Absorption of nutrients by Rice at different growth stages

Last Updated: 2024/11/05, The absorption of nutrients in different growth stages of rice varies greatly with different types. The growth period of double cropping rice is short, especially the vegetative growth period in the field is shortened, and the vegetative growth and reproductive growth overlap shortly after transplanting. That is, panicle differentiation began at the same time of tillering in the field, and entered the peak tillering stage in the process of panicle differentiation, so a prominent fertilizer absorption peak was formed at 2-3 weeks after transplanting, and two fertilizer absorption peaks were formed for single-cropping rice at 2-3 weeks and 7-9 weeks after transplanting. The absorption rate of all kinds of nutrients by rice reached before heading.

The absorption rate of all kinds of nutrients by rice reached the maximum before heading, and then decreased. Among all kinds of nutrients, the absorption rate of nitrogen, phosphorus and potassium was the fastest and reached the maximum about 20 days before heading, while the absorption of silicon reached the maximum later.
