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℃, 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.
