Vegetable seedlings pay attention to many

Sub-seedlings of vegetables can prevent the seedlings from squeezing seedlings, expand the nutrition and light area of ​​seedlings, and promote the growth of seedlings. However, split seedlings will inevitably cause different degrees of root-cutting, reduce root function, and inhibit the normal growth of seedlings. To ensure that the seedlings restore as much as possible the root absorption function, the healthy growth of seedlings, we must understand what the stress in the separation process.

Time for seedlings to be timely

General cold bed nursery. Split seedlings start from 2 true leaves and should be controlled at 3 to 4 true leaves. Because the seedlings are relatively small, the seedling rate is high, if the seedling age is too large, it will affect the flower bud differentiation, and each time the seedlings are divided, they will be delayed for 5 to 6 days. 3 to 5 days before seedling separation, the seedbed should be cooled, ventilation should be increased, water must be controlled, and seedlings must be trained. Dividing the seedlings when they do to dig seedlings, while arranging a small arch shed seedlings cover film, to prevent the high temperature at noon so that seedlings wilt. When seedlings are divided, they are required to concentrate labor and time for row seedlings in order to facilitate the robust growth and management of seedlings. Separate seedlings should be taken once.

The seedling density should be suitable

There is a close relationship between seedling density and yield. Within a certain density range, with the increase of the seedling distance, the previous period of production will be relatively increased, and the efficiency will also be greatly increased. In general, when the pepper is divided into seedlings, the seedling distance is 7~8 cm, and when the eggplant is divided into seedlings, the seedling spacing is 8~9 cm. If the seedbed is not tense, the seedling distance can be 8 to 10 cm; the diameter of the nutrition seedling nursery is 8 to 10 cm, and the earth is filled with earthworms to improve the moisturizing and heat preservation effect, which is conducive to cultivating the strong seedlings and increasing the yield.

Segregation method should be scientific

Half-days before seedlings, the nursery should be watered to facilitate the digging of seedlings and seedlings. Use shovels or shovels to dig seedlings. Digging seedlings requires 1 to 2 cm from the seedling root. After digging the seedlings, most of the soil in the root zone should be gently removed by hand, and then the seedlings should be placed in pots or baskets to facilitate row seedlings. Do not injure the seedlings and protect the cotyledons carefully.

Immediately after the seedlings are excavated, the seedlings should be rowed, and in particular, the roots should be protected from the sun or be blown away by the wind. When separating the seedlings, it is best to separate the seedlings from the seedlings, remove diseased seedlings, insect-injured seedlings, and headless seedlings.

After sub-seedling should be shallow row, generally 1 to 2 cm in the cotyledon unearthed as the standard, rows of seedlings should be tightly rooted soil, and timely pouring enough root water. The seedlings excavated on the day were lined up. If you can't finish in the morning, you can concentrate on soil and cover it with a cover to prevent seedlings from losing water and wilting, and finish it in the afternoon.
