应用卫星遥感技术对水稻长穗期长势监测的研究

The Research on Satellite Remote Sensing Technology for Monitoring the Growing of Booting Stage

本项研究通过卫星遥感技术,实现对水稻长穗期长势的遥感监测,并针对遥感信息开展调优措施,实现水稻稳产、高产的目的。通过试验研究,利用卫星遥感监测水稻长穗期后四叶长势,具备全面、准确的优势,准确度达80%,实现大范围监测,完成由"点"状数据向"面"的转变,并且依据遥感信息实施调优栽培技术,调整群体结构,这对于指导大规模水稻生产具有一定意义。

It can achieve monitor the growing of booting stage and high and stable yield by using satellite remote sensing technology. The results indicated that monitor the growing of later-4-1eaves by satellite remote sensing technology can achieve comprehensive and accurate data with 80% accuracy, it can realize monitoring on a large scale from a point to face and optimizing cultural technique, so it has some significance for guiding the mass production.
