Fennel, a common spice and medicinal herb, is loved for its unique aroma and wide range of uses. How to grow high-yield and high-quality fennel at home? Today, let me reveal the secret for you, grasp the following 5 key points, and easily achieve high-yield and high-quality fennel planting!
1. Choose the right variety
There are many varieties of fennel, which are mainly divided into two categories: anise and cumin. When choosing varieties, we choose them according to the purpose for which they are grown and the local climatic conditions. In general, anise plants are taller and have a relatively higher yield, making them suitable for spices and herbs. Cumin, on the other hand, has a shorter plant but a more intense fragrance, making it suitable for spices and extracting essential oils.
2. Prepare suitable soil
Fennel prefers to grow in loose, fertile, well-drained soil. Before planting, we need to deeply rake the soil and apply well-rotted farmyard manure or compound fertilizer to improve soil fertility. At the same time, in order to ensure the permeability of the soil, we can also add an appropriate amount of river sand or perlite to the soil.
3. Master the correct sowing method
There are two main methods of fennel sowing: direct seeding and seedling transplanting. Live streaming is the sowing of seeds directly into the soil, which is generally suitable for large-scale planting. Seedling transplanting is the process of raising robust seedlings in the seedbed before transplanting them into the field. This method can improve the survival rate of seedlings and is suitable for home planting or small area planting.
When sowing, we should pay attention to the following points: first, the seeds should be selected from the new seeds of the current year to improve the germination rate; Secondly, the sowing depth should be appropriate, generally 2-3 times the diameter of the seed; Finally, after sowing, it is covered with a thin layer of soil or plant ash and then gently compacted.
Fourth, do a good job in field management
Field management is one of the key aspects of fennel cultivation. It mainly includes the following aspects:
Check the seedlings and replant: After the seedlings emerge, we should check the seedlings in time, and find that the lack of seedlings should be replanted in time.
Cultivating and weeding: Fennel needs to be cultivated and weed several times during the growing period. This not only eliminates competition from weeds, but also loosens the soil and improves soil permeability. Generally, weeding is carried out every 10-15 days.
Top dressing watering: During the growth of fennel, we need to top dressing according to the growth of the plant. In general, top application of nitrogen fertilizer is required at seedling and flowering stage, and top application of phosphorus and potassium fertilizer is required at fruiting stage. At the same time, in order to keep the soil moist, we also need to water it regularly. When watering, avoid flooding to avoid soil compaction and plant growth. Drip irrigation or sprinkler irrigation is generally used for watering.
Pest control: The main pests and diseases of fennel are powdery mildew, rust, aphids, etc. In order to control these pests and diseases, we can adopt integrated control measures. Firstly, varieties with strong disease resistance were selected for planting; secondly, strengthen field management to improve the disease resistance of plants; Finally, regular pesticide prevention and treatment is carried out. For example, Bordeaux liquid or carbendazim can be used for spray control in the early stages of the disease.
5. Timely harvesting and storage
Fennel is generally harvested 30-40 days after flowering. Harvesting can take place when the fruit turns yellow-green. Dig carefully during harvest to avoid damaging the plants. After harvesting, the fennel needs to be dried for 2-3 days to reduce the moisture content and then stored. Choose a ventilated and dry place for storage and keep the environment clean and hygienic.
Through the introduction of the above 5 key points, I believe you have a deeper understanding of the planting technology of fennel. As long as you grasp these key technical points and put them into practice, you will definitely be able to achieve high yield and high quality fennel cultivation! 100 Helping Programs
