What is the solar term for growing rice?

A long summer. The long summer heralds the change of seasons and the official start of summer. After the long summer, the temperature in southern China rose rapidly, and the rainfall and the number of rainy days increased significantly, which became an important solar term in the peak season of crop growth. Before and after the long summer, it is the season of transplanting early rice in the north and south of the Yangtze River.

After entering the long summer solar term, the rainfall in the middle and lower reaches of the Yangtze River and South China increased rapidly in mid-May, and at this time, South China also entered the peak period of the first flood season. The rainstorm at this time often has the characteristics of continuity in time, extensiveness in region and fierceness in intensity. In the Pearl River system of Guangdong and Guangxi and the Minjiang River system of Fujian, the annual maximum water level often appears in this period, and there are folk sayings that it is long in summer, small in man, full in river and full in river.

Rice is divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice according to rice type. Divided into conventional rice and hybrid rice according to the way of seed retention. According to soilless culture, it can be divided into rice and floating rice. The main rice producing areas in China are Yangtze River Basin, Pearl River Basin and Northeast China. Rice is a direct cash crop.

Rice planting techniques, including paddy field and transplanting, were invented in China. Before planting rice, the paddy soil must be ploughed to make it soft. This process is divided into three stages: rough tillage, fine tillage and leveling. Farmers first cultivate seedlings in a field, which is usually called a paddy field. After sowing rice seeds, most farmers will sprinkle a layer of rice husk ash on the soil. When the seedlings grow to about 8 cm high, they can be transplanted.
