The planting method of spinach: selecting seeds to accelerate germination, timely sowing, and late management. Time: Spinach can be planted all year round.
1. Planting methods
1. Selecting seeds to accelerate germination: varieties such as round-leaf spinach or big-leaf spinach with heat resistance, easy germination and strong disease resistance should be selected. First, break the shell and add a new high-fat film to soak the seeds for 12-24 hours (to improve the germination rate), and then put them at 2℃-4℃ for low-temperature germination. Always turn the seeds and keep them moist, and it usually takes 4-5 days to germinate and sow.
2. Timely sowing: Spinach planting can be divided into spring sowing, summer sowing, autumn sowing, and overwintering spinach, which is generally broadcast. Before sowing in spring and autumn, seeds should be treated to accelerate germination. First, they should be soaked in clear water, then placed at low temperature for one day, and then placed at a temperature of about 2 degrees to accelerate germination. Spring sowing and overwintering spinach can be sown directly. Choose loose and fertile soil before sowing, and be sure to apply sufficient base fertilizer.
3. Post-management: After spring sowing, it should be covered with plastic film to keep warm. After seedling emergence, it can be changed into an arch shed. When the weather is good, it can be uncovered to let it see more sunshine. Summer sowing should pay attention to high temperature, you can choose to cover the sunshade net to achieve the effect of cooling down, and water it frequently in the morning and evening. After autumn sowing seedlings grow leaves, nitrogen fertilizer can be applied once, after winter sowing, the soil should be kept moist, and when the temperature is too low, heat preservation should be carried out.
second, the planting time
generally, spinach is sown, and spinach can be planted all year round. According to the planting season, it is divided into spring spinach, summer spinach, autumn spinach and winter spinach. In general, the temperature of spring spinach should be above 5℃, and March is the best sowing date every year. The planting time of summer spinach is generally from May to July. The planting time of autumn spinach is generally from August to September; Winter spinach planting time is generally from mid-October to early November.
ways of sowing spinach
1. Fine-grained land
Plow the land, select the area with loose and fertile soil and good drainage, apply 4 kilograms of decomposed organic fertilizer per mu of land, add 4 kilograms of calcium superphosphate, mix the soil and fertilizer, and fine-grained the land to make a field border. Summer and autumn are suitable for flat border, and winter and summer are suitable for high border, and 1.2-1.5 meters wide border can be made.
2. Seeding and seedling raising
You can soak the seeds in water about a week before sowing, take them out and clean them after 12 hours, wait at 4℃ for 24 hours, and then accelerate germination at 2-25℃. You can sow after sprouting for 3-5 days. Sow seeds after watering, and then cover with fine soil.
after sowing in summer and autumn, use a small arch shed and put up a sunshade net to avoid direct sunlight. In winter, sowing needs to be covered with plastic film for heat preservation and cold resistance, and the film can be removed after emergence.
3. Keep the seeds for harvesting
The plants can be harvested when they are more than 1 cm long. The amount of spinach used for keeping seeds should be controlled at the bolting stage, and the male plants should be pulled out after the seeds are produced.
