牡蛎类土壤调理剂对设施番茄酸化土壤化学性质及果品质量的影响

Effects of oyster shell soil amendment on fruit quality and soil chemical properties in greenhouse tomato acidic soils

为探讨牡蛎类土壤调理剂对设施番茄生产的可能性,以期确定土壤调理剂改良设施番茄酸化土壤的合理用量,采用田间小区试验,研究酸化土壤施用土壤调理剂对设施番茄产量、品质及土壤pH值的影响。结果表明,酸性土壤施用牡蛎类土壤调理剂可获得增产,其中SC50处理下的产量较高,比对照增产16.54%。在常规施肥的基础上施用牡蛎类土壤调理剂,促进了番茄的生长发育,盛果期番茄单果重和果实中番茄红素有所提高。牡蛎类土壤调理剂能明显增加土壤pH值。综合比较不同剂量的牡蛎类土壤调理剂对设施番茄土壤pH值及果品质量的影响可知:土壤调理剂用量在50 kg/667m2表现最佳。

In order to explore more possibilities in the oyster shell soil amendment to greenhouse tomato production and confirmed the feasible application dosage, this paper confirmed the feasible application dosage and method. The field plot experiment was conducted to study the the effects of soil amendment on the yield, quality and soil p H of greenhouse tomato.The greenhouse tomato yield in acidified soil applied with oyster shell soil amendment was almost increased. Under the application of oyster shell soil amendment, the greenhouse tomato yield of treatment SC50 was higher, and it was 16.5 %higher than that in the control group. Under the application of conventional fertilization and oyster shell soil amendment, the growth and development of tomato plants were improved, and single fruit weight and lycopene concentration in mature tomato were increased. The application of oyster shell soil amendment significantly increased soil acidity. Comprehensively considering the effects of different treatments on the greenhouse tomato growth and development, the level of 50 kg/667m2 soil power was the best.
