| 【目的】明确滴灌枸杞适宜的灌溉制度。【方法】以1 a生宁杞1号、5号、7号、0901、0909为试验材料，分别设置5个滴灌水平，依次为5 100 m3/hm2（W1）、4 350 m3/hm2（W2）、3 600 m3/hm2（W3）、2 850 m3/hm2（W4）、2 100 m3/hm2（W5），以常规灌水量5 100 m3/hm2为对照（CK），研究了不同滴灌量对植株生长、产量和品质的影响。【结果】不同滴灌量对不同枸杞品种株高、茎粗、SPAD等指标及产量、品质的影响较大。对于宁杞1号， W5处理极显著地提高了枸杞产量（p<0.01），平均增产60.71%，株高、茎粗、SPAD值增长迅速，总糖、总酸质量分数比CK提高3.82%、9.19%；对于宁杞5号， W5处理SPAD值及品质与CK相比显著增加，增产36.56%，果实品质最优；对于宁杞7号， W2处理甜菜碱及总糖质量分数量最高，产量与CK差异极显著（p<0.01），三者比CK及其他处理平均增加36.10%、38.71%和6.27%；对于宁农0901，W3处理有效促进了株高、茎粗及叶绿素SPAD的增加，增产52.19%；对于宁农0909， W4处理各项指标与CK差异虽然不显著，但产量、品质整体优势较明显。【结论】不同品种枸杞应设置不同的灌溉制度，适宜的滴灌量可以有效改善枸杞生长状况，提高枸杞产量，达到节水调质的目的。 |

| Abstract: |
| 【Objective】 Irrigation schedule controls growth and quality of crops and the objective of this paper is, by taking wolfberry as an example, to investigate how its growth and fruit quality respond to the amount of drip irrigation. 【Method】 We used the varieties of Ningqi No.1, No.5, No.7, No.0901, No.0909 in the experiment, and tested five irrigation rates: 5 100 m3/hm2 (W1), 4 350 m3/hm2(W2), 3 600 m3/hm2(W3), 2 850 m3/hm2(W4), 2 100 m3/hm2(W5), with conventional irrigation with 5 100 m3/hm2 as the control (CK). For each treatment, we measured plant growth, as well as the yield and quality of the fruits. 【Result】 The results showed that the effects of different drip irrigation on the growth indexes, such as plant height, stem diameter and chlorophyll SPAD and yield and quality of different wolfberry varieties were significantly. For No.1, suitable drip irrigation volume was W5 treatment. Compared with CK, the yield was significantly increased 60.71% (P<0.01). The plant height，stem diameter and chlorophyll SPAD growed rapidly, the total sugar and total acid mass fraction increased by 3.82% and 9.19%. For No.5, suitable drip irrigation volume was W5 treatment. The plant height, chlorophyll SPAD and quality were significantly increased (P<0.05) compared to CK, yield was increased 36.56%, and fruit quality was optimal. For No.7, suitable drip irrigation volume was W2 treatment. The content of betaine and total sugar was the highest, and the yield was significantly different with CK; The content of betaine,total sugar and yield increased by 36.10%, 38.71% and 6.27% compared to the average of CK and other treatments. For No.0901, suitable drip irrigation volume was W3 treatment. It effectively promoted the increase of plant height, stem diameter and chlorophyll SPAD, and the yield was increased 52.19%. For No.0909, suitable drip irrigation volume was W4 treatment. Although the indicators were not significant differences compared with CK, but the overall advantage of yield and quality was better. 【Conclusion】 Different varieties of wolfberry responde differently to irrigation amount, and choosing a suitable drip irrigation schedule for each variety can effectively improve its growth and yield, achieving water-saving and quality-improving simultaneously. |
