Why is Northeast rice, the most important origin of rice cultivation, famous?

As we all know, rice is the staple food of our lives, although there are some differences between the north and the south, the north is mostly pasta-based, while the south is dominated by rice. And why is Tohoku rice, the origin of rice cultivation, famous? Naturally, there are many factors that affect itFor example, the support of the country's political and economic system, environment, climate, soil, etc. are all factors that affect the quantity and quality of rice.

With this, let's take a closer look at the reasons why Tohoku rice is famous.

First of all, the climate of the Northeast region is monsoon climate, rain and heat at the same time, high summer temperature, sufficient water, very suitable for the growth of rice, when the rice gets sufficient water and heat, it will grow very well. Of course, the population in Northeast China is also very dense, the labor force is sufficient, and with the development of science and technology, the level of science and technology has gradually improved, which has also provided more labor force for the development of rice. Only sufficient climatic conditions and long sunlight hours can improve the quality of rice, making it more palatable and tasty.

Secondly, the Northeast region has fertile soil. Because the Northeast region is rich in black soil resources, the nutrient content of the black soil is very high, it can be said that it is the most nutritious soil in China, because the black soil is formed by the formation of humus after a long period of corrosion after the death of surface vegetation under cold climate conditions, with high organic matter content, fertile soil and loose soil, and the large area of Northeast China is also the area with the most black soil in China, so the yield of rice in Northeast China is high, which is the second reason why it is famous.

Finally, the Northeast is flat. The Northeast Plain is the largest plain in China, and the Northeast Plain not only has a flat and broad terrain, but also has a monsoon climate, sufficient light and heat, which provides a broad land area and climatic conditions for the sound field of Northeast rice. The reason why Northeast rice will be famous, there is also the support of the country's political economy, and more importantly, it is blessed with a unique environment, rice not only has a high yield, but also has a high quality quality, giving people a good taste, and eating rice in other places is a gap in texture and taste.

Northeast rice is good because of the geographical location leads to a good growth climate, fertile soil provides sufficient nutritional conditions for rice, sufficient sunshine, good water quality, irrigation water pollution formed by groundwater and river water, long accumulated temperature time and a year of harvesting, the growth period is generally about five months, the temperature difference between day and night is large, and there are few pests and diseases.

The northeast region of China, with flat terrain and large per capita cultivated land, is suitable for large-scale and commercial production of excellent rice varieties.

Because the Northeast has abundant land resources, including the black soil of Wuchang, the Wuchang rice grown is the world's top rice.

Because of the cold weather, the long freezing period can only produce one crop of rice, which determines the most important factor in the quality of the production.

China. Rice originated in China and gradually spread to other parts of the world. The history of rice cultivation can be traced back to Hunan, China, about 12,000 to 16,000 BC.

In 1993, a Sino-American joint archaeological team discovered the world's earliest ancient cultivated rice in Yuchanyan, Daoxian County, about 14,000 to 18,000 years ago. After rice was widely cultivated in China, it gradually spread westward to India and was introduced to southern Europe in the Middle Ages. According to different methods, rice can be divided into indica and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice.

Chinese scientist Yuan Longping has made great contributions to the research of hybrid rice and is known as the "father of hybrid rice".

Range of distribution of rice:

Rice is also cultivated in China, Japan, the Korean Peninsula, Southeast Asia, South Asia, the Mediterranean coast, the southeastern United States, Central America, Oceania, and parts of Africa, as well as along rivers in northern China. That is, rice grows almost everywhere except Antarctica.

The country with the largest area of rice cultivation in the world is India, with nearly 50 million hectares and a total production of 150 million tonnes.

China's rice cultivation area is about 30 million hectares, ranking second in the world, but China is the country with the highest rice production in the world, with a total output of more than 200 million tons.

The fruit of rice is rice, and after the rice is hulled, it is called rice, fragrant rice, and rice. Nearly half of the world's population feeds on rice. There are various ways to eat rice, including rice, rice porridge, rice cakes, rice cakes, rice wine, etc.

In addition to being edible, rice can also be used as industrial raw materials for brewing and sugar, and rice husks and rice stalks can be used as feed. The main rice producing areas in China are mainly the Northeast China, the Yangtze River Basin, and the Pearl River Basin. It is a direct cash crop.

It is also the staple food of one-third of the world's human race.

Most of the Northeast is located in the humid and semi-humid monsoon climate zone of the temperate zone. Sufficient precipitation, rain and heat at the same time, evaporation is small, easy to grow rice. The Northeast region is rich in land resources, and the Northeast Plain is the largest plain in China, with fertile soil.

The fertile black soil in Northeast China provides excellent conditions for agricultural production and the production of high-quality rice. I didn't guess that it contained 3, and the river network in the north area of Dongkuxiao was dense, and the abandoned water source was particularly conducive to planting rice. Monsoon paddy field agriculture in Asia has the following characteristics:

One is smallholder farming; second, the output per unit area is high, but the commodity rate is low; third, the level of mechanization is low; Fourth, the amount of water conservancy projects is large; fifth, the level of science and technology is low; Sixth, rich experience in planting.

The planting advantage of Northeast China is that the soil is fertile, the cycle is long, and the geographical environment is very suitable, so the rice in Northeast China is more delicious.

Some of the soil in the Northeast is very fertile, most of the Northeast is black soil, their land is very fertile, especially suitable for the cultivation of rice, in addition to the environment of the Northeast is also very suitable for rice planting, plus the cultivation area of the Northeast is relatively large, and is very suitable for the development of specialized and mechanized agriculture, which has very favorable conditions for cultivating high-quality rice in the Northeast; That's because of the good water resources and fertile land conditions in the Northeast, the rice grown in the Northeast is so sweet.

