| 摘 要： | 本文主要阐述覆膜栽培耕层土壤主要酶与有效养分变化及其相关性。试验结果表明:无论在供试作物、苗木生长初期或最大营养期,耕层土壤转化酶、中性磷酸酶、速效氮、速效磷均有显著提高。从相关性测定亦表明:覆膜处理耕层主要土壤酶与有效养分之间相关性高于未覆膜处理。

| Abstract: | This paper mainly states the coherency between the main enzymes and the available nutrient in ploughed layer in soils mulched with film. The test shows that in the filmcovered field, all of the soil invertase, neutral phosphatase, rapid available P and rapid available N in ploughed layer have an ovious increase during whatever the maximum-nut rit in growth period or the seedling growth period. The coherency test also results that the coherency between soil enzymes and available nutrient in the film-covered film is higher than that in the no-film-covered field. |
