Introduction to Rice

Rice is a plant of the genus Oryza. The fruit of rice is rice grain. After the rice grains are husked, it is called brown rice. Brown rice is ground to remove the bran layer to get rice, which is another name for rice. The unhusked rice can be called rice, rice grains, and millet.

Rice can be divided into glutinous rice and non-glutinous rice, indica rice and japonica rice, early rice and medium and late rice. According to the seed retention method, it can be divided into hybrid rice and conventional rice. In addition, it can be divided into floating rice and paddy rice depending on whether it is grown in the soil.

Rice growing conditions

Rice prefers a warm and humid environment. The average temperature during the growing period is between 18 and 25 degrees. The average temperature in the hottest month in rice-growing areas across the country is generally above 20 degrees, and is often distributed in tropical and subtropical monsoon climate areas.

Suitable areas for rice cultivation

Rice prefers a warm and cool environment and is widely grown on plains with sufficient water and sunshine, such as the middle and lower reaches of the Yangtze River in my country, where it is planted on a large scale.

Rice planting time

Rice can be divided into early, middle and late rice according to its production season. Early rice is generally sown in March and April, middle rice is generally sown in April and May, and late rice is generally sown in June. You can also choose different time periods to plant rice according to different planting sites. Southern regions generally plant two seasons of rice, with the first season sown in April and the second season sown in July.

Rice Planting Benefits

The input-output ratio of planting single-season rice is 1:1.52~1.77, and the input-output ratio of planting double-season rice is 1:1.48~1.63. The cost of double-season rice is large and the income is low. In addition, the income from single-season rice is large and will not be affected by the season, while the risk of planting double season rice is higher and is restricted by climatic conditions.

For large-scale planting and management companies, under the condition of a certain area of ​​rice fields, the arrangement of the areas of early, medium and late rice should be adapted to local conditions. In mountainous areas, the soil fertility is poor and transportation is inconvenient, so it is advisable to plant more medium rice (or late rice). In plain areas, the soil is fertile, so it is best to plant double-season rice.
