When is the long summer? A brief introduction to the long summer.

2. Long summer is the seventh solar term among the twenty-four solar terms, and it is also the first solar term in summer. Every year, the festival is held on May 05-07 in the Gregorian calendar. At this time, the bucket handle of the Big Dipper points to the southeast, and the longitude of the sun reaches 45. Long summer is an important solar term, marking the peak season for the growth of all things. Almanac: "The bucket refers to the southeast dimension and the long summer. Everything has grown up since then, so it is named Long Summer. " After the long summer, the sunshine increases, the temperature rises gradually, the thunderstorm increases, and the crops enter a vigorous growth stage.

Before and after the long summer, it is the season of transplanting early rice in the north and south of the Yangtze River. Full-moon seedlings can be planted, but full-moon grass can't be planted. At this time, the temperature is still low. Immediately after planting seedlings, we should strengthen management, topdressing early, ploughing early, controlling pests early and promoting development early. Pay close attention to tail sweeping when sowing mid-season rice. At this time, the spring shoots of tea trees develop fastest. If we ignore them, tea leaves will get old. As the saying goes, "Grain Rain picks less, but doesn't pick it in the long summer", so we should concentrate our efforts and harvest it by surprise in batches. The dry atmosphere and dry soil in North China and Northwest China often seriously affect the normal growth of crops. Especially, the dry hot wind before and after wheat filling and milk ripening is an important disastrous weather that leads to yield reduction, and timely irrigation is the key measure for drought resistance and disaster prevention.
