No-tillage and subsoiling increased maize yields and soil water storage under varied rainfall distribution: A 9-year site-specific study in a semi-arid environment
Field Crops Research(2020)
摘要
•The efficiency of tillage methods under different rainfall distribution on spring-maize production was investigated.•Subsoiling demonstrated significant enhancement on soil water storage in normal years, while no-tillage in dry/wet years.•Subsoiling decreased soil reservoir scarcity in dry/ normal, no-tillage increased reservoir supplementation in wet years.•Both no-tillage and subsoiling increased soil water consumption at reproductive growth stages, improved yield out and WUE..
