氮素与抑制剂双控释尿素的制备及其对土壤供氮能力和小麦产量的影响

Preparation of Nitrogen and Inhibitor Controlled-release Urea and its Effects on Soil Nitrogen Supply Capacity and Wheat Yield

对于植物生长发育而言,氮是极为重要的。不过,在土壤之中,所能够产生的氮元素相对较少,无法满足植物的生长需求,供给与需求之间存在着较为严重的不平衡性,以至于植物的生长很难得到有效保障。随着我国社会科学技术水平的不断提升,人们将氮肥作为主要的应用物质,以此来确保粮食安全能够得到保障。但是,在这一过程中,有关氮肥的利用率却很难得到提升,经常会出现浪费的情况,对农业的发展产生较为不利的影响。因此,本文就氮素与抑制剂双控释尿素的制备及其对土壤供氮能力和小麦产量的影响进行相应的论述与分析。

Nitrogen is very important for plant growth and development.However,in the soil,the nitrogen element that can be produced is relatively small,which can not meet the growth demand of plants.There is a serious imbalance between supply and demand,so that the growth of plants is difficult to be effectively guaranteed.With the continuous improvement of China's social science and technology level,people take nitrogen fertilizer as the main application material to ensure food security.However,in this process,the utilization rate of nitrogen fertilizer is difficult to be improved,and waste often occurs,which has a more adverse impact on the development of agriculture.Therefore,the preparation of nitrogen and inhibitor dual controlled-release urea and its effects on soil nitrogen supply capacity and wheat yield were discussed and analyzed in this paper.
