Northeast rice is believed to be familiar to everyone and is one of our important staple foods. In recent years, northeast rice has been popular all over the country because of its unique advantages, which plays an important role in human health. So, what is the growth process and environment of rice in Northeast China? Below, I will give you a careful analysis (note: the following content takes Jilin rice as an example).

Methods/steps

The eastern part of Jilin Province belongs to the transition zone from Changbai Mountain area to hilly area, with a warm monsoon climate and a forest coverage rate as high as 50%. The soil is mostly composed of forest humus and fire ash, which is soft and fertile, with high organic matter and mineral content, drainage and ventilation. Irrigation water is water flowing down from the mountain. The produced rice has excellent quality and good taste, and all physical and chemical indexes are superior to the national standards.

Songnen Plain in the west is rich in light and heat resources, and the soil is mostly alkaline black oil soil. The PH value of soil and water is higher than 7, with high organic matter content, rich trace elements and no pollution. After years of ripening improvement and water diversion, the produced rice is very suitable for rice growth, rich in nutrition and good in taste. It belongs to weakly alkaline food, which is beneficial to human health, can enhance the immunity and vitality of the body, and prevent and treat hyperacidity, joint pain, renal function and other problems.

The Songliao Plain in central China is rich in light and heat resources, with humid and rainy summer and warm climate. In autumn, the weather is short, cool, sunny and the temperature difference between day and night is large, which is beneficial to the nutrient accumulation of rice. Mainly irrigated by the upper reaches of Songhua River, Liaohe River and Nenjiang River, it is rich in water resources, clear in water quality, fertile in soil, deep in black soil layer, high in organic matter content, good in soil permeability and strong in water and fertilizer conservation, which is very suitable for the growth of japonica rice.

Meihe Rice: meihekou city has superior natural conditions, good water quality and fertile land; Pollution in rice planting areas in baili. Every spring, flocks of egret migratory birds fly over the green rice fields, and at night bursts of frogs accompany you to sleep. It is known as the "Egret Frog Field". After testing, Japanese companies believe that the appearance, aroma, taste, viscosity and hardness of Akita Otsuka rice planted in Meihekou are not only better than many famous domestic brands, but also better than Akita Otsuka rice produced in Japan, with a taste score of 85 points. The cooked rice is fragrant, soft, smooth, chewy and delicious.

Liuhe Volcano Rice: Liuhe County is located in the mid-level mountain area. After years of weathering and erosion, a thick layer of humus has accumulated on the platform. Soft and fertile soil with high organic matter content is the best soil for rice production. Liuhe rice is green and shiny, and has a unique fragrance when steamed. It tastes soft and smooth, soft but not sticky, tough and palatable. Because the irrigation water of Liuhe rice comes from the mountain spring of Changbai Mountain volcano branch, it tastes sweet and flat, and it also has the functions of invigorating qi, invigorating the middle energizer, invigorating the spleen and nourishing the stomach, replenishing essence and strengthening the brain, harmonizing the five internal organs, dredging blood vessels, improving hearing and eyesight, relieving annoyance and thirst, and stopping diarrhea.

Yongji Wanchang Rice: Wanchang area between Yinma River and the lower reaches of Chalu River in Yongji County, with deep water and lush grass. The planted rice is irrigated by Xingxingshao Reservoir, and the water quality reaches the national drinking water standard. Polished rice is famous for its white and delicious taste. There is a folk saying that "the fork river japonica rice will not taste or break into grains after three times of cooking, which is called the top three waters".

Weakly alkaline rice: the normal pH value of human body fluids should be 7.35 ~ 7.45, which is weakly alkaline. Weak alkaline constitution is strong in immunity, energetic and sharp in thinking. If you eat too much acidic substances, your immunity will decrease, and people will be prone to fatigue, constipation, joint pain, and problems in lung and kidney function. As a staple food in China, rice is basically acidic (pH
