秸秆还田方式与氮肥配伍对夏玉米产量及养分吸收的影响
Effects of straw returning mode and nitrogen fertilizer application compatibility on summer maize yield and nutrient absorption
摘要
Abstract
The effects of straw returning modes,different nitrogen(N)fertilizer types and rates on summer maize yield,nutrient accumulation and soil fertility in lime concretion black soil and cinnamon soil in North China Plain were investigated to provide valuable insights for optimizing straw returning practices,enhancing arable productivity and improving fertilizer reduction and efficiency.Field experiments were carried out in the summer maize season of 2023 in lime concretion black soil(Wuyang County,Henan Province),and cinnamon soil(Shijiazhuang City,Hebei Province).A three-factor interaction design was employed involving straw managements(no straw return,mulching return,shallow plowing return),N fertilizer types(urea,soybean meal,pig manure,yeast derivatives,glutamic acid)and N fertilizer rates(full rate,30%organic substitution rate,30%reduction in chemical fertilizer N plus 30%organic substitution rate).The yield and component factors,nutrient accumulation,nitrogen use efficiency,and soil physical and chemical properties were determined by the harvest of summer maize.The results showed that,summer maize yield in lime concretion black soil was notably influenced by the mode of straw return,N fertilizer types and rates.Returning straw through shallow plowing led to a significant increase in yield ranging from 4.45%to 15.35%compared with no straw return.The highest yield of 8 868.16 kg·hm-2 was achieved with glutamic acid substituting chemical fertilizer N under straw shallow plowing return,representing a 12.10%increase over full urea treatment.Additionally,the accumulation of N and potassium(K)in aboveground plant parts significantly increased by 22.39%and 16.14%,respectively.Moreover,N uptake efficiency,N fertilizer agronomic efficiency and N fertilizer partial factor productivity were also increased by 21.95%,77.25%,and 12.11%,respectively.Reducing N fertilizer generally decreased the yield by 2.22%-5.42%compared with full N application rates.Moreover,the type of N fertilizer and straw return modes also significantly increased summer maize yield in cinnamon soil.The highest yield,reaching 8 455.87 kg·hm-2,was achieved by replacing chemical fertilizer N with pig manure under straw mulching return,leading a significant 20.64%increase over full urea treatment.Accumulation of N,P,and K in aboveground plant parts were significantly increased compared with full urea treatment,with increments of 11.26%,17.97%,and 4.73%,respectively.Meanwhile,soil organic matter and total N showed increase of 13.81%and 8.85%,respectively.N fertilizer agronomic efficiency and N fertilizer partial factor productivity also increased by 11.48%and 6.65%,respectively.The combination of N fertilizer reduction with organic fertilizer application did not lead to a significant decrease in summer maize yield in cinnamon soil,and its long-term effect still needs to be explored in the future.In conclusion,straw shallow plowing return with glutamate substituting chemical fertilizer N 30%(total N 210 kg·hm-2),straw mulching return with pig manure substituting chemical fertilizer N 30%(total N 210 kg·hm-2)are feasible ways for straw efficient returning and summer maize yield improvement in lime concretion black soil and cinnamon soil,respectively.关键词
