When does rice mature? When is the maturity time of rice?

1, rice is divided into early rice, middle rice and late rice, and there are some differences among them: early rice ripens in early July, middle rice ripens in late September and late rice ripens in early 10.

2. Indica rice: matured in September-65438+10, originally from subtropical zone. Widely planted in tropical and subtropical areas, the growth period is short, and it can be ripened many times during the frost-free period of one year. After hulling, it becomes indica rice with slender appearance and low transparency. Some indica rice varieties have red skins, such as Redmi produced in Jiangxi, China.

3. Japonica rice: Generally, it matures at the end of 10 to10, with less starch content. Widely planted in temperate and cold regions, it has a long growing period and generally ripens only once a year. After hulling, it becomes short and transparent japonica rice.

4. Upland rice: Upland rice is in upland fields, but there is little morphological difference and great physiological difference between rice and upland rice. The yield of upland rice is relatively low, and it is gradually replaced by rice, and a small amount of upland rice is planted in the northern region.
