不同滴灌量对日光温室番茄生长、产量和品质的影响

Effects of Different Drip Irrigation Quantities on Development、Yield and Fruit Quality of Tomato Growth in solar Greenhouse

为明确京郊日光温室番茄滴灌条件下适宜的灌溉量,以番茄‘欧盾’为试验材料,研究不同滴灌量对其生长、产量和水分生产效率的影响。结果表明:T1处理产量最高达到113 700 kg/hm2,较对照增产6.5%,果实品质有所提高,水分生产效率提高29.8%;其次是T2处理,较对照增产3.0%,水分生产效率提高54.4%;T3处理较对照产量有所降低。综合产量、品质和水分生产效率等指标,在该试验条件下,单次灌溉24 mm(T1处理)是温室番茄滴灌条件下较适宜的灌溉量。

In order to explore the appropriate drip irrigation quantities of Beijing solar greenhouse tomato, the effects of different drip irrigation quantities on the growth, yield and water use efficiency of solar greenhouse tomato “oudun” were analyzed. Results showed that the yield of the T1 was 113 700 kg/hm2, which was higher than other three treatments. Compared with traditional drip irrigation quantities, yield of treatment T1 increased by 6.5%, fruit quality improved, and water use efficiency increase by 29.8%. Compared with traditional drip irrigation quantities, yield of T2 treatment increased by 3.0%, and water use efficiency increased by 54.40%. The yield of the T3 was lowest. By analyzing the properties of tomato yield, fruit quality and water use efficiency, in this experiment T1 treatment is the optimal irrigation quantity for greenhouse tomato.
