苎麻是多年生纤维作物,对钾和氮素吸收最多,且种植当年与壮令期在植物营养、生理、栽培管理等方面有明显不同。因此有必要研究不同氮肥水平下钾肥用量对苎麻产量和品质的影响,并探索麻地土壤钾素平衡状况,为大田生产当年种麻获得丰产增收提供合理施肥依据。 Ramie is a perennial fiber crop that absorbs the most potassium and nitrogen, and there are significant differences in plant nutrition, physiology and cultivation management between the year of planting and the order of planting. Therefore, it is necessary to study the effect of potassium fertilizer application on the yield and quality of ramie at different levels of nitrogenous fertilizer and to explore the status of potassium balance in the soil of marijuana so as to provide a reasonable fertilization basis for planting high yield and increasing yield of seedling in the field.
