Wheat is a cool crop, and the climate in the north is cold, why is wheat still used as the main food

First of all, there is no such thing as coolness and heat in plants, I only know what cold-tolerant, heat-resistant, drought-tolerant and so on.

Then, let's talk about why wheat is the main food in the north.

First, the climate in the north determines the cultivation of wheat.

The growth and development process of crops is adapted to the seasonal changes in temperature. Some crops are sown in the fall, grow with some nutrients before winter, survive the cold winter, and re-emerge vigorously the following spring (think of the plant hibernating), flowering and bearing fruit in late spring and early summer. But if this autumn-sown crop is planted in the spring and is not subjected to the test of winter, the consequence is that it will not bloom or will be delayed.

This low-temperature induction of flowering in plants is called vernalization. Wheat is divided into winter wheat and spring wheat, winter wheat is sown in autumn, and it needs to undergo vernalization to make it bloom normally in the next spring, and then bear fruit; And spring wheat is not needed, spring sowing will do. The climate in the north is actually quite suitable for growing wheat, wheat is not afraid of cold, but it needs the cold winter in the north to make it thrive, which is determined by the characteristics of plants.

You may be misconcepting about cool crops, but wheat is actually hardy. According to the different requirements for temperature, it is divided into two physiological types: winter wheat and spring wheat, and different types are planted in different regions. Spring wheat was planted in Heilongjiang, Inner Mongolia and Northwest China, sown in March and April in spring, matured in July and August, and had a short growth period of about 100 days. Winter wheat is planted in eastern Liaoning, North China, southern Xinjiang, Shaanxi, provinces in the Yangtze River basin and South China, sown in October and November in autumn, matures in May and June of the following year, and the growth period is about 180 days.

Second, it is impossible to grow rice due to the lack of water in the north.

Of course, wheat needs a certain amount of low temperature vernalization to promote tillering and ear formation, and the north is just the first winter temperature, so the north is dominated by wheat.

In the northern region of China, the main food crops are wheat, corn, millet, etc

So the answer is: corn; Millet

Nongsan Hu Yuanmin has a saying; Ripe wheat on a cold day, meaning; Wheat as a wintering crop, severe cold and low temperature does not affect the wintering of wheat, before the beginning of winter to water a wintering water, for the root of wheat, moisture is very important, first of all, you are not like a real rural farmer, the real farmer is aware of the growth of wheat. Tell you about it! This year's weather was a bit abnormal, but it didn't affect the wheat.

Wheat is afraid of cold before and after the year, and at this time it is not afraid of cold at all. The roots are thick, the leather rod is hard to punch, Xiaoman has been in the past few days, Xiaoman is full of grains, and it has rained a little to medium rain here in Henan, alas! The farmers are very happy, I don't know how much things have been saved, we here (Lubei) May 1st and 2nd frost is very bad, remember that there is a year around April 20 is also frost to do branches very bad, wheat flowering grains are not harvested, no flowering yield.

I don't know what will happen this year, and no one knows until the food is in hand.

During the wheat flowering period, the temperature is low and there are many rainy days, which has a great impact on wheat flour, and the wheat yield will not be too high this year based on experience. The Year of the Ox and Horse, good farming, good harvest is a year, God's eyes are bright, farmers are bitter, farmers are difficult, God has to take care of it. Now we have already planted winter wheat here, and the wheat seedlings have been produced.

Regarding what the subject said, the weather is not too cold now, and what will be the impact of wheat planting too early, Wei Nong talks about his own views, and everyone is together.

It is also the most suitable temperature at about 16 degrees, if the temperature has been higher than 20 degrees, it is better not to sow for the time being, the temperature is slightly higher, if the soil moisture is good, the emergence of wheat is fast, and it is easy to lead to vigorous growth. In general, the average daily temperature is 14 18 o'clock, which is the best sowing date for winter wheat. Among them, the temperature of winter wheat varieties was 16 18 was the best sowing date, and the temperature of semi-winter wheat varieties was 14 16 was the best sowing date.

It will still affect the growth of wheat, because wheat also has certain requirements for the temperature of things, and too low or enviable temperature will only cause wheat to be frostbitten, and it will also cause wheat yield to be reduced.

It will hinder the differentiation of the spikelets, and will also reduce the number of panicle grains, and will also greatly reduce the yield. Many of today's wheat hailstorms are frost-resistant varieties, so in general, they will not have any effect on wheat.

The impact is more serious, for example, it will lead to lower and lower wheat yields, and it will affect the planting environment of wheat, and it will also affect the normal growth of wheat, and it will lead to the grain is not full, and there is no way to fill the grain normally, and the number of wheat ears will also be reduced, and the number of grains in the ears will also be reduced.

There is a saying among peasants; Ripe wheat on a cold day, meaning; Wheat as a winter food crop, cold and low temperature does not harm the more sleepy winter of wheat, the weather is a little abnormal, but there is no harm to the wheat Lingqi.

Wheat is afraid of cold before the year after the year, and at this time Hou is not afraid of cold at all. The fibrous roots are thick, the leather rod is hard, Xiaoman has been a few days in the past, Xiaoman is the seed is round, and it has rained a small to heavy rain here in Henan before, alas! The farmers are very happy, I don't know how much I have saved, everyone here (Lubei) May 1st and 2nd frost is very bad, I still remember that there is a year around April 20 is also frost is very bad, wheat flowering is nothing, no flowering yield.

It is not clear what will happen in 2021, and no one knows until the food crops are harvested.

