Effects of different cultivation measures on nitrogen utilization efficiency of basal fertilizer and rice yield
To evaluate the effects of different cultivation measures on the nitrogen utilization efficiency of basal fertilizer and rice yield base fertilizer,the rice variety Weiliangyou 8612 was used as the experimental material,and the rice yield,plant nitrogen absorption and conversion rate,and soil enzyme activity under different cultivation measures were analyzed using 15N labeling and tracing technology.The results showed that improving irrigation management and optimizing fertilization strategies were beneficial for increasing nitrogen accumulation and absorption in rice plants,and increasing yield.Among them,the comprehensive management measure of light dry wet alternation irrigation combined with organic fertilizer(ZGC-3)had the better effect.In addition,comprehensive management measures are beneficial for improving soil enzyme activity and enhancing soil biochemical activity.The study confirmed the effectiveness of comprehensive cultivation management strategies in improving rice yield and nitrogen fertilizer utilization efficiency,as well as reducing environmental impact.
