Key points of planting spring spinach

Spinach is tender and delicious, rich in nutrients, and loved by everyone, especially in spring planting spinach, which is extremely important to alleviate spring light. And now the temperature is also gradually rising, it is a good season for spinach planting, generally sowing thirty or fifty days can be harvested on the market. So how do spring spinach grow well? Let's take a look at it together with Xiaobian.

1. Preparation

The temperature in early spring is still relatively low, and the late light time is poor, leafy vegetables are prone to bolting phenomenon, so when selecting varieties, we must choose varieties that are not easy to bolt now. The plot planted should be the plot where cruciferous vegetables have not been planted in the previous crop. After the previous crop is harvested, the plot should be deeply turned in time to clean up the residual weeds. When the soil thaws in early spring and disperses at a touch, 2000 kg of decomposed organic fertilizer, 25 kg of urea and 10 kg of potassium fertilizer are applied per mu as the ground, and then shallow tillage is carried out to prepare for sowing.

2. Sowing

Spring spinach sowing temperature is still relatively low, if not only seed soaking germination treatment before sowing, sowing after at least half a month to emerge. If the method of seed soaking and germination is adopted, the seeds are first soaked in warm water for 5 hours, removed and dried, and then placed in a greenhouse environment of 25 degrees for germination. Generally, 2-3 days can be sown, which can greatly shorten the germination time and promote the seedlings. Spinach and there are many ways to sow, the most common early spring is wet sowing, first watering the sole water, such as water infiltration and then sowing seeds after covering soil 1 cm.

3. Field management

Because early spring temperatures are lower. Therefore, it is recommended to cover a plastic film after sowing, which can play an excellent role in warming and moisturizing. Attention should be paid to removing the seedlings in time after they are unearthed, or to build a small arch shed. The purpose of doing this is to let the seedlings see more light, more training seedlings, but also to burn the seedlings in high temperature, but also pay attention to the small arch shed day to open the night cover, sunny to open the rain cover. Spring spinach sown wet, because the soil moisture is sufficient, generally in the growth of 2-3 true leaves when watering once, and then follow up soil and climate change watering. When watering for the second time, urea 15kg per mu is applied with water, especially quick-acting nitrogen fertilizer is applied half a month before harvest.

4. Timely harvest

Spring spinach should be harvested according to growth conditions and production needs. Harvesting too early and yield too low, and harvesting too late is easy to bolt, reducing the commodity value and affecting the final benefit. After harvesting, the next crop can be either peanut or corn, or other crops can be sown.
