What is rice?

Rice is an annual gramineous plant, which belongs to direct cash crops. In addition to being edible, it can also be used as industrial raw materials for wine and sugar, and rice husks and straw can be used as livestock feed. As the main food crop for human beings, there are also many varieties. For example:

Introduction of rice varieties

1. Indica rice

About 20% is amylose. Belongs to medium stickiness. Indica rice originates from the subtropics and is grown in the tropics and subtropics. It has a short growing period and can mature many times a year where there is a long frost-free period. After shelling into indica rice, the appearance is slender and the transparency is low. The skin of some varieties is red, such as the red rice produced in Jiangxi, China, which is dry and loose when cooked. Usually used for radish cake, rice noodles, fried rice.

two。 Japonica rice

Japonica rice has less amylose, less than 15%. Planted in temperate and cold zones, it has a long growing period and generally can only mature once a year. After shelling into japonica rice, the appearance is round, short and transparent (some varieties of rice have local powdery). The cooking characteristics are between glutinous rice and indica rice. It is used for general rice.

3. Early, middle and late rice

The fundamental difference among early, middle and late rice lies in their different responses to light, which can mature normally in all seasons throughout the year. Late rice is very sensitive to short-day light. The rice in the northern rice region belongs to early or medium rice.

4. Giant rice

Giant rice is erect in shape, with long spikes and many grains, round and full, with an average of 1.8 meters per plant and 2.25 meters high.

5. Seawater rice

Sea rice (sea rice): it is the visual name of saline-alkali tolerant rice, and it is a special rice growing in saline-alkali land such as beach. It does not grow in sea water or the sea, but is not afraid of short-term immersion in sea water.

In addition, as a major food crop for human beings, the research and development of new varieties has never stopped, and it is difficult to say how many varieties there are at present.
