摘要:

为了探究聚天冬氨酸镁(PASP-Mg)对菠菜生产的影响,本研究以菠菜为试验材料,系统分析了不同施用量(1.50、2.25、3.00 kg·hm-2)PASP-Mg对菠菜生长、产量、品质和养分积累的影响。结果表明:在试验施用量范围内,PASP-Mg对菠菜生长未表现出抑制作用,所有处理均具有显著(p<0.05)增产效果,增幅为10.20%~11.10%。在品质方面,施用PASP-Mg可显著降低菠菜中的硝酸盐含量,降幅为9.28%~13.11%,同时显著提高叶绿素、维生素C及可溶性蛋白含量,增幅分别为19.57%~23.91%、12.32%~17.90%和14.34%~22.13%。在养分积累方面,施用PASP-Mg可显著增加氮、磷、钾积累量,增幅分别为8.29%~10.35%、9.53~18.75%、8.58%~9.36%,表明施用PASP-Mg可增强养分利用效率。综合施用成本、菠菜产量与品质,确定本试验条件下PASP-Mg的适宜用量为2.25 kg·hm-2,可以实现增产、提质的目标。

Abstract:

In order to explore the effects of polyaspartic acid-magnesium (PASP-Mg) on the production of spinach, this study used large-leaf spinach as the experimental material and systematically analyzed the impacts of different application rates (1.50, 2.25, 3.00 kg·hm-2) of PASP-Mg on its growth, yield, quality, and nutrients accumulation. The results indicated that within the tested application rates, PASP-Mg did not exhibit any inhibitory effects on spinach growth. All treatments with PASP-Mg demonstrated significant (p<0.05) yield-increases by 10.20%-11.10%. In terms of quality, the application of PASP-Mg significantly reduced nitrate content in spinach by 9.28%-13.11%, while significantly increased chlorophyll, vitamin C, and soluable protein content by 19.57%-23.91%, 12.32%-17.90%, 14.34%-22.13%, respectively. In terms of nutrients accumulation, the contents of nitrogen, phosphorus, and potassium were significantly increased by 8.29%-10.35%, 9.53%-18.75% and 8.58%-9.36%, respectively, with PASP-Mg application. Based on the comprehensive analysis of spinach quality and yield and application cost, the optimal application rate of PASP-Mg under the experiment conditions was 2.25 kg·hm-2, which could achieve the goals of increasing yield and improving quality.
