油菜硫肥效应研究

试验结果表明 :施硫肥能促进油菜植株的生长发育和增加菜籽产量。各施硫处理与对照相比 ,株高、单株结果数、每角果粒数及单株生物学产量均有不同程度的提高。对照菜籽产量为 2 6 76 .2 kg/hm2 ,施硫处理产量增加 15 7.43～ 314.85 kg/hm2 ,增幅为 5 .83%～ 11.76 % ,产量差异达到了极显著水平。施硫处理产投比为 2 .31～ 6 .30。处理 3(施 S95 45 kg/hm2 )效果最好

Study on the Response of Rape to Sulfate-fertilizer Application

Experimental results indicated that applying Sulfate fertilizer could promote the rape growth and increase rapeseed yield.Plant height,shell number per plant,kernel number per pod and biological yield per plant increased at different degree.Yield of CK was 2676.2 kg/hm 2 ,yield of crops treated increased by 157.4～314.9kg/hm 2(5.83～11.76% over the control).The yield differences between the control and treatments were significant.The ratio of output and input was 2.31～6.30 And it showed that treatment 3(Sulfate fertilizer,45kg/hm 2)had the highest effect on the increase of rapeseed yield.
