低段密植基质袋培对设施番茄产量及品质的影响

Effects of Less Spike Close Density Bag Cultured on the Yield and Quality of Facility Tomato

为了使复垦、盐碱地及新建的设施得到快速利用,以基质袋和"GBS-傲兰六号"番茄为试材,研究了设施番茄在低段密植基质袋培不同模式下生物性状、产量及品质的变化,以期筛选出适宜天津地区的番茄高产优质低段密植袋培模式。结果表明:袋培番茄增加密度50%保留2段果穗(G1)、增加密度30%保留3段果穗(G3)处理与基质常规栽培和土壤常规栽培相比,番茄株高平均增加4.63%～27.37%;茎粗增加4.65%～20.64%;叶绿素含量增加10.10%～22.79%;番茄单果重增加11.32%～17.12%;产量提高29.09%～56.99%;可溶性总糖含量增加13.54%～16.91%,可滴定酸含量增加7.05%～7.51%,维生素C含量增加12.42%～21.28%;硝酸盐含量降低7.14%～17.10%。

For the aim of utilize the reclamation land,saline land and new build facilities as soon as possible,with medium bag and ＇GBS-Aolam No. 6＇ as materials, the tomato biological characters, yield and quality under a less spike close density bag cultured pattern which suitable for Tianjin area investigated. The results showed that, compared with conventional substrate and soil culture, the plant height, stem diameter, chlorophyll increased by 4. 63% -27. 37%, 4. 65 % -20. 64 % and 10. 10 % -22. 79 % under pattern G1 （bag cultured tomato increase density 50 % reserve 2 period of grain） and G3（bag cultured tomato increase density 30% reserve 3 period of grain）. The single fruit weight and yield also over 11.32%-17. 12% and 29. 09-56. 99% than conventional substrate and soil culture. The quality of tomato, such as total soluble sugar,titratable acid and vitamin C content also increased by 13. 54%-16. 91%,7. 05%--7. 51% and 12. 42%-21.28% respectively,and the content of nitrate decreased by 7. 14-17. 10%.
