摘  要:
It was beneficial to decreasing soil bulky gravity and increasing non-capillary porosity and gas/liquid ratio with cultivation year after year. Meanwhile, the soil chemical properties were also improved. The contents of organic matter, hydrolytic N, available P and exchangeable K were all increased and soil pH value was ameliorated. As a result, the crops grew well with high-yield capacity.
