中文摘要：
通过3因素2水平正交试验,研究了宁夏非耕地温室春茬番茄滴灌条件下不同防渗处理、水质、灌水定额的最优组合。结果表明,番茄品质、光合作用和总产量等的主要影响因素是防渗措施,其次是灌溉水质和灌水定额。塑料薄膜防渗处理保水效果好,提高了番茄的产量和水分利用率,使番茄果实中Vc和可溶性糖增加;全生育期灌水定额4 260 m3/hm2时,番茄果实的糖酸比较高,水分利用效率较6 690 m3/hm2灌水定额提高了21.93%~26.92%。灌溉水质对番茄产量和品质等有影响但均未达到5%显著水平。塑料薄膜防渗下,使用微咸水与净化水混合灌溉且全生育期灌水定额4 260m3/hm2为最佳灌溉制度。
英文摘要：
Through the orthogonal tests with 3factors and 2levels,the optimal combination of seepage control,water quality and irrigation quotain of tomato at non-cultivated land greenhouse under drip irrigation in Ningxia were studied.The results showed that the main factor of the quality of tomato,photosynthetic indexes and the total yield was the anti-seepage measure,followed by quality of water and quota.Water holding effect was the optimal,the yield,water use efficiency of tomato,Vc and soluble sugar content in fruit were improved under plastic film seepage treatment.Sugar acid ratio of tomato was improved and water use efficiency increased by 21.93%~26.92% with irrigation quota of 4 260m3/hm2 compared with irrigation quota of 6 690m3/hm2.The irrigation water quality had impacts on yield and quality of tomato,but they were not significant at 5%level.Under anti-seepage measure of plastic film,mixed water irrigation of brackish water and purified water with irrigation quota of 4 260m3/hm2 was the best irrigation system.
