不同灌溉方式对设施樱桃番茄生长及品质的影响

【目的】筛选樱桃番茄无土栽培的最佳灌溉方式,为设施无土栽培樱桃番茄的水肥精准管理提供理论依据。【方法】以高糖樱桃番茄为材料,椰糠为栽培基质,在环境条件一致的情况下,设置不同的灌水方式,测定番茄幼苗的株高、茎粗、叶面积、鲜重、干重、可溶性糖、可溶性蛋白、光合速率等指标,研究不同灌溉方式对设施无土栽培樱桃番茄形态、品质、产量及光合作用的影响。【结果】各处理对樱桃番茄生长、产量及品质的影响不尽相同,其中,滴灌与潮汐式灌溉相结合的灌溉方式处理的樱桃番茄果形指数、果实品质、光合参数、产量最佳,其各指标要优于滴灌与潮汐式的灌溉方式。【结论】滴灌与潮汐式灌溉相结合的灌溉方式最有利于无土栽培的樱桃番茄生长。

Effects of Different Irrigation Methods on Growth and Quality of Facility Cherry Tomatoes

【Objective】 To screen out the best irrigation method for screening soilless cultivation of cherry tomatoes with a view to providing a theoretical basis for the precise management of water fertilizer for soilless cultivation of cherry tomatoes. 【Methods】 With high-sugar cherry tomatoes as the experimental material, coconut bran as the cultivation matrix, different irrigation methods were set under the condition of consistent environmental conditions, and the effects of high plant height, stem thickness, leaf area, fresh weight, dry weight, soluble sugar, soluble protein, photosynthesis rate of different irrigation methods on soilless soil-cultivated cherry tomato morphology, quality, yield and photosynthesis were studied. 【Results】 The effects of each treatment on the growth, yield and quality of cherry tomatoes were different, among which, the cherry tomato fruit index, fruit quality, photosynthesis parameters and yield of the irrigation method combining drip irrigation and tidal irrigation were better than the drip irrigation and tidal irrigation methods. 【Conclusion】 The irrigation method combining drip irrigation with tidal irrigation is most beneficial to the growth of soilless cherry tomatoes.
