Can we still grow wheat in heavy snow and solar terms?
During the solar term of heavy snow, wheat can no longer be planted, and wheat can not emerge, only rotten seeds can be formed. The arrival of heavy snow and solar terms indicates that the weather is getting colder and colder, the earth is frozen, and seedlings will not emerge from the soil. Therefore, we should sow in time in winter, so as not to delay the farming season and cause losses.
The temperature at which wheat grows
The growth and development of wheat have different suitable temperature ranges at different stages. At the optimum temperature, it grows fastest and develops best. The optimum temperature required in different stages is different. The optimum temperature for wheat seed germination and emergence is15-20℃; The optimum temperature of wheat root growth is 16-20℃, and the lowest temperature is 2℃, which will be inhibited if it exceeds 30℃.
Temperature is an important factor affecting the tillering growth of wheat. At 2-4℃, tillers began to grow, and the optimum temperature was 13- 18℃, which slowed down tiller growth. Generally speaking, wheat stalks begin to elongate above 10℃ and form short and thick stalks at 12- 16℃. When the temperature is above 20℃, they tend to grow white, the stems are weak and prone to lodging. The suitable temperature for wheat grain filling is 20-22℃. If there are many dry and hot winds and the daily average temperature is higher than 25℃, the filling process will be shortened and the grain weight will be reduced due to the rapid water loss.
