A detailed explanation of the key technical points of fennel cultivation and management

Fennel is no stranger to everyone; it is quite common in our lives, also known as cumin, and can also be used in medicine and cosmetics. Small fennel is also a high-grade spice and health product, with a wide range of uses and large market demand, so its cultivation prospects are excellent. Although many people grow it now, the yield is not very ideal. So how should fennel be cultivated and managed to achieve high yield? Let's take a look together.

1. Land selection and fertilization

Fennel likes a humid and cool environment, and its seeds are relatively small, so its ability to break through the soil is relatively poor. Therefore, when planting, choose sandy loam soil with flat terrain, deep soil layers, loose and fertile soil, and strong drainage capacity. After selecting the land, fertilization should also be carried out at the same time. Decomposed organic fertilizer or farmyard manure can be spread on the soil, and then the soil should be deeply plowed. To reduce the harm of pests and diseases during fennel cultivation, weeding and disinfection work are needed, and some disinfectant can be spread on the soil.

2. Sowing preparation

Before planting, first prepare good seeds. Choose seeds that are plump, yellow-green in color, disease-free, and undamaged. To increase the germination rate and reduce the harm of pests and diseases, seed treatment can be done before sowing. Before sowing, choose a sunny day and sun-dry the seeds for 1-2 days. When sun-drying the seeds, pay attention to turning them so they are heated evenly. Then soak and select the seeds with salt water, remove the floating seeds, and then dress the seeds with chemicals to eliminate surface pathogens. Before sowing, dress the seeds with zinc fertilizer, which is beneficial for neat emergence.

3. Sowing management

Fennel likes a cool climate, so sowing can be carried out when the soil temperature is below 5 degrees. The most suitable sowing time for it is in mid-March each year. There are also two sowing methods: drilling and hole sowing. When sowing, control the density. The distance between each plant is best controlled at 15 cm, and the depth at about 5 cm. Generally, hole sowing is chosen because it saves more seeds, while drilling requires timely thinning after emergence.

4. Field management

After the seedlings emerge neatly, timely intertillage and weeding should be carried out to remove weeds in time and promote early seedling development. Generally, during the seedling stage, intertillage and weeding are needed 2-3 times, and the depth of each intertillage should be increased. When the seedlings grow 3-4 true leaves, final thinning should be carried out in time, controlling the plant spacing at about 5 cm. At the same time, fertilizer and water management should also be done well. Fennel is a plant that likes drought and fears moisture, so special attention should be paid to water, especially after rain, when humidity is high, which can easily cause large numbers of plants to die. Therefore, watering is generally chosen in the evening or on cloudy days. Do not water before rain, and drain promptly after rain. During the entire growth period, topdressing is generally required 2-3 times. The first time is before flowering, mainly nitrogen fertilizer; one time is during the grain-filling stage, mainly phosphorus and potassium fertilizer; the last time is before harvest, when boron fertilizer and calcium fertilizer should be sprayed to improve yield and quality.
