Answer: Daylily fertilization requires sufficient Winter fertilizer (basal fertilizer), early application of seedling fertilizer, heavy application of manure fertilizer, and supplementation of bud fertilizer. Every year before Spring emergence, the field is cultivated once, and the fast-acting fertilizer is applied once. Miao fertilizer should be applied sooner rather than later, and should be applied when daylily begins to sprout, applying 10 kg of urea, 30 kg of superphosphate, and 8 kg of potassium sulfate. Before the pumping, we carried out shallow middle tillage, and applied a second quick-acting fertilizer, which was called booster fertilizer. This period requires a lot of fertilizer, and should be applied when the calyx starts to be drawn out. Apply 15 kg of urea, 30 kg of superphosphate, and 10 kg of potassium sulfate per mu.
