Planting techniques of asparagus

1. Select land and sow seeds

Asparagus planting must choose deep and fertile soil, before planting to loosen the soil, fertilize. Then choose the most suitable local asparagus seed to sow on the whole plot, after finishing the field, first come out a small ditch, the ditch is about 4 centimeters deep, and then sow the seeds in the ditch, be more uniform, wait until the seeds are sown, cover it with a thin soil of about 2 centimeters, then pour the right amount of water on the top of the ditch, and finally cover the plastic film on it, or cover it with withered grass fertilizer.

two。 Weeding between seedlings

After the seedlings are unearthed, the weeds that occur between the seedlings should be pulled out in time before they grow up, and when weeds occur, they should be pulled out at any time. After the emergence of the seedlings, the seedlings should be removed, and the weak seedlings should be transplanted alone, or directly removed. Combined with pulling grass, you can loosen the soil with sticks between rows, which is beneficial to growth. When the seedlings grow to a height of about 10 centimeters, it is necessary to start the second seedling. The fast-growing seedlings can be first transplanted into the field, leaving the rest to continue to grow. Every time the seedlings need to be watered to avoid root damage.

3. Fertilizer and water

After the seeds are unearthed, they should be watered and moisturized every day. Then when the growth reaches 2 to 4 cm, the manure of human and animal diluted with water is applied, and calcium superphosphate and potassium nitrate fertilizer can be applied appropriately.

4. Pest control

In the process of planting asparagus, we should pay attention to control the invasion of aphids, vegetable leaf insects, moths and other pests, and spray pesticides in advance to do a good job of control.

When the branches of the seedlings are almost ready for harvest, they will be harvested every 4-5 days after that.
