硫素与其他营养元素的交互作用对作物养分吸收、产量和质量的影响

养分平衡是养分管理的必要环节,对增加作物产量和提高品质具有重要的作用.本文综述了硫(S)素与其他营养元素之间的交互作用对作物养分吸收、产量和质量的影响.S 与N或Ca、 K、Zn之间交互作用对养分吸收和利用是协同的,而S 与Mg、Mo、Cu、、Se、Fe、Sb、Cd、B、Br之间交互作用对养分吸收和利用是拮抗的.然而,S 与 P或Se之间的交互作用对养分吸收和利用是协同还是拮抗取决于作物种类、生长阶段和养分的浓度.N、S配施可以促进蛋白质的合成,提高作物产量和品质.由于S素与其他营养元素之间存在的这种拮抗作用,因此施用S肥可以减轻污染土壤重金属对蔬菜的毒害作用或加剧缺S土壤上蔬菜B和Mo的缺乏.

Interaction Effects of Sulfur and Other Nutrients on Nutrient Uptakes, Yields, and Qualities of Crops

Balanced nutrition is an essential component of nutrient management and plays a significant role in increasing crop production and quality. This paper reviewed the interaction effect of S and the other nutrients on nutrient uptakes, yields, and qualities of crops. Interaction of S and N or Ca , K, Zn on the uptake and utilization of each other were synergistic effects, whereas interaction of S and Mg, Mo, Cu, Se, Fe, Sb, Cd, B, Br on those were antagonistic effects. However, synergistic effects or antagonistic effects between S and P or Se depent on plant varieties, growth periods, and concentrations of nutrients. Combined application of N and S improved protein synthesis and increases yields and qualities of crops. Application of sulfur fertilizer could reduce toxic effects of heavy metal elements in vegetables grown on polluted soils or induce serious deficiencies of B or Mo of vegetables on the soils with low S contents due to antagonistic effects between S and the other nutrients.
