Abstract
Field experiment was conducted during 2012.03-2012.10at experimental station of Shihezi University(45°19′N,86°03′ E)to study the effect of different levels of drip irrigation and nitrogen fertilizers on sugar beet yield,sugar content,sugar yield and net output value.Based on the field test of quadratic saturation D-optimal design,four irrigation(W1,W2,W3 and W4 with 3000,5610,7200 and 9000m3/hm2)and four N fertilizer(N1,N2,N3and N4with 0,130,210and 300kg/hm2)were arranged in six split plots with 3 replicates.The treatment W4 achieved the highest root yield,sugar yield and net income,followed by W3,W2 and W1.On the contrary,sugar content significantly decreased with the increase of irrigation levels.Increasing N fertilizer use increased root yield,sugar yield and net income,but not significantly.On the other hand,N fertilizer eased the side effect of increasing irrigation on sugar content.W4N3 recorded the highest values while significantly(0.01)decreased the water use efficiency.Compared with CK,mulch drip irrigation significantly increased the water use efficiency of sugar beet.Aims at getting high yield(≥6000kg hm2)and high quality(sugar content:15.3%-21.0%)root,irrigation level should reach 3426-3600m3/hm2 and 139-177kg/hm2 of N fertilizer.
