一定生态条件决定了相应的种植制度,随着全球气候变暖,中国的气候变化与世界的气候变化相一致,气候变暖使干旱、冷害、少雨等不利气候因素更加频繁。在冬小麦生长期内由于气候变暖使冬小麦在常规条件下播种,容易造成苗期徒长,不仅浪费自然资源,还有可能使冬小麦越冬期遭遇严寒造成冷冻害,因此,冬玉米现在已经越来越多的应用。 Certain ecological conditions determine the corresponding planting system. With the global warming, China’s climate change is consistent with the world’s climate change. Climate warming makes adverse climatic factors such as drought, cold damage and less rainfall more frequent. Winter wheat growing season due to climate warming so that winter wheat sown under normal conditions, likely to cause leggy growth at the seedling stage, not only a waste of natural resources, winter winter wheat may also experience severe cold caused by freezing injury, so the winter corn has now more and more Many applications.
