硫肥对油菜生长的影响研究进展

Progress for Effect of Sulfur on Rapeseed Growth

油菜是一种主要油料作物。目前土壤缺硫和潜在缺硫已经成为影响油菜生长及产量提高的限制因素,而产量潜力高的杂交油菜生长需要较多的硫肥,因此有效地施用硫肥在提高油菜产量方面有重要作用。不同形式硫肥在土壤中通过土壤微生物介导在相关酶作用下转化为硫酸根离子,硫素被油菜根系吸收的主要形态是土壤溶液中硫酸根离子形式。油菜的生长和产量与硫肥的施用量、土壤环境、施用时间及方式等因素相关。

Rapeseed is one of major oilseed crops. Currently sulfur deficiencies of soil have became an restrictive factor influencing the growth and yield increase of rapeseed, but the rapeseed with high yield potential would demand more sulfur fertilizer, so to effectively apply sulfur fertilizer would be important to the increase of rapeseed yield. The different types of sulfur fertilizer in soil would be mediated and transformed into sulfate ions through concerned enzymes hydrolysis, and main forms of sulfur would be changed into sulfate ions in soil solution after being absorbed by rapeseed roots. Growth and yield of rapeseed are depending on the soil environment, rate, timing and methods of application and so on.
