测土配方施肥技术是一种在国际上普遍采用的科学施肥技术。从化区是广州市的农业大区,测土配方施肥工作的开展对从化的农业生产起到了关键性的推动作用。科研人员通过对几种在从化广泛栽培的农作物进行测土配方施肥试验,积累了大量的“3414”田间试验数据,提出了从化区不同农作物最佳的氮磷钾配比、施用量和施用方法,为全国测土配方施肥指标体系的建立提供了科学依据和技术支持。
Soil testing and fertilizer technology is a formula commonly used in the international scientific fertilization technology. Conghua District is a large agricultural area in Guangzhou. The implementation of soil testing and formula fertilization has played a key role in promoting concretized agricultural production. Researchers have accumulated a large number of “3414” field trial data on several soil testing and fertilizer experiments conducted in Conghua widely cultivated crops and put forward the best N, P and K ratio and application rate of different crops in the Conghua area Application method for the national soil testing formula fertilizer index system provides a scientific basis and technical support.
