| 摘 要： | 通过盆钵模拟试验得出:①随着稿杆用量的增加,稿杆对土壤氮素固定加大;②土壤种类不同,在相同情况,稿杆对土壤氮素固定不同;③在一定温度条件下,培养时间越长,稿杆对氮素固定逐渐减少。

| Abstract: | Based on the pot culture, the results of the study are as follows: (1) that the more the content of straw is used, the more content of nitrogen fixation in soil is. (2) that different soil types give rise to the different contents of nitrogen fixation in soils on the condition of same treats. (3) that the determined temperature, the longer the culture time is, the smaller the content of nitrogen fixation in is soil is. |
