When is the best time to grow spinach? What can spinach be made of?

Summer spinach will be sown in May and July, and autumn spinach will be sown in August and September; Garlic spinach, scrambled eggs with spinach, cold spinach, spinach and pork liver soup, these delicacies made with spinach are rich in calcium, nutritious and delicious.

Growing environment.

1. Temperature. Spinach is a cold-tolerant vegetable, the seeds can germinate at 4 o'clock, the most suitable is 15-20, the temperature suitable for vegetative growth is 15-20, the growth is poor above 25, and the aboveground part can withstand the low temperature of minus 6-8.

2. Sunshine. Spinach is a long-day crop, and the plant is easy to moss and flowering under high temperature and long-day conditions, and the requirements for sunshine intensity are not strict, and it can be intercropped with high-stem crops.

3. Moisture. 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.

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

Cultivation techniques. After the autumn spinach has real 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.

The soil remains moist after winter spinach planting. 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.

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 after the emergence of the film or changed to a small arch cover, and the small arch shed will be covered by day and night, and the rain cover will be covered by sunshine, so that the seedlings can see more light, refine more seedlings, and time seedlings. 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.

Nutritional benefits of spinach.

1. Intestinal defecation, prevention and treatment of hemorrhoids. Spinach contains a large amount of plant crude fiber, which has the effect of promoting intestinal peristalsis, facilitating bowel movements, and can promote pancreatic secretion and help digestion. It has the best effect on hemorrhoids, chronic pancreatitis, constipation, anal fissure and other diseases.

2. Promote growth and development, enhance disease resistance. The carotene contained in spinach is converted into vitamin A in the human body, which can maintain normal vision and the health of epithelial cells, increase the ability to prevent infectious diseases, and promote the growth and development of children.

3. Ensure nutrition and improve health. Spinach is rich in carotene, vitamin C, calcium, phosphorus, as well as a certain amount of iron, vitamin E, rue II and other beneficial ingredients, which can provide a variety of nutrients to the human body; The iron element it contains has a good auxiliary effect on iron deficiency anemia.

4. Promote human metabolism. Some substances in spinach can promote human metabolism and improve physical health. Eating a lot of spinach can reduce the risk of stroke.

Spinach can be grown all year round, and the optimal time to grow is different for different spinach varieties. Spring spinach is best planted in March, summer spinach is planted in May and July, autumn spinach is planted in August and September, and winter spinach is suitable in October and November.

When planting spinach, you need to choose seeds with a complete surface, full, and free of pests and diseases, first clean the surface with water, rub off the shell of the surface, remove impurities and bacteria, and then soak in warm water for 1 2 days, remove and dry before sowing.

Cultivation techniques of spinach:

Spinach plots are generally sown. Summer and autumn sowing in 1 week before sowing the seeds soaked in water for 12 hours, put in the well or in about 4 refrigerators or refrigerators for 24 hours, and then in 20 25 conditions to germinate, after 3 5 days of germination sowing. Dry or wet seeds can be sown in winter and spring.

3 kg per acre.

After pouring the bottom water on the furrow surface, sow the seeds, lightly rake the topsoil with a tooth rake, so that the seeds are sown into the soil, and cover the furrow surface with a layer of plant ash. After sowing in summer and autumn, it should be covered with straw or covered with a small arch to prevent high temperature and heavy rain. Regularly keep the soil warm and moist, 6 7 days can be seedlings, winter sowing temperature is low, then cover the furrow with plastic film or shade net insulation to promote the emergence of seedlings, after the emergence of seedlings.

Spinach is divided into four types according to the different planting time: autumn spinach, overwintering spinach, spring spinach and summer spinach, and because of the different varieties, the sunshine length is also different.

Spinach planting time.

1. The planting time of autumn spinach.

Autumn spinach is sown in August and September, and can be harvested in batches 30-50 days after sowing. Varieties should be selected from early-maturing varieties that are more heat-tolerant and fast-growing, such as plowshare pine, Chinese pineapple No. 1, Guangdong round leaves, spring and autumn large leaves, etc.

