摘要
在施氮量相同的条件下,通过施用缓释肥,减少了机插稻的施肥次数,增加了机插稻的分蘖数、有效穗数和中后期叶绿素含量,但成穗率明显降低。缓释肥加1次尿素追肥处理的机插稻产量最高,但与常规分次施肥处理相比产量差异不明显,与常规一次性施肥处理产量差异达极显著水平。
In the same amount of nitrogen conditions, the tillers, effective panicles and chlorophyll content increased by the application of controlled-release fertilizer in the middle-later period, but the spike rate decreased significantly. The yield of controlled-release fertilizer and urea fertilizer treatment was the highest in machine transplanted rice, and it had no obvious differences with split appli- cation of conventional fertilization, but had significant differences with one time application of conventional fertilization.
