How can corn cultivation be managed and produced? These five points must be noted!
As one of the main food crops in China, corn is not low in total output, especially in the northern grain growing countries. What we are going to learn today is how to increase the yield of corn from the details. Let's take a look at it. 1. Seed buying skills First of all, don't listen to what kind of output is high on the Internet. You can buy it. In fact, the variety must meet the local planting conditions. Then the farmer's shop that chooses to buy the seeds must be a regular shop. Don't spread it. There are problems and people can't be found. 2. Seeding management skills Before seeding, corn seeds must be seeded first, in order to prevent pests and diseases and increase yield. The depth of sowing should not be too deep. According to the specific conditions in the soil, under normal conditions, the depth of 3-5cm can be. If the field is a little dry, the sowing depth can be appropriately increased to 5-7cm, but not less than 3cm. Seeding density should also be appropriate, not too dense or too thin. 3. Water and fertilizer management Corn is a high-yield crop. The demand for water and fertilizer is very large during the growth process. According to the correct practice, soil fertilization is required, but in the actual process, everyone will not be so precise. The base fertilizer is ternary compound fertilizer with NPK. During the trumpet period, the fertilizer is applied with urea, and the foliar fertilizer of trace elements in the middle and late stages is sprayed. 4. Weeding matters Closed herbicides cannot be used after the emergence of corn. Generally, when the corn is planted, it will be sprayed within seven days. If it is to weed after the emergence of corn, it is recommended to use it in the 3-5 leaf stage of corn. Whether it is using nicosulfuron or mesotrione, it can be sprayed in the whole field. However, once the corn has passed the 5-leaf stage, it can no longer be used. The whole field is sprayed. If you want to use herbicides, be sure to use a herbicide containing a safener, and a directional spray is recommended. 5. Pest control Common diseases of corn include large and small spot disease, head smut, rust, rough disease, stem-based rot, etc., and diseases are generally recommended to prevent in advance. Pest pests such as armyworms, mites, gray planthoppers, thrips, etc., which are common in the above-ground parts of corn, should be controlled in time after the occurrence of the field, and select suitable insecticides according to different pests, such as avidin, imidacloprid, Vermicillin and some pyrethroid insecticides. The above is the technical point of corn planting. In these aspects, everyone can pay more attention in the process of planting corn.
