为了探讨机械作业改良白浆土,以常规机械作业为对照,设6个处理,研究心土不同间隔混拌对白浆土物理性质及大豆产量的影响。结果表明:与对照相比,改土2年后不同处理20～60cm混拌层都能提高土壤含水量,增幅1.02%～4.90%;降低土壤容重,降幅4.93%～10.56%;降低土壤硬度,降幅3.05%～28.15%;以单向条沟改良(T2)效果最好。6个处理中,隔垄交错条沟改良(T5)和单向条沟改良(T2)大豆产量最好,分别达到1991.92kg/hm2和1969.57kg/hm2,比常规机械作业提高7.92%和6.71%,差异达到显著水平。
In order to discuss the mechanical work to improve Albic soil, 6 mechanical treatments were used as the control to study the effect of different mixing intervals on physical properties and soybean yield of Albic soil. The results showed that compared with the control, the soil moisture content increased by 1.02% ~ 4.90% and the soil bulk density decreased by 4.93% ~ 10.56% after 20 ~ 60cm mixed layer treatment for 2 years. Soil hardness was decreased, A decrease of 3.05% ~ 28.15%; one-way ditch improvement (T2) the best. Among the six treatments, the yield of soybean (T5) and unilateral ditch improvement (T2) was the best, reaching 1991.92kg / hm2 and 1969.57kg / hm2, respectively, which increased by 7.92% and 6.71% , The difference reached a significant level.
