The fertile land in the north-east is an important commodity-producing area of the country, with rice as its important food crop. So, how many pounds of northeast rice acre? This paper briefly describes the main rice-producing areas and farming systems in the north-east。
How much is northeast rice acre
In the case of conventional cultivation, the production of rice in the north-east is generally about 800-1,000 pounds/acre. General production in the south-east is relatively low, at around 1,300-1500. Of course, this data is not produced and is related to species, soil environment。
Disturbing reports indicate that more than 2,000 pounds of acre were produced in the songhua river basin, but it should be noted that only one season of crops can be cultivated in the north-east。
The production of green or organic rice is relatively low, generally not exceeding 1,000 pounds, or even 200-300 pounds, but relatively high prices make it cost-effective to grow such rice。
Main rice-producing areas in the northeast
1. The north-east rice region is located in the liaodong peninsula (east of the yangtze and north of the great wall), which includes the whole of heilong river and jilin province, as well as most of liaoning province and the north-eastern part of inner mongolia。
Liaoning province has four rice areas, i. E. The liao river plain, the south-east coast, the liaodong qingyin mountains and the liaoxi low hilly hills, of which the area of rice in the liao river plains has a larger area of rice cultivation of about 7 million acres, with higher levels of single production。
3. The core area of rice production in the north-east is the junction of the plains of the three rivers (heilong, songhua and ursuri), which is suitable for rice growth. The land in the north-east is black soil, which is more nutritious and provides sufficient nutrients during rice growth。
4. In the north-eastern region, sufficient light and high temperature between day and night contribute to the accumulation of nutrients in rice. After winter, it can last up to six months, which greatly reduces the incidence of pests and diseases。
Rice farming systems in the north-east
One year of north-east rice (i. E. One year of ripening), because of the harsher climate in the north-east and the vulnerability to cold temperatures, which affect the productivity of rice。
The planting of rice in the north-east usually takes place in the middle of april each year and, because of the short spring and summer periods in the area, rice requires longer periods of sunlight and accumulation of temperatures, resulting in a growth cycle of around 200-240 days。
The north china region is also growing single-season rice, mostly before it becomes clear, and it can be moved between the end of april and the beginning of may. If the conditions are appropriate, planting may be carried out during the rain。
Before seeding, healthy and disease-resistant seeds should be selected for planting, and then ploughed with pharmaceutical preparations for two to three days, both to kill the fungus and to increase the vitality and growth of seeds。
