摘要

在浙东滨海平原选择连作时间为3～4年

8～10年和20年以上的大棚蔬菜地及蔬菜-水稻轮作8～10年和20年以上的大棚蔬菜地

同时选择刚围垦和经围垦改良脱盐的其他农地作为对照

分析研究不同种植年限和种植模式蔬菜地土壤微生物区系和酶活性

探讨长期种植蔬菜对涂地土壤生物学性质的影响。结果表明

围垦涂地种植蔬菜3～4年内

土壤有机质、氮和磷的全量和有效态、土壤微生物生物量碳、微生物数量、土壤酶活性均呈现增加的趋势

土壤质量明显改善;连作蔬菜8～10年后

土壤速效养分继续呈增加趋势

但土壤盐分显著积累

同时土壤生物学性质明显恶化(细菌和放线菌数量减少、真菌数量增加、土壤酶活性降低、土壤微生物生物量碳降低)。与连作相比

轮作可显著地防止土壤生物学性质的恶化。磷脂脂肪酸(PLFA)的方法研究也表明

蔬菜种植时间、种植方式(连作、轮作)对土壤生物学性质有很大的影响。

Abstract

Vegetable lands in polytunnel greenhouse from coastal plain of eastern Zhejiang province with continuous cropping of 3-4 years

8-10 years

and more than 20 years

and rice-vegetable rotation cropping of 8-10 years and more than 20 years were selected for studying differences in soil microbial community and enzyme activities in vegetable lands with varying cultivation years and planting systems.Both newly-enclosed coastal land and reclaimed coastal land without vegetable cropping were also selected for compari...
