How to apply fertilizer to asparagus

The scientific name of asparagus is Yongcai, which is a specialty vegetable of our country and is very popular in our country. Its stems and leaves can be made into different dishes, and now the market demand for asparagus is increasing, and the planting area is also increasing. Fertilization is essential when growing asparagus, so how should we apply fertilizer? The following editor has brought you the fertilization method of asparagus, let's have a look!

1. Growth habits

Asparagus has strong growth ability and can quickly adapt to all kinds of soil, but try to plant it on fertile, soft and fertile soil. After planting, the growth rate of asparagus is very fast, the demand for nutrition is large, there is a strong fertilizer tolerance, the yield and quality will be improved. However, the planting land where seeds are left should be controlled to apply fertilizer, otherwise it will easily lead to the phenomenon of excessive growth of hollow vegetables. The planting base fertilizer is mainly rotten farm manure, and the dosage is controlled and kept at about 700 kg / mu. Reasonable fertilization method can ensure the robust growth and improve the yield and quality of asparagus.

2. The law of fertilizer requirement

Asparagus can be harvested many times in a year, so in addition to applying sufficient base fertilizer before planting, it is also necessary to topdressing in time during the whole growth period to ensure adequate nutrition for the growth of asparagus. In the seedling stage of asparagus, it is necessary to properly spray dilute dung water and control the dosage to prevent fertilizer damage. Then, when the seedlings grow about 3 true leaves, the compound fertilizer is applied in time to promote the growth of the seedlings and enhance the growth ability. It is necessary to apply fertilizer for each harvest in the later stage, and the fertilizer should be fully diluted during topdressing, preferably with watering. Ensure comprehensive and uniform, prevent fertilizer from burning roots.

3. topdressing at the right time

In the early stage of fertilization, attention should be paid to the work of ploughing and weeding, which can not only ensure adequate nutrition, but also improve the temperature and fertilizer preservation of the soil. In the growing period, the growth ability of asparagus is strong, and the requirement of fertilizer and water is high. Therefore, when topdressing, you should also pay attention to proper watering, and when the seedlings grow to 6-9 cm, you can begin to fertilize for the first time. Then fertilizer was applied every 1-2 weeks or so, and nitrogen fertilizer was applied after the first harvest to restore the growth of asparagus as soon as possible. Then fertilizer was applied every 3 weeks to provide adequate nutrition for subsequent new plants.

4. Points for attention

We should clear weeds in the field before fertilizing to prevent weeds and spinach from grabbing fertilizer. And in order to improve the growth ability of asparagus and prevent the incidence of diseases and insect pests, we should strengthen field management when applying fertilizer. In the seedling stage and the middle and late growth stage, Zhuangzhuanling and other chemicals can be properly sprayed to thicken the stems, improve the nutrient transport capacity and enhance the leaves of hollow cabbage. When applying fertilizer, apply chemical fertilizer as little as possible to prevent soil pollution and affect the growth of asparagus.

The above is a brief introduction to the fertilization method of asparagus, in fact, it is also some matters needing attention when applying fertilizer. When applying fertilizer, we should not only ensure adequate nutrition for the growth of asparagus, but also prevent problems such as fertilizer damage caused by improper fertilization, which affect the growth of asparagus.
