Whether winter wheat or spring wheat is sown in the Tarim Basin

They were wrong!! Plant spring wheat because the winter in the Tarim Basin is too cold, and the annual difference is large.

The south of the Tianshan Mountains in Xinjiang belongs to the warm temperate zone, with an active accumulated temperature of more than 3400, with winter wheat as the main crop and cotton as the main cash crop.

Spring wheat, spring wheat is mostly distributed at higher latitudes or altitudes. The areas with poor thermal conditions are mainly distributed in the Northeast Plain in the middle temperate zone in China. Hetao Plain. Xinjiang and Qinghai-Tibet.

Winter wheat is in the north, mainly distributed in the north of the first line of the Huai River in the Qinling Mountains, the south of the Great Wall, and the winter wheat area in the south is mainly distributed in the south of the first line of the Huai River in the Qinling Mountains.

Generally, it is in the north, north of the Huai River in the Qinling Mountains, and then in the south of the Great Wall, because the winter wheat in this place has reached 60%, and the planting area is relatively large in Henan and Hebei.

Most are found in the north. The climate here is ideal for the survival of winter wheat and is also a good way to increase yields.

Henan, Shandong, Hebei, Jiangsu, Sichuan, Anhui, Shaanxi, Hubei, Shanxi.

Good evening in China's three major wheat producing areas: 1The northern winter wheat area is mainly distributed in the north of the Qinling Mountains and the Huai River, and the south of the Great Wall, where the winter wheat output accounts for about 56 percent of the total wheat output in the country. Among them, they are mainly distributed in Henan, Hebei, Shandong, Shaanxi, and Shanxi provinces and regions;

2.The winter wheat area in the south is mainly distributed in the south of the Huai River in the Qinling Mountains. This is the main rice producing area in China, and planting winter wheat is conducive to improving the multiple cropping index and increasing grain production. It is characterized by a high rate of goods. The main producing areas are concentrated in Jiangsu, Sichuan, Anhui and Hubei provinces.

3.Spring wheat area, mainly distributed in the north of the Great Wall. The temperature in this area is generally low, the production season is short, so it is mainly one crop a year, and the main producing provinces and regions are Heilongjiang, Xinjiang, Gansu and Inner Mongolia.

Spring wheat and winter wheat in China are roughly bounded by the ancient Great Wall, with spring wheat mainly planted in the north of the Great Wall and winter wheat in the south of the Great Wall.

FYI.

I generally like to sit and watch.

1) In the curve of Figure B, only respiration is carried out before 6 o'clock in the morning, and the soybean seedlings begin to photosynthesize at 6 o'clock, so the reduction of oxygen in the small room gradually decreases at 6-8 h At point B, the photosynthetic rate reaches the highest time of the day, if the soybean seedlings under the light at point B are moved to the dark, the light reaction is immediately blocked, and the ATP and [H] produced are reduced, thereby inhibiting the reduction of C3 in the dark reaction, resulting in an increase in the content of C3 in chloroplasts in their cells (2) Since magnesium is the main component of chlorophyll synthesis, if soybean seedlings are cultured in a full nutrient solution with magnesium deficiency, the chlorophyll content of soybean seedlings will decrease, the photosynthetic rate will be slowed down, and respiration will not be affected, so point A in the curve of Figure B will shift to the right (3) Due to the high sunlight time and light intensity of Baisui in Xinjiang, more organic matter is synthesized during the day, and the temperature at night is low, and the organic matter consumed by respiration at night is less, so more organic matter is accumulated in a day. (4) Because the way in which root cells absorb inorganic salts is active transport, active transport requires energy consumption, and loose soil can promote aerobic respiration and energy supply of root cells Therefore, the answer is: (1) soybean seedlings begin to photosynthesize (2) right Lack of chlorophyll in plants (3) Light time (light intensity) and temperature difference between day and night (4) Promote aerobic respiration of roots and absorption of inorganic salt ions by roots.

Summary. Dear, hello, 1. The planting time of winter wheat.

Winter wheat will be sown in September-October in 2020 and harvested in April-May of the following year.

2. Winter wheat planting technology.

1) Pre-sowing preparation: wheat varieties with high yield, stable yield, excellent yield and strong stress resistance should be selected; Before sowing, seed coating or pesticide dressing is required to reduce the incidence of seedlings.

2) Land preparation and fertilization: If it is a freshly harvested corn plot, the corn stalks need to be crushed and returned to the field; At the same time, it is also necessary to apply basal fertilizer according to the yield per mu, generally 10-156 kg of nitrogen fertilizer, 4-8 kg of phosphate fertilizer and potassium fertilizer per mu.

