Planting time, method and technology of fennel in spring

Fennel can be planted in two seasons, in March and April in spring and September in autumn. Although it can be planted in winter, it needs to be planted in greenhouse because the outdoor temperature is too low, and the yield is not very high. Therefore, it is suggested to sow in February-May in spring or July-September in summer.

The germination of fennel is relatively simple, and there is no need for complicated soaking and accelerating germination before sowing. Everyone can sow after buying seeds and preparing the soil.

3. Soil preparation and fertilization

Fennel is usually sown on a flat bed. First, prepare the soil, apply sole fertilizer to make the sole wet, then turn over the ground and rake it flat, make a flat bed with a width of 1.5m, dry drill, furrow with a spacing of 30cm, sow evenly, sow thinly, and do not replant fennel, so the sowing amount should be appropriate, and sow 8~ 10 kg per mu. After sowing, cover the soil and level it with an iron rake, which can not only preserve moisture, but also make the seeds better combined with the soil, which is beneficial to seedling emergence.

4. Emergency management

Fennel can emerge in about three or four days after sowing. After emergence, topdressing can be applied 1-2 times until harvest. When it grows to about 10cm, it can be topdressing once, which can not only provide sufficient nutrients, but also prevent the plant from growing too fast and affect the quality and yield. In daily management, don't have too much water, just look at the dryness and wetness.

5, pest control

The main pest of fennel is root rot, which will cause losses or crop failure in severe cases. When sick plants are found, they should be left in the field to avoid infecting other plants. Pests have always been ground tigers. Spray special pesticides in time after discovery. When choosing fields, they should choose fields without eggs or kill insects first.

Step 6 harvest

Fennel can be harvested when it grows to more than 30 cm. Fennel can be harvested many times or in a large area at one time. If you want to increase the yield, you can take the method of harvesting many times, and each time you pick or harvest, you should leave the ground more than three centimeters. Topdressing after harvest can promote the secondary growth rate. If you harvest once, the harvest is done by uprooting.
