When will the wheat mature?

Wheat is a kind of commodity grain with rich nutrition and high economic value. it is an annual or biennial herb of Gramineae, which is rich in starch, more protein and a small amount of fat, as well as a variety of mineral elements and vitamin B. but many people do not know when the wheat will mature, so let's take a look at when the wheat will mature.

When will the wheat mature?

According to the sowing time, wheat is divided into winter wheat and spring wheat, mainly winter wheat in China. Winter wheat has a strong ability to resist cold in the process of growth, and its seedlings can survive the winter. when spring comes, the seedlings divide iniquity very quickly, squat and grow up, and the flour produced by winter wheat is very delicious. It is usually planted in warmer places, sowing in winter and summer harvest. For example, the northeast of China is spring wheat, and the north and south of China are winter wheat. Spring wheat is planted in cold places in winter, because it is too cold to sow in winter, so it is only planted after the beginning of spring. It has strong drought resistance, large dwarf spikes and short growth period, so it is suitable for sowing in spring, but it is not as delicious as winter wheat flour.

When will the wheat be sown?

The optimum sowing time for all wheat varieties is 10: 12 days, and the best sowing time is 5: 7 days. The optimum sowing temperature for winter varieties in southern Shandong is 20: 16 ℃. From September 25 to October 10, the optimum sowing temperature is 16: 18 ℃. From September 27 to October 5, the optimum sowing temperature for semi-winter varieties is 18: 16 ℃, and from September 27 to October 12, the optimum sowing temperature is 16: 17 ℃. The suitable sowing temperature for spring varieties is 16: 14 ℃, and the optimum sowing temperature is 16: 15 ℃ from October 8 to 20, about October 10 to 15. It should be noted that due to the popularization and application of semi-winter varieties, the improvement of soil and fertilizer conditions and the strict control of pre-winter population in cultivation, the sowing date is later than traditional, "White Dew is earlier, Cold Dew is later. The Autumn Equinox planting wheat at that time" is only suitable for shady sloping land in mountainous area, part of saline-alkali land and wheat area in northwest Shandong.

What are the producing areas of wheat in our country?

1. Northern winter wheat area: Fangdong wheat area is mainly distributed in Qinling Mountains, north of Huaihe River and south of the Great Wall, where winter wheat output accounts for about 56% of the country's total wheat output, which is mainly distributed in Henan, Hebei, Shandong, Shaanxi and Shanxi provinces.

2. Southern winter wheat area: the southern winter wheat area is mainly distributed to the south of the Huaihe River in the Qinling Mountains, which is the main rice producing area in China. Planting winter wheat is beneficial to increase the multiple cropping index and grain yield, which is characterized by high commodity rate. the main producing areas are concentrated in Jiangsu, Sichuan, Anhui and Hubei provinces.

3. Spring wheat area: the spring wheat area is mainly distributed to the north of the Great Wall, where the temperature is generally low and the production season is short, so it is mainly one crop a year, and the main producing provinces are Heilongjiang, Gansu and Inner Mongolia.

What are the nutritional values of wheat?

1. Wheat is rich in protein, which can maintain potassium and sodium balance, eliminate edema, improve immunity, lower blood pressure, buffer anemia, and is conducive to growth and development.

2. Wheat is rich in phosphorus, which can make up bones and teeth, promote growth and repair of body tissues and organs, supply energy and vitality, and participate in the regulation of acid-base balance.

3. Wheat is rich in copper, which is an indispensable micronutrient for human health, which has an important effect on the development and function of blood, central nervous system and immune system, hair, skin and bone tissue, brain, liver and heart.

4. Wheat is rich in carbohydrates, which are necessary to maintain brain function, regulate fat metabolism, provide dietary fiber, save protein, detoxify and enhance intestinal function.

What are the storage methods of wheat?

1, heat storage: wheat in the midsummer sunny, high temperature weather, the wheat temperature will be about 50oC, lasting more than two hours, moisture dropped to less than 12.5%, gathered around 3 o'clock in the afternoon, while hot into the warehouse, bulk pile capping, the whole warehouse closed, so that the grain temperature lasts above 40oC for about 10 days, all undead pests die in the sun, according to the situation, can continue to be airtight, or can be turned into ventilation.

2. Low temperature freezing: when the winter temperature is low, the barn is turned, impurity removed and frozen, the wheat temperature is reduced to about 0 ℃, and then closed while the cold is used, which has a good effect on eliminating the overwintering pests in the wheat pile, but the low temperature airtight wheat pile should strictly guard against the contact of warm air flow to avoid condensation on the surface of the wheat pile.

3. Natural anoxia: wheat harvest is at high temperature, and some dryness and precipitation is less than 12.5%. The characteristics of high grain temperature and vigorous physiological activity in the post-ripening period can be used to seal the film to achieve the natural anoxic state of the wheat pile, so as to restrain the harm of pests. For aged wheat every other year, methods such as auxiliary oxygen reduction or filling with carbon dioxide or nitrogen can be used to control insect pests.
