Why wheat seedlings are yellow

Recently, some farmers in Puyang reported that the wheat seedlings on the ground have yellowed. What are the reasons? Through investigation, we found that the main causes of wheat yellow seedlings are the following:

The effect of herbicide residues used in the Shangyu was mainly due to the excessive application of herbicides containing atrazine to the corn field. The herbicide had a long period of persistence and was responsible for damage caused by residues in the soil.

Deep sowing, long stems in the ground, excessive consumption of seed nutrients, less roots, weak seedlings, the yellow leaves were affected by the recent low temperature weather and excessive pesticide residues.

The damage caused by wheat spider mites was not timely prevented, especially if the planting was too deep and the seedlings were relatively weak. The damage was most serious.

To promote the healthy growth of wheat, it is necessary to chase the green manure early. For small seedlings, thin wheat seedlings, and the appearance of yellow seedlings, it is imperative to chase and apply green manure as soon as possible. Per acre topdressing 5 kg of urea, dip in the rain; spray foliar fertilizer and other wheat growth regulators.
