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

Le résumé fourni par la source

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 2period of grain) and G3(bag cultured tomato increase density 30%reserve 3period 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%.
