Effects of Controlled-release Fertilizer on Growth and Yield of Machine Transplanted Rice

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。

Abstract: 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 application of conventional fertilization, but had significant differences with one time application of conventional fertilization.

Key words: machine transplanted rice, controlled-release fertilizer, tiller, chlorophyll, yield
