At present, the wheat harvest in Henan, the largest wheat province, has exceeded 90%. Good varieties, good methods and good years have brought a bumper harvest to Henan. This year, the performance of high-quality wheat is eye-catching, not only the area has increased to 6.5438+0.2 million mu, but also the output has increased a lot.

The Ministry of Agriculture and Rural Affairs reminded that with the opening of the wheat harvest curtain in North China, the tough battle of machine-harvested wheat has entered the sprint stage in the second half of the year. All localities should make good use of the weather, pay close attention to the harvest and sow autumn grain in time while ensuring that the summer grain particles are returned to the warehouse.

In Henan, a major wheat-growing province, a new wheat variety with strong gluten and high quality has created a large-area yield record.

The market demand for strong gluten and high quality wheat is good, but it has been plagued by the contradiction between high quality, low yield and poor quality. The new variety Fengde Cunmai No.5, which set a record for high yield, has solved this problem, and its quality has reached the national first-class standard of high quality and strong gluten, which is suitable for popularization and planting in the main wheat producing areas such as Henan, Anhui and Jiangsu in the south of Huanghuai.

This year, Henan Province organized 465,438+10,000 sets of agricultural machinery in the third summer to ensure that the yield per unit area of wheat machinery is stable at over 98% and the sowing amount of corn machinery is stable at over 90%. At the same time, strive to reach a new level in the comprehensive utilization of wheat straw and flower sowing.

According to the statistics of the Provincial Agricultural Machinery Bureau, as of yesterday 17, the whole province has harvested 80.56 million mu of wheat, accounting for 93% of the sown area, with a machine yield of 99%. On the same day, 80,000 harvesters were put into use, and the daily harvest of wheat was 48 1 10,000 mu.

Wheat is the general name of wheat, and its representative species is common wheat (scientific name: Triticum aestivum L.), which is a cereal crop widely planted all over the world. Wheat caryopsis is one of the staple foods of human beings. After grinding into flour, it can be made into bread, steamed bread, biscuits, noodles and other foods, and after fermentation, it can be made into beer, alcohol, white wine (such as vodka) or biomass fuel.

Wheat is one of the three major cereals, almost all of which can be eaten, and only about one-sixth of which is used as feed. The two river basins are the earliest areas for growing wheat in the world, and China is one of the earliest countries for growing wheat in the world.

Deep soil layer, good structure and deep tillage layer are beneficial to water storage and fertilizer conservation and promote root system development. Soil structure refers to the proportion of solid (organic and inorganic), liquid and gas, which is closely related to soil moisture, air, temperature and nutrients. For example, sandy soil and heavy clay have poor structure and are difficult to form high yield.

The average daily temperature of winter varieties is 16 ~ 18℃, semi-winter varieties are 14 ~ 16℃, and the elasticity is 12 ~ 14℃. Temperature and air are affected by geographical latitude and altitude, that is, the higher latitude and altitude, the lower temperature and the earlier sowing date.

Wheat crops with long sunshine time (8 to 12 hours per day), if the sunshine conditions are insufficient. Can't pass the light stage, can't knot, can't bear fruit. The photoperiod of wheat is after vernalization.
