Field management technology of fennel

Fennel is a kind of herb of Umbelliferae, which is distributed all over China. The tender leaves of fennel can not only be eaten as a vegetable, but also a commonly used seasoning. Fruit also has medicinal value, has a variety of medicinal effects, such as expelling wind and expectoration, dispelling cold and relieving pain, which is welcomed by many people. So how to manage when growing fennel? The following editor brings you the field management technology of fennel, let's have a look!

1. Ploughing and weeding

First of all, we need to do a good job of weeding in the field, the proper removal of weeds can improve the permeability of the field and promote the growth of fennel. If weeding is not in time, weeds will not only rob the nutrition needed for the growth of fennel, but also breed a variety of bacteria, cause disease, and seriously affect the growth of fennel. After weeding, burn away from the field to avoid seed residue and cause weeds to grow again. If cultivated in the middle, it can not only achieve the purpose of weeding, but also improve the soil structure, improve the permeability and promote the growth of fennel.

2. Water and fertilizer management

Fennel growth also has a certain demand for nutrient water, so we must do a good job in water and fertilizer work. During the whole growth period of fennel, topdressing should be applied for about 3 times, and the amount of fertilizer applied each time can be increased appropriately. The main fertilizers for each topdressing are farm manure, urea and so on. Then we should pay attention to watering, watering should not be too much, in the rainy season, we should also timely drainage, to avoid stagnant water leading to fennel seedlings rot, reduce production. Therefore, before planting, we should dig ditches to ensure good drainage and irrigation in the field and promote the normal growth of fennel.

3. Observe frequently

When planting fennel, we should often observe the growth of fennel. For some seedlings with weak growth and diseases and insect pests should be pulled out, otherwise it is very easy to lead to the spread of diseases and insect pests, expand the affected area, and affect the growth of healthy seedlings. After pulling out the seedlings, it is necessary to replenish the strong seedlings at the same growth stage in time to maintain the rate of uniform seedlings. For some treatable diseases and insect pests, they should be treated in time. If it loses its therapeutic value, it should be removed in time.

4. Timely harvest

The florescence of fennel is relatively long, so the ripening time of seeds is different. Therefore, we should harvest the fennel according to the actual situation, and cut the first mature inflorescence. Then, after the secondary inflorescence is mature, a comprehensive harvest will be carried out. The harvest time of fennel is generally around September every year, and it should be properly exposed after harvest. Put it in a highly ventilated place to dry in the shade to avoid rain, when the sun is strong, we should also pay attention to timely shading.

The above is a brief introduction of fennel field management technology. The management of fennel planting is very important, which is directly related to the yield, so we must pay more attention to it. That's all for today's introduction.
