1, land selection and soil preparation
Asparagus is not tolerant to waterlogging. When planting, you should choose a field with high terrain and convenient drainage, apply decomposed farmyard manure to the field, and then plough it once with a rotary tiller to ensure soft and fertile soil and make asparagus seeds germinate better.
2. Soak the seeds
Asparagus has a hard shell, so you must soak the seeds first to accelerate germination. Generally, it takes 7 to 15 to sprout, so friends who plant it must be patient and change water for it every day. The higher the temperature, the faster the germination. ?
3. Raise seedlings
When asparagus seeds germinate, they should be raised in a seedling bowl or paper cup. The soil for raising seedlings can be professional seedling soil or fine sandy soil. First, water is poured on the soil once, and then sowing is carried out. Generally, it takes about 5 days to emerge. At this time, it is necessary to take it to the sun immediately after emergence to prevent the formation of tall seedlings.
4. Sowing method
Before planting asparagus seeds, soak them in water, then take them out and wrap them with wet cloth to accelerate germination. When asparagus sprouts, spread the seeds on the soil surface and cover them with fine soil and film.
5. Transplanting
Asparagus can be transplanted when it grows to almost 10 cm. Because asparagus will grow for more than ten years, more organic fertilizer should be applied before transplanting. The suggested method is to dig a deep ditch first, apply the fermented organic fertilizer, then cover it with soil, and then transplant it on the soil, so as to ensure that the seedlings will not be burned in the early stage.
6. Management
The management after transplanting is much simpler, basically just weeding and watering. The bamboo shoots of asparagus in the same year are very thin, and the yield in the next year is relatively low and thin. At this time, root cultivation is the main method. Don't pick the first few asparagus, and wait until the fourth one. In the third year, it will enter the high-yield period, and then asparagus can be harvested continuously.
