The seeds are selected one time before sowing, and the flat and large grains are removed, and the seed size is made as uniform as possible.
The spring wind is big and easy to run, and it is necessary to grasp the appropriate seeding depth according to the lyrics. If the temperature is too low, soil compaction, etc., it is not easy to emerge. If the drought is too shallow and the moisture is poor, the seeds will not be able to absorb water. Generally, the sowing depth is 3 to 5 cm, the sandy soil is slightly deep, and the clay soil is slightly shallow.
Check the quality of the seeding at the beginning of the seeding. The main contents of the inspection are as follows: First, whether the planting depth is consistent, second, whether it is broadcast to the dry soil layer, and third, whether there is a broken strip. If these problems exist, it is necessary to communicate with the tractor hand in time to find the cause and correct it in time.
After sowing, it is necessary to suppress it in time. The soil is too imaginary. First, it is serious, and second, it can cause weak seedlings.
If there is a lack of seedlings after emergence, it is not advisable to replenish the seedlings. If conditions permit, you can also move the seedlings. When moving the seedlings, pay attention to the clods as large as possible. After the transplanting is successful, remove the leaves from the ground to prevent excessive evaporation and increase the survival rate.
Pay attention to the distance between the species and the fertilizer. Try to adjust the spacing between seeds and fertilizers to avoid fat burning.
Pay attention to the choice of the seeder. The quality of the planter directly affects the quality of the sowing of corn. Generally speaking, the new planter has high technical content and good seeding quality.
