Abstract:
In order to find the effect of long-term wheat straw returning combined with chemical fertilizer on soil fertility and soybean yield，we carried out field trail in the dark brown soils of Heihe city in Heilongjiang province, and set six treatments.including control(CK)，wheat straw(S)，low levels of fertilizer(N1P1)，wheat straw + low levels of fertilizer(S+N1P1)，high levels of fertilizer(N2P2) and wheat straw + high levels of fertilizer(S+N2P2).The results showed thatsoil organic matter and pH were decreased with the increase of planting years，and the decrease range were slowdown under the condition of combined application of straw and chemical fertilizer;the fluctuations of the content of soil available N were obvious with the trend of decrease-increase-decrease during the whole experiment，the low valley appeared in 1984，1987 and 1990, respectively,the peak in 1993，and the content of the inter-annual average of soil available N showed as S+N2P2> N2P2> CK> S> N1P1> S+N1P1；the content of soil available P increased with the increasing of planting years，and the whole trend the inter-annual manifested as S+N2P2＞N2P2＞S+N1P1＞N1P1＞S＞CK；soybean yield varied with planting year，the inter-annual yield presented as S+N2P2> N2P2> S+N1P1> S > N1P1> CK.Results suggest wheat straw returning combined with proper chemical fertilizer could maintein soil fertility and improve soybean yield in the dark brown soils area.
