How to give vegetable seedlings

To divide the seedlings of vegetables, it is necessary to prevent the seedlings from squeezing seedlings, expand the nutrition and light area of ​​the seedlings, and promote the seedlings to grow faster. However, split seedlings will inevitably cause different degrees of root-cutting, reduce root function, and inhibit the normal growth of seedlings. To ensure that seedlings restore as much as possible the root absorption function, the healthy growth of seedlings, the technical points are as follows:

Sub-seedlings are normally planted in cold beds. Pepper, eggplant seedlings take about 40 to 60 days. Split seedlings start from 2 true leaves, and seedlings should be controlled within 3 to 4 true leaves. Because the seedlings are relatively small, the seedling rate is high and the seedling age is too large, affecting flower bud differentiation, and each time the seedlings are divided, they are 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 edge digging seedlings, while arranging a small arch shed seedlings cover film, to prevent noon high temperature seedlings wilting. 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.

Density suitable for seedling density is closely related to yield. Within a certain range, with the increase in the distance from the seedlings, the yield in the previous period will be relatively increased, and the benefits will also increase substantially. The general pepper seedlings are 7 to 8 cm apart and eggplants are 8 to 9 cm. If the seedbed is not tense, the seedling distance can reach 8~10 cm; the diameter of the nutrition seedling nursery is 8~10 cm, and the earth is filled with earthworms to improve the moisturizing and heat preservation effect, which is beneficial for cultivating strong seedlings and improving the yield and benefit.

Sub-seedling methods should be watered on the seedbed in the first half of the seedlings, and it is advantageous to dig seedlings and seedlings with soil. Use shovels or shovels to dig seedlings. Digging seedlings requires 1 to 2 cm from the seedling root. After excavating the seedlings, gently excavate most of the soil from the root and then place it in a basin or basket for drainage. Do not injure the shoots and take care of the cotyledons.

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.

The seedlings should be in shallow rows, and the cotyledons usually have 1 to 2 cm unearthed as the standard. Row seedlings should be tightly rooted and the roots should be poured in time. 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 dehydration and wilting, and finish it in the afternoon.
