How to grow spinach for high yields? A detailed guide to the latest growing methods
Spinach is a very common leafy vegetable on tables in our country, and it is grown on a very large area. As market demand for spinach increases today, spinach yields also urgently need to increase. Increasing spinach yields can not only meet market demand, but also has the effect of improving growing returns for growers. So how should spinach be grown to achieve high yields? Below, the editor will give everyone a brief introduction. Let's take a look together!
1. Variety selection
To increase spinach yields, variety selection is very key. We must ensure the planted variety has good production capacity, strong disease resistance, and thick, dark leaves. Moreover, because spinach has high nutritional value and relatively obvious growing returns, variety selection is very key. After selecting the variety, before sowing we also need to carry out seed germination promotion and disinfection work, soaking the seeds with warm water and chemicals. This eliminates pathogens inside the seeds and improves the seed germination rate.
2. Land preparation and fertilization
If the previous crop in the soil was a fruit vegetable crop, then when planting spinach, organic fertilizer can be applied appropriately in smaller amounts. Because the growth of fruit vegetables has a very large demand for organic fertilizer, it is only necessary to spread some compound fertilizer. First, we need to deep plow the soil, then rake it level and loosen it once, and rake the bed surface smooth. Then apply compound fertilizer, generally spreading about 450g per sq m. If the previous crop was a vegetable, then the fertilizer is relatively less, so about 5000kg of farmyard manure still needs to be applied per mu, mixed with the soil, and beds made ready for sowing.
3. Timely sowing
We need to regulate the sowing time according to the growing region. For example, if growing in the north, then sowing should be done after National Day. Before sowing, remove shriveled seeds with low purity and many impurities to ensure uniform emergence and seedling growth capacity. Usually, sow about 10g per sq m. The main sowing method for spinach seeds is broadcasting, evenly scattering the seeds on the bed surface. Then rake the bed surface once more, keeping the depth at about 1.2 cm. Then press lightly and water appropriately to promote seed germination.
4. Management after sowing
After sowing, the temperature difference between day and night is relatively large. When daytime temperatures are high, the greenhouse film should be appropriately opened to do good work in ventilation and cooling. At night, the greenhouse film should be put back to keep warm. About 5 days after sowing, spinach should achieve uniform emergence, so two days after sowing it should be watered appropriately to ensure uniform emergence. After emergence, the soil should also be kept moist to meet spinach's water needs. Finally, do good work in weed control, using chemicals such as paraquat for appropriate control, and be careful to control the concentration well to avoid pesticide damage to the seedlings.
The above is a brief introduction to how to grow spinach for high yields. Spinach growing methods are relatively simple. If you want high yields, then management is very important, so everyone must pay close attention. That is all for today's introduction.
