芒种，是二十四节气中的第九个节气，也是夏季的第三个节气。每年公历6月5日至7日之间，当太阳到达黄经75度时交节。芒种的名称源自农事活动，"芒"指有芒的谷类作物如稻、黍、稷、麦等，"种"即播种之意。《月令七十二候集解》记载："五月节，谓有芒之种谷可稼种矣。"此时北方麦类等有芒作物已经成熟，南方晚稻等谷类作物正是播种的时节。芒种是农业生产的分水岭，既是收获的季节，也是播种的关键时期，"芒种不种，再种无用"这句农谚深刻体现了这一节气在农事活动中的重要性。此时气温显著升高，雨量充沛，是农作物生长最旺盛的时期。

Grain in Ear (Mangzhong) is the 9th solar term among the 24 solar terms and the third solar term of summer, occurring around June 5-7 annually when the sun reaches 75 degrees celestial longitude. The name "Mangzhong" derives from agricultural activities - "mang" refers to awned grain crops such as rice, millet, and wheat, while "zhong" means sowing. The "Collected Explanations of the Seventy-Two Pentads" records: "Fifth month node, meaning awned grain crops can be sown now." At this time, northern awned crops like wheat have matured, while southern grain crops like late rice are precisely in sowing season. Grain in Ear is a watershed in agricultural production, both a harvest season and a critical planting period. The agricultural proverb "if not planted by Grain in Ear, planting later is futile" profoundly embodies this solar term's importance in agricultural activities. Temperatures rise significantly, rainfall becomes abundant, marking crops' most vigorous growth period.
