Fennel sowing in March-September.
Fennel like warm and cool, low temperature resistance, heat resistance, suitable for sowing planting in March-September each year, mainly spring and fall sowing, to spring in March and April and fall around September is appropriate.
China's northern and southern regions have different climates, so there is a difference in sowing time, the southern spring sowing in late March, fall sowing in August, while the northern region has low temperatures, spring sowing can be carried out in early April, fall sowing in July or so.
Before sowing fennel, choose high-quality seeds, which can ensure a high germination rate, preferably choose the new seeds picked that year, which are required to be ripe, full and intact, and sieve out the broken and infected seeds, and then soak them into warm water to encourage the seeds to absorb the water and soften them, and then finally mix the seeds with phoxim.
Fennel sowing method
1, selection of seed soaking
Before planting fennel, you need to pick out the seedlings or seeds with high yield and strong resistance to disease, and if you use the sowing method of planting, put the seeds into warm water for a day and a night, and then use water to rinse off the epidermis. Rinse them well, and then place them at 25 degrees to germinate.
2, the soil is suitable
In order to ensure that the sowing of fennel seedlings fast and good, to choose loose fertile sandy soil as seedling nursery substrate, in the soil to apply basal fertilizer, usually the use of manure, is conducive to enhance the quality of the substrate, and then deep plowing of the plot, and dug out a 5-centimeter-deep furrow.
3, sowing seedlings
Take out the germinated fennel seeds, sow them evenly in the gully, and cover a layer of fine soil 2 cm thick on top, then water well to keep the substrate moist, to help the seeds come out quickly, and if planted in the early spring, you need to cover a layer of straw.
4, seedling management
After the fennel seedlings, pay attention to remove the weeds between the ridge, to reduce the loss of nutrients and water, found that the weak seedling, residual seedling and diseased seedling after the timely pull out, and then replenish the thriving seedlings, pay attention to the weeds and diseased seedling to be taken away from the field to destroy, so as not to breed underground pests.
