    The study was supported by the Special Fund for Agro-scientific Research in the Public Interest (201503116) and the National Key Research and Development Program of China (2016YFD0300103, 2016YFD0300801).

Abstract:

Field experiments were conducted in 2015 and 2016 at Tieling city, Liaoning province of Northeast China to study the effects of straw stripe returning on yield of spring maize, and the relationships of yield with soil moisture, nitrogen and maize root spatial distribution. The experiments included four treatments: (1) the ridges of the rotary tillage with straw returning (RR+S); (2) the ridges of rotary tillage without straw returning (RR); (3) interlaced ridges of rotary tillage with straw returning (IR+S); (4) interlaced ridges of rotary tillage without straw returning (IR). Compared with no straw returning, under RR+S and IR+S treatments the yield, increased by 6.7% and 8.2%, respectively, with more significant yield-increasing effect in dry year (2015) than in rainy year (2016); their grain number per spike and harvest index increased significantly, but there was no significant difference in 1000-grain weight; their soil moisture content increased by 7.8% and 6.1%, and their soil nitrogen increased by 6.9% and 4.5%, respectively; their root length significantly increased by 29.4% and 22.7%, and the water use efficiency was increased by 7.8% and 7.0%, respectively. We conclude that the straw strip returning (RR+S and IR+S) can improve water use efficiency and grain yield by optimizing distribution of soil structure, moisture and nitrogen. This study provides useful references for improving spring maize yield and straw comprehensive utilization in Northeast of China.

Key words: straw strip returning, yield, root distribution, soil moisture content, nitrogen distribution, water use efficiency
