When does spring ploughing start every year?

Affected by climatic factors, the spring ploughing time varies from place to place. The spring ploughing time in the south was earlier, and it was postponed to the north in turn. The farther north, the later the spring ploughing season. Generally speaking, the temperature in the south rises rapidly. Spring ploughing begins in late February and early rice is sown in March every year. Spring ploughing time in North China is generally from early March to April. Spring ploughing in Northeast China is usually at the end of April. In terms of solar terms, most parts of the country are surprised by the busy season of spring ploughing. —— The above content is taken from Millay's children's book Field Natural History Class.
