Fennel: Latest Planting Time and Methods Explained in Detail
When planting a crop, we first need to understand its planting time, then understand the environment suitable for its growth, and finally understand its planting methods, so that the crop being planted can be high-yielding. So today, what Qinnong Net wants to tell everyone is how this plant, fennel, is planted, and when the best time to plant it is. Below, join the editor in entering the world of fennel cultivation.
Planting Time
Fennel is a spice, and it is also a food, and it is also a medicinal herb, so its range of uses is still quite wide. Generally, fennel can be planted in two seasons, so the planting times are respectively in March and April in spring, and in September in autumn. Of course, it can also be planted in winter and summer, except that winter requires the use of greenhouse technology, while in summer the yield and quality are not very ideal. Generally speaking, spring sowing is the best sowing time that combines high yield and high quality.
Planting Methods
1. Variety selection
There are many varieties of fennel, but the most common are three: large fennel, small fennel, and bulb fennel. Large fennel mainly has relatively tall plants, relatively high yield, and matures relatively early, making it suitable for planting in China's Inner Mongolia region. Small fennel is relatively shorter than large fennel, and secondly it is more aromatic than large fennel, and it is mainly sown in places such as Beijing in China. Finally, there is bulb fennel; when it grows to a certain extent, its stem gathers and folds into a ball shape, its aroma is very light, but it grows faster than other fennel varieties and its yield is also much higher. Of course, no matter which variety is chosen, the seeds must be selected to be very plump, so that the germination rate, yield, and quality will be at least twice as high.
2. Land selection and land preparation
Fennel actually does not have excessive requirements for soil. Generally, sandy soil with a relatively complete soil layer structure, relatively moderate soil pH, and relatively strong permeability and aeration, as well as strong drainage and irrigation functions, is sufficient. When preparing the land, plow the soil deeply at least 35 cm, then break the soil up a bit finer, try to make the field look relatively level, and fill in places where water collects with soil. Finally, spread about 1,000 jin of organic fertilizer, 50 jin of phosphate fertilizer, and 20 jin of urea per mu on average, and mix in a small amount of potassium fertilizer as base fertilizer. Finally, mix the fertilizers evenly, turn the soil over once more, and then wait for sowing.
3. Sowing and raising seedlings
There are three sowing methods. Before sowing, the seeds need to be soaked for one day, and then subjected to germination treatment. The first sowing method is the simplest, which is broadcast sowing. First, before sowing, water the land once, then evenly scatter the seeds on top, then use a tool to make the seeds sink into the soil, and cover with a layer of dry grass or plastic film. The second method is drilling, that is, on the prepared land, make furrows at a spacing of 15 to 20 cm between each row, with a furrow depth of 3 to 4 cm, then evenly scatter the seeds into the furrows and cover the seeds with soil, then water each furrow once, and finally cover each furrow with a layer of dry grass or film. The last method is hole sowing, which is more troublesome: make a hole every 15 to 20 cm, then scatter seeds into the holes, water and cover with soil, and finally promote seedling emergence.
4. Field management
When the seedlings grow to 4 to 5 cm, in some places the fennel grows relatively densely, while in other places there are only a few sparse plants, so we need to thin the seedlings and fill in gaps. Then during this period there are also many weeds in the field, so one intertillage and weeding should be carried out, and after weeding the first topdressing and watering are needed. On average, 1,000 jin of farmyard manure, 50 jin of potassium fertilizer, and 30 jin of urea need to be applied per mu, and watering 50 grams per plant is sufficient. The second fertilization is when the plants grow to about 10 cm. On average, apply 500 jin of farmyard manure, 100 jin of potassium fertilizer, and 50 jin of boron fertilizer per mu, and at this time a small amount of nitrogen fertilizer can be applied appropriately, and carry out the second watering.
5. Timely harvesting
When the plants grow to about 30 cm, they can be harvested. Fennel can be harvested multiple times or harvested all at once. If a higher yield is desired, it can be harvested in multiple rounds. Each time, cut about 3 to 4 cm above the ground, then apply fertilizer once more to promote growth. If harvesting all at once, simply pull it up by the roots.
