摘要
以"犍为黄口姜"为试材,通过大田栽培试验,研究了不同栽培模式(生姜单作,生姜与大豆间作,生姜与四季葱间作,生姜与大蒜间作,生姜与大豆、四季葱混作,生姜与大豆、大蒜混作,生姜与四季葱、大蒜混作和生姜与大豆、四季葱、大蒜混作)对生姜大田旺盛生长期和收获期土壤酶活性及土壤养分的影响。结果表明:与生姜单作相比,所有间作系统均在旺盛生长期和收获期不同程度地提高了土壤酶活性;在环境条件相同的情况下,间作模式下生姜的根际土壤养分有效性均高于生姜单作(如有效磷、速效钾和铵态氮),同时间作较单作减少了土壤中硝态氮的积累;并且部分土壤酶活性与土壤养分之间呈正相关性,如土壤蛋白酶、蔗糖酶活性与土壤有效磷含量呈正相关,反硝化酶活性与土壤有机质、土壤速效钾含量呈正相关,土壤酸性磷酸酶、纤维素酶及多酚氧化酶活性与土壤速效钾含量呈正相关。
Taking ＇Qianwei Huangkou ginger＇ as test material, the effect of different cultivation patterns （such as ginger monocutture,ginger and soybean intercropping, ginger and green onion intercropping, ginger and garlic intercropping, ginger, soybean and green onion mixed-cropping, ginger, soybean and garlic mixed-cropping, ginger, green onion and garlic mixed-cropping,ginger, soybean,green onion and garlic mixed-cropping） on soil enzyme activities and soil nutriems at the vigorous growth stage and harvest stage of ginger field were studied in this article by field experiment. The results showed that all intercropping systems increased soil enzyme activities to different extent both at vigorous growth stage and at harvested stage compared to solo ginger. In the same environment conditions, the effectiveness of ginger rhizosphere soil nutrients in intercropping mode were higher than that of solo ginger such as available phosphorus, available potassium and ammonium nitrogen. And the nitrate accumulation in intercropping mode was reduced compared with solo ginger. Furthermore,there was a positive correlation between partial soil enzyme activities and soil nutrients. Such as soil protease, invertase activity was positively correlated with soil available phosphorus content, denitrifying enzyme activity was positively correlated with soil organic matter and soil available potassium content, and soil acid phosphatase,cellulose and polyphenol oxidase activity was positively con＇etated with soil available potassium content.
