What is the suitable sowing temperature for wheat?
The specific temperature varies slightly due to different varieties. Winter varieties require air temperature 16- 18 degrees and ground temperature 17- 19 degrees; Semi-winter varieties require air temperature 14- 16 degrees and ground temperature 15- 17 degrees; Spring varieties require air temperature 12- 14 degrees and ground temperature 13- 15 degrees.
Generally speaking, the suitable temperature for wheat seed germination and emergence is 15-20 degrees, the suitable temperature for root growth is 16-20 degrees, and the lowest temperature is 2 degrees. More than 30 degrees will be suppressed.
At the same time, in the process of planting, we should use humus soil with deep soil layer and good air permeability, and sow wheat, and then sow the seeds in the soil. After wheat germinates, nitrogen fertilizer or farmyard manure can be provided to make seedlings grow sturdily.
Requirements of Sowing Wheat on Soil
Wheat is suitable for growing in soil with deep soil layer, good structure and deep plough layer, which is beneficial to water storage and fertilizer conservation and better root system development.
1, soil compactness, pH value and salt content
Moderate soil tightness is beneficial to the growth of wheat roots. It is best not to use sand or clay. The pH value of the soil planted in it needs to be maintained between 6 and 7, which is close to neutrality. If it exceeds this range, dead seedlings will appear.
2. fertile soil
Wheat is suitable for planting in fertile soil, mainly because it contains sufficient nutrients, so it can be fertilized in a small amount in the later stage, and its growth rate will be accelerated, which is conducive to its bumper harvest and increase yield.
