In order to understand the overall production status of international seedling production affected by high temperature and drought, and the impact on the industrial chain or market, the import situation of seeds of 18 crop categories from 2011 to 2021 was collected. In terms of import value and import volume, the strategic target countries are limited to Mainland China, Thailand, the United States and Australia (Figures 1 and 2). At the same time, further collecting opinions of domestic seedling companies on impact of high temperature and drought (Figure 3). Take inventory and integration of industrial strategies to cope with drought and high temperature as a consideration for our country's industrial layout.
