硫基复合肥在玉米上的试验示范效果

硫是作物生长发育不可缺少的营养元素,合理施用硫肥已经引起重视。以忻府区、原平市、定襄县作为硫基复合肥试验示范县,在玉米上进行了系统的小区试验和较大面积的示范推广。结果表明,在小区试验中,施用硫肥处理的玉米产量与当地测土配方施肥处理的产量相比效果不明显,但其产量显著高于当地习惯施肥处理。表明施用硫肥可在一定程度上提高玉米的产量,并可观地提高了经济效益。

Analysis on Maize Sulfur-based Compound Fertilizer Experimental Results in Xinzhou City

Sulfur is absolutely necessary for crop growth and development.Reasonable sulphur fertilizer application is more and more emphasized.Systematic plot experiments and larger area demonstration and extension of maize are taken in Xinfu,Yuanping and Dingxiang experiment and demonstration sites for sulfur-based compound fertilizer.The result shows that the maize yield with sulphur fertilizer application is not too much higher than that with the best formulation of local formula fertilization by soil testing,but it is much higher than that with local conventional fertilization;The result of sulphur fertilizer application in some experimental units is much higher than that with best formulation of local formula fertilization by soil testing and is much higher than that with local conventional fertilization.The result of demonstration experiment shows that sulphur fertilizer application has stimulation effect to some extent for maize and it improves economic benefit considerablly.
