鸭梨无公害生产环境及栽培量化指标与调控技术研究

通过多年来的系统研究,明确了鸭梨无公害生产的环境质量指标,制定了鸭梨无公害栽培果实品质性状、树体结构、产量水平及效益指标,以及果实重金属和农药残留限量指标,集成配套了相适应的栽培调控技术,包括水分调控、配方施肥、平衡修剪、疏花疏果、人工授粉、梨果套袋、病虫防治及适期采收等8项关键技术,为鸭梨实现无公害高品质栽培,提高国内外市场竞争力,增加经济效益和出口创汇提供了科学依据。

Pears Pollution-free Production Environment and Cultivation Quantitative Indicators and Control Technology

Through years of system research,pears pollution-free production environment quality indicators were determined,pears pollution-free cultivation fruit quality traits,tree structure,production level and efficiency indicators were formulated,as well as fruit heavy metals and pesticide residue limits index.The corresponding cultivation control technology was integrated,including water regulation,fertilizer,balance pruning,hydrophobic flower thinning,artificial pollination,pome sack,disease and insect control and optimum period of recovery,which will provide scientific basis for realizing pears pollution-free high quality cultivation,improving market competitiveness at home and abroad,increasing the economic benefit and provide a scientific basis for export.