This rice variety is very good, the nutritional value is very high, and the taste is also very good, which is mainly related to the variety, but also related to the characteristics of the soil.

At present, all rice varieties are hybrid rice sources, and the more famous Northeast rice variety is Wuyou Rice No. 4. Northeast rice is mainly produced in Heilongjiang, Liaoning, Jilin and other vast plains, with full grains, green and white color, hard texture, rich fragrance and other characteristics.

Tohoku rice is a hybrid rice.

Strictly speaking, all rice varieties, including Tohoku rice, are currently hybrid rice. During the "Eleventh Five-Year Plan" period, in order to meet the growing needs of life, China has continuously developed and cultivated a variety of excellent rice varieties, among which the more famous Northeast rice variety is Wuyou Rice No. 4.

Northeast rice belongs to japonica rice, which is mainly cultivated in Heilongjiang, Liaoning, Jilin and other vast plains. The soil in these areas is extremely fertile black soil, and there is also enough light and rain to provide excellent growing conditions for Tohoku rice.

The main characteristics of Northeast rice are full of grains, green and white color, hard texture, rich fragrance, and it contains very rich amylose, fat, vitamins and other nutrients needed by the human body, which is also one of the reasons why it is loved by many people.

If you have eaten rice in the south, you will know that there is a difference between heaven and earth. When you go home, you can only eat the real rice from the Northeast.

According to incomplete statistics from the agricultural department, the perennial rice planting area in the Northeast Rice Region is more than 5 million hectares, and all of them are conventional rice varieties at present.

Tohoku rice was originally a hybrid rice planted! A hybrid, of course!

Generally speaking, the rice planted in the south is an indica rice variety, with a short growth cycle, which can mature many times a year, and is called indica rice after hulling, with slender grains and low transparency of rice grains; In the north, most of the rice grown is japonica rice, which matures once a year and becomes japonica rice after being hulled, and the rice grains are short and relatively transparent. In fact, it can't be generalized like this, as mentioned earlier, the rice in the north tastes strong, so the rice made from the north is relatively full and delicious, and most of us will choose the northern rice to eat. And most of the places south of the Yangtze River are still dominated by indica rice, as mentioned earlier, indica rice can be matured many times a year, so indica rice is also divided into early rice and late rice, good quality late rice, cooked rice is also very good taste, most of these areas will be based on this kind of late rice.

There are also some southern rice that may be ground into flour and made into various rice noodles, rice noodles and so on, which are more widely used.

In fact, most of the rice in the south is sold in its own production areas. The rice in the south is relatively cheap compared to the northeastern provinces, and many southern urban rice has become the mainstream for self-sale, or the local farmers are harvested as grain storage at home, and they are not carried out.

Although some rice is branded as Tohoku rice, a lot of the rice is produced in the south, and some of the rice in the south is made into rice noodles, rice noodles, rice cakes, and other foods, and may also be exported to other regions.

The reason why rice is abundant in the Northeast is that the land is relatively fertile.

Rice planting technology

The crop likes high temperature, humidity and short daylight, and has low requirements for soil.

The south of China is the main producing area, and the northern provinces are cultivated.

1. Seed treatment.

Seed treatment is a prerequisite in planting technology, generally before planting, the selected seeds are cleaned and disinfected in potassium permanganate solution, and then placed in a mesh bag for germination treatment, and the temperature can be maintained at about 30 to germinate quickly.

2. Land preparation treatment.

To ensure the fertility of the cultivation medium, generally in the land preparation should be combined with the cultivation and weeding treatment, and then add an appropriate amount of organic fertilizer and superphosphate, potassium sulfate and other fertilizers to the soil, mix and stir evenly, and then add a small amount of Dixone for sterilization.

3. Transplanting treatment.

Transplant the germinated seedlings into the soil, do not cultivate too densely, keep the plant row spacing at about 10 cm, hold the seedling roots with your hands, and insert the root system into the soil.

4. Post-planting treatment.

If there is a lack of seedlings after planting, it is necessary to replenish the seedlings in time to ensure the original planting density, and frequent irrigation treatment is required during the growth period, and the water can be increased during the seedling period, generally only need to be submerged to one-third of the plant, and then the ammonium sulfate fertilizer can be added appropriately according to the growth situation.

5. Weeding treatment.

It is best to carry out weeding treatment frequently after planting, and herbicides can be applied to it one week after planting, mainly oxatrione, and when the growth is better, benzylthioyl herbicides can be added to the fertilizer to mix and spray to avoid weeds affecting the normal growth of plants.

The largest planting area of rice is: Jiansanjiang Reclamation Area, with a total area of 10,000 square kilometers, accounting for 22% of the entire Heilongjiang reclamation area, with fertile soil, rich in green and high-quality rice, and is a modern agricultural demonstration area.

The largest cultivation area is in the Sanjiang Plain of Heilongjiang, China. This is also the largest cultivation of rice.

The largest rice planting base is the Beidacang base in Heilongjiang, which is the largest production base in the country.

The largest planting area of rice is in Heilongjiang, because the land of Heilongjiang is black soil, which is very nutritious and very suitable for growing rice.

I think the largest rice cultivation area is in the Jiansanjiang reclamation area, because the local rice production is very large.

The place is in what is now Heilongjiang, which is also in China, and it is now the largest rice plantation.
