How to obtain high yield of wheat? To get high yield of wheat, we must do a good job in wheat winter management. Today, we will talk to you about the high-yield cultivation techniques of winter wheat. Let's learn it!
Li Da Ge, a big wheat grower, planted 25 acres of wheat this year, but Li Da Ge’s wheat problem has been a big problem this year. At first, the wheat was quite neat, and when Li Da Ge finished the wheat, there was a piece of death. seedling.
The planting time and variety of the big brother's wheat and neighbor's family are the same, but the neighboring family's wheat grows neatly, and there is no dead seedling. So what is the cause of Li’s family’s wheat?

1. Fertilizer management before winter wheat can be flexibly controlled according to the condition of the seedlings and lyrics. For wheat with good seedlings and good lyrics, the wheat fields that have been suppressed after sowing may not be watered and topdressed before winter. After the sowing, there is no wheat field under the suppression, the soil is not empty or the quality of the straw is not good. Before the freezing, winter irrigation must be carried out to stabilize the soil, promote the development of wheat packing and big cockroaches, and ensure the safe wintering of the wheat seedlings.
2, lower than the quality of the land preparation or weak seedlings caused by pests and diseases, thin seedlings and lack of fertilizer caused by annoying yellow seedlings, should be watered early, and apply 10 kg of urea per acre or 25-30 kg of ammonium bicarbonate.
