| 摘 要： | 通过田间栽培试验,研究玉米/大豆间作及相应单作不同时期作物地上部干质量、作物吸氮量、作物根际土壤脲酶活性、作物根际土壤细菌数量动态变化差异。结果表明:间作玉米吸氮量、根际脲酶活性、根际细菌数量、地上部干质量分别比单作玉米显著增加37.61%,33.54%,55.76%,27.92%。间作大豆根际脲酶活性、根际细菌数量分别比单作大豆显著增加41.3%,43.08%。间作大豆吸氮量、地上部干质量比单作大豆降低11.93%,11.19%,差异不显著。说明间作促进玉米生长。

| Abstract: | Through field cultivation experiments on corn/soybean intercropping and the corresponding single crops for different periods of shoot dry weight,crop N uptake,the rhizosphere of urease activity of the soil,crop rhizosphere soil bacteria dynamic difference.The results showed:intercropping maize nitrogen uptake,rhizosphere urease activity,rhizosphere bacteria,shoot dry weight,respectively than corn significantly increase 37.61%,33.54%,55.76%,27.92%.Intercropping soybean rhizosphere urease activity, rhizosphere bacteria volume than soybean significant increase 41.3% and 43.08%.Intercropping soybean nitrogen uptake,shoot dry weight of soybean than lower 11.93%,11.19%,the difference was not significant.Note intercropping maize for growth. |
