| 摘 要： | 采用小区试验的方法,研究不同水分条件对地膜覆盖甘蓝产量和水分利用效率的影响。结果表明:只在结球前期浇1水(T4)可比对照(T1)节水39.75 mm,增产8.77%,水分利用效率提高23.25%,而叶球的干物质高于对照,但与对照无明显的差别;地膜覆盖条件下浇3水(T2)和不浇水(T5)都不利于产量形成,达不到节水、高产的目标。说明在坝上地区的甘蓝栽培中,适时和适量的灌溉(T4),可达到高产、高效和节水的目的。 |

| Abstract: | Effect of different water conditions on yield and water use efficiency of cabbage under plastic film mulch were studied.The results showed that the yield of T4 treatment can be increased 8.77%,water was saved 39.75 mm,water use efficiency was increased 23.25%.But dry weight of head were superior to that of the constrast(T1) with no significant difference.Excessive irrigating(T2) or no irrigating(T5) could not save water,achive high yield and improve economic benefit. |
| Keywords: | Cabbage water condition water use efficiency yield |
