There is no transplanting on the summer solstice, and there is no hope on the winter solstice. Don't plant alpine millet and sweet potato at this time.

In ancient times, when people engaged in agricultural activities, they would manage their field work according to the traditional 24 solar terms. Based on years of experience and wisdom, countless agricultural proverbs about solar terms have been condensed. There is a folk saying that "no transplanting in summer, no seeing your mother in winter", and the experience of not planting alpine millet and sweet potato in summer should be observed.

There is no transplant in the summer solstice, and there is no hope for the mother in the winter solstice.

It is an old folk proverb in China that "no transplanting in summer, no looking at the mother in winter". In the northern hemisphere, the days from summer solstice are the longest, and those from winter solstice are the shortest. Therefore, it takes a long time to transplant rice seedlings from summer to day, and people participate the most. It's too short to visit relatives on the solstice in winter, so it's difficult to show mother-daughter affection. The solstice is the longest in summer and the shortest in winter. There is another reason, not transplanting rice in summer solstice. If we sow rice outside the summer solstice, the growth period, pollination period and fruiting period of rice will be affected, resulting in poor growth, high yield and even reduced production in a short growth cycle. These proverbs have condensed the wisdom of the ancient working people in China.

Don't plant alpine millet in summer.

There are many crops that are not suitable for planting from summer solstice, such as alpine millet. "There is no alpine millet from summer to the sun, and there are ten days of valleys on the flat land." In other words, by the summer solstice, it is no longer suitable for planting millet in mountainous areas with higher altitude. The main reason is that the high altitude and low temperature in mountainous areas will lead to the early entry into the cool season and shorten the growth period, which is not conducive to the growth and development of millet and is prone to empty shells. However, in a mild place, there are still 10 days from summer to the future, so growers should pay close attention to sowing. However, after the summer solstice, alpine millet is out of date. Summer solstice is usually a good time for crops to grow sturdily, so sow early.

Don't plant sweet potatoes on the solstice of summer.

Sweet potato is also not suitable for planting in summer solstice. Sweet potato, planted early, can grow early, delay seedlings and bear fruit. When wheat is harvested, that is, in the ear planting season, people turn over stubble in time to cultivate summer sweet potatoes. At this time, the cultivated sweet potatoes are all large in size and quantity. Agricultural proverbs say that the sweet potato planted with awn seeds weighs ten kilograms, and one sweet potato can bear about 10 kilograms, indicating high yield. However, on the solstice of summer, if sweet potato is planted, the seedlings of sweet potato may not grow long and the fruit is poor, just like some Mao Mao roots, so it is difficult to produce high yield. Therefore, in the summer solstice season, it is not suitable for planting sweet potatoes.
