Study on zinc status in high-yielding rice plants

摘要

The experimental results indicated that the relationship between the quantity of Zn accumulated in rice plants and the treatment factors could be fitted into internal logistic model. The quantity of Zn accumulated in the high-yielding plants was more than that in the low-yielding plants. In general, there were suitable average accumulation rate, maximum accumulation rate and it's emerging time, and the quantity of Zn in high-yielding rice plants. Losing nutritive distribution equilibrium of Zn might be an internal factor to decrease grain yield of the plants.
