Where do rice and wheat live, where are the main rice growing areas, and why

Wheat distribution: Northeast spring wheat area: including all of Heilongjiang and Jilin provinces and parts of Liaoning and Inner Mongolia.

Chunmai area in the north: Inner Mongolia is the main part of the whole area, including parts of Hebei, Shaanxi and Shanxi.

Northwest Chunmai area: This area is mainly in Gansu and Ningxia, including parts of Inner Mongolia and Qinghai.

Huanghuai winter wheat area: including all of Shandong, most of Henan, Hebei, Jiangsu, Anhui, Shaanxi, Shanxi, and parts of Gansu.

Winter wheat area in the middle and lower reaches of the Yangtze River: including most of Jiangsu, Anhui and Hunan provinces, all of Shanghai, Zhejiang, Jiangxi and Xinyang of Henan.

Southwest winter wheat area: including the whole territory of Guizhou, most of Sichuan and Yunnan, and parts of Shaanxi, Gansu, Hubei and Hunan.

Rice: The double-cropping rice cropping area in South China is located in the south of Nanling, the southernmost part of China. It includes the southern part of Fujian, Guangdong, Guizhou and Yunnan, as well as all of Taiwan Province, Hainan Province and Nanhai Zhudao.

The double-cropping rice cultivation area in Central China starts from the coast of the East China Sea in the east, reaches the western edge of the Chengdu Plain in the west, connects the Nanling Mountains in the south, and borders the Qinling Mountains and the Huaihe River in the north. It includes all or most of the 8 provinces (cities) of Jiangsu, Shanghai, Zhejiang, Anhui, Jiangxi, Hunan, Hubei and Sichuan and the southern part of Shaanxi and Henan provinces, which is the largest rice cultivation area in China.

The single and double cropping rice cultivation area of the Southwest Plateau is located in the Yunnan-Guizhou and Qinghai-Tibet Plateaus, and the eastern and western Hunan Plateaus of eastern Guizhou and western Hunan 4 The single-cropping rice cultivation area in North China is located in the north of the Qinling Mountains and the Huai River, south of the Great Wall, and east of the Guanzhong Plain, including Beijing, Tianjin, Hebei, Shandong, Henan, Shanxi, Jiangsu, and Anhui.

The early-maturing single-crop rice cropping area in Northeast China is located in the north of the Liaodong Peninsula and the Great Wall, and east of the Daxing'an Mountains, including all of Hei and Ji, most of Liaoning and northeast Inner Mongolia.

The single-crop rice cropping area in the northwest dry region is located in the west of the Daxing'an Mountains, north of the Great Wall, the Qilian Mountains and the Qinghai-Tibet Plateau. The Yinchuan Plain, the Hetao Plain, and the margins of the northern and southern basins of the Tianshan Mountains are the main rice areas.

China's rice is mainly distributed in the southern areas south of the Qinling Mountains and the Huai River, and wheat is planted in small quantities in the south, mainly in the north.

The main rice planting areas are in North China, Northeast China, and Southwest China. Because these places have a relatively warm climate, longer sunlight hours, and abundant water quality, they are very conducive to the growth of rice, which can provide favorable conditions for rice growth and ensure sufficient yield and high quality.

The main planting areas of rice are distributed in Beijing, Shanxi, Shandong, Shaanxi and other places; Because the temperature in these areas is suitable for the growth of rice, photosynthesis is relatively strong, the soil is suitable for rice cultivation, and the climate and environment are suitable.

The main rice cultivation areas are in Xinjiang, Heilongjiang, Fujian, Hainan, Guangdong, and Guangxi. The environment in these places is very suitable for growing rice. There is also plenty of moisture.

No. Wheat is neither rice nor rice, the fruit of rice is rice, rice is called brown rice after removing the glume husk, brown rice can be obtained by grinding the rice bran layer. Wheat is a general term for wheat plants, is a monocotyledon, is a kind of grass widely cultivated around the world, wheat fruit is one of the staple foods of human beings, ground into flour can be made into bread, steamed bread, biscuits, noodles and other food; After fermentation, it can be made into beer, alcohol, liquor (such as vodka), or biofuel.

Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin, vitamin A and vitamin C. Wheat is one of the three major cereals, almost all of which are eaten, and only about one-sixth is used as feed. The Lianghe River Basin is the first region in the world to cultivate wheat, and China is one of the first countries in the world to grow wheat.

In 2010, wheat was the world's second-most produced food crop (6. 5.1 billion tons), second only to corn (100 million tons).

Some areas can be copied at the same time.

Rice is planted and raided.

Wheat is due to the local climate that is suitable for both baibai and wheat

The growth is also suitable for rice growth.

Both rice and wheat like water, but the wheat grows in moist soil, while rice grows in water for the entire growth period before maturity and cannot do without water.

In some areas, the two crops can be grown at the same time, wheat needs to be irrigated 3 to 4 times during the growth period of more than 4 months, and the soil is always moist, and rice is soaked in water almost every day.

Climate issues.

Sichuan, for example, can. Rice prefers heat and humidity, whereas wheat does not need much water. So here rice is grown in the fields and wheat is grown in the soil.

As long as there is water, you can plant **, but the harvest is not so good in some places!

Wheat is mainly grown in the north and rice is mainly grown in the south.

It is called "South Rice and North Wheat".

