摘要
试验结果表明,复播大豆各施肥处理较对照明显增产,差异达极显著水平;每公顷追施尿素75kg、普钙187.5kg,单产最高;在施肥总量一定时,苗期和分枝期或始花期两次追施较苗期一次追施效果好。
The test shows that: After dressing,the soybean yields are increased noticeably;Dressing urea 75kg and calcium fertilizer 187.5kg per hectare,the yield per unit is highest.When it is certain of the total fertilizing amount,the effect of dressing two times respectively at seedling stage and early flowering stage is better than only dressing at seedling stage.
