Spinach planting method and time of months sowing

The planting time of spinach varies according to different regions, taking Shandong as an example, the open-air spinach in autumn starts from the beginning of autumn, and starts to be planted from the west of Shandong to the east in turn, to the Jiaodong Peninsula.

The planting time is around August 10th, and the harvest is around October 5th. The overwintering spinach was planted before October 15th, watered and mulched before freezing, during which time the film was punched to dissipate heat, and harvested around April 10th of the following year.

The planting method can be carried out precision sowing and cocooning, the amount of seeds used for precision sowing is small, about catty of seeds per mu, there is no need to thin seedlings relative to cocoon sowing, but the cost of planting machinery is high, if the seedlings are not good, there is a risk of lack of seedlings, the amount of cocoon sowing is large, the amount of seeds per mu is about catty, and the seedlings need to be thinned after the seedlings emerge, and the row spacing of open-air planting is about 16cm, and the plant spacing is about 5-7cm.

Spinach is a kind of vegetable with obvious seasonal ratio in the previous planting, but later with the progress of planting technology and the research and development of varieties, it can basically be planted in four seasons, but it is best to sow in mid-March in spring, and the temperature change in summer is more obvious, so that the yield will be higher in batches, so the first batch is sown at the beginning of May, the second batch is sown at the end of June, and the third batch is sown at the beginning of July. In autumn, sowing can be carried out throughout the season, and in winter, sowing can only be carried out in November, otherwise it will freeze to death, so there is the most suitable time for planting every season, so be sure to grasp it. Spinach, also known as Persian cabbage, red root cabbage, parrot cabbage, etc., belongs to the genus Spinach in the Chenopinaceae family, and is an annual herbaceous plant.

The leaves are halberd-shaped to ovate, bright green, tender and juicy, slightly shiny, entire, or with a few tooth-like lobes.

Spinach is grown by preparing seeds, preparing soil, and sowing seeds. Spring spinach can be sown around March, summer spinach is sown in May-July, autumn spinach is sown between August and September, and winter spinach is sown around October-November

1. Prepare the seeds

Spinach seeds are prepared before planting, and varieties are selected according to the time of planting and the local climate, and the seeds are selected for good quality and freshness. Before sowing, in order to improve the activity of seeds and improve the germination rate, the seeds can be dried for one or two days in advance, the seeds can be soaked in warm water, and then placed in an environment of 20-25 to promote germination.

2. Prepare the soil

Spinach has thick roots, easy to absorb water, and has high requirements for soil, so it should be kept in suitable soil in order to grow normally. It is best to choose a soil with fertile soil and strong drainage for spinach, and mix coarse sand, coal ash, etc. in the soil to increase air permeability. Before sowing, tidy up the soil to provide a good environmental basis for seed germination, turn the soil 20-30 cm deep, and apply a small amount of thin fertilizer.

3. Carry out sowing

After the seeds are sorted out, the seeds are evenly sown on the surface of the soil, covered with a thin layer of soil, covered with the seeds, and poured in enough water to keep them moist. If you sow in summer and autumn, you can use shade nets and straw to block out excessive sunlight. If you sow seeds in spring or winter, you can cover them with a film to maintain the temperature and promote seed development.

After the seedlings emerge, the seedlings can be planted in time, and the thin fertilizer can be applied appropriately.

Seeding time

Spinach can be sown all year round, spring spinach can be sown around March, summer spinach is sown between May and July, autumn spinach is sown between August and September, and winter spinach is sown around October and November.

Spinach is sown in March in spring, May and July in summer, and August and September in autumn.

Spinach can be grown all year round, with a short growth cycle and a quick harvest. Sowing can be done when the spring temperature is above 5, usually sown in March in spring, and can be harvested after 40 days; In summer, sowing can be done in May-July; In autumn, it is sown in August and September, and the overwintering spinach can be sown in October and November, and it can be harvested around the Spring Festival. In short, seeds can be sown at the right temperature.

Sowing spinach way:

1. Fine-grained land

Plough the land, choose a loose and fertile soil, good drainage section, apply 4000 kg of rotted organic fertilizer per mu, add 40 kg of superphosphate, mix soil and fertilizer, and finely prepare the land to make a field furrow. It is suitable for flat furrows in summer and autumn, and high furrows are suitable for winter and summer, and can be made of meter-wide furrows.

2. Sow seeds and raise seedlings

The seeds can be soaked in water about a week before sowing, fished out and cleaned after 12 hours, placed in the environment of 4 and waited for 24 hours, and then placed in the environment of 20-25 to promote germination, and can be sown after germination in 3-5 days. After watering, sow the seeds and cover them with fine soil.

After sowing in summer and autumn, use a small arch shed, put on a shade net to avoid direct sunlight, and sowing in winter needs to be covered with plastic film for insulation and cold resistance, and the film can be removed after the seedlings emerge.

3. Leave seeds for harvesting

The plant can be harvested when it grows to more than 10 cm, and the spinach used to keep the seeds should be controlled in the water during the budding period, and the male plant can be pulled out after the male plant bears seeds.

1.Sowing seeds and raising seedlings. The method of cultivation of spinach is spreading.

Before sowing, soak the sown sails in water for 12 hours. After soaking, they are kept in the refrigerator for 24 hours. After taking it out, it is placed in an environment with a temperature of 20-25 degrees Celsius to call for cleft buds.

After germination, it is ready to be sown. 2.On-site management.

