采用土培试验研究了不同氮钙营养配合施用对菠菜产量、钙含量以及土壤钙含量的影响。结果表明,在本试验条件下,当氮钙用量分别为0.2 g/kg和0.3 g/kg时,菠菜的生物量最高,叶片钙含量最高,土壤水溶性钙、交换性钙和有效态钙含量较高。 Soil culture experiments were conducted to study the effects of different nitrogen and calcium nutrients on spinach yield, calcium content and soil calcium content. The results showed that the biomass of spinach was the highest, the content of calcium in leaf was the highest under the conditions of 0.2 g / kg and 0.3 g / kg respectively, and the content of soil water-soluble calcium, exchangeable calcium and available calcium Higher.
