| 中文摘要: |
| 为确定适宜引黄灌区枸杞灌溉生产模式，在甘肃省景秦县玉杰枸杞种植园进行了秸秆覆盖和灌水试
验研究。试验以三年生宁杞1号为研究对象，设秸秆覆盖下灌溉定额7 840 m3·hm-2(T1)、6 270 m3·hm-2(T2)、4 705 m3·hm-2(T3)处理，无覆盖措施、灌溉定额为7 840 m3·hm-2(CK)处理为对照，测定和分析了新梢生长量、耗水量、产
量和水分利用效率等指标。结果表明：(1)新梢生长量随灌溉定额的增大而增大，T1处理的新梢生长量显著高于
(P<0.05)其余处理，T3和对照CK处理差异不显著(P>0.05)；(2)灌溉定额与枸杞干果产量没有呈现出正相关，
产量大小依次为：T2>T1>CK>T3，其中T2处理达到2 598.32 kg·hm-2；(3)水分利用效率以T2处理最高，为2.32 kg·mm-1·hm-2，依次较CK、T1和T3处理提高了52.6%、24.7%和25.4%，差异显著(P<0.05)；(4)T2处理的耗水量(1 121.36 mm)显著低于(P<0.05)CK和T1处理。灌溉定额为6 270 m3·hm-2且采取秸秆覆盖处理是一种最优的枸杞节水增产水分管理模式。 |

| In order to determine a suitable irrigation mode for Lycium in Yellow River irrigation area, four treat-ments of straw mulching and irrigation were tested on Lycium of three-year old, Ningqi 1,in Jingtai yujie plantation. CK as control, had no straw mulch coverage with an irrigation quota of 7 840 m3·hm-2.T1 to T3 treatment had straw mulch, and irrigation quota were7 840 m3·hm-2, 6 270 m3·hm-2, and 4 705m3·hm-2 respectively. Shoot growth, water consumption, yield, and water use efficieney were measured and calculated. The results showed that:(1)Lycium shoot growth increased with rise of irrigation quota, shoot growth of Lycium in T1 treatment was signifieantly higher(P<0.05)than in other treatments. There no significant difference between CK and T3(P>0.05);(2)There were no positive correlation between irrigation quota and dried Lycium production. The order of Lycium yield with different treat-ments was T2>T1>CK>T3. T2 treatment gained the highest yield, reached 5 168.39 kg·hm-2;(3)T2 treatment gained the highest water use efficiency, which was 4.61 kg·mm-1·hm-2. Compared to CK、T1 and T3 treatment, water
use efficiency was increased 52.6%, 24.7%and 25.4%, respectively.(4)Water consumption in T2 treatment reached 1 121.36 mm, which was significant lower than in CK and T1 treatment; In conclusion,T2 treatment, straw mulch combined with the irrigation quota of 6 270 m3·hm-2, was the best mode for enhance the Lycium yield and for water-saving irrigation. |
