Matters needing attention in the determination of Maize seedlings

In the seedling stage of maize, the seedling and fixed seedling have certain benefits to its later growth, but the intermediate seedling and fixed seedling should grasp the opportunity, and the seedling can not play a corresponding role if it is too late. Next, with the editor, let's take a look at the seedlings of corn and the matters needing attention.

1. Timely early seedling and fixed seedling

Maize seedlings are generally carried out in the 3-4 leaf stage, when the nutrients carried by maize grains are basically depleted. If the seedlings are too crowded, the roots of the seedlings crisscross each other, there will be serious competition for water and fertilizer, and the leaves overlap and crowd each other. This will not only affect photosynthesis, but also lead to a reduction in yield during seedling growth due to lack of nutrition. In addition, for the fields with poor soil moisture and serious insect pests, the seedlings and fixed seedlings can be appropriately delayed, so that you can die and lack seedlings, but it should not exceed the 6-leaf stage at the latest, which will affect the poor development of individual root system of the plant. it's also extremely disadvantageous to seedling growth. Therefore, suitable time seedlings can not only crowding seedlings and shading each other, saving soil nutrients and water, but also conducive to the cultivation of strong seedlings.

2. According to the choice of seedling stage

Intermediate seedlings and fixed seedlings are not carried out casually, and it is necessary to grasp the principle of "getting rid of the weak and staying strong, keeping sparse, and keeping evenly and strong". For dwarf seedlings, dense leaf seedlings, thin and complete seedlings, damaged by diseases and insect pests and miscellaneous seedlings with obvious differences, they have been removed in time to avoid unnecessary waste. Select the strong seedlings with uniform size, uniform plant, flat stem base and no diseases and insect pests to ensure the quality of the seedlings.

3. Pay attention to the weather

The determination of seedlings should be carried out in the afternoon on a sunny day, because after the harm of diseases and insect pests and poor growth of seedlings, after the sun at noon, it is very easy to appear wilting phenomenon in the afternoon, so it is easy to be eliminated. In a word, scientific interseedling and fixed seedling for maize can not only reduce labor and labor intensity, but also promote the growth and development of maize and achieve the purpose of increasing production and income.

4. Attention density

The density of inter-seedling should be guaranteed. For lack of holes and ridges, seedlings can be kept in adjacent holes (rows) appropriately, but the two seedlings should be of the same size as far as possible, and it is also the same when fixing seedlings. Too dense planting is not conducive to the growth of corn, and it will cause canopy in the field in the later stage. this is extremely disadvantageous to the increase of yield.

The above is the introduction of the matters needing attention in the determination of corn seedlings. I hope I can help you. If you want to know more about it, please follow us.
