| Abstract: | Field experiments with single-crop late-maturing rice varietyXiushui 123were carried out in order to study the effect of slow-release fertilizer on direct-seed rice.The experimental results showed that compared with conventional chemical fertilizer application,application of slow-release fertilizer could significantly increase the rice yield by 3%- 6%,the utilization rate of fertilizer by 4 - 5 percentage points and the economic benefit by 219.0-327.9 yuan/hm~2. |
