基于蛙稻生态种养模式氮肥运筹对水稻农艺性状及产量的影响
Effects of nitrogen application on agronomic traits and yield of rice based on eco-planting and breeding of rice and frog model
摘要
Abstract
Under the conditions of eco-planting and breeding of rice and frog,the effects of different nitrogen ratios of basic tillering fertilizer and panicle fertilizer on the major agronomic traits and yield of rice were studied.The results show that when the total amount of nitrogen was 300 kg/hm2 ,improving the nitrogen ratio of basic tillering fertilizer and panicle fertilizer could promote the plant height,tiller and effective panicle number of rice,but had negative effects on total grain number,grain number and 1 000-grain weight.When the nitrogen ratio of basic tillering fertilizer and panicle fertilizer was 7∶3,the spike rate of was the highest,reaching 68.9%,and that of the treatment 6∶4 was the lowest (63 .4%).The rice yield of treatment 7∶3 was the highest,reaching 1 1 464.1 kg/hm2 ,and the yield was extremely significantly higher than other treatments,there was no significant difference in yield between the other 3 treatments.Comprehensive considering the test results,the appropriate nitrogen ratio of basic tillering fertilizer and panicle fertilizer was 7∶3 .关键词
