| 摘 要： | 以大豆（沧豆6号）为绿肥材料,在田间采用埋入和覆盖尼龙袋子的方法,研究了不同栽培条件（是否种植玉米）、利用方式（埋入土壤、覆盖在地表）和使用量（200 g/袋、250 g/袋）下绿肥腐解速率的变化。结果表明：大豆绿肥的腐解过程表现为前期腐解快、后期腐解逐渐减慢的特点,在种植玉米条件下比不种植玉米条件下腐解得快,在施用化肥条件下比不施化肥条件下腐解得快,绿肥埋深10 cm比覆盖在地表腐解得快,但差异均不显著;在田间翻埋条件下,大豆绿肥的腐解速率几乎不受翻压量的影响。

| Abstract: | The effects of cultivation conditions of soybean,use patterns and application amount of green manure on the decomposition rate were studied.The results showed that the green manure decomposed rapidly in the earlier stage,and decomposed slowly in the later stage.It decomposed fast with maize planting.It decomposed fast by applying chemical fertilizer.When the green manure was buried under 10 cm soil layer,it decomposed faster.The application amount had no influence on the decomposition rate. |
