生物能尿素对水稻生长发育和产量的影响

摘要

[目的]改进氮肥投入方式,促进水稻增产增效.[方法]以光明粳2号、2645品系为材料进行大田试验,研究生物能尿素与传统尿素对水稻生长发育和产量的影响.[结果]生物能尿素对于提高水稻产量具有一定的作用,产量增加的主要原因是千粒重和每穗粒数提高,一次枝梗数和二次枝梗数与常规尿素相比均有不同程度的增加,并且能够促进水稻前期分蘖以及植株高度.[结论]生物能尿素处理各方面均优于常规尿素处理,在生产上可以进行推广使用.%[Objective] To improve application method of nitrogen fertilizer,promote yield and profits of rice.[Method] Field trials were carried out,we chose Guangminggeng 2 and strain 2645 as materials to study the effect of different kinds of urea on growth and yield of rice.[Result] Bio-energy urea had good effect on increasing rice yield,with the promotion of 1 000-grain weight and number of grain per panicle.Compared with common urea,the rice under bio-energy urea had more primary and second branch number,the tiller numbers of early growth and plant height both improved.[Conclusion] The bio-energy urea is superior to common urea,we can popularize it in field production.
