Abstract:

The study discussed the distribution law of climate suitability of tomato in Ningxia, and aimed to provide reference for the regional planning of tomato cultivation. Based on the growth data of tomato provided by the Agricultural Technology Center of Huinong and the meteorological data provided by 24 meteorological observation stations, including the data of temperature, precipitation, and sunshine from 1981 to 2016, climate suitability models were established to analyze the variation characteristics of the suitability of meteorological factors. The results showed that the sunshine suitability was the most favorable meteorological factor for tomato growth in Ningxia, whose spatial distribution was high in the north and low in the south. The precipitation suitability decreased from south to north, but it could be compensated by the irrigation of the Yellow River, its high inter-annual variability made it the key factor affecting the inter-annual change of the climate suitability. The temperature suitability varied remarkably in different growth periods, and was the main meteorological factor that restricted tomato cultivation in Ningxia, and it gradually changed into a favorable condition. The suitability of the 4 cities in northern and central Ningxia was relatively high, and the meteorological condition in Guyuan was not conducive to the tomato growth and development. From the distribution of climate suitability, the climate suitability of tomato planting in the northern and central Ningxia is the best, and its overall climate condition is the most conducive to the growth of tomato.
