Cabbage is hi- and fat-tolerant vegetables. About 35 days after the general planting, the nitrogen, phosphorus, calcium and other elements and absorption of the plant reached the peak, while the potassium absorption peaked at 50 days. Before the peak value was reached, the uptake of the plant was basically linear with the growth period. Different growth stages of cabbage have different requirements for nutrient absorption. The absorption of nitrogen fertilizer was the highest at seedling stage and rosette stage, followed by phosphorus, while potassium was more at the ball stage. According to research, the absorption of nutrients for each ton of cabbage produced is: N3.5 kg, P2O 50.80 kg, K2O3.49 kg, and its absorption ratio is N: P2O5: K2O=1:0.3:1.1. Visible cabbage vegetables are vegetables that require more nitrogen and potassium. Cabbage is sometimes susceptible to calcium deficiency symptoms such as the tip of the tip of the leaf or the rot inside the leaf ball, which greatly reduces the quality of the product. Studies have shown that dry soils, excessive nitrogen fertilizers, and high salt content in the soil can inhibit the absorption of calcium in cabbage.
