1, soil selection
Spinach has a strong root system and strong soil grasping ability in the late growth stage. Therefore, when selecting soil, it is best to choose humus soil with high nutrients and strong drainage ability, and finally add a proper amount of fly ash or coarse sand, which can increase the permeability of soil.
2. Seed treatment
In the method of how to grow spinach, it is necessary to treat the seeds. Select excellent seeds and soak them in clear water 1 day, then take them out and wrap them with soaked gauze, and sow them three days later. During this period, water should be changed every day and the high temperature environment of 20 ~ 30℃ should be maintained.
3. Sowing process
Put the sprouted part of spinach in the prepared soil, and then cover it with a layer of soil. This method is very suitable for planting spinach in summer. If you sow in spring and autumn or winter, you can also choose to use the sowing method, which will be simpler and more convenient, but the germination time will be delayed.
4. Save water
Spinach needs watering after sowing. If it is planted in summer, we should not only keep the soil moist, but also do a good job of sun protection, otherwise it will affect the germination rate of seeds. If it is planted in spring and summer, it is necessary to cover the soil with plastic film to keep warm.
5, topdressing is suitable
Spinach has a strong growth ability. If the climate is suitable, buds can grow within 7 days after sowing. During this period, fertilization is not needed. When spinach grows to 2 or 3 leaves, it needs to be applied with manure cleaning water once, and then farmyard manure can be applied once every half month. When spinach grows to more than 10 cm, it needs to be applied with urea once.
