首次研究银杏根际土壤酶的活性及其与土壤农化特性、银杏产量的关系．结果表明，中、低产银杏根际土壤中酶活性显著低于高产的土壤．揭示银杏根际土壤酶活性的水平与垂直分布规律，为确定银杏施肥的最佳水平位置及深度提供了新的理论依据． The first study of ginkgo rhizosphere soil enzyme activity and its relationship with soil agronomy, ginkgo production. The results showed that the enzyme activities of rhizosphere soil of medium and low yield ginkgo were significantly lower than those of high yield soil. Reveal the horizontal and vertical distribution of soil enzyme activities in the rhizosphere of Ginkgo biloba, providing a new theoretical basis for determining the optimal level and depth of fertilization.
