Time is right. The seedlings usually 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 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 should concentrate as much time as possible for labor and time for row seedlings, in order to facilitate seedlings robust growth and management. Separate seedlings should be taken once.
The density should be suitable. 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. The seedlings usually have 7 to 8 cm seedlings, and the eggplant seedlings have 8 to 9 cm seedlings. If the seedbed is not tense, the seedling distance can be increased to 8 to 10 cm. The diameter of the nutrition seedling nursery is 8 to 10 cm. The earth is filled with earthworms to improve the moisturizing and heat preservation effect, which is conducive to the cultivation of strong seedlings.
The method must be scientific. Half-days before seedlings, the nursery should be watered to facilitate the digging of seedlings and seedlings. Use a small shovel to dig seedlings and require 1 to 2 cm away from the seedling root. After digging, gently remove some of the soil from the root zone and then place the seedling in a pot or basket 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. Shallow seedlings after sub-seedling, generally 1 to 2 cm out of the cotyledon unearthed as the standard, should be tightly rooted soil, and timely pouring enough water.
