为华北平原冬小麦高产简化栽培提供理论依据,以黄淮海区域推广面积最大的冬小麦品种百农矮抗58为材料,在大田条件下,研究了秸秆还田对其根际土壤微生物数量及产量的影响。结果表明,随着生育进程的推进,根际土壤微生物数量呈先升高后降低的趋势,其中在开花期较高。根际土壤微生物数量和产量表现为玉米秸秆还田翻耕>玉米秸秆还田旋耕>玉米秸秆清除旋耕。建议,要进一步推广秸秆还田并结合深耕,增加产量,促进农业的可持续发展。
This study provided a theoretical basis for high-yielding simplified cultivation of winter wheat in the North China Plain. Based on field experiments, the effects of straw incorporation on rhizospheric soil microbial population and yield were studied in the Huang-Huai-Hai region, the largest wheat variety, . The results showed that along with the progress of fertility, the number of rhizosphere soil microbial biomass increased first and then decreased, especially in flowering stage. The amount of rhizosphere soil microbial biomass and yield were as follows: corn stalks returning to field tillage> corn stalks returning to field tillage> corn stalks clearing tilling. Suggestions, we should further promote the return of straw and deep plowing to increase production and promote the sustainable development of agriculture.
