项目摘要
Approx. 1/3 of all vegetables consumed in China are produced mostly by smallholders in so called solar greenhouses. However, farmers are overusing fertilizers, specifically N based fertilizers, and application rates >2000 kg N hectare and year in two growing seasons are rather normal and not the exception. This has caused and is causing tremendous environmental problems: soil acidification and salinization, degradation of soil ecological functions and increase occurrence of pathogens, accumulation of fungicides, pesticides and nitrates in top- and subsoils, nitrate pollution of groundwater, and increased losses of the greenhouse gas N2O. The overall objective of the project is the characterization and quantification of changes in plant and/ or microbial N removal, N immobilization processes and gaseous N losses for differently managed greenhouse soils as compared to conventionally managed arable soil. Thus, the project aims at the identification of feasible approaches for soil restoration and mitigation of soil hydrological and gaseous N losses from soils of intensively managed greenhouse vegetable production systems. Based on the overall objectives the following sub-objectives have been defined: 1) Quantification of the temporal dynamics of topsoil (0 to 1 m) and subsoil (1 to 3 m soil depth) changes in C and N stocks of solar greenhouse soils using a chronosequence approach. 2) Quantification of changes in actual and potential denitrification rates in soil profiles of intensively managed solar greenhouse vegetable system as affected by management and land use history. 3) Assessment of the effectiveness of anaerobic soil infestation and DOC additions to subsoils for removing excess NO3- from top- and subsoils. Thereby, tracing the fate of subsoil produced N2O for its possible contribution to soil-atmosphere N2O fluxes. 4) Identification of the potential of different solar greenhouse soil restoration measures and management methods such as biochar and/or straw application as well as drip irrigation for its effectiveness in increasing soil health, soil N retention potentials and NUE efficiency as well as reducing greenhouse gas emission and hydrological N losses from greenhouse vegetable production systems.
约中国消费的1/3的蔬菜主要是由所谓的日光温室的小农生产的。然而,农民过度使用化肥,特别是氮肥,在两个生长季节的施用量>2000 kg N公顷和年是相当正常的,而不是例外。这已经造成并正在造成巨大的环境问题:土壤酸化和盐碱化,土壤生态功能退化,病原体增加,杀真菌剂、农药和硝酸盐在表土和底土中积累,地下水硝酸盐污染,以及温室气体N2 O损失增加。该项目的总体目标是表征和量化不同管理的温室土壤与常规管理的耕地土壤相比,植物和/或微生物氮去除、氮固定过程和气态氮损失的变化。因此,该项目的目的是确定土壤恢复和减轻土壤水文和气体氮从集中管理的温室蔬菜生产系统的土壤损失的可行方法。基于总体目标,确定了以下子目标:1)采用时序方法量化日光温室土壤C和N储量的表土(0至1 m)和底土(1至3 m土壤深度)变化的时间动态。2)受管理和土地利用历史影响的集约化管理日光温室蔬菜系统土壤剖面中实际和潜在反硝化速率变化的量化。3)评估厌氧土壤侵染和DOC添加到底土中以从顶部和底土中去除过量NO3-的有效性。因此,追踪底土产生的N2 O的命运,以确定其对土壤-大气N2 O通量的可能贡献。4)确定不同日光温室土壤恢复措施和管理方法的潜力,如生物炭和/或秸秆施用以及滴灌,以提高土壤健康,土壤氮保持潜力和NUE效率,以及减少温室气体排放和温室蔬菜生产系统的水文氮损失。
