摘要
为探索新技术、新材料的应用效果,研究了肥料增效与控释技术对水稻的生育性状、产量、品质以及氮肥利用率的影响。结果表明:采用肥料增效和控释技术能促进水稻生长发育、提高水稻产量和氮肥利用率。特别是在减施氮肥30%的条件下,采用肥料增效和控释技术的处理均比常规施肥增产,这说明通过新技术、新材料的应用,在保证水稻不减产的条件下减少化肥施用是完全可行的。
The effects of fertilizer efficiency and controlled-release technology on rice in black soil were researched to explore the application effect of new technology and new materials.The result showed that the technology could promote the rice growth,increase the rice yield and fertilizer-N use efficiency.The rice yield increased on reducing nitrogen fertilizer 30% of conditions because of the technology.It showed that to use the advanced technology and materials could guarantee the rice yield on reducing nitrogen fertilizer.
