In the middle and late August, the time for planting the vegetables in the autumnal period was relatively long, and at this time, the weather was more rainy, which was not conducive to planting seedlings. However, when I was interviewed in the countryside, I discovered that some vegetable farmers did not plant in the rainy season; others also planted on rainy days, thinking that the seedlings were quick.
In this regard, I think it is very inappropriate. The reason is as follows:
In the rainy weather, the planting of vegetables, although the vegetables after the planting appear to be healthy, and the seedlings are not slow, but after the rainy weather turns fine, the high temperature and strong light will easily cause the acute wilting of the seedlings and serious dehydration. Because of the rainy weather, the environmental conditions of high humidity, high humidity, and low light in the greenhouse not only weaken the transpiration of the seedlings, but also the moisture in the air can basically meet the growth requirements of the seedlings, stems and leaves, and thus are not conducive to the growth of the root system, or even rooting. Only rooting. After the weather turned fine, the humidity in the greenhouse decreased, and the transpiration of the plants increased rapidly. The water absorbed by the plants could not meet the needs of transpiration. Therefore, the plants would inevitably suffer from wilting and severe dehydration and death.
Therefore, we advocate that vegetables should be planted in good weather and at least 2-3 days of fine weather must be guaranteed after planting.
Although 2-3 days after planting, the seedlings will experience slight wilting, but the wilting is self-regulation of the seedlings, which not only reduces the evaporation of water in the plants, but also promotes the growth of the roots; Usually 4-6 leaves when planting), more conducive to slow seedlings. After 2-3 days, with the emergence of new roots, the plants entered a normal growth state without acute wilting.
Note: If the seedlings are ordered from the nursery factory, when the seedlings are delivered on rainy days or the weather forecast is expected on the 2nd and 3rd days of rain, planting is not recommended but should be managed centrally until the weather turns fine.
In addition, when transplanting seedlings, they must be transplanted in stages so as to facilitate tidy seedlings and facilitate management.
According to the classification of large, medium, and small scales, the seedlings are transported to the side of the planting ridge. From the perspective of the entire shed, the big seedlings should be placed at the east and the west and the front of the greenhouse. The seedlings should be placed in the middle of the greenhouse. Judging from one line, the big seedlings are in the front, the young seedlings are in the back, and the general seedlings are in the middle, which is favorable for later growth and neatness.
Because the lighting in the shed is strong before and after, the seedlings and seedlings must be grasped before the cultivars are dense and thin, so that the seedlings in different parts can obtain similar light. Planting can be carried out according to the distance between the planting points and planting seedlings in the hole; or in the planting ridges, a deep ditch can be established and the seedlings can be placed in the ditch in accordance with the prescribed spacing of the plants.