2. The planting time of overwintering spinach.

Overwintering spinach is usually sown in mid-October - early November, harvested in batches around the Spring Festival, it is advisable to choose medium and late-maturing varieties with strong winter, late sprouting and strong cold tolerance, such as round-leaved pineapple, late-round-leaf pineapple, Chinese pineapple No. 1, Liaoning round-leaved pineapple, etc.

3. The planting time of spring spinach.

After the beginning of spring, when the temperature rises to more than 5 ° C, you can start sowing, March is the appropriate period for sowing, 30-50 days after sowing to harvest, varieties should choose late sprouting, late round leaf pine, spring and autumn large leaves, Shenyang round leaves, Liaoning round leaves, etc.

4. The planting time of summer spinach.

Summer spinach is often sown in stages from May to July, and harvested from late June to mid-September.

Spinach is particularly hardy, and the best temperature for growing is 15-20 degrees. Spinach plants can tolerate sub-zero temperatures for a long time and can resume growth after freezing at -8 -6 degrees. Thus, 4 6-leaf spinach seedlings can survive in the open field without any maintenance.

However, 1 2 true leaf seedlings and plants that are about to sprout are still not cold tolerant and need to be covered with a little mulch to safely overwinter. Eat spinach regularly, radiant, choose the right time, spinach cultivation is actually very simple! Because spinach is not resistant to high temperatures, when the temperature is above 25, the plant does not grow well, the leaves are small and few, the quality deteriorates, and it is easy to sprout.

Spinach is a typical long-day crop, which completes budding, flowering and fruiting after a photoperiod of more than 12 hours under light and high temperature conditions. As the temperature and sunlight increase, the spinach sprouting period will be earlier.

Spinach requires a lot of water during its growth. Lack of water during the growth period, spinach plants do not grow well, and spinach leaves age, resulting in poor quality and easy to sprout early. The straight roots of spinach are more developed.

He demanded that the soil be loose and fertile, with strong fertilizer and water retention and good drainage. Generally sandy loam and clay loam are suitable. The recommended soil pH is:

Eat spinach regularly, radiant, choose the right time, spinach cultivation is actually very simple! Based on the above characteristics of spinach growth, we all agree that sowing is the main way to sow seeds, usually in August-September. It is also possible to sow in advance until July or later to the beginning of October, and 30 to 40 days after sowing can be harvested in batches!

The sowing time of overwintering spinach is from late October to early November, and it is harvested in batches before and after, and it is necessary to select medium and late maturing varieties with strong wintering, slow budding and strong cold resistance. Then, the principle of sowing season and time is good, do the following to ensure that your spinach is fresh and tender. Soil preparation and ditching spinach must be planted after the previous crop has been harvested.

At this time, it is necessary to remove the fallen leaves of the previous stubble in time and turn the roasted soil deeply. At the same time of land preparation, it is recommended to apply 4500 6000 grams of decomposed organic fertilizer and 150 grams of lime per square meter. The land should be leveled.

It should be leveled into a high plot, and in summer and autumn it should be leveled into a flat land. The recommended border width is 120 150 cm. Growing time: Spinach is a vegetable that people eat regularly throughout the year.

Usually it can be grown all year round, but it is best to plant spinach in August-September. During this time, spinach can not only be better and more nutritious, but also increase the yield.

Seed treatment spinach can be sown directly in the soil, or you can buy mature spinach seeds in the market and then soak them in clean water for 3 5 days, which can promote the germination of spinach seeds and make them take root and germinate quickly in the soil. Soil requirements are actually quite simple. Normally, spinach seeds can be planted directly in the vegetable garden soil, or some leaves, organic fertilizers and other substances can be added to the vegetable garden soil, which can make the spinach seeds take root and germinate quickly in the soil, so that the spinach grows better.

