The main cause of wheat seedling death

1. The quality of straw returned to the field in some plots is poor, and the straw is not fully crushed. In addition, uneven sprinkling results in many places and few places.

塇 2, part of the plot soil after seeding no crackdown or false, seeds can not contact with the soil tightly, wheat seeding, unearthed from the root run wind leakage, killing seedling weak or wheat seeding.

3. Some plots are sown too deep (it is easy to cause sowing too deep if not suppressed before sowing), and the sowing depth reaches 6-10cm. During the emergence of wheat seedlings, excessive nutrients are consumed, resulting in weak seedlings, frost resistance, disease resistance and insect resistance, and death of wheat seedlings.

4, the sudden drop in temperature, at this time the wheat seedlings grow exuberant, tender and juicy leaves, frost resistance is poor, causing freezing damage, the present performance of some leaves dry, death.Deep weak seedling, loose soil 塇 feeding, suppress the false plot death heavier.

5. Some plots have drought, which has poor soil moisture, affecting the growth of wheat seedlings, resulting in yellow and weak seedlings, or even death.

6. During the growth period of the previous corn crop, some plots sprayed the herbicide too late or heavily or sprayed the herbicide too much and at too high concentration, resulting in herbicide residue and pesticide damage, resulting in blackened root system, rot, bent heart leaves and death.

7, spider damage caused wheat seedling leaves white, green, wheat seedling growth is affected.
