Key points of asparagus cultivation techniques: pay attention to the timing of fertilization

Asparagus is a common food on our home dining tables. As one of the plants in the Asparagaceae family, it has nutrition in many respects. Asparagus can also be called Nandi bamboo shoot or dew bamboo shoot. The finished product we generally eat is green in appearance, and it is often paired with foods such as cured meat and fresh meat. So, are you clear about asparagus cultivation techniques?

Asparagus cultivation techniques

Farmers may be both unfamiliar with and familiar with asparagus. If you are a beginner planting it for the first time, it is inevitable that you will not be clear about the key points. The editor has summarized asparagus cultivation techniques for everyone. Let's take a look:

1. Soil

Before planting green plants, everyone needs to first observe whether the soil is suitable. Asparagus is generally cultivated in sandy loam. Sandy loam is relatively loose, and has good drainage performance and strong air permeability. During the growth process of asparagus, it can play a good protective role and also allow nutrient and water absorption. Asparagus can tolerate slight salinity and alkalinity. When testing salinity and alkalinity, everyone should note that after exceeding 0.2%, asparagus may wither and die.

2. Temperature

Compared with other plants that prefer warm or cold environments, asparagus is easier to grow. Whether in severe cold or intense heat, asparagus has strong adaptability. When the temperature is above 30 degrees, it will slightly affect its germination rate, so when cultivating it, you can choose to sow in spring to avoid high temperatures. In winter, when the temperature is low, the part exposed above the soil may wither, while the fleshy roots in the soil enter dormancy and grow again after safely overwintering.

3. Water

The root system of asparagus is relatively developed, and its tolerance to dry land is good. Generally, during the key period of harvesting spears, everyone needs to water more. Spear harvesting is mostly in dry seasons, and reduced yield will cause the tender stems of asparagus to shrink back, affecting subsequent growth. If the rainy season happens to arrive, also pay attention to testing the soil drainage performance to avoid root rot.

4. Sowing

Asparagus sowing needs to be carried out according to specific requirements based on the state of seed germination and the overall temperature environment. The environment of each region is different, so the specific operations will also differ slightly. According to temperature, we can choose to sow in weather above 10 degrees. Spring is most suitable in the north, while in the south both spring and autumn can be used. When sowing, everyone needs to control the quantity well. If too much is sown, subsequent growth may easily cause the plants to be unable to spread out and affect development. Generally, it is most appropriate to sow at a spacing of 50 cm between rows.

5. Fertilization

Green plants cannot do without fertilizer application. Asparagus is generally fertilized in three periods: seedling, young, and adult. During the seedling period, asparagus is generally given plant ash, poultry and livestock manure, and nutrient soil to supplement energy. Roosters and hens raised by farmers at home are also very good fertilizer, and chicken manure can also be mixed in. In the young period, asparagus can be given nitrogen, phosphorus, and ternary compound fertilizer for application. Well-rotted fertilizer helps growth, and attention should also be paid to turning the soil to maintain its looseness. For adult asparagus, fertilization is generally controlled at about three times per year. In spring, compound fertilizer or organic fertilizer can be added, and this is completed before harvest. In the late harvest period, more compound fertilizer needs to be applied to increase nutrition. Autumn is the peak period for stem growth. In order for asparagus to grow better and faster, potassium fertilizer, phosphorus fertilizer, and nitrogen fertilizer can be used in combination for application.

That is all for today's introduction to asparagus cultivation techniques. Whether stir-fried plainly, stewed in soup, or cooked in a dry pot, asparagus is a delicious and impressive dish. However, everyone must remember to eat less asparagus during allergy periods, so as not to trigger deeper allergic reactions because it is a stimulative food.
