淹水条件下,土壤氮素的矿化是土壤有效积温的函数。用淹水密闭培养法,预测田间种稻下土壤氮素的矿化量和矿化过程时,其准确性受到许多因素的影响。为了明确水稻生长对土壤氮素矿化的影响程度,以及不同季别的水稻在这方面的异同,我们进行了下述试验。 Under flooding conditions, mineralization of soil nitrogen is a function of soil available accumulated temperature. With the submerged airtight culture method, the accuracy of soil N mineralization and mineralization under field rice cultivation is affected by many factors. In order to clarify the impact of rice growth on soil nitrogen mineralization, and the similarities and differences between rice in different seasons, we conducted the following experiments.
