Abstract:In order to achieve efficiently utilize water and fertilizer of seed maize in Shiyanghe basin,field experiments were conducted to study the effect of 4 factors, irrigation quota(A); irrigation frequency(B); topdressing frequency(C); topdressing quota(D), with 3 levels respectively on soil moisture and seed maize yields under ridges and furrows irrigation systems with film mulching. Results showed that irrigation quota had significant effect on the soil moisture of 60-100 cm soil profile in jointing when irrigation quota is more than 400 m3/hm2.In addition, it could significantly extend the vegetative growth cycle of seed maize and improve crop plant height; In comparison with other experimental factors, irrigation quota has the maximum effect, followed by irrigation frequency, topdressing frequency and topdressing quota. The water and nutrient schedule with total irrigation quota of 3 000 m3/hm2 with 6 irrigation frequency(seeding, pre-jointing, later jointing, heading, filling, mature, respectively)and topdressing quota of 200 kg/hm2 in jointing, was effective and optimal in Shiyanghe basin.
