Rice sowing season

Rice planting time is different in different places, some harvest in one season, and some harvest in two seasons. North China is a single-season rice. One-season rice must be sown before Qingming Festival and transplanted in late April and early May (if conditions permit, it can also be transplanted in Grain Rain). The sowing time of early-maturing single-season rice in Northeast China is about April.

The growth period of double-cropping rice in northern China is 104 days in the first season and 87 days in the second season. Generally, they are early-maturing varieties. Avoid winter.

Planting double-cropping rice in the north needs to cultivate extra-early-maturing varieties. In the first season, seedlings are raised from the middle of April in the solar calendar, and can be harvested in early August, which takes about 104 days. In the second season, rice is usually transplanted at harvest time. Harvesting before freezing;

Take the plain in the middle and lower reaches of the Yangtze River in South China as an example. Early rice is sown in mid-April, transplanted in early May, harvested in late July, and immediately transplanted with late rice (called double cropping). Generally, it must be finished before beginning of autumn, and the late rice will be harvested in late June. 1 1.
