When is the wheat sown in October?

Wheat sowing time is1October 8 to1October 23.

In most wheat-growing areas, from the perspective of climatic conditions and wheat growth characteristics, sowing from1October 8 to1October 23, that is, after the National Day to the first first frost solar term, is the most suitable period for planting wheat. During this period, the temperature and ground temperature decreased, which was beneficial to the growth and maturity of wheat.

Sowing wheat in this period of time will make the root system of wheat stronger, and the ability of cold resistance and frost resistance will be stronger. But some farmers often sow immediately after the autumn harvest, which is equivalent to sowing wheat in advance, which is not desirable. Although sowing by grabbing soil moisture can improve the emergence rate of wheat, because of sowing in advance, the temperature of wheat at seedling stage is higher, the growth rate is faster, it is easy to grow too vigorously before winter, and its cold resistance is weak, so it is easy to suffer from freezing injury.

Wheat growing environment

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℃, that of semi-winter varieties is 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.
