The improper grasp of the distance or density of corn will cause the seedlings to be too dense. In this case, the seedlings should be properly seeded. What kind of corn should be seeded? What are the benefits of corn seedlings? Let me make it for everyone Let me introduce.
Benefits of corn seedlings
1. Corn seedlings can avoid crowding and shading, which is conducive to plant growth and creates good conditions for the growth and development of individual plants.
2. Save limited nutrients and water in the soil. Due to limited available nutrients in the soil. Early seedlings can allow limited available nutrients in the soil to be concentrated and supplied to the retained individual plants.
3. Coordinate plant growth above and below ground. It can coordinate the contradiction between the growth of the ground part of the plant and the growth of the underground part, so that the two promote each other. The root part of the underground part is robust and developed, and the above-ground part of the plant is thick and not overgrown.
4. Reduce the root injury and broken seedling phenomenon during thinning. When the seedlings are thin, the secondary roots are short and easy to pull out, so as not to harm the neighboring seedlings. The seedlings are too late, because the main roots of the seedlings are dense and long, and it is not easy to pull them out. The seedlings are easy to be broken at the same time. At the same time, the neighboring seedlings are pulled out together, which affects the quality of the fixed seedlings and brings difficulties and troubles to future management.
Corn seedling time
During the period of 3 to 4 true leaves of corn, seedlings are fixed on 6-7 true leaves on the basis of 2 strong seedlings per hole. The main benefits are: reducing the damage of corn rough dwarf disease, corn spiralworm and seedling pests to corn seedlings, and increasing the number of seedlings per unit area by 15%.
Corn seedling method
1. Timely seedlings. Thinning seedlings are usually in the 2-leaf and one-heart stage, and fixed seedlings are generally carried out in the 3- to 4-leaf stage, because at this time the nutrients of corn grains have been basically consumed. If the seedlings are crowded, they will compete for fertilizer and water and will affect photosynthesis. Dingmiao late easily lead to reduced production.
2. Pay attention to the weather conditions. Thin seedlings and fixed seedlings should be carried out on a sunny afternoon. Because of disease, insect bites, and poorly growing seedlings, they are prone to wilting after noon sun exposure, which is easy to identify and eliminate.
3. The decision should be made according to the seedling phase. Master the principles of "weak and weak, strong and dense, and even and strong", and choose strong seedlings with the same size, uniform plants, and flat stem base.
4. Guaranteed density. For places with missing holes or broken ridges, you can transplant with soil or leave two plants in adjacent holes (rows) to ensure density.

The decision should be made according to Miao Xiang. Master the principles of "weak and weak, strong and dense, and even and strong", and choose strong seedlings with the same size, uniform plants, and flat stem base.
Guaranteed density. For places with missing holes or broken ridges, you can transplant with soil or leave two plants in adjacent holes (rows) to ensure density.
From this point of view, corn seedlings can not only reduce labor intensity and promote corn growth and development, but also an effective agricultural consumption reduction, production and efficiency measures. Now is the best time for corn seedlings, and I hope that the majority of farmers' friends will carry out in time.
