When is spinach planted, and when is spinach planted

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.

Spinach can be grown all year round.

Spinach is generally sown by the method of sowing, and is divided into spring spinach, summer spinach, autumn spinach, and winter spinach according to the planting season. The planting of spring spinach is generally at a temperature of 5 or more, and March is a good sowing period 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.

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.

Seed picking. 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.

Shade and hydrate. After sowing, you can water a little, remember not to water too much. In summer and autumn, the seeds should be covered with straw or shade nets, so as not to affect the development of seeds due to the intensity of the sun, and the soil should be kept warm and moist.

Spinach sown in spring and winter, because of the low temperature, is generally covered with plastic film to maintain the temperature and promote seed development.

Fertilization requirements. Spinach grows quickly and generally sprouts about seven days after sowing. When it grows true leaves, it is necessary to apply a clean manure water to it to provide nutrients for the growth of spinach.

Spinach is generally fine with farmhouse fertilizer, and urea can be applied once after it grows to more than ten centimeters.

Planting time: Spring spinach is planted in March 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.

The temperature conditions are different in different regions, and the ripening cycle of different spinach varieties is also different, and the planting time of autumn spinach is generally in.

August-September. The planting time should be determined according to the characteristics of the spinach variety and the climate and environmental conditions of the planting area. Planting technology: clean the seeds first, soak them in clean water for 3-5 days, and sow them when the seeds grow shoots.

The sowing method of sowing seedlings and raising spinach is generally sown, and the sowing is sown after the furrow surface is watered enough. If you sow seeds in spring and winter, you can directly sow dry seeds or wet seeds, and the number of seeds per mu is about 3 kg. Variety selectionThere are two main varieties of spinach, round leaves and pointed leaves, and you can choose cold-tolerant sharp-leaf spinach or heat-resistant round-leaf spinach according to the climate.

Spinach is mainly divided into spring spinach, summer spinach, autumn spinach, and overwintering spinach, so that we probably know when to plant spinach, and it can be sown all year round, and at the same time, germination treatment should be carried out in the hot season during the sowing process, and timely watering should be carried out during the growth period, and fertilization should be from less to more, so that the yield will be high.

1. Spring planting

Spinach is generally sown when the temperature rises above 5 in spring, and it is best to start planting in March, about 30 to 50 days later, the variety is fat, and the taste is better.

2. Summer planting

If you plant spinach in summer, it is usually sown from early June to mid-July, and it can be harvested in about 50 days, but the summer spinach has low nutrients and low yield due to the high temperature and rapid differentiation of flower buds.

3. Autumn planting

Spinach planting in autumn is the most suitable, generally in August and September to start sowing, about 30 50 days later can be harvested in batches, because the temperature difference between day and night in autumn is large, spinach at this time is rich in nutrients, but also the maximum yield.

4. Winter planting

The time of planting spinach in winter is generally in early October, and it can be harvested before the Spring Festival.

If you plant spinach in the hot summer, you must carry out germination treatment under the condition of 15 20, you can first soak the seeds in 15 water for about 10 hours, and then dry, and cover it with film after sowing, so as not to affect the growth of too strong sunlight.

It is best to ensure timely watering of spinach during the growth period, otherwise the roots can not effectively absorb nutrients, so that spinach will have high yield, good quality, and better nutritional taste.

Spinach fertilization is best maintained from less to more, from light to thick principle, when the growing period is vigorous, the more fertilizer is needed, generally the last fertilizer can be applied 2 weeks before harvesting.

1. Spinach can be planted all year round, because of its different 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.

2. Spring spinach planting time. Spring spinach is suitable for sowing in early spring, the sowing temperature of spring spinach is 4-5, and sowing can be started in northern areas when the soil surface layer is thawed at 4-6 cm. In Northeast China, it is generally sown in April and May and harvested in May and June. In North China and Central China, it is sown in February and March and harvested in April and May. The basin is sown in February-April, sown in March, and can be harvested in 1-2 months.

3. Summer spinach planting time. Summer spinach is sown in May-June and harvested in July-August. High temperature and strong light in summer are the limiting factors for the germination, emergence and plant growth of summer spinach seeds, which are easy to cause low yield and poor quality, so the planting and maturity time of summer spinach is short and the quality is also good.

