The following editor brings you the field management technology of Angelica dahurica. Let's have a look!

1. The seedlings are fixed

Angelica dahurica It is not suitable for the seedlings to break the soil in that year, and when the seedlings return to green in the second spring, the seedlings should start to grow to about 6 cm, based on the principle of staying strong and getting weak, and the seedlings should be interspersed again every 1 month or so. Then fix the seedlings when the seedlings grow to 15 cm high in mid-April, and control the distance between the seedlings at about 14 cm. If it is hole sowing, then no more than 3 plants should be left in each hole. To improve the permeability of the field, when determining the seedlings, we should pay attention to pulling out the prosperous seedlings to prevent early bolting.

2. Ploughing and weeding

Weeding in ploughing is also very important to the growth of Angelica dahurica. as I just said, Angelica dahurica seedlings grow slowly and have weak ability, if they are not weeded in time. Weeds will snatch the necessary nutrients for the growth of seedlings and seriously affect the growth of seedlings. Mid-tillage can not only effectively weed, but also prevent soil consolidation, affect the infiltration of water and fertilizer, and prevent root nutrient water absorption from being blocked. When setting seedlings, weeding can be carried out together with ploughing and weeding. When Angelica dahurica seedlings grow up and close ridges, their growth ability and nutrient absorption capacity become stronger, the weeding work can be stopped.

3. topdressing at the right time

Angelica dahurica To prevent seedlings from flourishing due to excessive nutrition and early bolting. Angelica dahurica Then it was carried out once after the seedling was fixed and before the ridge was closed.

Attention should be paid to the times and dosage when topdressing, depending on soil fertility and plant growth.

4. Rational watering

Angelica dahurica This can improve the emergence rate, keep the soil moist in the seedling stage, and prevent the seedlings from lack of water, such as yellow leaves and other bad phenomena. Then it is necessary to pour enough antifreeze water before winter to improve the cold resistance of the seedlings and prevent frost damage. It should be properly watered with topdressing in the spring of the following year, and adequate moisture should be ensured in dog days. But we should also pay attention to the amount, not too much, to prevent stagnant water leading to root waterlogging, retting roots and other phenomena, so we should also pay attention to drainage work.

The above is a brief introduction to the main points of field management of Angelica dahurica. The management of Angelica dahurica is very important to its growth. The quality of management is directly related to the growth ability, yield and quality of Angelica dahurica. Therefore, when planting, we must do a good job in field management.
