Causes and solutions of uneven emergence of vegetables

Because of the special situation this year, many friends are trapped at home. Friends in the city may be upset that they have no vegetables to eat at home, but for rural friends, there is no such problem. Even if there is no can be planted immediately, but many friends encounter the problem of uneven emergence in the process of planting, so what is the cause of uneven emergence of vegetables? How to solve it? Come and have a look with the editor.

1. Low seed quality

When sowing, the maturity of seeds is different and the old and new seeds are mixed, these factors will lead to uneven emergence of seeds, and the uneven emergence caused by poor seed quality will generally show sparse seedling growth on the seedling bed.

Solution: seed quality should be well mastered through seed testing, and seeds of poor quality, such as seeds with low purity, low germination rate and serious diseases and insect pests, should be firmly avoided, but seeds of high quality and in line with national standards should be selected. only in this way can we ensure that the seedlings are strong and even.

2. Improper seed handling.

Seeds in soaking seeds before germination due to lack of water absorption, or in the process of germination water, temperature, oxygen and other conditions are in line with the standard, will lead to uneven emergence.

Solution: seed germination should meet the needs of water, temperature and oxygen, first of all, seeds must absorb enough water, keep the temperature between 20-30 degrees in the process of germination, and turn every 4-5 hours to increase oxygen content. rinse with warm water once a day, the medicament is the treatment should grasp the appropriate concentration and soaking time.

3. Improper sowing

Uneven sowing, uneven bed, different thickness of soil cover, different environment of seedling bed and other factors will unearth vegetable seedlings unevenly, which is generally realized that some areas of the seedling bed emerge late, while other areas become normal.

Solution: before sowing, water must be poured thoroughly to improve the ground temperature of the seedbed, and warm water can also be watered. Sowing must be uniform, and a layer of fine soil should be covered after sowing. The thickness of the covered soil should be uniform, and the diameter of the general seed should be 3-5 times. From sowing to emergence. It is required that the nursery bed has sufficient moisture, good air permeability and suitable temperature.

4. Unearthed with a hat

The so-called cap unearthed, that is, after the seed germination, failed to leave the seed coat in the soil, the seedlings will push the seed coat out of the soil, the seed coat tightly attached to the cotyledons, so that the cotyledons can not be developed in time, so that not only the emergence of seedlings is uneven, but also affect the photosynthesis of seedlings, which is extremely disadvantageous to the growth of seedlings.

Solution: after sowing, plastic film should be covered to preserve soil moisture to prevent the bed soil from being too dry. once cracks appear in the bed soil, it should be filled with moist fine soil in time, and at the same time, the wettability of the soil layer should be increased appropriately to help cotyledon shelling.

The above is the introduction of the causes and solutions of uneven emergence of vegetables. I hope I can help you. If you want to know more about it, please follow us.
