摘要
以日光温室膜下滴灌方式种植的番茄品种“佳西娜”为研究对象,开展4个水分梯度的灌溉控制试验,对试验中番茄的根系生长情况和番茄果实进行采样并利用主成分分析法对番茄的产量、水分利用效率、主要品质因子进行综合分析,研究了不同灌溉水平对番茄生长生理参数、产量以及品质的影响,以期寻求设施番茄膜下滴灌调节下的最优灌溉制度。结果表明:番茄的主要根系吸水深度在0~60 cm且随着灌水量的降低,根长、根表面积、根体积降低。春、秋茬番茄全生育期充分灌水下的耗水量、产量、水分利用效率分别是297.56 mm、5.42 t·hm^(-2)、15.59 kg·m^(-3)和230.65 mm、2.97 t·hm^(-2)、8.77 kg·m^(-3),随着灌水量的减少,水分利用效率和品质呈上升趋势,而产量逐渐减少;综合考虑番茄的产量、水分利用效率、主要品质因子,日光温室膜下滴灌番茄的灌水量为55%ET_(0)时为最优灌水量。
Gasilla tomatoes grown under film drip irrigation in solar greenhouse were used as research objects.Four irrigation control experiments were carried out.Root growth and tomato fruit were sampled in the experiment,and the yield,water use efficiency and main quality factors of tomato were comprehensively analyzed by principal component analysis.The effects of different irrigation levels on growth physiological parameters,yield and quality of tomato were studied,in order to find the optimal irrigation system under mulched drip irrigation.The results showed that water uptake depth of tomato roots ranged from 0 cm to 60 cm.With the decreases of irrigation amount,root length,root surface area,and root volume decreased.The water consumption,yield,and WUE of tomato under full irrigation during the whole growth period of spring and autumn were 297.56 mm,5.42 t·hm^(-2),15.59 kg·m^(-3) and 230.65 mm,2.97 t·hm^(-2),8.77 kg·m^(-3),respectively.With the decreasing of irrigation amount,WUE and quality increased,while yield decreased.Considering the yield,WUE and main quality factors of tomato,the optimal irrigation amount of drip irrigation under film was 55% ET_(0) in solar greenhouse.
