用“中浙优10号”晚稻品种在漳平市新桥镇珍坂村进行肥效试验,本次试验表明,在一定的范围内,氮肥、磷肥和钾肥都可以使晚稻的产量增加,其增产率分别为18.1%、2.9%和4.7%。氮肥和钾肥对晚稻产量的增产影响大于磷肥,氮素是本试验影响晚稻产量的最大限制因子,建议在本试验的晚稻区域,应施好氮肥,适量施用磷钾肥。
The trial of fertilizer efficiency of “Zhongzheyou 10” “late rice” in Zhenzhang Village, Xinqiao Town, Zhangping City showed that within a certain range, nitrogen, phosphate and potassium fertilizers could increase the yield of late rice, Rates were 18.1%, 2.9% and 4.7% respectively. Nitrogen and potassium fertilizers had a greater effect on the yield increase of late rice than that of phosphate fertilizer. Nitrogen was the most limiting factor affecting the yield of late rice in this experiment. It is suggested that nitrogen fertilizer should be applied and the appropriate amount of phosphorus and potassium fertilizer should be applied in the late rice region of this experiment.
