The latest course on planting management techniques of fennel

Fennel is no stranger to us, it is relatively common in our life, also known as cumin, can also be used in medicine and cosmetics, cumin or advanced spices and health products, a wide range of use, market demand, so the planting prospect is excellent. Although there are many people planting now, the yield is not very ideal, so how can fennel be planted and managed to achieve high yield? Come and have a look with the editor.

1. Land selection and fertilization

Fennel likes wet and cool environment, and its seeds are relatively small, so its ability to break soil is relatively poor, so it is necessary to choose sandy loam with flat terrain, deep soil layer, loose and fertile soil and strong drainage capacity when planting. Fertilizing should be carried out at the same time after selecting the land, the rotten organic fertilizer or farm manure can be sprinkled on the soil, and then the soil can be ploughed deeply, and in order to reduce the harm of diseases and insect pests in the planting process of fennel, weeding and disinfection work needs to be carried out. you can sprinkle some disinfectants on the soil.

2. Preparation for sowing

When planting, the improved seeds should be prepared first, and the seeds with full grains, yellow-green color, disease-free and no damage should be selected. In order to improve the germination rate and reduce the harm of diseases and insect pests, the seeds can be treated well before sowing. You can choose a sunny day before sowing, expose the seeds for 1-2 days, pay attention to turning the seeds in the sun, make them heated evenly, soak the seeds in salt water, take out the floating seeds, and then mix the seeds with chemicals to eliminate the germs on the surface. mixing seeds with zinc fertilizer before sowing is conducive to the neat emergence of seedlings.

3. Sowing management

Fennel likes cool climate, so sowing can be carried out when the soil temperature is below 5 degrees, and the most suitable time for sowing is in the middle of March every year. The sowing method is also divided into two kinds, one is strip sowing, the other is hole sowing, the density should be controlled when sowing, the best distance for each plant is 15 cm, and the depth is about 5 cm. The general choice is hole sowing, because it saves seeds, while strip sowing requires time and time after emergence.

4. Field management

After seedling emergence, weeding should be carried out in time, weeds should be eliminated in time, and early emergence of seedlings should be promoted. Generally, 2-3 times of weeding and weeding are needed in seedling stage, and the depth of each tillage should be deepened. When the seedlings grow 3-4 true leaves, set the seedlings in time, control the distance between plants at about 5 cm, and do a good job in fertilizer and water management at the same time. Fennel is a plant that likes drought and is afraid of humidity, so we should pay special attention to water, especially after rain, high humidity, it is very easy to cause a large number of plant death. So watering generally choose to water in the evening or cloudy days, do not water before the rain, timely drainage after the rain. Topdressing is generally required for 2-3 times during the whole growing period. The first time before flowering, mainly nitrogen fertilizer; once in the filling period, mainly phosphorus and potassium fertilizer; the last time before harvest, boron fertilizer and calcium fertilizer should be sprayed to improve yield and quality.
