针对扬州地区春大棚番茄生产中灌水量尚未明确的问题,以番茄主栽品种“金冠一号”为试材,根据番茄作物所需水和各地生产中灌水经验,以及当地土壤和气候条件,研究了不同667m2灌水量(60、90、120、150、180m3对番茄产量和品质的影响。结果表明:灌水量为120m3的番茄的平均单果质量和单株产量最高;667m2灌水量为90m3的番茄的可溶性固形物、可溶性糖、糖酸比和番茄红素含量最高;因此,120、90m3可分别作为扬州地区春大棚番茄高产量、高品质的灌水量指标。
Aiming at the problem that the irrigation quantity of tomato production in spring canopy in Yangzhou is not yet clear, the main tomato variety “Golden Delicious No.1” was used as the test material. According to the irrigation water requirement of tomato crop and its production in different places, as well as the local soil and climatic conditions (60,90,120,150,180m3) on the yield and quality of tomato were studied.The results showed that the average fruit weight per plant and yield per plant of tomato with 120m3 irrigation was the highest.The irrigation volume of 667m2 was 90m3 Soluble solids, soluble sugar, sugar and acid ratio and lycopene content of tomato were the highest. Therefore, 120 and 90 m3 could be used as indicators of high yield and high quality of spring tomato yield in Yangzhou.
