Abstract

Abstract:

Saline-alkali land is an important reserve arable land resource in the country. Selecting and breeding salt-tolerant rice varieties in cold regions, and developing and utilizing saline-alkali land are important ways to promote food production and ensure national food security. In accordance with the national guiding spirit of "transforming from controlling saline-alkali land adaptation crops to selecting saline-alkali-tolerant plants to adapt to saline-alkali land, tapping the potential for saline-alkali land development and utilization, and striving to achieve breakthroughs in key core technologies and important innovation fields", a series of issues such as the imperfect technical system for saline-alkali land improvement have been addressed through collaborative research using new generation information technologies such as the Internet of Things and big data. A monitoring platform for saline-alkali land in cold regions has been built that integrates dynamic monitoring of the meteorological and soil environment of saline-alkali land, collection of phenotypic data of rice in cold regions, and visual display of data, achieving the integration of information technology in multiple disciplines such as germplasm resources, biotechnology, and soil fertilizers. This article introduces the digital monitoring methods and key technologies of data collection content for the improvement and utilization of saline-alkali land in cold regions from the perspective of platform architecture and functional implementation. The platform has been applied in different accumulated temperature zones such as Daqing, Jiamusi, and Heihe in Heilongjiang Province. The results show that the platform can assist scientific researchers to timely and comprehensively grasp the meteorological and soil information of saline-alkali plots, effectively reduce the impact of adverse environmental factors, and form a complete data chain; The platform aggregates and processes phenotypic traits, yield and quality data of rice germplasm resources at different phenological stages, excavates the environmental stress response rules of germplasm resources, and guides the scientific research and production of rice in saline-alkali lands, providing information technology support for the development and utilization of saline-alkali land resources. And realizing digital monitoring of saline-alkali-tolerant rice screening and soil improvement in cold regions.

Key words: saline-alkali land, rice in cold zone, Internet of Things
