一、概述 作物规范化栽培技术,是世界上发达国家发展农业生产的重要措施。它所要解决的问题是,如何把各项农艺措施(诸如播期、密度、灌水定额及时间、施肥时期和数量等)科学地组装起来,使作物的栽培标准化、规范化,实现作物栽培的高产低成本。 显然,要科学地组装各项农艺措施(因子),形成优化栽培技术方案,则必须研究诸 I. Overview Crop standardization cultivation techniques are the important measures for the development of agricultural production in developed countries in the world. The problem to be solved is how to scientifically assemble various agronomic measures (such as sowing date, density, irrigation quota and time, fertilization period and quantity, etc.) to standardize and standardize crop cultivation and achieve high yield of crop cultivation cost. Obviously, to scientifically assemble agronomic measures (factors) and form optimized cultivation techniques, it is necessary to study