During the wheat flowering period, the temperature is low and there are many rainy days, which is particularly harmful to wheat pollination, and with work experience, wheat production in 2021 is not easy to be too high. The Year of the Sheep and the Ox, good farming, harvesting a good year is a year, the eyes of God are bright, the farmers are bitter, the farmers are difficult, God has to take care of it. Now the winter wheat harvest has already been completed, and the wheat seedlings have already been produced.

In response to what the subject often said, the weather is not too cold recently, and what are the adverse effects of wheat planting too early, Wei Nong talked about his own views, and everyone discussed it together.

16 degrees is also more suitable temperature, if the temperature has been higher than 20 degrees, or do not need to plant for the time being, the temperature is slightly higher, if coupled with the soil layer of seedlings is good, wheat germination is fast, it is very easy to cause yellow leaf disease. Under normal circumstances, the average daily temperature is 14 18 o'clock, which is the best sowing date for winter wheat. Among them, the temperature of winter wheat varieties was 16 ft volts18 was the best sowing date, and the temperature of semi-winter wheat varieties was 14 16 was the best sowing date.

The influencing factors for planting winter wheat in the south and spring wheat in the north are: temperature.

The Northeast is cold, and wheat cannot overwinter, so only spring wheat can be grown. In North China, spring wheat can only be planted because of the high temperature in summer, which leads to only flowering and no fruiting, so winter wheat can only be planted.

Winter wheat is generally sown around the autumn equinox, and after a cold winter, it flowers and bears fruit the following year, and is planted in North China. Spring wheat is sown in the spring and harvested in the fall. Winter wheat is sown in late autumn and early winter and harvested in summer.

The ripening system is three crops in two years or one crop a year, and the planting area is the northeast region.

Growing conditions:The average daily temperature of winter varieties was 16 18, semi-winter was 14 16, and spring was 12 14. The temperature of the sky is affected by the geographical latitude and altitude, that is, the higher the latitude and altitude, the lower the temperature, and the earlier the sowing date.

Planting Techniques:In order to have a high yield of wheat, it is necessary to continuously improve soil fertility in planting, solve the living soil layer, make the fertility and depth of the cultivated layer fine, permeable and flat, and also integrate water, fertilizer, gas and heat. The roots of wheat were mainly distributed in the soil layer of 0 50 cm. Under shallow tillage, the main root system is distributed in the soil layer of 0 15 cm or 20 cm.

At the same time, all kinds of nutrients needed by wheat can be found in the soil, but not in sufficient quantities. Therefore, it should be supplemented by external fertilization.

Humidity is a problem for the dry winter in the south, drought tolerant wheat so it is planted in winter, and the opposite is true in the north.

Not refers to the Contract Personal Protective Suites.

In the northern wheat area, the spring warming is fast, the differentiation period of wheat panicle is short, it is difficult to form an ear, the temperature is high in the later stage of grain filling, there are more dry and hot wind, bacterial wilt and diseases and pests after the rain, the dry grain weight is unstable, and the success possibility of relying on large spikes and large grains to create high yield is small. High yield should mainly rely on striving for sufficient panicle number, and choose the appropriate sowing date, and the formation of strong seedlings before winter is the basis for increasing the panicle rate in the future. So plant wheat in the fall.

The most suitable temperature for wheat seed germination is 20 to 30 degrees Celsius, although the fastest germination in this temperature range, but because of the strong respiration of the forest beat, the material consumption is large, the roots and shoots are not robust, and the roots and buds are required to grow long and strong in production, so the suitable temperature for wheat sowing is lower than the most suitable temperature for germination in Hengchun, and the average daily temperature is 15 to 18 degrees Celsius in the northern winter wheat area, which is suitable for its growth.

Wheat is a common food crop, is a wide range of cereal crops, its temperature-loving, planting is suitable for the use of compound fertilizer, it is suitable for the use of phosphorus and potassium fertilizer, can be used more containing these elements of compound fertilizer. Wheat has many uses, it can be used to make bread, steamed buns, biscuits, noodles and other foods, and it also has medicinal properties, which can nourish the mind and calm the nerves.

Is wheat a food crop.

Wheat is a grain, it belongs to a common food crop, it does not belong to the cash crop, it is a very widely planted cereal crop, there are many jujube feasts, generally can be used to make bread, steamed buns, biscuits, noodles and other foods.

Wheat is a kind of crop, but also a plant of the genus Poaceae, generally has medicinal value, medicine can nourish the mind and calm the nerves, remove annoyance, and can also effectively prevent and treat breast cancer.

What kind of crop is wheat?

Wheat is a food crop among crops, and it can be grown at two times, one from September to October, and the other from March to April.

Wheat does not belong to chlorine-resistant crops, it has a certain chlorine tolerance, and generally wheat is suitable for planting in many places, such as Beijing, Tianjin, Hebei, Henan, Shanxi, etc., which is the main crop in these places.

Small such as Si wheat belongs to crops, it is more temperature-loving, generally planted wheat is more suitable for the use of compound fertilizer, it prefers to contain phosphorus and potassium fertilizer, so you can use more compound fertilizer containing these elements.

If you want to increase the yield of wheat, you must choose high-quality varieties, and also do a good job in water and fertilizer management, to ensure sufficient light conditions, appropriate spraying of some nutrient solutions, but also to do a good job in the prevention and control of pests and diseases.

Be sure to pay attention to frequent ventilation, then clean up stagnant water, choose high-quality wheat, do not let the sun shine, and then reasonably repel pests and weeds on time.
