中文摘要	为了探明新疆旱区不同滴灌频次下春油菜根系生长和产量性状,以新油17号为参试材料,设4个灌水频次( W_1,W_2,W_3,W_4 )进行田间试验。结果表明:灌水频次由W_4(苗期+现蕾期+花后10d+终花期)减少至W_1(不灌水)时生育期相应缩短2~ 5d;不同滴灌频次对含水率影响W_4 >W_3 >W_2 >W_1,由W_1增加至W_4对0 ~ 60cm土壤含水率影响较大、60~ 100cm土壤含水率影响较小,0~ 40cm根干重增加显著,根活力值相对较高,各器官干物质积累量也呈逐渐增加的趋势;由W_4减少至W_1油菜产量由3026.5 kg·hm~(-2)降至1219.1 kg·hm~(-2),农艺性状也相应降低,差异显著; W_3处理油菜产量为2749.1 kg·hm~(-2)与W_4无显著差异性。综上,设置现蕾期和花后10d两次滴灌对产量性状及产量影响较小,是目前可行的节水高产的高效利用模式。
英文摘要	In order to explore the root growth and yield-related traits of spring rapeseed under different drip irrigation frequencie in arid region in Xinjiang. Xinyou No.17 was chosen for experimental material. There were four frequencies of drip irrigation ( W_1,W_2,W_3 and W_4 ) for field experiments. The results showed that the growth stage reduced 2~5 days since frequencies of drip irrigation from W_4 ( seedling,squaring,post-flowering 10 d and final flowering stage) reduced to W_1 ( no drip irrigation) . Furthermore,the effect of different frequencies of drip irrigation on the moisture content ranked W_4>W_3>W_2>W_1 . With the increased frequencies of drip irrigation from W_1 to W_4, the effect on moisture content of soil was more significant in 0 ~ 60 cm than those in 60 ~ 100 cm level. The dry weight of roots,root activity and dry matter accumulation had a growing trend in 0 ~ 40 cm level. Moreover,the yields of spring rapeseed reduced from 3026.5 kg·hm~(-2) to 1219.1 kg·hm~(-2) with the decreasd frequencies of drip irrigation frequencie from W_4 to W_1,while the main agronomic traits also declined with significant differences. In addition,there was no obvious yield difference between W_3’s 2749.1 kg·hm~(-2)and W_4 . Taken together,it was little effect on yield-related traits and yields of spring rapeseed treating with drip irrigations at squaring stage and 10 d post-flowering. This could be a viable effective model for water-saving and high-yield spring rapeseed production.
