Before the corn is planted, the seeds should be selected once, and the flat and large grains should be removed, and the seed size should be made as uniform as possible.

The spring wind is big and easy to run, and it is necessary to grasp the appropriate planting depth of corn 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 depth of sowing is 3 to 5 cm, the sandy soil can be slightly deep, and the clay soil can be slightly shallow.

The quality of the seeding should be checked. The main contents of the inspection are whether the seeding depth is consistent, and whether the seeding depth is on the dry soil layer. The third is 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, not only preventing the soil from being too sham, causing serious running, but also preventing the occurrence of slings and weak seedlings.

If there is a lack of seedlings after emergence, it is not advisable to use seedlings. It is best to use 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 of water.

Pay attention to the distance between the species and the fertilizer. At present, most of the corn is planted with mechanical sowing. The fertilizer applied at the time of sowing is spread in a very narrow ditch. Although the applied fertilizer has a distance from the corn seed, the concentration of the fertilizer applied is very concentrated. If you don't pay attention, you will see the phenomenon of burning. Therefore, when planting spring corn, try to adjust the spacing between seeds and fertilizers to avoid hypertrophy.

Pay attention to the choice of planter. 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.

What problems should we pay attention to when using solar energy for power supply?
1. The whole day sunshine time of monitoring points along the expressway shall be considered first. As the main energy of the power supply system comes from sunlight, the sunshine exposure time must be considered, which is particularly prominent in mountainous areas where there is little sunshine, but not in plain areas.
2. Working power, working voltage and current of monitoring facilities along the expressway. After considering the power of the whole load, we can choose the solar panel that is more suitable for the long-term operation of the equipment.
3. If the battery discharge cannot make the monitoring equipment work for a long time, the monitoring system will be paralyzed in the rainy season, but the expressway is prone to accidents in the rainy season.
4. The conversion rate of solar cells is low. At present, the conversion rate of solar cell power supply is only about 20%, that is to say, if the silicon solar cell is spread over a square meter, 100~200W of power can be obtained, which is obviously not enough to meet the long-term operation of the monitoring equipment. Of course, with the development of technology and the improvement of the quality of crystalline silicon cells, we can obtain more power resources in a smaller area in the near future.
