1. When planters deep-seek sowing, the soil gap is relatively large, which leads to adverse effects on wheat root growth.
2. In the seedling stage, the wheat itself is relatively weak in resistance and therefore vulnerable to freezing damage. It should be known that although the wheat has a relatively high freezing tolerance after entering the middle of tillering, it can withstand the cold weather of minus 7 to 10 degrees, but in the seedling stage before tillering, if the temperature is between minus 5 degrees and minus 6 degrees.

1. Covering the river mud: If there are conditions, you can pour the mud in the river, and pour the mud on the wheat seedlings. There is a lot of organic matter on the mud, and after the mud sticks to the wheat, it is good for cold resistance and heat damage.
2. Appropriately take the wheat pressure wheat: You can use the tractor to power the tractor. Install two pressure rollers with diameters close to the tire diameter on the left and right wheels of the walking tractor to press the wheat. Prevent the effects of freezing damage.
The above is the reason why the wheat in the small series explains the phenomenon of less white roots and more yellow roots, and the remedial measures.
