Rice sowing solar terms

Early rice: sow in late March to early April and harvest in late June to July.

Late rice: sow from late June to July (immediately after early rice harvesting) and harvest from late June to late October165438+10.

The suitable sowing date of early rice is: the daily average temperature is higher than 65438 02 degrees Celsius for three consecutive days, and the suitable sowing date in the Yangtze River basin is from late March to early April. Generally, the growth period of early rice is 90 ~ 120 days, and that of late rice is 150 ~ 170 days. Due to the different climatic conditions in different regions, their sowing dates and harvest seasons are also very different. After harvesting early rice, we should immediately rush to plant late rice.

Extended data:

Once or three times a year in the north, twice a year in the south and three times a year in Hainan.

The Best Time for Rice Harvesting in South China;

Rice in Jiangsu three-line hybrid mid-season indica rice area is usually sown in the first half of May, with the maturity of 65438+1early October and the whole growth period of about 140 days. Rice can be planted in southern Jiangsu, with two crops a year, with early rice in late July and late rice in mid-late June 65438+ 10.

The upper reaches of the Yangtze River are dominated by single-season mid-season rice. Most of them are planted around Tomb-Sweeping Day, transplanted in early May (before and after long summer and before full harvest), and harvested in the middle and late August.

In the plain area of the middle and lower reaches of the Yangtze River, early rice is sown in early and middle April, transplanted in early May and harvested in late July, and then immediately transplanted with late rice (called double cropping rice). Generally, it must be finished before beginning of autumn, and the late rice will be harvested in late June. 1 1.

The Best Time to Harvest Rice in Northern China;

However, both northern and northern regions are single-season rice. One-season rice must be sown before Tomb-Sweeping Day and transplanted in late April and early May (Grain Rain can also be transplanted if conditions permit). Northeast China is an early-maturing single-season rice. Sowing time is around April. The growth period of double-cropping rice in the north is one season 104 days, and the second season is 87 days. 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, about 104 days. In the second season, rice seedlings are usually planted while harvesting. Harvest before freezing.
