摘  要:
The effects of nitrogen, phosphorus and potasium applicationlevel, seed rate and transplanting density on the growth anddevelopmnet of rice plants were studied to find out nutrient statusin high-yielding rice plants and to increase grain yield by adequatefertilization. There was an equilibrium relawtionship among nutrientelements for high-yielding rice plant populations. The equilibrimindex of nutrient amount, content and distribution in hihg-yieldingrice plants should be generally greater than-2 but less than 2.
