Spinach is a vegetable that is very suitable for autumn cultivation. Its nutritional value is obvious to everyone. It is a vegetable that people like very much. Because the stems and leaves are relatively tender, they are often used for single-fry, soup, and stir-fry with amaranth. With a variety of dishes, often eating autumn spinach has good effects on patients with hypertension, night blindness, and muscle relaxation. So what methods should be paid attention to to grow high yield and good quality spinach? Let ’s check it out together!

How to improve the yield and quality of autumn spinach

1. Spinach planting time: The most suitable planting time for spinach is spring and autumn. The spring planting time is between March and May each year, and the autumn planting time is from August to October each year. In addition, spinach can be grown in winter and summer, but the growth is not as good as spinach in these two seasons.

Selection of spinach varieties: Autumn is the most suitable season for spinach cultivation. The spinach grown in this season has good growth, thick leaves, less pests and diseases, and fast growth. Most spinach varieties are suitable for planting. When selecting specific varieties, you can choose varieties with strong cold resistance, good resistance and stable yield for planting.

2. Soil preparation and fertilization: Spinach must be well prepared and fertilized before planting to lay the foundation for high yield in the later period. The main root of spinach grows deeper, and the cultivated land needs to be plowed in advance. The plowing depth is about 20 cm. Before planting autumn spinach, about 4,000 kg of rotten organic fertilizer should be applied per acre of land, and 25 kg of superphosphate should be used together.

3. Spinach sowing: Spinach seeds can be properly germinated before sowing, which can save time for seedlings. The method of germination is relatively simple, soak the spinach seeds in water for about 12 hours, remove the mucus from the seeds, and put them on a wet cloth to promote germination. Generally, the spinach seeds will be exposed in about three days, and sowing can be performed Already. Spinach seeds can be directly sown, and the amount of seed used per acre is about 5 kg. If the seeding time is later, the seeding amount can be appropriately increased. After sowing, cover a layer of thin soil to keep the soil moist. Spinach can complete the emergence process in about 5-7 days.

4. Spinach management: In the process of spinach growth, the most important thing to pay attention to is the problem of topdressing and watering. Here we mainly talk about these two aspects. The first is fertilization. In the early stage of spinach growth, there is almost no need for topdressing. It mainly depends on the base fertilizer in the field to supply spinach for growth. After the spinach grows into the middle and late stages, one or two quick-acting nitrogen fertilizers can be appropriately applied according to the growth of the spinach, and ammonium sulfate can be applied with water at about 15 per acre. During the fertilization process, pay attention not to spread fertilizer in the heart of the leaves as much as possible to avoid causing fertilizer damage.

The second is watering. The spinach needs more water during its growth. Sufficient water is beneficial to the growth of leaves and increase yield. Watering needs to be done according to the wet and dry conditions of the field and the weather conditions. In the autumn season when rain is abundant, it is necessary to control the amount of watering and do a good job in field drainage to avoid water accumulation in the field and cause spinach root rot. If there is less precipitation, the field is generally watered for about one week to ten days, and watering is carried out according to the field conditions. After the watering, the soil is stippled in time to avoid soil compaction and reduce moss growth.

5. Timely harvesting: In order to obtain good spinach yield, it is naturally indispensable to harvest in time. Spinach grows faster, and generally can be harvested 30 to 50 days after planting. Harvesting can be done in batches according to market conditions. Generally, autumn spinach can be divided into two harvests.
