Southern wheat harvest time

Winter wheat is generally mature and harvested from late June to early July of the following year; spring wheat is generally mature and harvested from mid-July to late August. Wheat is harvested earlier in the south than in the north, and the farther north it is, the later the harvest will be.

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.

II. Wheat producing areas in China

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, Xinjiang, Gansu and Inner Mongolia.

There are mainly two kinds of wheat: spring wheat and winter wheat. The flour from winter wheat is more delicious than spring wheat and is often more popular. Wheat is rich in protein, carbohydrates and other substances, which is one of the main food crops in the south and north.
