What should I do if crops in Northeast China encounter low temperature in summer?

The chilling injury in summer refers to the long-term cold and humid weather in Northeast China in summer, which leads to insufficient heat conditions and increased accumulated temperature during crop growth, resulting in a large-scale crop yield reduction disaster. The chilling injury in summer in Northeast China is a large-scale disastrous weather, which is really difficult to defend, but it can be alleviated by strengthening field management. Water can be used to regulate the temperature of rice fields. Before the arrival of low temperature, measures should be taken to water deep water to keep warm and protect seedlings. When the temperature rises, it is necessary to drain water in time to raise the soil temperature. Corn, soybean and other crops should take timely intertillage weeding and other measures to improve the ground temperature and promote the robust growth of crops.
