Abstract: Growth status and physiological changes of corn were studied with different irrigation quantity in order to research suitable irrigation amount of seed corn. The results showed that: different irrigation quantity had obvious effect to net assimilation rate and dry treatment seed material of corn, net assimilation rate was big and dry matter accumulation was much because irrigation quantity is much. Leaf area was big, plant growth was fast, height was the highest and contribution rate of water on yield was big, higher yield could be obtained in the irrigation times 5250 m3/hm2 conditions. Irrigation water 5250 m3/hm2 of corn whole growth period can be used as appropriate amount of water saving irrigation quantity in water shortage.