Spinach has a strong growth ability and can grow on its own as long as it emerges. However, in order to ensure the yield, it is necessary to thin the true leaves when they grow, and at the same time, they can be weeded in time. 3.

Spinach can be grown all year round. Because of its different planting time, it can be divided into four varieties: spring, summer, autumn and winter. These four varieties have different light intensities and durations.

Spring spinach is planted in early spring March. Sowing can be done when the temperature rises by more than 5 degrees Celsius in spring, and harvesting can be done 1 to 2 months after sowing.

1. Sow seeds and raise seedlings. The spinach planting method is to spread, soak the seeds in water for 12 hours before sowing, put them in the refrigerator for 24 hours after soaking, take them out and place them in the environment at a temperature of 20-25 degrees to germinate, about 3-5 days to germinate, and after germination, you can sow seeds.

2. Field fiber management. The growth of spinach is strong, as long as it emerges, it can be allowed to grow on its own, but in order to ensure the yield, it needs to be thinned when it grows true leaves, and the seedlings can be removed in time at the same time.

3. Spinach can be planted all year round, because of its different oak planting time, it can be divided into four varieties of spring, summer, autumn and winter, and the intensity and duration of light are different for the four varieties. Spring spinach is planted in early spring in March, and can be sown when the temperature rises above 5 degrees Celsius after the beginning of spring, and can be harvested in one to two months after sowing.

How to grow spinach:

1. Planting time

Spinach is generally sown and can be grown all year round. According to the planting season, it is divided into spring spinach, summer spinach, autumn spinach, and winter spinach. The planting of spring spinach is generally at a temperature of more than 5°, and March is the best sowing time every year; Summer spinach is generally planted in May to July; Autumn spinach is generally planted in August to September; Winter spinach is generally planted in mid-October to early November.

2. Soil selection.

The roots of spinach are thicker, deep in the soil, and easy to absorb water. It has high requirements for soil, and it is generally necessary to choose high-quality soil with fertile soil and strong drainage. If you can, add a little coarse sand or soot to the soil, which can increase the air permeability of the soil, facilitate the rooting of seeds in the future, and will not affect the growth of spinach.

3. Seed selection.

The survival rate of spinach planting mainly depends on the quality of the seeds, and when planting, we must ensure that the seeds are still within the shelf life, if the shelf life has been exceeded, then the germination rate will be very low. Choose the seed variety according to the local temperature conditions, and if the temperature is high, you can choose the heat-tolerant variety; If the temperature is cool, you can choose a cold-tolerant variety. Of course, the better the quality of the seeds, the higher the germination rate.

4. Seed sowing, spinach is generally sown.

When sowing seeds in summer and autumn, the seeds should be soaked in water for more than 12 hours a week before sowing, and then stored in a place with an ambient temperature of only 4C for 24 hours, and then germinated at a temperature of 20 25 °C, and then sown after the seeds germinate.

Choose loose and fertile land with good water and fertilizer retention, and good drainage and irrigation.

Seeds: Choose healthy, resistant spinach seeds, soak them in clean water for 12 hours, then remove them and place them in a warm environment to germinate.

Usually choose loose and fertile soil with water and fertilizer retention, apply sufficient base fertilizer and then level the furrow, and sow the seeds into it. After sowing, it is necessary to water enough, then lightly rake the topsoil, bury the seeds, and cover with a layer of plant ash, and pay attention to shading in summer and autumn.

Prepare the land for furrowing. To grow spinach, it is usually necessary to choose loose and fertile, water and fertilizer retaining land, good drainage and irrigation, and in order to improve the fertility of the soil, it is necessary to fertilize it when preparing the land. Usually 4000 kg of organic fertilizer per mu, 40 kg of superphosphate, after fertilization needs to be leveled for furrowing, winter and spring to do high furrowing, summer and autumn more use flat furrow, the width of the furrow is meters.

1. Seed selection and germination: varieties such as round-leaved spinach or large-leaf spinach with strong 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 it at a temperature of 2 4 for low temperature germination, to turn the seeds frequently, keep them moist, generally after 4 5 days can germinate and sow.

2. Timely sowing: spinach planting can be divided into spring sowing, summer sowing, autumn sowing, and overwintering spinach, which is generally sown. Before spring sowing and autumn sowing, the seeds should be germinated, soaked in clean water first, then placed at a low temperature for a day, and then placed at a temperature of about 20 degrees for germination.

Spring-sown and overwintered spinach can be sown directly. Choose loose and fertile soil before sowing, and be sure to apply sufficient basal fertilizer.

3. Later management: after spring sowing, it should be covered with plastic film for insulation, and it can be changed to an arch shed after emergence, and it can be uncovered when the weather is good to let it see more sun. Summer sowing should pay attention to high temperature, you can choose to cover the shade net, to achieve the effect of cooling, and water frequently in the morning and evening.

Nitrogen fertilizer can be applied once after the autumn seedlings grow leaves, and the soil should be moistened after winter sowing, and the temperature should be kept warm when the temperature is too low.

Precautions for spinach planting

1. When spinach is planted, the soil should be slightly tidied up, and when the soil is tidied up, some coal ash or coarse sand should be sprinkled on the side of the land, which is to increase the permeability of spinach during growth, because the root system of spinach is relatively coarse when it grows in the later stage, so we should choose such soil.

2. When processing seeds, the seeds should be soaked in water for a day, and then the seeds should be taken out, wrapped in gauze, and sown again every two days, but during this period, the water should be changed every day, and the temperature should be kept between 25 degrees and 30 degrees.
