What does it mean to have a small solar term in a year?

Most of the 24 solar terms can be defined by their names, but Xiaoman is somewhat puzzling. Originally, Xiaoman means that summer crops such as wheat are full of milk and seeds. Agricultural proverbs in southern China give Xiaoman a new meaning: "Xiaoman is not satisfied, he thinks about it"; Small is full of discontent, no matter what kind of mango it is. The word "full" is used to describe the amount of rain, and it is pointed out that if there is not enough water in the field when it is full, the ridge of the field may crack and even rice cannot be planted when it is planted. Because "transplanting rice in long summer and planting rice in small fields" and "seedlings rushing to small fields and autumn fields", small fields are suitable for rice planting. Whether the summer drought in South China is serious or not is directly related to the rice planting area. Planting sooner or later is closely related to the yield of rice. In the central and western parts of South China, there are often droughts in winter and spring, and heavy rains come late. In some years, the rainstorm didn't come until June, or even in July at the latest. In addition, there is not much rainfall in the small solar terms all the year round, with an average of only about 40 mm. The natural rainfall cannot meet the water demand for planting seedlings, which makes the summer drought in the water-deficient central and southern regions more serious. As the saying goes, "storing water is like storing grain" and "preserving water is like storing grain". In order to resist drought, in addition to improving cultivation measures and speeding up afforestation, it is especially necessary to pay attention to water storage and moisture conservation in the first year. However, we should also pay attention to the possible continuous rainy weather, which will affect the harvest and drying of spring sowing crops. In the mountainous areas of the northwest plateau, at this time, most of them have entered the rainy season, and crops are growing vigorously and thriving.
