摘要
以粮油作物为对象,以多年的肥料田间试验和区域耕地地力调查数据为信息源,根据测土配方施肥原理,开发形成了浙江省桐庐县粮油作物智能信息化测土配方施肥技术管理系统,并在生产中进行了应用。该管理系统达到了"智能化、信息化、精确化和全覆盖"的施肥目标,实现了一个系统、一幅图、一套表、一张卡和一次购肥的"五个一"测土配方施肥技术推广工作模式。应用试验结果表明,采用智能信息化测土配方施肥技术指导施肥,油菜产量和经济效益均明显高于常规施肥。
Taking grain and oil crops as management object, using data obtained from long-term fertilizer field experiment and fertility survey of regional soils as a source of information, an information management system of intelligent-informatization soil testing and fertilizer recommendation of Tonglu County in Zhejiang Province was developed according to principle of the formula fertilization by soil testing. The management system had been applied in production of grain and oil crops. Application of the management system had achieved a target of fertilization with the characteristics of intelligent,informatization, accurate and full coverage, and realized extension mode of technology for formula fertilization by soil testing which included five-factor-combination of a system, a picture, a table, a card and one purchase of fertilizers. The application results showed that yield and economic benefit of rape based on information management system of intelligent-informatization soil testing and fertilizer recommendation were significantly higher than the conventional fertilization.
