Rice growing environment and local conditions

Rice growing environment and conditions

Rice generally grows in tropical, semi-tropical and temperate regions, and is often distributed in coastal plains, tidal deltas and river basins. It was originally distributed in China, and rice was planted in the Yangtze River Basin a long time ago. After being widely planted in China, rice spread to India.

Rice growing conditions

Rice prefers a high temperature and humid environment. It is a short-day plant and requires sufficient light during its growth period. If the maintenance environment lacks light, the yield will not be high and the quality will be poor. It is not very demanding on the soil, and paddy soil is the best.

Rice growing temperature

Rice likes a warm environment and is not cold-resistant. The lowest suitable temperature for germination is 10-12 degrees, and the optimum is 28-32 degrees. The most suitable temperature for panicle differentiation is around 30 degrees, the suitable temperature for heading is 25-35 degrees, and the optimum temperature for flowering is around 30 degrees. If the temperature is below 20 degrees or above 40 degrees, the growth will be poor.

Rice growth process

The life of rice begins with seed germination, goes through rooting, leaf growth, tillering, jointing, panicle formation, flowering, and fruiting, and finally forms new seeds. This is called the life of rice. The life of rice is divided into four periods: seedling stage, greening and tillering stage, jointing and heading stage, and heading and fruiting stage.

Rice Planting Time and Method

1. The planting time of rice can be early or late. Early rice is generally sown in March and April, medium rice is sown in April and May, and late rice is sown in mid-June. You can also choose different time periods for sowing according to different planting conditions. For example, the area south of the Yangtze River generally grows two seasons of rice, which are mainly sown in early April or early July.

2. Before planting rice, you need to renovate the soil to make it loose, then sow the seedlings in the nursery field. When they grow to 5-8 cm in height, transplant them to the field, and then carefully maintain them before harvesting.
