Abstract
To explore the effects of different animal manures on soil enriching and maize yield,effects of different kinds and amounts of animal manures on soil respiration rate,yield and water use efficiency were studied.The results showed that: the soil respiration rate in chicken manure and sheep manure treatments were higher(4.13 and 3.85 μmol/(m2·s)),while in pig manure and cattle manure were lower(3.73 and 3.46 μmol/(m2·s));the production with chicken manure and sheep manure increased by more than 35%,with pig manure and cattle manure increased by more than 25%,the production was the highest with the fertilizer of 20 230.0 kg/hm2(T3);water use efficiency increased as the fertilization increased,and the max was 31.07 kg/(hm2·mm) in chicken manure of T3.It was concluded that animal manures would increase maize yields,improve soil respiration rate and water use efficiency in an order from strong to weak as chicken manure pig manure sheep manure cattle manure.