To sow and germinate, first sprinkle the treated spinach seeds on the soil, and then cover a thin layer of soil to prevent the spinach seeds from being blown away by the wind. The soil is properly watered, and the temperature is maintained at about 15 in a cool place, and the seeds will take root and germinate in about a week.

Spinach is hardy but not heat-tolerant and can be sown in September November and February April every year.

It is best to grow spinach in the autumn because the temperature at this time is very suitable for spinach, and the spinach grown is also very productive.

Generally, there are many ways to eat spinach, such as boiled and fried, and it can also be roasted when eating barbecue, and then we must choose to plant spinach in winter, so that spinach is easy to survive.

Spinach is a one- or two-year-old vegetable and fruit, produced in Saudi Arabia and the Caucasus, and was introduced to China during the Han Dynasty and has a long history of cultivation. Spinach leaves are delicate and rich in minerals such as iron, calcium, phosphorus and a variety of vitaminsThe protein content is also high, it is a vegetable and fruit with high edible value, and it is also a vegetable and fruit that everyone widely likes in China, and the total planting area is relatively large. Spinach is the most common leafy vegetable species in the small vegetable garden of the farmhouse, it only takes about 40 days from planting to obtaining, it is resistant to low temperature and drought, and it is very scoundrel, so it can be planted all year round as long as you love to eat.

The best time to plant is to make a thorough decision about when you love spinach. Spinach is of the Chenopodaceae family.

The first and second annual dwarf green plants, also known as arabic grass and red root vegetables, are produced in the central and western parts of Asia, and have been planted for more than 2,000 years. Spinach is rich in nutrients, rich in vitamins and minerals, the leaves are soft and delicious, and the roots are sweet and edible, which is favored by many customers. Spinach is the most common vegetable, it is high in nutrients, rich in vitamins, minerals, delicious taste, and loved by many customers.

Its growth period is very short, from the time of planting, to the time it can be taken and obtained, it only takes about 40 days. It can be grown all year round, but it generally bypasses the warmer summer months. Pick spring, autumn and winter planting.

Spinach has strong cold resistance and adaptability, a relatively short growth period, and can be planted in multiple crops in a year, which is a vital green leafy vegetable in spring, autumn and winter. Spinach is not heat-tolerant, and when the ambient temperature exceeds 25, spinach plants grow and develop poorly.

The leaves will be small and few, the quality will be poor, and it will be very easy to sprout. Spinach needs a lot of water in the growth process, if there is less water, spinach plants will also be underdeveloped, the leaf mechanism is senescent, and the quality is very easy to sprout. In addition to the particularly hot summer, it is very good to plant spinach in autumn, spring and winter, and the actual planting can be planted and managed according to the regional climateLike now in October, it is suitable to plant spinach, the key to management methods is to pay more attention to sprinkling, fertilizer, if some areas in the southern region are in broad daylight or very sunny, it must be shaded and sunscreened.

From October to around November. Prepare the seeds in advance, dry the seeds, soak them in water to promote germination, choose the soil with fertile soil and strong drainage, sow it evenly on the soil surface, cover it with a thin layer of soil, and pour in the appropriate amount of water.

The temperature conditions in different regions are different, and the ripening cycle of different spinach varieties is also different, so the planting time should be determined according to the characteristics of the spinach variety and the climate and environmental conditions of the planting area. Autumn spinach is generally planted at the same time.

August-September. Spinach Cultivation Techniques:

1.Soak seeds in water. Clean the seeds first, soak them in clean water for 3-5 days, and sow them when the seeds grow shoots.

2.Sowing seeds and raising seedlings. The sowing method of spinach is generally sown, and the seeds are sown after the furrow surface is fully watered. 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.

3.Breed selection. There are two main varieties of spinach, round leaves and pointed leaves, and you can choose the ones with strong cold tolerance or heat resistance according to the climate.

4.Field management. When spinach seedlings grow true leaves, seedlings need to be thinned, and weeding can be carried out at the same time.
