2, laying two pipes in three lines is the optimal model.
