Effects of planting Asparagus cochinchinensis in different artificial forests on soil physical properties and nutrient content
摘要
Abstract
In order to explore the effect of planting Asparagus cochinchinensis in different artificial forests,soil physical properties and nutrient contents between different layers of soil were studied by interplanting 1-year-old A.cochinchinensis seedlings in pure Cun-ninghamia lanceolata forest,C.lanceolata+Pinus massoniana mixed-forest,C.lanceolata+Eucalyptus mixed-forest and pure Schi-ma superba forest.The results showed that most of the physical indexes were significantly different among different planting models(P<0.01).The soil water holding capacity of S.superba-A.cochinchinensis was better than that of C.lanceolata-A.cochinchinensis among pure forest models,and the soil water holding capacity C.lanceolate+P.massoniana/Eucalyptus-A.cochinchinensis model was im-proved compared with that of C.lanceolata-A.cochinchinensis model.Only total nitrogen and total potassium contents of forest soil were significantly different in the 0~20 cm soil layer(P<0.01),but all the indexes were significantly different in the 20~40 cm soil lay-er(P<0.01).The soil nutrient content of S.superba-A.cochinchinensis model was higher than that of the C.lanceolata-A.cochinchinen-sis model,while the soil nutrient content of C.lanceolate+P.massoniana/Eucalyptus-A.cochinchinensis in the 0~20 cm soil layer was better than that of the C.lanceolate-A.cochinchinensis model,but the nutrient accumulation in the 20~40 cm soil layer varied accord-ing to the model.For the rhizosphere soil of A.cochinchinensis,only the total carbon content was extremely significantly different among models(P<0.01).The nutrient content of the rhizosphere soil in S.superba-A.cochinchinensis was the best,and the nutrient content of the rhizosphere soil in mixed forest of C.lanceolata was higher than that of pure forest of C.lanceolata.In conclusion,soil properties were improved under the S.superba-A.cochinchinensis model,which could be extended in production.However,the supple-mentation of nitrogen and potassium fertilizer should be emphasized.The soil properties of C.lanceolate+P.massoniana/Eucalyptus-A.cochinchinensis model were better than those of C.lanceolata-A.cochinchinensis model.关键词
