摘要

摘要本研究对两个种植年份的保护性耕作（CST）和常规耕作（CT）下的水足迹（WF）、小麦水分生产力（WWP）以及水足迹组成之间的相互关系进行了评估。结果显示CST组WF明显低于CT组。而CST中的WWP高于CT。保护性耕作（与传统耕作相比）中的总WF、绿色、蓝色和灰色WF平均为1319（与1629）、108（与152）、621（与737）和590（与740）m3 t-1。灰色WF对总WF的直接影响最大，产量也较高（3857 kg ha−1），秸秆产量（5065 kg ha−1）和WWP（1.01 kg m−3）。研究结果表明，与CT相比，CST是减少总WF（19%）、提高作物产量和小麦生产生产力的合适耕作方法。

Water footprint in wheat production under conservation tillage

ABSTRACT Water footprint (WF), water productivity of wheat (WWP) and interrelationships among water footprint components under conservation (CST) and conventional (CT) tillage were evaluated for two cropping years in this study. Results revealed that WF in CST was lower than that in CT one. While, WWP in CST was higher than that acquired from CT. The total, green, blue and gray WF in conservation (vs. conventional) tillage averaged 1319 (vs. 1629), 108 (vs. 152), 621 (vs. 737) and 590 (vs. 740) m3 t−1. The gray WF had the highest total and direct effects on total WF. Also, higher grain yield (3857 kg ha−1), straw yield (5065 kg ha−1) and WWP (1.01 kg m−3) acquired from CST. The findings revealed that CST is the appropriate tillage practice to reduce total WF (19%) compared to CT, to enhance crop yield and productivity in wheat production.

期刊介绍： rchives of Agronomy and Soil Science is a well-established journal that has been in publication for over fifty years. The Journal publishes papers over the entire range of agronomy and soil science. Manuscripts involved in developing and testing hypotheses to understand casual relationships in the following areas: plant nutrition fertilizers manure soil tillage soil biotechnology and ecophysiology amelioration irrigation and drainage plant production on arable and grass land agroclimatology landscape formation and environmental management in rural regions management of natural and created wetland ecosystems bio-geochemical processes soil-plant-microbe interactions and rhizosphere processes soil morphology, classification, monitoring, heterogeneity and scales reuse of waste waters and biosolids of agri-industrial origin in soil are especially encouraged. As well as original contributions, the Journal also publishes current reviews.
