Rice planting time is different from that of early, middle and late rice.

Rice can be divided into early, middle and late rice according to the yield season, with early rice sowing at the end of March and early April, medium rice at the beginning of April and late rice at the end of May, and late rice in mid-late June. Rice can also be planted in different time periods according to different regions. for example, two cropping rice is generally planted in the south of the Yangtze River. the first cropping rice is sown in early April and harvested in early July, and the second cropping rice is sown in early July and harvested in mid-October.

I. Rice planting time

1. Early rice

The seeds are usually sown at the end of March and the beginning of April, and the harvest season is in mid-late July. When it is determined that the climate temperature is stable at about 13 degrees, the sowing of early rice can be started. for example, the Yangtze River basin is most suitable for sowing from late March to early April. It is generally cultivated earlier, the mature time is also early, the growth period is about 90-120 days.

The suitable planting areas of early rice are mainly distributed in the south, such as Hunan, Guangxi, Guangdong and other places. The rice produced by early rice is also called early rice or early rice, which usually has a cross taste and is often used for industrial grain or grain reserves.

2. Medium rice

The seeds are usually sown at the beginning of April and the end of May, and the harvest season is in mid-late September. Medium rice is suitable for planting in most areas, and its development varies greatly according to different regions and climates. the general growth period is about 120-150 days. The seedling raising mode is mainly wet seedling field and two-stage seedling raising. The taste of medium rice is better than that of early rice and late rice. The suitable planting areas of medium rice are mainly distributed in most areas of China except Guangdong, Qinghai and Hainan, and the main producing areas are: Hunan, Jiangsu, Sichuan, Heilongjiang, Hubei, Yunnan, Chongqing and so on.

3. Late rice

Generally, the seeds are sown in the middle and last ten days of June, and the harvest season is in the first ten days of October. Its growth period is longer, and its maturity is late, its growth period is about 150-170 days. Its taste is not as good as medium rice, but better than early rice. The suitable planting area of late rice is similar to that of early rice, and it is mainly planted in the south.

II. Rice planting process

1. Soak the seeds before planting rice. Soak the seeds in water for 2-3 days and wait for them to sprout. The soaking time is determined by the air temperature. if the temperature is high, the soaking time is short, and if the temperature is low, the soaking time is long.

2. The grain seeds with white buds are laid flat in bamboo baskets, then covered with plastic film, and then the seedlings can be raised in rice fields when they grow longer white buds.

3. Before raising seedlings, the rice fields must be ploughed and raked. There must be a lot of water in the rice fields. If anyone wants to pass the seeds, there will be no rice without water.

4. About half a month after raising the seedlings, when the seedlings grow to about 10 centimeters, they can be transplanted.

5. Water storage, ploughing, raking and other related work should be carried out on the rice field before transplanting, and the seedlings can be pulled and planted after the field work is completed.
