There is a skill in dividing vegetable seedlings.

Sub-seedlings are also called inverted seedlings and transferred seedlings. When the distance between vegetable seedlings can no longer meet the needs of continued growth of seedlings, the seedlings should be divided in time. The following points should be paid attention to in the process of dividing seedlings:

1. The time to divide the seedlings should be timely. Generally, the time of seedling division is controlled from 2 true leaves to 3-4 true leaves. If the seedling age is too old, it will affect the flower bud differentiation, and once per minute, the growth will be delayed for 5-6 days. 3-5 days before seedling division, the seedling bed should cool down, control moisture and exercise seedlings. When dividing the seedlings, we should dig the seedlings and cover the seedlings in a small arch shed to prevent the seedlings from wilting in the high temperature at noon. When dividing seedlings, concentrate on labor and time to arrange seedlings as much as possible, so as to facilitate the robust growth and management of seedlings. It is advisable to divide seedlings at one time.

two。 The seedling density should be suitable. In a certain range of density, with the increase of seedling distance, the early yield will be relatively increased. Generally, the seedling spacing of pepper and eggplant is 7-8 cm and 8-9 cm respectively. The diameter of nutrition bowl seedling is mostly 10 cm, which is enriched with soil between bowls to improve the effect of moisturizing and heat preservation, which is beneficial to the cultivation of strong seedlings.

3. The method of dividing seedlings should be scientific. The seedling bed should be watered half a day before seedling division to facilitate the digging of seedlings and the soil of seedling roots. When digging seedlings, use a small shovel, which should be 1-2 cm away from the roots of the seedlings. After digging up the seedlings, gently dig off part of the soil from the root belt with your hands, and then put the seedlings in a basin or basket. Take seedlings not to hurt tender stems, cotyledons should be carefully protected.

4. The method of planting seedlings should be appropriate. Immediately after the seedlings are dug up, the seedlings should be discharged immediately, especially to prevent the roots from being dried by the sun or the wind. When dividing the seedlings, it is best to separate the large and small seedlings and remove the diseased seedlings, insect-injured seedlings and headless seedlings. After sub-seedling shallow planting, generally with cotyledons unearthed 1-2 cm as the standard, to cultivate the root soil tight, and timely pouring enough fixed root water. The seedlings dug on the same day were planted on the same day. If you can't finish planting in the morning, you can gather the seedlings together and surround them with soil and cover them with a cover to prevent the seedlings from losing water and wilting, and finish planting in time in the afternoon.