3) Reasonable sowing: sowing wheat too early or too late will affect the yield of wheat, so it is necessary to master the appropriate sowing time; Moreover, when sowing, the method of strip sowing can be adopted; When sowing, the next seed should be even, and the depth should be consistent.

4) Cultivating strong seedlings: When winter wheat emerges, it is necessary to check the seedlings and replenish the seedlings in time, and if the soil is agglomerated, it is necessary to loosen the soil in time.

The fresh winter wheat is planted in the winter, and it will be able to come out next year.

Dear, hello, 1. The planting time of winter wheat in 2020 is sowing winter wheat in September-October, and it can be harvested in April-May of the following year. 2. Planting technology of winter wheat (1) Pre-sowing preparation: wheat varieties with high yield, stable yield, excellent yield and strong stress resistance should be selected; Before sowing, seed coating or pesticide dressing is required to reduce the incidence of seedlings.

2) Selling and fertilizing the soil preparation residue: if it is a newly harvested corn plot, the corn stalks need to be crushed and returned to the field; At the same time, it is also necessary to apply basal fertilizer according to the yield per mu, generally 10-156 kg of nitrogen fertilizer, 4-8 kg of phosphate fertilizer and potassium fertilizer per mu. (3) Reasonable sowing:

Sowing wheat too early or too late will affect the yield of wheat, so it is necessary to master the appropriate sowing time; Moreover, when sowing, the method of strip sowing can be adopted; When sowing, the next seed should be even, and the depth should be consistent. (4) Raising strong seedlings: When the winter wheat emerges, it is necessary to check the seedlings and replenish the seedlings in time, and if the soil is agglomerate, it is necessary to loosen the soil in time.

Generally, after sowing, winter wheat will be sold and dug seedlings in 6-10 days, but the specific seedling rental time of winter wheat will vary due to different temperatures, sowing depths and soil moisture.

Wheat can be grown.

In the process of wheat cultivation, fertilizer has a great impact on yield and quality. Specially designed wheat topdressing should be adapted to local and seedling conditions, and fertilizer and water management should be carried out scientifically.

1. For wheat fields with normal growth and high fertility level, jointing fertilizer should be reapplied in combination with watering at the jointing stage.

2. For medium fertility wheat fields, potassium dihydrogen phosphate can be sprayed in combination with watering at the rising stage to improve the utilization rate.

3. On the basis of hoeing in early spring, top dressing should be carried out twice at the regreening stage and jointing stage on the basis of hoeing in early spring, so as to promote spring tillering and panicle, improve the panicle formation rate, promote the development and fruiting of florets, and increase the number of grains per panicle.

4. For the late stubble seedlings that have not been applied base fertilizer or have a small amount of fertilizer at the time of sowing, they should be topdressed by moisture when the soil has just thawed, but it is not advisable to water back to green water, so as not to cause the ground temperature to drop and the soil permeability is poor, which will affect the growth of wheat plants. On the basis of fine hoeing, fertilizer and water promotion can be carried out in the early stage of wheat rising. Watering should be carried out when the average ground temperature is stable at about 5 to avoid frost damage prematurely.

At the same time, the new high-fat film can protect moisture, prevent water evaporation, protect against sun and drought, heat preservation and frost, and prevent soil layer compaction.

Wheat is the main grain crop in China, of which winter wheat accounts for more than 80% of the sown area of wheat.

Now it is about to enter the winter wheat planting period.

So, when is winter wheat planted and harvested? Winter wheat is mainly distributed in **? Let's take a look.

Winter wheat planting and harvest time: Wheat is divided into two types: winter wheat and spring wheat according to the sowing date.

Winter wheat is the main source in China.

The sowing time of winter wheat in China is about mid-to-late September to early October, and the sowing time of spring wheat is after the Spring Festival.

The sowing time of winter wheat in China is about mid-to-late September to early October, and matures from the end of May to mid-to-late June of the following year.

Winter wheat in the growth process of the ability to resist the cold is very strong, its seedlings can survive the winter, when spring comes, the seedlings divide quickly, squat to grow up, winter wheat grinding powder is very delicious.

The sowing time of spring wheat is after the Spring Festival, the drought resistance of spring wheat is very strong, the plant is short and the spike is large, the growth period is short, and it is suitable for spring sowing, but it is not as delicious as winter wheat flour.

Winter wheat is mainly distributed in the north, winter wheat is mainly distributed in the Qinling Mountains, north of the Huai River, south of the Great Wall, mainly distributed in Henan, Hebei, Shandong, Shaanxi, Shanxi provinces and regions.

Winter wheat in southern China is mainly distributed in the south of the Huaihe River in the Qinling Mountains, and the main producing areas are concentrated in Jiangsu, Sichuan, Anhui and Hubei provinces.