Wheat cultivation techniques

The crop can grow well on both acidic and slightly alkaline nuclear soils, but the most suitable soil pH is to.

Cultivation and filial piety and land preparation

The land preparation of the crop in the dry land should be based on the deep tillage layer year by year, combined with the application of organic fertilizer, and the improvement of water and fertilizer conservation, and the land preparation should be carried out according to different multiple cropping forms. That is, the previous crop harvested earlier, such as spring corn, sorghum, tobacco, etc., the harvest should first be shallow tillage to eliminate stubble, and then deep ploughing of the kang soil, so that the stubble rots and accept the autumn rain, shallow rake after the rain, reduce evaporation; The other category, such as sweet potato, cotton, etc., has a tight harvest time, and if the conventional method is used, it is bound to delay the sowing date, which is one of the important reasons for the low yield of the crop in the southwest region. Therefore, on the one hand, the implementation of loosening soil and moisture between the rows in the previous crop and later period, and then plowing and leveling when planting wheat; On the other hand, it is advocated to dig potatoes, level the ground, fertilize, sow and other continuous operations to ensure that the crop is sown in a timely manner.

High-yield technology

1. Pay attention to the selection of high-fertilizer and water plots. High-yield and high-quality crop varieties require that soil nutrients must be comprehensive and sufficient to meet the needs of high-yield cultivation, so it is advisable to choose plots with high soil fertility and good watering conditions, increase organic fertilizer, and adopt formula fertilization technology.

2. Pay attention to late sowing at the appropriate time, and determine the appropriate basic seedlings according to the characteristics of the variety. It is necessary to prevent excessive sowing volume, resulting in passive post-management.

3. Pay attention to prevent lodging and reapply jointing fertilizer. Some of the high-quality crop varieties promoted are not resistant to lodging, especially for wheat fields with too large groups, a chemical control treatment must be carried out before returning to jointing, and paclobutrazol or wheat yefeng can be sprayed. It is necessary to reapply jointing fertilizer to control the formation of excess falling ears and promote large ears and more grains.

4. Pay attention to watering grouting water, wheat yellow water, and spraying foliar fertilizer to prevent premature aging. Watering grouting water plays an important role in increasing granularity weight and preventing dry and hot air. In dry weather, the use of wheat water is conducive to intercropping and preventing premature aging.

In the first half of May, combined with the prevention and control of pests and diseases, spray 2 to 3 times of foliar fertilizer, such as potassium dihydrogen phosphate, which can reduce the harm of dry and hot air and increase yield.

5. Pay attention to the prevention and control of pests and diseases. Generally speaking, high-quality crops are more susceptible to pests and diseases, such as sheathropathy, powdery mildew, and aphids occur earlier and heavier than conventional varieties. It should be prevented and treated as soon as possible according to the forecast.

6. Spray the crop treasure once when the crop has just broken and reached about 60% to 70% before heading and flowering, so as to activate the biological enzyme activity in the crop, promote coordinated growth, enhance the photosynthesis of functional leaves, significantly reduce the empty stubble rate, improve the seed setting rate and 1000-grain weight, so as to achieve the effect of increasing yield.

The Huanghuaihai region is the first planting belt of winter wheat, and the winter wheat planting area and slow index output here account for more than 7% of the country.

Huanghuaihai is located in the temperate monsoon climate zone, the average temperature of winter wheat growth period is 6-9, of which the overwintering period is relatively cold, the duration is long, the seedling stage undergoes overwintering, and the next year can be normal heading and flowering, and the cold weather is also conducive to killing overwintering pests. The average temperature of winter wheat in this region is about 20 from heading to maturity, which is suitable for wheat filling and firming. During the growth period of winter wheat, the precipitation here is 150-250 mm, which is moderate, which can meet the growth needs of winter wheat. The sunshine hours are 1500-2000 hours, and the sunshine is sufficient, which is conducive to photosynthesis and dry matter accumulation, and is not easy to induce disease.

Rice - the region south of the Yangtze River, the northeast region.

The south of the Yangtze River has a warm and humid climate, abundant heat, sufficient moisture and suitable light, and is the best planting belt for rice. In the south of the Yangtze River, the average temperature of rice growth period is about 26, the accumulated temperature of 10 years is above 3500 ·d (degrees Celsius·day), the precipitation is 600-1000 mm, the sunshine hours are 600-900 hours, the water and heat are sufficient, and the light is suitable, which is conducive to the growth and development of rice.

The average temperature of rice growth in Northeast China is about 22-24, and the heat is more suitable. However, the rice growing season here is long, the sunshine is sufficient (1200-1300 hours), and the temperature difference between day and night is large during the grain filling period, which is conducive to the synthesis and accumulation of dry matter, so it has become a high-quality rice production area in China.

Rice is suitable for cultivation in the south, and wheat is suitable for cultivation in the north.

The so-called "South Rice and North Wheat".

Rice cultivation techniques

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

In order to ensure the fertility of the cultivation medium, it is generally necessary to combine the cultivation and weeding treatment when preparing the land, 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

The germinated seedlings are transplanted into the soil, do not cultivate too densely, keep the plant row spacing at about 10 cm, hold the seedling roots by hand, insert the root system into the soil, it is best not to be too shallow, the root system should be kept completely covered by the soil, and it can also be carried out with a seedling machine, which is faster.

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.
