摘要
通过正规玉米肥料试验,研究在草甸土区施用硫肥的效果。试验表明:在玉米上施用硫肥,能改善玉米的生育性状,穗粒数分别比对照多 15.0～32.1 个,千粒质量比对照多 3～6 g,增产 26.7～31.2 kg/667 m2,差异达到显著水平。同时,增加产值 34.72～33.92元 / 667 m2,经济效益明显。
Regular maize fertilizer experiments were conducted to study the effect of sulfur fertilization in meadow soil. The findings show that sulfur fertilization on maize can improve the growth of maize, resulting in more seeds than the control group, ranging from 15 to 30 each, and the thousand seed weight was 3～6 g heavier, the yield increased 26.7～31.2 kg / 667 m2., and the economic returns increased by 34.72～33.92 Yuan / 667 m2.
