Field management of asparagus

Asparagus is cultivated all over China, but it is suitable for growing in hot and humid areas, mainly in the Lingnan region of China. It is a kind of vegetable in summer and autumn, but although it is relatively simple to grow asparagus, there are still many cases of planting failures. The main reason is poor management, so how to manage the cultivation of asparagus in the field? The following editor brings you the field management of asparagus planting. Let's have a look!

1. Fertilizer and water management

When asparagus is successfully planted, the demand for fertilizer and water will gradually increase. At this time, we should strengthen fertilizer and water management and topdressing in time. After planting according to the planting area to control the fertilizer, the early topdressing is mainly nitrogen fertilizer, the amount of fertilizer is about 10kg/ mu, fertilizer should not be too much, otherwise it will cause damage to the seedlings and affect the growth. In the growth process of asparagus, it is necessary to keep the soil in a moist state to prevent the symptoms of water shortage. And in the later stage, it is necessary to top fertilize each harvest, so as to prevent the lack of nutrition, hinder the growth and reduce the yield of newborn hollow vegetables.

2. Ploughing and weeding

Intertillage weeding is an important and necessary work in the cultivation of asparagus, because the plant is relatively short, the root system is shallow, and the ability of nutrient absorption is not strong. If there is no timely ploughing and weeding, it will not only affect the nutrition absorption of the roots, but also rob the nutrition of hollow vegetables, resulting in poor hollow growth. Therefore, we should regularly observe the situation in the field and find that the whitening of the border should be ploughed in time, which should not be too deep to prevent damage to the roots. When weeding, we should pay attention to the use of herbicides to avoid inhibiting the growth of asparagus.

3. Control temperature

Spinach is a kind of plant that lives in the tropics, which requires a high temperature and is suitable to live in a high temperature environment. Therefore, in the process of planting, the temperature should be managed well, the temperature during the day should be about 32 degrees, the temperature difference between day and night should not exceed 20 degrees, and the lowest temperature at night should not be less than 12 degrees. Suitable temperature is the key to ensure the healthy growth of asparagus. In order to ensure the growth of asparagus, it is necessary to add heating equipment in the planting greenhouse in the low temperature season and weather.

4. Timely harvest

Asparagus is a sustainable new vegetable, which is usually harvested by pinching. When the asparagus plant grows to about 28 cm, it can be harvested, leaving about 10 cm, and the main harvest part is the upper tender stems and leaves. When the new tip of the axilla is about 20 cm, it can be harvested again, and this harvest should leave about 3 leaves on the plant to promote the occurrence of new shoots and increase the yield. When harvesting, leaves should be left on each harvest branch to restrain the growth of new shoots and prevent premature senescence caused by too much hollow vegetables. Properly cut off the overdense shoots to prevent planting too dense from affecting the growth.

The above is a brief introduction to the field management technology of asparagus. The yield of asparagus is high, the growth period is short, and it is relatively simple to grow. But we still need to have a correct management technology in order to ensure the healthy growth of asparagus, otherwise planting failure is very common. That's all for today's introduction.
