Abstract:

In the context of global climate change, the rice planting zoning in Keyouzhongqi Banner, Inner Mongolia was established. This article selected three highly correlated meteorological elements as zoning factors and developed climate zoning indicators for rice planting in Keyouzhongqi Banner. Based on ArcGIS geographic information system and digital elevation model, the observation data of accumulated temperature, frost free period, precipitation and other activities above 10℃ from the National Automatic Meteorological Observation Station and 42 regional automatic meteorological observation stations in Keyouzhongqi Banner from 1991 to 2020 were used. ArcGIS software was used to calculate spatial interpolation to obtain the spatial calculation conclusion of the zoning indicators. The rice planting meteorological area in Keyouzhongqi Banner was divided into three zones: suitable zone, sub suitable zone and unsuitable zone. Suitable areas should choose high-yielding, high-quality, and stress resistant mid to late maturing rice varieties with longer growth periods and high yield potential. The planting mode should adopt precision farming and large-scale planting to improve production efficiency; in the sub suitable areas, early maturing or mid maturing rice varieties with strong adaptability to drought, cold, and barrenness should be selected. The planting mode should adopt water-saving irrigation, intercropping, etc., and actively develop ecological agriculture; in unsuitable areas, rice varieties with strong stress tolerance or high resistance can be selected for improvement. In areas where rice cultivation is not suitable, measures such as converting paddy fields to dry fields can be taken to plant suitable crops. We should Strengthen land consolidation and soil improvement, gradually improve planting conditions, and develop other agricultural industries such as animal husbandry and forestry. The zoning results can provide an important basis for local optimization of rice layout, selection of suitable varieties and formulation of scientific planting strategies.
