The hybrid rice studied by Yuan Longping is the most productive in the world.
-
Yuan Longping's three-line hybrid rice.

The highest rice production on all continents is in Asia.
China is a pioneer and leader in hybrid rice production, and rice production has always ranked first in the world and one of the world's major rice producing areas. According to the official data, China's rice cultivation is mainly concentrated in the Qinling Mountains and the south of the Huai River, and the Chengdu Plain, the middle and lower reaches of the Yangtze River Plain, the valley plain and delta of the Pearl River Basin are the main rice producing areas in China.
In addition, the three northeastern provinces, the Bazi Plain of Yunnan and Guizhou, and the coastal plain of Jiangsu, Zhejiang and Fu are also one of the concentrated rice producing areas in China. It is understood that according to the different climates, China's rice is divided into early double cropping rice area, late double cropping rice area, single cropping rice area, etc., to ensure a bumper harvest of rice.
It is understood that India has the world's largest rice field area, the world's largest arable land area, half of the country's land is arable land, is the world's largest rice producer.
Rice is mainly distributed in the Gangetic plain and the coastal areas of the Indian peninsula, covering 44 million hectares, if the level of agricultural technology is higher, the yield of radical rice will be greatly improved, in addition, Indian rice is also divided into two crops.
Other high-yielding rice producing countries
1. Vietnam
Although Vietnam is a very small country, but Vietnam is also a country with very developed agricultural production, Vietnam's rice irrigation water resources are mainly in China's Lancang River, flowing into Southeast Asia and becoming the Mekong River, it is because of the water resources of the Mekong River, as well as good heat supply, that Vietnam has become a big country in rice planting.
2. Indonesia
Indonesia is an archipelago country in southern Asia, Indonesia has an equator over the air, so Indonesia's climate is particularly hot and humid, there are many tropical rainforests in Indonesia, sufficient heat and abundant water resources, providing a good ecological environment for rice growth.
3. Thailand
Thailand is also a country with a lot of land and resources, Thailand has a lot of strange folk customs, but the Thai people have a special love for rice, especially Thai fragrant rice, which tastes sweet and delicious, and is liked by all countries around the world, and the Thai people attach great importance to the cultivation of rice, and the annual yield of rice is very high.

You can find out when you go to the market. The current rice is of high quality, and the constant is not bad!

Dr. Yuan Longping's invention of "three-line hybrid rice".
-
The world's three major rice-producing regions are mainly Asia, Africa and the Americas.
1. Germination treatment.
When planting rice, it is necessary to promote germination, first wash the rice seeds with full grains and free of diseases and pests in clean water three times, and then put them into a gauze bag. Tie the mesh bag with a string and hang it in the well water, and wait for the seeds to be exposed before taking them out.
2. Sow seeds and raise seedlings.
When raising rice seedlings, it is necessary to choose the soil with rich nutrients and deep soil layer as the seedling soil, and then sow the white rice seeds directly in the seedling soil. If the ambient temperature is too low, build an arched greenhouse above the seedling soil after sowing to allow the seeds to grow as soon as possible.
3. Transplanting and colonization.
After the rice seedlings grow to a height of 30 centimeters, they can be dug out with soil, washed in the soil at the roots of the roots in clean water, and then inserted into the rice field with sunny ventilation and good water retention. During the process of transplanting, it is best to control the distance between the plants to five centimeters, and ensure that there are two seedlings in each hole.
The growth process of rice
Before planting rice, the soil of the paddy field must be turned over to make it soft, and this process is divided into three periods: extensive tillage, fine tillage and capping. In the past, animal power and ploughing tools were used, mainly water buffaloes to prepare the land, but now more machines are used to prepare the land.
Farmers first cultivate seedlings in a field, which is often called a seedling field, and after sowing the rice seeds, the farmers most likely sprinkle a layer of rice husk ash on the soil. In modern times, seedling boxes are mostly used by special seedling centers to make rice seedlings grow, and good rice seedlings are the key to the success of rice farming. When the seedlings are about eight centimeters tall, they can be transplanted.

Rice is the main food for the southerners, so the state also attaches great importance to its yield, so which variety of rice is better? If you don't know, you can first learn about the current ranking of high-yielding rice varieties, and then I will introduce it to you.
Ranking of high-yielding rice varieties.
1. Hui Liangyou silk seedlings.
Variety introduction: The classic combination of "1892s * Wushan Silk Seedlings" inherits the excellent lodging resistance of Hui varieties, greatly improves the rice quality, and the variety is resistant to high temperature and low temperature, which can be said to be a rice variety with very good comprehensive quality. In terms of yield structure, the general yield per mu is 700 kg, and the high-yield field can reach 900 kg!
For the endless new market, it has been proved that the new sterile line does not have much advantage over the old sterile line, and the sterile line that has been tested by the market can endure. Here we also recommend you to plant a good variety of Huiliangyou silk seedlings, which is suitable for extensive planting.
2. Chip Liangyou 1377
Variety introduction: "chip 4155S R1377" combination, integrated chip system good disease resistance, excellent rice quality characteristics, "R1377" Huangyue silk seedling paternal implantation, so that chip Liangyou 1377 enhance lodging resistance at the same time, show the advantages of compact plants, good ripening and no premature aging. The growth period is about 136 days, the yield structure is very excellent, it is a high-yield, high-quality, good stress resistance rice variety, worthy of the "chip two excellent series of pinnacles!"
<>3, Huiliang Youhang 1573
Variety introduction: It can be described as aerospace breeding, "aerospace rice, made in the middle of the seed"! The king variety of the Hui system has good lodging resistance, moderate maturity (135 days), large spike and high seed setting rate, and excellent rice quality.
Generally, the normal yield per mu can reach 700 kg, which is suitable for ordinary farmers and large households for extensive planting. The variety of rice has a good appearance, long grain shape, length-to-width ratio, and good rice taste!
4. Quanyou 822
Variety introduction: At present, in the entire Quanyou series, Quanyou 822 has the best lodging resistance! This variety has a strong ability to withstand high temperatures, and the yield structure is very good!
The weight of 1000 grains is high, and the gram and rice quality are excellent. It is especially suitable for large-scale direct seeding and machine transplanting, resistant to extensive management, and has a yield potential of more than 900 kg in high-yield fields. The plant is short, has good stress resistance, looks good at falling color, and has good color change in the later stage.
5, Long Liangyou 1377
Variety introduction: "Longke 638S R1377" matching, has the reputation of "high-yield nuclear **", in 2014, Hainan Longping Hi-Tech all varieties of yield comparison, with 1923 pounds of dry grain per mu yield ranked first! Due to the long growth period of the variety, it is positioned to be planted in idle fields, and wheat stubble fields are not suitable for planting.
This variety has good lodging resistance, high seed setting rate of large spikes, and good transparency of rice. At present, Longliangyou 1377 is in the upper reaches of the Yangtze River, as well as the middle and lower reaches of the Yangtze River, and the South China rice area has passed the national examination, and is a good variety of the three countries!
From the above, we can also know that the yield of this rice variety is still very high, and the comprehensive quality is also very good, and it is also the first one of these kinds of rice, and the rice variety is still good. I don't know what kind of rice everyone grows?
