Wheat sowing time should be decided according to the region.The areas south of the Great Wall mainly grow winter wheat, which is usually sown between September and October each year and harvested between April and May the following year.The area north of the Great Wall mainly grows spring wheat, which is usually sown between March and April after the Spring Festival, and can be harvested from August to September of that year.
Winter wheat planted south of the Great Wall can be harvested from April to May of the following year if it is sown between September and October.If the spring wheat planted north of the Great Wall is sown after the Spring Festival, it can be harvested from August to September of that year.
There are three main sowing methods of wheat: drill sowing, broadcast sowing and hole sowing.The seeds of drilling fall more evenly, and the depth of covering soil is more consistent.After the emergence of seedlings, seedlings will be more competitive.Later, it will be found that the ventilation and permeability of wheat with drilling method are better, which is convenient for mechanized management.
Broadcast sowing method is mainly used in wheat-cotton intercropping or rice-wheat rotation areas, where the soil is sticky and difficult to prepare, so it is suitable for sowing with broadcast sowing method, which can save time and labor.This kind of sowing way produces the seedling single plant nutrition area to be good, but the seed enters the soil the depth to be inconsistent.
Dibble seeding is also called dibble seeding or nest seeding, which is used in rice stubble wheat fields.This kind of sowing method is more centralized in fertilization, the seeds are sown in the same depth, and the emergence of seedlings is more competitive, which is conducive to management.The disadvantage is that it is time-consuming, the hole distance is large, and the number of seedlings and ears is small, which will affect the final yield.
