以24个冬小麦品种(系)为材料,在不同的灌水处理下,研究了产量、产量构成因素和抗旱指数的品种差异。结果表明,灌水处理间与品种间产量差异均极显著,灌水与品种互作差异显著。2水处理产量高于4水。石4185,冀 5579,石麦12等19个品种2水处理产量高于4水,多丰2000,师栾02-1,良星99等5个品种4水产量高于2水。分别以2水处理和4水处理下的产量作为水地产量计算抗旱指数,得出抗旱型,不抗旱型和中间型比例分别为4．2％, 29．2％,66．6％和20．8％,20．8％,58．4％。综合分析认为石麦12,冀5579和石新618等产量和节水综合性状较好的品种更适于节水栽培。
Twenty-four winter wheat cultivars (lines) were used to study the differences in yield, yield components and drought resistance index under different irrigation treatments. The results showed that there was a significant difference in yield between irrigation treatments and varieties, and there was significant difference between irrigation and variety. 2 water treatment output is higher than 4 water. Stone 4185, Hebei 5579, Shimai 12 and other 19 varieties of 2 water treatment output is higher than 4 water, Duofeng 2000, division Luan 02-1, Lonestar 99 and other 5 varieties 4 water yield is higher than 2 water. The drought-resistance index, drought-resistant index and intermediate index were calculated as 4.2%, 29.2%, 66.6% and 20%, respectively, using the yields of 2-water treatment and 4-water treatment as water yield. .8%, 20.8%, 58.4%. The comprehensive analysis shows that the varieties with better comprehensive yield and water-saving characteristics, such as Shimai 12, Ji 5579 and Shi Xin 618, are more suitable for water-saving cultivation.
