深松耕作对作物产量和水分利用率影响的Meta分析
Meta-analysis of the Effects of Subsoiling Till-age on Crop Yield and Water Use Efficiency
摘要
Abstract
[Objective]The problems of soil compaction and low water use efficiency caused by conventional plowing and rotary tillage are becoming increasingly severe.Subsoiling tillage serves as a crucial agricultural measure for conserving farmland,enhancing crop yield,and improv-ing water use efficiency.However,in previous studies,the effects of subsoiling tillage on crop yield increase and water use efficiency improvement varied under different experimental factors.This paper aimed to explore the impact of subsoiling tillage on yield of different crops and soil water use efficiency(WUE),providing a theoretical basis for promotion and application of this tillage method.[Method]Two types of crops,wheat and maize,which grown in China were selected as research objects,relevant literature published by researchers was searched,and 266 sets of data from 56 eligible articles were screened.The effects of subsoiling tillage on yield and water use effi-ciency of the two crops were explored through meta-analysis.[Result]Under subsoiling tillage,both crop yield and water use efficiency were significantly improved,especially for wheat,the yield was increased by 11.7%compared to conventional tillage,and water use efficiency was in-creased by 11.9%compared to conventional tillage.However,continuous subsoiling tillage did not achieve a sustained yield increase effect.In arid and semi-arid regions(rainfall≤400 mm),subsoil-ing tillage had a significant effect on increasing crop yield,the crop productivity was increased by 10%.In the regions with more rainfall,subsoiling could better improve the utilization of natural pre-cipitation.[Conclusion]Subsoiling tillage can enhance crop productivity and water use efficiency,and the effect on wheat is better than on maize;a better effect on crop yield increase can be achieved in arid and semi-arid regions.关键词
