不同有机肥对沙培番茄生长发育及产质量的影响

Effects of Different Organic Fertilizers on Growth Development,Quality and Yield of Sand-culture Tomato

为沙培番茄合理施肥及优质高效生产提供理论依据,推进沙漠农业的发展,在沙培的日光温室条件下,研究不同有机肥施用对沙培番茄的生长发育及产质量的影响。结果表明:施用有机肥可促进番茄植株生长,提高果实品质及产量。其中,羊粪处理沙培番茄的产量最高,为15 410.65kg/667m^2,茎粗最大,硝酸盐含量最低;猪粪处理沙培番茄的产量其次,为13 924.86kg/667m^2,可溶性糖、可溶性固形物和VC含量最高。综合分析得出沙培番茄最适的有机肥是猪粪和羊粪。

The effects of different organic fertilizers on growth and quality of sand culture tomato are studied in a sunlight greenhouse to provide the theoretical basis for rational fertilization and high quality and efficient production of sand culture tomato and drive development of desert agriculture.Results:Applying organic fertilizer can improve growth,quality and yield of sand culture tomato.The yield of sand culture tomato applied with sheep manure is the highest(15410.65kg/667m2)and its stem diameter and nitrate content are the maximum and minimum respectively among four organic fertilizers.The yield of sand culture tomato applied with pig manure is up to13924.86kg/667m2and its soluble sugar,soluble solids and Vc content is the highest among four organic fertilizers.In conclusion,the optimum organic fertilizers for sand culture tomato are pig manure and sheep manure.
