How to grow spinach for high yield

Spinach is a very common leafy vegetable on the table in China, which has a very large planting area. With the increasing demand of spinach market, the output of spinach urgently needs to be increased. Increasing the output of spinach can not only meet the market demand, but also improve the planting efficiency for growers. So how to grow spinach in order to produce high yield? The following editor will give you a brief introduction, let's have a look!

1. Variety selection

If you want to increase the yield of spinach, the selection of varieties is very critical. We should ensure that the varieties have good production capacity, strong disease resistance, thick leaves and dark color. And because the nutritional value of spinach is high, the planting benefit is obvious, so the selection of varieties is very critical. After selecting the variety, we also need to accelerate the germination and disinfect the seeds before sowing, and soak the seeds with warm water and chemicals. Eliminate the germs in the seed and improve the germination rate of the seed.

2. Soil preparation and fertilization

If the previous crops in the soil are fruit and vegetable crops, less organic fertilizer can be applied when growing spinach. Because the growth of fruits and vegetables has a great demand for organic fertilizer, it is only necessary to apply some compound fertilizer. First of all, we have to turn the soil deeply, then rake it flat and loosen it, and hold the border surface flat. Then apply compound fertilizer, generally about 450g per square meter. If the previous crop is vegetables, then fertilizer is relatively less, so each mu also needs to apply about 5000kg farm manure, mixed with the soil, to prepare for sowing.

3. Sowing seeds at the right time

We should regulate the sowing time according to the planting area, for example, if we plant in the north, then we should sow the seeds after the National Day. The dried seeds with low purity and many impurities should be selected before sowing to ensure the growth ability of seedlings and seedlings, usually about 10g per square meter. The main method of spinach seed sowing is to sow the seeds evenly on the border surface. Then rake the border again, keeping the depth at about 1.2 cm. Then gently compacted and properly watered to promote seed germination.

4. Management after sowing

The temperature difference between day and night after sowing is relatively large. When the temperature is high during the day, the greenhouse film should be opened properly to do a good job of ventilation and cooling. At night, the greenhouse film should be covered back to keep warm. About 5 days after sowing, spinach seedlings should be guaranteed, so proper watering should be done two days after sowing. After emergence, the soil should be kept moist to meet the water demand of spinach. Finally, we should do a good job in the prevention and control of weeds, properly control the use of paraquat and other chemicals, and pay attention to controlling the concentration to avoid drug damage to seedlings.

The above is a brief introduction to how to grow spinach for high yield. Spinach planting method is relatively simple, if you want high yield, then management is very important, so we must pay more attention. That's all for today's introduction.
