该文通过对邓州市2006~2007连续两年所分析的4 700个土样有效硫(S)化验结果整理分析发现,邓州市目前近30%耕地中有效态硫含量对禾谷类作物而言是缺乏的,有近60%的耕地中有效态硫含量对于种植十字花科、百合科、豆科等需硫较多的作物来说,属于潜在缺硫耕地;同时从施肥结构、种植结构变化详细分析了其产生的原因,并依据硫在植物体内移动状况、硫肥性状等因素提出相应对策。 Through the analysis of the available sulfur (S) test results of 4 700 soil samples analyzed by Dengzhou City for two consecutive years from 2006 to 2007, it is found that the available sulfur content in nearly 30% About 60% of the available sulfur content in cultivated land is potentially deficit for the cultivation of crops that require more sulfur, such as crucifer, liliaceae and legumes. At the same time, from the aspects of fertilization structure, planting structure Changes in detail analyzed the reasons for its occurrence, and based on the movement of sulfur in plants in vivo, sulfur fertilizer and other factors put forward corresponding countermeasures.
