When will the latest 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. It is rich in starch, more protein and a small amount of fat, as well as a variety of mineral elements and vitamin B. However, many people do not know when wheat matures. Let's take a look at when wheat matures.

When does the wheat ripen?

Wheat is divided into winter wheat and spring wheat by sowing time, and winter wheat is the main one in China. Winter wheat has a strong ability to resist cold during its growth. Its seedlings can survive the winter. When spring comes, the seedlings quickly divide and grow up. The flour ground by winter wheat is very delicious. It is usually planted in a warmer place. It is sown in winter and harvested in summer. For example, spring wheat is in northeast China, and winter wheat is in north China and its south. Spring wheat is planted in cold winter, because winter is too cold to sow, so it is planted only after spring, drought resistance is extremely strong, short ears, short growth period, suitable for spring sowing, but not as delicious as winter wheat flour.

When is the wheat sown?

The optimum sowing time for winter wheat varieties was 10~12 days, the optimum sowing time was 5~7 days, the optimum sowing temperature for winter wheat varieties was 20~16℃, from September 25 to October 10, the optimum sowing time temperature was 16~18℃, from September 27 to October 5, the optimum sowing time temperature for half winter wheat varieties was 18~16℃, from September 27 to October 12, the optimum sowing time temperature was 16~17℃, The suitable sowing temperature of spring varieties was 16~14℃, from October 8 to 20, and the optimum sowing temperature was 16~15℃, from 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 was delayed compared with the traditional one."White dew is early, cold dew is late, autumn equinox is at the right time to plant wheat" is only suitable for shady slope land in mountainous areas, part of saline land and wheat areas in northwest Shandong Province.

What are our wheat producing areas?

1. Northern winter wheat area: The square winter wheat area is mainly distributed in the north of Qinling Mountain and Huaihe River and south of the Great Wall. The winter wheat output here accounts for about 56% of the total wheat output in China, mainly distributed in Henan, Hebei, Shandong, Shaanxi and Shanxi provinces.

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

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

What nutritional value does wheat have?

1. Wheat is rich in protein, which has the functions of maintaining potassium and sodium balance, eliminating edema, improving immunity, lowering blood pressure, buffering anemia, and facilitating growth and development.

2. Wheat is rich in phosphorus, which can form 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, copper is an indispensable micronutrient for human health, for blood, central nervous system and immune system, hair, skin and bone tissue, as well as brain and liver, heart and other internal organs development and function have an important impact.

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

What are the storage methods for wheat?

1, hot warehouse storage: wheat in midsummer sunny, high temperature weather, the wheat temperature to about 50oC, for more than two hours, moisture to 12.5% below, in the afternoon around 3 o'clock pile, hot into the warehouse, bulk pile cover, the whole warehouse closed, so that the grain temperature above 40oC for about 10 days, the sun did not die all pests died, according to the situation, can continue to be closed, can also be turned to ventilation.

2, low-temperature freezing: the use of winter low temperature, turning, impurity removal, freezing, the wheat temperature to 0℃, and then take advantage of the cold closed, to eliminate the winter pests in the wheat pile, has a good effect, but the low temperature closed wheat pile, to prevent warm air contact, so as not to dew on the surface of the wheat pile.

3, natural hypoxia: wheat harvest is high temperature, if dry timely precipitation to 12.5% below, can use the grain temperature is higher, after the maturity of physiological activity characteristics of film sealing, to achieve the wheat pile natural hypoxia state, thereby inhibiting the harm of pests, for the next year old wheat, can use auxiliary oxygen reduction, or carbon dioxide or nitrogen and other methods to prevent pest storage.

4, dry and sealed: as long as the wheat meets the storage requirements, it can be scattered into the warehouse, capping closed, to prevent moisture absorption and pest breeding, which is particularly effective to inhibit the reproduction of wheat moths, pay attention to insects in the high temperature season, actively ventilate after autumn, uncover the cover to cool down and dissipate moisture, strengthen capping or sealing after spring warm, in order to keep the grain pile low temperature dry and free of insects. In short, only scientific storage and preservation methods can ensure the normal life characteristics of wheat.
