广西贺州八步区水稻锌肥肥效小区试验研究

Plot Experiment of Zinc Efficiency in Paddy Field in Babu District,Hezhou,Guangxi

使用锌肥对水稻株高、叶色、千粒重、有效穗没影响,但可促进早立苗、早分蘖,对水稻产量有影响,使用15 kg/hm2农用硫酸锌可以增产768.0 kg/hm2增幅9.4%,增效2093.3元/hm2。

Zinc fertilizer doesn’t affect the rice plant height,leaf color,1000-grain weight,effective panicle,but can promote seedling standing and tillering early,and has influence on rice yield.Applying 15 kg/hm2 agricultural zinc sulfate can increase yield by 768.0 kg/hm2,representing 9.4 percent growth,and increase income by 2093.3 yuan/hm2.
