Spinach is a widely cultivated green vegetable in China, with very high nutritional value, and among many green leafy vegetables, spinach is very easy to plant and manage, on the one hand, spinach can be planted all year round, on the other hand, spinach has a short growing period, fast growth rate, and a long sustained harvest period.
Spinach planting conditions
Spinach can be sown in spring, summer, fall and winter in all seasons, spinach seeds can germinate at a temperature of 4 ℃, 15-20 ℃ is optimal, 25 ℃ or more will grow poorly, spinach leaves are large in size and need sufficient water, otherwise, in the case of high temperatures and long sunshine and drought, the nutrient growth will be inhibited.
Spinach planting steps
1, soil selection:
Spinach likes to grow in fertile areas, because it has a shallow root system, and this soil is also conducive to germination after sowing, so it needs to be y plowed, and in general, deep tilling should be followed by water.
2, germination:
Before sowing, it should be germinated once, generally the right temperature into the water for about 3 days, when the seeds will grow new buds, which is the best state of sowing, and if the water quality deteriorates, it is necessary to replace the water in time to ensure that it is clean.

Spinach high-yield management points
1, improve the seedling rate:
In order to improve the seeding rate of seeds, in the summer and early fall season when sowing, must remember to soak the seeds germination, soak the seeds germination and then sowing, even if the soil temperature is relatively high to ensure that the rate of seeding.
2, reasonable fertilization:
Generally speaking, green leafy vegetables have a higher demand for nitrogen fertilizer, fertilizer can be used with ammonium sulfate or urea, with the water can be flushed 1-2 times, which can promote the growth of stems and leaves.
3, prevention and control of pests:
