How to grow spinach to produce good, how to grow spinach?

Spinach growth habits. Spinach is a cold-tolerant vegetable that grows at a temperature of 15 to 20 degrees Celsius and can withstand temperatures as low as -6 to 8 degrees Celsius. The light requirements are not high, and sufficient water is required, and the growth of spinach will be affected under high temperature and long sun conditions.

Spinach has a high adaptability to the soil and grows well in fertile soils with strong water and fertilizer retention capacity.

Spinach planting time. Spinach is highly adaptable and can be grown all year round, generally by sowing seeds. According to the sowing time, it can be divided into spring spinach, summer spinach, autumn spinach and winter spinach, spring spinach is sown in March, summer spinach is in May to July, autumn spinach is from August to September, and winter spinach is from October to November.

Spinach seed selection and germination. There are many varieties of spinach, but it is necessary to choose the right varieties according to their own region, generally choose high-quality varieties that are resistant to high temperature, drought and disease, and choose varieties according to the planting season, which need to be cold-tolerant in winter and water-resistant in autumn. Spinach does not need to be germinated in spring, but it must be germinated in summer and autumn, which can shorten the growth period and increase the germination rate of seeds.

Generally, the seeds are soaked in warm water for a day, and then germinated at room temperature, and they can all germinate in four to five days. 

Spinach management and fertilization. Temperature plays a key role in whether spinach can grow normally, so we need to observe the growth temperature of spinach at all times, generally keeping it at 15 to 25 degrees is the most appropriate, below 5 and above 30 degrees are not conducive to the growth of spinach, which may lead to low variables and quality. Spinach is a leaf-eating vegetable, in order to promote the growth of spinach, urea or manure and urine water are mainly used for top dressing, so that the spinach grown is tender and large. 

Spinach is planted in late March in early spring, and slightly acidic soil with sufficient nutrients and convenient drainage of spinach roots is selected. Soak the seeds in warm water for 10 hours, then refrigerate them in the refrigerator before taking them out for germination. The treated seeds are sown in strips, and the seedlings will emerge after a week.

1. Planting time.

The planting time of spinach is generally in early spring, and when the weather temperature rises to more than 7, the soil can be planted after thawing; Late March is the best time to sow seeds; Spinach is generally planted around June in summer, spinach is generally planted around the end of September in autumn, and spinach is planted around the end of October in winter.

2. Plant soil.

In the spinach planting method, it is also necessary to prepare suitable soil, try to choose a slightly acidic soil with sufficient nutrients and convenient spinach root drainage, the soil pH should be controlled between 5, and an acre of land before sowing is buried in the soil with 3000 kg of farm fertilizer, which can improve the germination rate of seeds.

3. Seed treatment.

Generally, the method of strip sowing is used to sow seeds, put the selected seeds in warm water at 35 for 10 hours, then put them in the refrigerator for 5 hours, or put them in the refrigerated freezer for 7 hours, take it out and put it in the temperature of about 22 for germination treatment, and wait for the growth of fine tender tips can be sown.

4. Sow seeds.

About 4 kg of seeds are sown in one acre of land, dry seeds are recommended in spring, and wet seeds are recommended in other seasons; After sowing in summer or autumn, it is necessary to use a shade net or cover the soil with a layer of dry straw, which can effectively resist the direct sunlight and high temperature, and the seedlings can emerge after a week, and the temperature is low in winter, so it is necessary to cover the soil with a breathable film, and the seedlings can emerge after 10 days.

1.Spinach has a thicker root system and easily absorbs water. It has high requirements for soil, and usually uses high-quality soil with good drainage capacity.

2.Spinach is usually sown and the seeds should be soaked in water for 12 hours one week before planting.

3.Remember to sprinkle a layer of plant ash after sowing. Spinach grows relatively fast and usually germinates in about seven days after the seeds.

Spinach (spinaciaoleraceal.)Also known as Persian vegetables, red root vegetables, parrot vegetables, etc., it belongs to the genus Spinach in the Chenopinaceae family, 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.

1. Soil.

The roots of spinach are relatively thick, can penetrate deep into the soil, and absorb water relatively strongly. The requirements for soil are relatively high, and it is generally necessary to choose soil with good drainage and sufficient nutrients. You can add some coarse sand and the like to the soil, which can increase the air permeability of the soil and promote the rooting of seeds.

2. Sowing. When spinach is sown in summer and autumn, soak the seeds in water for more than 12 hours a week in advance, then store them in the environment of 4 for 24 hours, and then put them in the temperature environment of 20 25 to germinate, and wait until the seeds germinate before sowing. Spinach in spring and winter can be sown directly without the preparation mentioned above.

3. Shade and hydrate.

After sowing, be sure to keep the soil warm and moist, but be careful not to water too much. Spinach in summer and autumn needs proper shade to avoid strong light exposure affecting seed development. Spinach planted in spring and winter is generally covered with plastic film to maintain the temperature and promote the growth and development of the seeds.

Fourth, fertilization. Spinach grows at a fast rate and generally sprouts about seven days after sowing. When the true leaves are grown, you can add a clean manure water to provide the nutrients needed for growth, and you generally need to apply thin fertilizer at the beginning, and then you can use a little more. Spinach can generally be applied with well-rotted farmhouse fertilizer, and urea can be applied once after it grows to more than ten centimeters.

Growing environment

Temperature spinach is a cold-tolerant vegetable, the seeds can germinate at 4, 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.

Sunshine spinach is a long-day crop, 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.

Moisture spinach leaves have a large leaf area, soft 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 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.

It is easier to grow spinach in acidic soil with a high nutrient level.

Spinach has a well-developed root system and has a high demand for soil and water during cultivation. It is necessary to choose acidic soil with fertile soil, good air permeability and high nutrient degree to promote the germination rate of spinach. Depending on the temperature, you can choose a variety that is resistant to heat or cold, which is convenient for the yield and quality of spinach.

When planting spinach, you can put the seeds at 4 low temperatures, or you can put them in the environment of 18-25 to take root and sprout, when spinach grows 2-3 leaves, it is necessary to fertilize in time to ensure sufficient nutrients and promote the growth and development of spinach. Spinach is a cold-tolerant crop, the most suitable growth temperature is 15-20, in the process of planting spinach, the temperature should not be too high, and the shade treatment should be taken in time to prevent the spinach leaves from being burned by strong light.

Spinach is an annual herb that is smooth, tender and moist. The young roots are reddish. The leaves are alternate, the basal leaves and the lower leaves of the stem are larger, the upper leaves of the stem gradually become smaller, halberd-shaped or triangular-ovate, and the leaves on the inflorescence become lanceolate with long stalks.

Flowers unisexual, dioecious, male flowers arranged in spike-like inflorescences, apical or axillary, perianth 4, yellow-green, stamens 4, extended, female flowers in clusters in leaf axils, perianth jar-shaped, with 2 teeth, columella 4, linear, elongated, lower combined. Cellular, hard, usually with 2 horned spines. Flowering period in summer.

When planting spinach, it is necessary to choose acidic soil with a high degree of nutrients, and turn the soil regularly to ensure that it has air permeability and moisture, and enhance the survival rate of spinach. Germinated seeds can be placed directly into the soil when planting, or spinach seeds can be sprinkled directly into the soil. It is necessary to pay attention to pruning branches and leaves in time to prevent the loss of nutrients and water, and have a certain space for development to make them grow vigorously.

<>Growing spinach is not difficult for many people, and you can learn it by looking at the tutorial. So, do you know how to grow spinach well and quickly?

1. If you want to plant spinach to produce well and quickly, the first thing is to observe the growth habits of the spinach you grow. The living habits of spinach are roughly the same as that of cabbage, which is relatively cold-tolerant, and if it is grown in the north, it does not need to invest a lot of time in the care of spinach. The planting choice of spinach can be about 15, the light intensity is moderate, and it is reasonable to ensure that the light time of several hours a day is reasonable, but it is necessary to pay attention not to expose to the sun for a long time, and the long-term exposure will make the leaves of spinach develop poorly and are easy to wither yellow.

2. The cultivation of spinach requires fertile and flat soil, and at the same time, it is necessary to pay attention to daily irrigation, and water is also very important for the growth of spinach. Before the seeds are buried, the soil should be watered to keep enough moisture in the soil, and it is most reasonable for the soil to meet the standards of wet clay and no muck. Because the summer in the south is relatively hot, spinach is easy to be exposed to the sun and die easily under high temperatures, so it is necessary to cover the surface of spinach with a film to keep its moisture and make it not easy to dissipate.

3. As long as the spinach planted according to the requirements can basically survive, but if you want to produce a higher yield in a certain area, you must strictly follow the scientific method in the planting method. Sorting spinach is the first step, and the seeds are selected according to the local climate and the amount of rain in the second half of the year. Then the soil is turned over to keep the soil moist and soft, so that the spinach can develop and grow rapidly after sowing.

It should be noted that a certain amount of fertilizer should be added at the same time when turning the soil, so that the soil can be combined with fertilizer at the initial stage, which can increase the fertility of the soil.

4. After a season of spinach planting, it is necessary to implement scientific management, the management mentioned here is mainly for large-scale spinach planting, if the temperature is too high, it is necessary to use the breathable mesh cloth of the black grip Pansen for shading, remember not to directly cover the surface of spinach, to use a pole to prop up, the effect of this is to avoid the cover to crush the sprouts that have just grown out of spinach. Every week, we should do a good job of spinach management records, scientifically understand each process of spinach growth in stages, prepare in advance for the prevention of pests and diseases, and spray diluted pesticides in time when a small number of spinach leaves are found to have insect pests.

Keep the above 4 points in mind during the planting process, and you will find that every spinach is of excellent quality at the time of harvest.

How to grow spinach:

1. Planting time.

Generally speaking, spinach can be planted all year round, and the planting of spring spinach generally has to reach a temperature of 5 or more, and March is the best 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.

2. Plant soil.

In general, it is 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. Variety selection.

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 treatment.

Spinach is generally sown by seeding. 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 4 for 24 hours, and then germinated at a temperature of 20 25 for germination, and then the seeds can be sown after germination. Spinach in spring and winter does not need to go through these treatments and can be sown directly.

After sowing, remember to sprinkle a layer of plant ash.

5. Water and fertilizer management.

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.

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.
