为探究增效磷尾矿粉对作物生长、品质和土壤理化性状的影响,以温室地栽小番茄为试验对象,开展了试验研究。试验共设置5个分别施用增效磷尾矿粉5.0、10.0、15.0、20.0、25.0 g/株作为底肥的处理(L1~L5),以不施增效磷尾矿粉的处理为对照(L0),测定了各处理的小番茄的生长、品质和土壤理化性状等指标。结果表明:L1~L5处理的小番茄的株高、花朵数、单株果实数及单株果实质量均高于L0处理的;L1~L5处理的小番茄果实中可溶性糖、蛋白质和维生素C的含量均高于L0处理的,而有机酸含量均低于L0处理的;L1~L5处理的土壤中有效磷、交换性钙、交换性镁的含量及pH均高于L0处理的。增施增效磷尾矿粉作底肥可促进小番茄的生长,提升果实品质,并改善土壤理化性状。
To investigate the effects of synergistic phosphorus tailings powder on crop growth, quality, and soil physical and chemical properties, a study is conducted using greenhouse ground-planted cherry tomatoes as the test subject. Five treatments (L1-L5) are set up with basal applications of synergistic phosphorus tailings powder at rates of 5.0, 10.0, 15.0, 20.0, and 25.0 g per plant, respectively. A treatment without the application of synergistic phosphorus tailings powder is used as the control (L0). Growth and quality indicators of cherry tomato, as well as soil physical and chemical properties, are measured across different treatments. The results show that plant height, number of flowers, number of fruits per plant, and fruit weight per plant in treatments L1-L5 are higher than those in the L0 treatment. The contents of soluble sugar, protein, and vitamin C in cherry tomato fruits in treatments L1-L5 are higher than those in the L0 treatment, while the organic acid content is lower. The soil available phosphorus, exchangeable calcium, exchangeable magnesium contents, and pH in treatments L1-L5 are higher than those in the L0 treatment. Applying synergistic phosphorus tailings powder as a basal fertilizer can promote the growth of cherry tomato plants, improve fruit quality, and enhance soil physical and chemical properties.
