为研究安全的蔬菜施肥技术,通过不同质地土壤的田间试验,研究不同氮、钾质量配比对小白菜产量和品质的影响。结果表明,在固定施磷水平的基础上,在不同质地的土壤上,小白菜对氮、钾质量配比有不同的效应,氮、钾合理配施可使蔬菜高产优质;所施氮的形态,对小白菜硝酸盐含量有显著的影响。
In order to study the safe technology of vegetable fertilization, the effects of different nitrogen and potassium ratios on the yield and quality of Chinese cabbage were studied through field experiments on different soil soils. The results showed that on the basis of the fixed application of phosphorus, Pakchoi had different effects on the ratio of nitrogen and potassium on the soil with different textures. The rational application of nitrogen and potassium could make the vegetables produce high quality and high yield. , The nitrate content of cabbage had a significant impact.