4. Autumn spinach planting time. When autumn spinach is sown, the temperature is kept at about 20, and the quality and yield of autumn spinach are good. Northeast China, North China, Inner Mongolia, Xinjiang and other places are sown from late July to early August, and can be harvested from September to October; The basin is sown in August-September and harvested in batches 30-40 days after sowing.

5. Winter spinach planting time. Winter spinach is generally harvested in the spring of the second year, also known as root spinach, frozen spinach, and white dew spinach. The seeds are sown at 12-15 o'clock, and the river basin is sown from October to November, and in North China, it is sown in mid-to-late November, and harvested from late March to late April.

Different regions can sow seeds according to changes in their temperatures.

Growth cycle: about 35 days for spinach in autumn, about 45 days in winter and spring, depending on the temperature, it can be planted throughout the year, but it is more difficult in summer.

Management: 1. After the autumn spinach comes out of the true leaves, pour 1 time to clear the manure; After 2 true leaves, combined with seedlings, weeding, top dressing first light and then thick, and more decomposed manure was applied in the early stage; Top dressing 2-3 times during the peak growth period, 5-10 kg of urea per mu each time.

2. Keep the soil moist after winter spinach sowing. When there are 3-4 true leaves, properly control the water to facilitate overwintering. When there are 2-3 true leaves, the seedling spacing is 3-4 cm.

According to the seedling condition and weather, water and fertilizer were applied top-notch, and the feces and urine of ripe people were mainly decomposed. Frost and ice and snow weather should be covered with plastic film and shade nets for insulation, which can be covered with small arches. After the beginning of spring, choose a sunny day to apply well-rotted light manure water to prevent early sprouting.

3. Spring spinach should be covered with plastic film in the early stage of insulation, which can be directly covered on the furrow surface, and the film will be removed or changed to a small arch shed cover after the seedlings emerge. Top dressing fertilizer water, in the early stage, apply lightly and diligently with decomposed human and animal manure, and apply fast-acting nitrogen fertilizer in the later stage, especially 15 days before harvest.

4. After the summer spinach emerges, it is still necessary to cover the shade net, cover it in the sunny day, and cover it late and cover it early, so as to facilitate cooling and heat preservation. Watering at the seedling stage should be done in the morning or evening with small water and frequent watering. After 2-3 true leaves, apply two fast-acting nitrogen fertilizers. Water should be poured after each fertilization application to promote growth.

Spinach (Spinacia oleracea L.)Also known as Persian vegetables, red root vegetables, parrot vegetables, etc., it belongs to the genus Spinach in the subfamily Chenopinaceae, an annual herbaceous plant. The plant can be up to 1 m tall, with conical, reddish-tingting, less white, halberd-shaped to ovate, bright green, entire-edged or with a few tooth-like lobes.

There are many types of spinach, which can be divided into two varieties, thorny and thornless, according to the seed form. Spinach is native to Iran and is commonly cultivated in China as one of the most common vegetables.

Spinach can be grown all year round.

Sunshine. Spinach is a long-day crop, and the plants are easy to moss and bloom under high temperature and long sun conditions. The requirements for sunshine intensity are not strict, and it can be intercropped with high-pole crops.

Moisture content. Spinach leaves have a large leaf area, tender tissue, and high water requirements. Sufficient moisture, thick meat when growing vigorously, high yield, good quality. Under the conditions of high temperature, long sunshine and drought, vegetative growth is inhibited, reproductive growth is accelerated, and it is easy to extract moss from immaturity.

Soil. Spinach is highly adaptable to the soil, but it is still better to have fertile soil with strong water retention and fertility. Spinach is not acid-tolerant and has a suitable pH. Spinach is a leafy vegetable that requires more nitrogen fertilizer and appropriate phosphorus and potassium fertilizers.

How to buy spinach

1. When buying spinach, see if it has a strong green color. Whether the roots are red or not, such spinach is better.

2. Choose more tender spinach, which is manifested as unold stems and leaves, flowering without moss, etc., and do not buy spinach with yellow wilted leaves.

3. If you find that the spinach leaves are partially dark yellow, discolored, etc., do not buy.

4. Choose spinach with thick leaves, and it is better to hold the roots with your hands and stretch out, which is suitable for buying.

5. Choose spinach with larger leaves, which have a wider leaf surface and a shorter petiole is the best. Spinach is rich in vitamins A, B, and C that can help you get out of your restless state, drive away tension, and improve your mood of depression.

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.
