How to use seedling planting
Seedling is to first place the seeds on the seedbed, seedling pot, plug tray or seedling cup and other seedling cultivation spaces or tools, and then transplant the seedlings to the field when the seedlings grow to a certain size. Although this method requires more work and the seedlings are easily injured (the seedbed requires the least work, the seedlings are the most easily damaged, the seedling pots are the second, and the plugs and seedling cups are the least), but it can eliminate the consumption of seeds and is convenient. Centralized management of seedlings, water control, fertilizer control and heat preservation are all convenient; and facilities can be used to plant seeds earlier, improve the germination rate, and have earlier harvests
It can also reduce the time that the seedlings occupy the field, so that the land can be fully utilized.
Plants not suitable for transplanting
However, not all plants are suitable for transplanting. If the root system of some plants is broken, it is difficult to recover, or it takes a long time to restore normal functions, so it is not suitable for transplanting. Such as corn, beans, etc. On the contrary, lettuce, cabbage, tomato, and dwarf seedbeds require less time to cultivate seedlings, but transplanting melons, etc., is more suitable for transplanting due to the rapid recovery of the root system. In addition, taproot seedlings are easily damaged.
Vegetables, such as white radish grapes, carrots, etc., if the main root is damaged, it is prone to divergent roots, so it is not suitable for transplanting seedlings. In addition, crops with a short growth period, such as cabbage and Artemisia annua, take up a large proportion of the entire growth period of such short-term crops because the seedlings have to wait at least three days to a week after being transplanted. , and transplanting requires more manpower, so it is not calculated.
In addition to the use of seedling trays, a seedbed is a small field specially planned in the field, especially for cultivating seedlings. It is best that the land is relatively fertile, rich in organic matter, has strong water retention and fertility, and is free of pests and diseases; and it is better if it can be closer to the water source, which is convenient for watering, and it is also convenient for building plastic film to keep warm and prevent rain and wind. Seedling pots are generally rectangular shallow plastic pots, and can also be cultivated with various flower pots, pottery pots, shallow pots, fiber cups, seedling cups (smaller flower pots), plug trays (egg-format plastic trays), and even plastic bags.

sowing method
On seedbeds, seedling pots and flower pots, stick the seeds at a certain row spacing, or spread the seeds on them, and then cover with finer soil or medium. Generally, there is no need to produce a large number of seedlings, so the seeds can be planted one by one by hand, and two or three seeds can be planted in each grid, depending on the germination rate of the seeds, and then covered with a fine medium. When the seedlings grow, the weak plants are pulled out, and one seedling is left for each hole. The method of planting seedling cups is the same as that of human hands. Don't plant too many or too close together, or the seedlings will continue to stretch as they compete for living space.
drenching and fertilizing
After sowing, it should be fully watered, but special care should be taken when watering. It is best to use the sprinkler with the weakest water and the weakest water to avoid scattering or washing away the seeds. In the future, check whether you need to spray water every day. It is best to spray a little more each time, but reduce the frequency a little to encourage the root system to grow downward. If the water is frequent, but only the surface is wetted each time, it will encourage the root system to grow on the surface and affect the healthy growth. If the seedling stage is long, it is necessary to fertilize with diluted liquid fertilizer (such as peanut bran water) to reduce the problem of excessive fertilizer concentration and burnt seedlings.
