Soil problems: Long-term unreasonable watering, fertilization and frequent use of herbicides have caused soil compaction, acidification, and salinity. These problems will inevitably affect the normal growth of wheat roots. If the root system does not grow well, the wheat will not eat well, which will cause abnormal phenomena such as yellowing of wheat plants and leaves. Returning straw to the field: Due to uneven crushing of straw and huge amount of straw, when wheat is sown, the seeds are sown on the straw. After the seeds take root and germinate, they do not have close contact with the soil. After emergence, the seedlings appear weak, yellow, and grow abnormally. This situation is generally expressed as a row, one by one, and a large amount of straw is exposed on the surface of the soil. Herbicide residues: overuse of post-emergence herbicide (nicosulfuron-methyl) and wild wheat herbicide (disulfuron-methyl), respray (including drift in windy weather), non-compliance with technical rules, etc. The weak and yellow seedlings caused by soil residue and plant phytotoxicity can cause seedling shortage and broken ridges in serious cases. Fertilizer damage to burning seedlings: unscientific fertilization or use of farm manure without decomposing causes weak yellowing of seedlings caused by burning seeds, and then spraying ammonium bicarbonate or slow-dissolving chemical fertilizers when watering after seedlings, which are more granular or powdery , Staying on the leaves for a long time causes the burning of the seedlings to cause the yellow leaf dry tip phenomenon. Weather: After the emergence of wheat, it is affected by weather conditions such as cold and hot, large temperature difference between day and night, causing freezing damage, and yellowing and chlorosis of leaves will occur. Reasons for watering: after the emergence of wheat, watering too early or watering frequently, resulting in too slow water penetration, long-term soaking of wheat seedlings in water, flooding seedlings yellowing, or long-term soaking of soil in water to form salinization, which is not good for normal wheat Growth, causing the wheat shoots to turn yellow. Sowing technology: Sowing too early or too late, too large or too small, etc. will easily lead to yellow leaves in wheat seedlings.
