Asparagus is the seedling of asparagus, a herb. This plant is called white bamboo shoot when it is not unearthed, and it will turn green after it is unearthed, so it is called green bamboo shoot. Even if the planting areas and varieties are different, as long as they are exposed to sunlight, they will turn green, and those buried in the soil will remain white because they are blocked from sunlight. At the same time, it is also a common vegetable in our life. Asparagus, a vegetable, is rich in nutrients and trace elements, and contains many nutrients needed by human growth. It is a vegetable with high nutritional value. Moreover, there are more and more asparagus growers, and the price of asparagus in the market is getting more and more expensive, so many people want to plant asparagus. But planting asparagus requires certain conditions. Today we are going to talk about what kind of environment is needed for planting asparagus.
First of all, the demand for land
The roots of this plant are very developed, and the roots extend far-reaching. Therefore, before planting, we should choose the soil with rich nutrition, loose and deep soil, and relatively breathable land. However, the land should not be too alkaline. If it is too alkaline, the roots may not develop normally and shrink, and the plants on the ground will be affected and die slowly. Although this plant has a good adaptability to the acidity and alkalinity of the land, it is still necessary to control the ph value of the land at around 6.5. This is the most suitable soil for growth.
The second point is sunlight
First of all, this plant likes sunlight very much when it grows, so it has a great demand for sunlight and can adapt to strong light and long-term irradiation. If there is insufficient sunshine, the growth of asparagus will be hindered, which will lead to small branches and leaves, and it seems that there is no nutrition. But the light changes with the weather, so it is also closely related to the temperature. When the temperature is too high, the sunshine may be more abundant, but this is not conducive to their growth. If the temperature is too low, there may be insufficient sunlight, which will lead to their slow growth and reduce their output.
The third point is the requirement for water.
This plant has a very good ability to preserve water, and the water evaporates very little. This is because their roots have a very good water absorption ability, so it is a very drought-tolerant plant. But at the time of harvest, there must be no shortage of water, and the land must be kept moist at all times. If there is a lack of water, plants may become weak, and the buds that have just grown underground may die. But this plant is not a very waterlogging-tolerant plant, and if there is too much water, it may also lead to root rot. Therefore, we should also do a good job in water management when planting. We must not let too much water accumulate or be too dry, which will affect growth.
The fourth point is the requirement for temperature.
This requirement is not very high, because asparagus has a good adaptability to temperature, and can withstand cold and high temperature, and can be planted in many areas. But it is most suitable for growing in areas with obvious four seasons. In the weather of MINUS 33 degrees, when the frozen soil reaches one meter thick, this plant can still spend the winter safely. Although the yield is reduced, the quality will not change. The temperature of seed germination is 5℃, and the most suitable temperature is 25℃ to 35℃. If the temperature is higher than 3℃, their germination trend will obviously decrease. If it is propagated by seeds, it can grow continuously for more than ten years. When it is particularly cold, all the parts on the ground wither and the roots sleep underground. But dormancy is not common in warm areas.
