The main points of planting spinach in the latest Spring

Spinach is delicious and tender, rich in nutrition, deeply loved by everyone, especially the planting of spinach in spring is extremely important to alleviate the spring dull. And now the temperature is also gradually rising, at a good time for spinach planting, generally sowing 30 to 50 days can be harvested on the market. So how to grow spring spinach? Come and have a look with the editor.

1. Preparatory work

The temperature in early spring is still relatively low, and the light time in the later stage is poor, so leafy vegetables are very prone to bolting, so varieties that are not easy to bolting must be selected. The planted plots should be plots that have not planted cruciferous vegetables in the previous crop, and should be turned over in time after the previous harvest to clean up the residual roots and weeds. When the soil is thawed in early spring and dispersed as soon as it is touched, 2000 kg of rotten organic fertilizer, 25 kg of urea and 10 kg of potash fertilizer are applied per mu, and then shallow ploughing is made to prepare for sowing.

2. Sowing seeds

The temperature of spring spinach sowing is still relatively low. If the seeds are not only soaked before sowing, it will take at least half a month after sowing to emerge. If we adopt the method of soaking seeds to promote germination, first soak the seeds in warm water for 5 hours, remove and dry them and put them in a greenhouse environment of 25 degrees to accelerate germination. Generally, the seeds can be sowed in 2-3 days, which can greatly shorten the time of sprouting and promote strong seedlings. There are many ways to sow spinach, the most common one in early spring is wet sowing, first watering the bottom water, and then sowing the seeds under the water and then covering the soil by 1 centimeter.

3. Field management

Because the temperature is lower in early spring. Therefore, it is recommended to cover the plastic film once after sowing, which can play an excellent role in warming and moisturizing. It should be noted that the seedlings should be removed in time after they are unearthed, or build a small arch shed. The purpose of this is to make the seedlings see more light and refine the seedlings, but also to burn the seedlings at high temperature, and to pay attention to the cover of the small arch shed during the day and night and the cover of rain and sunshine. On the other hand, wet-sown spring spinach is usually watered once when 2-3 true leaves are grown, and then followed by soil and climate change because of sufficient soil water. During the second watering, 15 kg of urea was applied per mu with water, especially in the first half of the harvest.

4. Timely harvest

Spring spinach should be harvested timely according to growth and production demand. The yield of early harvest is too low, and it is easy to bolt too late, which reduces the commodity value and affects the final benefit. After harvest, crops such as peanuts or corn can be held in the next crop, or other crops can be sown.
