The latest course of high-yield cultivation techniques of fennel

Cumin, also known as cumin, is a common condiment in our life, not only can be used in medicine and cosmetics, but also advanced spices and health products, widely used and good planting prospects. So how to plant fennel to achieve high yield? Let's take a look at the high-yield cultivation techniques of fennel.

1. Land selection and fertilization

Fennel likes the wet and cool environment, in addition, the seeds of fennel are small, so the ability of breaking soil is poor, and the root system is shallow, so we should choose sandy loam with flat terrain, deep soil layer, loose and fertile soil and good drainage. Reasonable rotation, the previous crop is best when wheat, corn, rice and so on, after selecting a good plot, should be combined with soil preparation for fertilization, generally per mu to apply 3000-4000 kg of mature organic fertilizer or farm fertilizer, as well as 20-30 kg of ternary compound fertilizer, turn it deep into the soil. In order to reduce the harm of diseases and insect pests before planting, weeding and disinfection can be carried out in combination with soil preparation. Acetochlor of lower concentration can be sprayed on the ground, raked fine and mixed evenly with the soil, then leveled or sown for a week.

2. Be ready to sow seeds

First of all, the improved varieties should be selected, and the seeds with full grains, yellow-green color, disease-free and damage-free seeds should be selected. In order to improve the germination rate and reduce the harm of diseases, the seeds should be treated well before sowing. Choose a sunny day before sowing, expose the seeds for one or two days, turn the seeds to make them heated evenly, soak the seeds with 10% salt water, remove those floating on the surface, and select the seeds that sink to the bottom of the water. Then mix the seeds with 0.3% dimethazone to eliminate the bacteria carried on the surface, and generally use zinc fertilizer to mix the seeds before sowing, which is conducive to the neat emergence of fennel seedlings.

3. Sowing seeds

Fennel likes to be cool, so sowing is generally carried out at a ground temperature of about 5 degrees, which is suitable for sowing in the middle of March. Strip sowing and hole sowing can be used to control the row spacing of 15 × 30cm, and the sowing depth is 3-5cm. Generally, strip sowing needs 2-3 kg per mu, while hole sowing needs 1-1.5kg per mu.

4. Field management

After the emergence of fennel seedlings, weeding should be carried out in time to eliminate weeds and promote the early development of seedlings. Generally, weeding should be done for 2-3 times in the seedling stage, and the depth of each tillage should be gradually deepened. When the seedlings grow 3-4 true leaves, the seedlings should be fixed in time, and the plant distance should be controlled at about 5cm, 50-80 000 plants per mu. It is necessary to do a good job in fertilizer and water management in fixed seedlings, fennel is a plant that likes drought and is afraid of wet, so we should pay attention to field water management, especially after rain, the humidity in the field is high, which can easily lead to mass death, so watering is generally chosen in the evening or cloudy days when planting. Do not water before rain, drainage should be timely after rain. Generally, topdressing 2-3 times in the whole growing period, the first time before flowering, applying 5-10 kg of nitrogen fertilizer per mu; the second time from flowering to filling period, generally carrying on leaves and spraying phosphorus and potassium fertilizer; and the third time before harvest, topdressing boron fertilizer and calcium fertilizer can increase yield.

5. Pest control

The main diseases of fennel are root rot, insect pests and grass pests, which will affect the growth and development of fennel and cause yield reduction or no harvest in serious cases. The prevention and control measures of diseases and insect pests should not be underestimated, and the combination of agriculture and chemistry can be used for prevention and control. Seeds and plots without disease and insect pests can be selected and planted. After diseased plants are found, they can be pulled out and burned in the field in time to avoid re-infection and increase the application of phosphorus and potassium fertilizer. improve disease resistance. It is found that diseases and insect pests can be controlled by spraying pesticides.

The above are high-yield cultivation techniques of fennel. I hope it can help you. If you want to know more about vegetable cultivation, please follow us.
