How to distinguish between winter wheat and spring wheat, and how to distinguish between winter whea

Winter varieties: extremely sensitive to temperature requirements, the suitable temperature in the vernalization stage is 0 5, and it takes 30 50 days, of which only the varieties that can pass the vernalization stage after more than 30 days under the condition of 0 3 are strong winter varieties. Seeds that have not undergone the vernalization stage cannot be tasseled in the spring.

Semi-winter variety: The temperature requirement is between winter and spring. Under the condition of 0 7, after 15 to 35 days, the vernalization stage can be passed. Seeds that have not undergone vernalization cannot be tasseled in spring or are delayed, the heading is not neat, and the yield is very low.

Vernal varieties: When passing through the vernalization stage, the temperature requirements range is wide and the experience time is shorter. Generally, 0 12 is required in the autumn sowing area, and 0 20 is required in the northern spring sowing area, and the vernalization stage can be passed after 15 days.

The difference between winter wheat and spring wheat is mainly that the sowing time is different, and the quality is basically the same, winter wheat is sown in autumn, and it is basically mature in the spring of the next year, and then late rice can be planted. Most of the south uses this farming method, which allows you to harvest two crops of grain a year. In the north, wheat is planted in the spring and harvested in the summer, and Chinese cabbage can be planted next, and other food crops cannot be matured.

Winter wheat and spring wheat are reported to be two varieties of wheat, but there are some differences. Winter wheat is cold-tolerant, generally harvested in June, distributed south of the Great Wall, with a harvest of 200 450 kg per mu; Spring wheat is drought-resistant, harvested in autumn, distributed in the north of the Yangtze River, with a yield of 300 500 kg per mu; The differences are very noticeable and reflect the characteristics of each well.

1. Different growth habits. Winter wheat has strong cold resistance, seedlings can survive in cold winters, grow faster when spring comes, and the ground powder is delicious; Spring wheat is highly drought resistant. It has a short plant type, large panicles, and a short growth cycle, which is suitable for spring sowing, but the taste is not as good as winter wheat.

2. The distribution area is different. Winter wheat is mainly grown in the north, and if it is planted in the south, not only will the survival rate be low, but the yield will also decrease. However, spring wheat is widely distributed in the south, and if spring wheat is grown in the north, the survival rate is also extremely low.

3. Different planting areas. Due to their different habits, the planting area is also different. In general, the Great Wall is the dividing line. Winter wheat grows south of the Great Wall and has a warm and pleasant climate, while spring wheat grows north of the Great Wall, where temperatures are generally cooler.

4. Different outputs. Although they are both wheat, they are still very different, from planting to harvesting to yielding. Winter wheat can be harvested 200 450 kg per mu, and spring wheat can be harvested 300 500 kg per mu.

In this regard, spring wheat has an advantage.

5. The planting climate is different. Spring wheat is planted in cold places in winter. Because the winter is too cold to sow seeds, they are sown after the beginning of spring. It is known as spring wheat. Winter wheat is grown in warm places. It is sown in the winter and harvested in the summer.

6. The harvest time is different. Spring wheat matures in August and September each year, so a great deal of harvest and marketing begins during these two months. Winter wheat is harvested in April and May each year.

Planting precautions: Spring wheat is mainly planted in the north of the Great Wall, and winter wheat is mainly planted in the south of the Great Wall. Winter wheat in the North China Plain is generally sown in early October and has a growth period of about 230 days.

It turns green in the spring of the following year and ripens in late May to early June of the following year. Winter wheat needs winter, so the latitude can't be too high, otherwise it will freeze to death. There is a local proverb:

The white dew is early, and the cold dew is late. The autumnal equinox is when wheat is planted. "For example, wheat in Australia is also sown in the fall and harvested in the summer.

The wheat in the Northeast Plain is spring wheat, which is sown in the spring (mid-April). Spring wheat is sensitive to light and has a short growth period, mostly around 90 days. Harvested in the summer (around July 20).

If the wheat grows taller, then it is spring wheat, and if it is smaller, then it is winter wheat.

There is also a difference in the timing of planting of winter wheat and spring wheat, with winter wheat generally sown in the autumn of each year and harvested in the spring of the following year, and spring wheat being sown in the spring of each year. Winter wheat is mainly distributed in North China, and spring wheat is mainly distributed in Northeast China.

Winter wheat has strong cold resistance during the growth process, and the seedlings can overwinter. Spring wheat has strong drought resistance, short plants and large ears, and a short growth period, which is suitable for spring sowing, but it is not as delicious as winter wheat.

1. The planting time is different, and the harvest time is different. Spring wheat is harvested in the month sown after the Spring Festival, mainly north of the Great Wall. Winter wheat is sown in one month and harvested the following year, mainly south of the Great Wall.

2. The planting place is different: spring wheat is planted in a very cold place in winter, because the winter is too cold to be sown, so it is planted after the beginning of spring, called spring wheat, winter wheat is planted in a slightly warmer place, sown in winter and harvested in summer, for example, spring wheat in Northeast China, winter wheat in North China and its south.

3. Different planting areas: Chinese wheat is mainly planted in the northern region, and the northeast region has a cold and long winter, so wheat is planted only after the temperature rises in spring. The temperature in North China is slightly higher in winter, and wheat can survive the winter, so wheat is planted in winter.

The differences between spring wheat and winter wheat are: different sowing and harvesting time, different resistance and different local climate.

1. The sowing and harvesting time is different

Spring wheat is harvested in the month after the Spring Festival, when it is sown and is mainly distributed north of the Great Wall. Winter wheat: It refers to the sowing in the month and harvesting in the following month, mainly distributed in the south of the Great Wall.

2. The resistance is different

Spring wheat has a strong drought resistance, short plants and large ears, and a short growth period, which is suitable for spring sowing, but it is not as delicious as winter wheat flour. Winter wheat in the growth process of the ability to resist the cold is very strong, its seedlings can survive the winter, in the spring comes, the seedlings differentiate quickly, grow up one by one, winter wheat milled flour is delicious.

3. The climate of the planting place is different, and the rent is high

Spring wheat is planted in a very cold place in winter, because the winter is too cold to be sown, so it is planted after the beginning of spring, which is called spring wheat; Winter wheat is planted in slightly warmer places, sown in winter and harvested in summer, for example, spring wheat in northeast China, and winter wheat in North China and its south.

Precautions for planting:

The north of the Great Wall is mainly planted with spring wheat, the south of the Great Wall is mainly planted with winter wheat, the sowing period of winter wheat in the North China Plain is generally in early October, the growth period is about 230 days, the spring is green, mature in late May to early June of the second year, winter wheat is to overwinter, so the latitude can not be too high, otherwise it will freeze to death, there is a local proverb: "white dew early, cold dew late, autumn equinox wheat planting is the right time." ”

For example, wheat in Australia is also sown in autumn and harvested in summer, while wheat in the Northeast Plains is spring wheat and sown in spring (mid-April), spring wheat is sensitive to light, and the growth period is short, mostly about 90 days, and harvested in summer (around July 20).
