摘要: 采用封闭式无机基质槽培智能循环供液系统,以番茄‘丰收’作为供试材料,探究一定时间内单株不同供液量对温室封闭式无机基质槽培番茄生长、产量和果实品质的影响。试验表明,T3(供液量4.5 L)有机酸和可溶性糖含量最高,与其他5组处理之间的差异均有统计学意义;T4(供液量6.0 L)株高、单果重、产量、可溶性固形物和Vc含量均高于其他处理,Vc差异较为明显,可溶性固形物各处理之间差异较小。定植135天,T4处理株高比最低株高处理T6高出24.4%;结果期,T4总产量和单果重分别高出T1处理29.0%和9.5%;T4处理Vc和可溶性固形物含量分别高出T1的34.3%和10%,T3处理有机酸和可溶性糖含量分别比T1高出 17.8%和27.1%。因此,过多和过少供液量均不利于温室槽培番茄生长产量的增加和果实品质的提高,供液量为每2 h单株供液量在4.5~6.0 L,番茄产量和品质两者兼优。

Abstract: Taking tomato ‘Fengshou’ as test material, an experiment was carried out with a system of enclosed inorganic substrate intelligent circulation trough supplying nutrition cyclically, in order to explore the effects of different amounts of nutrient supplying per plant in a certain period of time on greenhouse tomato growth, yield and quality. The results showed that T3 (amount of nutrient supplying was 4.5 L/plant) had the highest organic acid and soluble sugar content, and the difference among the other 5 treatments had statistical significance. T4 (amount of nutrient supplying was 6.0 L/plant) had higher plant height, weight per fruit, yield, soluble solids and Vc content, the difference of Vc content was more obvious, soluble solids had small differences among the treatments. When tomatoes grew 135 days, plant height of T4 was 24.4% higher than that of T6, which had the lowest plant height. In the whole fruit growth stage, the yield and weight per fruit of T4 was 29.0% and 9.5% higher than that of T1. Vc and soluble solids content of T4 were 34.3% and 10% higher than that of T1, the organic acid and soluble sugar content of T3 were 17.8% and 27.1% higher compared with that of T1. As a result, more and less amount of nutrient supplying was not conducive to increase the yield and improve the quality of greenhouse tomato. Both the yield and quality of greenhouse circulation trough tomato were better when the amount of nutrient supplying was kept between 4.5 to 6.0 L/plant in two hours.
