How to sow spinach and what is the best way to sow spinach?

The sowing method of spinach is:Seed selection: Seeds that are full and adaptable to the local environment should be selected for spinach, and the seeds should be sterilized before planting.

Plots: To plant spinach, you need to choose a plot with a deep soil, loose soil and sunny tench, and the soil needs to be deeply cultivated for 20 to 30 cm before planting.

Spinach has strong cold tolerance, seeds can also germinate in the environment of 4, the temperature needs to be controlled between 15 and 20 during the growth period, when the outside temperature is higher than 25, the plant grows poorly, and cooling measures need to be taken.

Spinach is also called pineapple, Persian grass, red root cabbage, parrot cabbage, in the vast countryside of our country can be planted all year round, because its management is relatively simple and easy to grow, so, people's table is an indispensable common dish.

1. Spinach growth habits.

The growth habit of spinach is to be afraid of heat, like cold and cool climate, relatively cold-resistant, can resist low temperatures of minus 8 degrees, the most suitable temperature is about 20 degrees, and the low temperature requirements are not strict in spring, and the characteristics are that the sunshine is sufficient and the most suitable for growth. In spring and summer, with the enhancement of temperature and sunshine, it is easy to sprout and bloom early, so in addition to high temperature summer, it can be cultivated all year round, and it can also be overwintered in the open field, and green spinach can be eaten early in the next spring.

2. Planting technology.

Cultivation management spinach taproot is red and developed, the planting soil layer should be selected deep point, and before planting the soil should be deeply turned over about 20 30 cm, for the northern soil is too acidic, quicklime should be sprinkled for soil disinfection. Spinach seeds have a hard peel and are not easy to breathe, so they must be soaked and germinated before planting. The method is to soak the seeds in warm water for 24 hours 5 7 days before sowing, take out the seeds to protect the temperature and stack them for germination for 5 6 days before sowing, or mix germination in the sand and cover them with plastic film, this method is relatively rapid.

Spinach grows slowly in the early stage, the amount of fertilizer required is relatively small, and the top dressing should be applied diligently, generally with 20% of human urine every 4 6 days. Try to keep the soil moisture suitable, and pay attention not to fertilize the soil when it is too wet. In the middle and late stages of spinach growth, the rhizome is developed, the amount of fertilizer required increases, and the temperature gradually decreases at this time, and the top dressing can be gradually thickened to about 35%.

Late sowing of spinach ready for overwintering should be applied with sufficient fertilizer before spring warms to promote vegetative growth and prevent early sprouting.

In rural areas, most farmers adopt anti-freezing measures for overwintering spinach: sprinkling a layer of grass ash or laying a layer of crop straw before winter, which is conducive to rapid growth and anti-freezing in spring.

3. Nutritional value.

Spinach is relatively nutritious, can be served cold, stir-fried or made into soup, and is one of the main green leafy vegetables. Spinach contains oxalic acid, and eating too much of it affects the body's absorption of calcium. In the north, people love to eat noodles, and spinach noodles are the best delicacy.

In short, spinach farmers have their own set of experience, and the soil must be intensively cultivated to prevent losses caused by continuous planting, so as to ensure a good harvest of planting.

Spinach sowing date selection.

1.Spinach can be sown all year round, but you just need to choose a different variety. Choose high-temperature resistant varieties in the high temperature season, and cold-resistant varieties in winter.

Spinach seeds can germinate at 4 o'clock, the optimal germination temperature is 15 20, the temperature is more than 30, the germination rate is gradually reduced, and it is easy to cause the lack of seedlings and uneven seedlings.

2.Spring spinach is sown in March. During this time, the soil temperature has risen to 4-5 and the seeds can germinate slowly. In order to harvest early, it can be cultivated by mulching small arches, etc., and the sowing date can also be about 20 days earlier.

3.Summer spinach is sown between May and July. The temperature during this time period is high, and the high-temperature resistant spinach varieties are selected, and shading measures and sprinkler irrigation measures can be taken to replenish water and cool down when sowing, and the emergence rate is very good.

4.Autumn spinach is sown in August-September. The temperature is the highest during this time period, and the external environment often encounters storms, even rainy and other disaster weather, pay attention to the improvement of drainage and irrigation facilities, and use two-layer shade nets to shade and tarpaulins to prevent rain, and uncover them in the morning and evening to receive sunlight.

5.Winter spinach is sown in October-November. Winter spinach sowing period temperature is low, sowing too late or even can not germinate, early spring only began to unearth, need to cover the winter straw or rotten farmhouse fertilizer to prevent freezing, early spring to strengthen water and fertilizer management, and strive to extend the harvest period, before the harvest of more spinach.

Spinach seed treatment method.

1.Spinach seed life and service life. The service life of spinach is relatively long, generally 5-6 years, but the germination rate and germination potential are reduced year by year, under normal circumstances, only 1-2 years of new seeds are used for sowing, and the seeds of the third year can be used in special circumstances, but it is necessary to do a germination test in advance, and determine the amount of sowing according to the germination experiment.

After sowing, get some hay and dead leaves as mulch, and water it on the mulch to create an excellent small environment for germination.

We can plant flowers in our community, and we can grow vegetablesAfter soaking the spinach seeds in water, they are placed in the refrigerator for 2 days, and the seedling emergence rate is high.

My spinach was soaked for a day and a night, and it was several days earlier than the non-soaked spinach.

How to grow spinach: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. In order to ensure the yield, sow about per mu, water once after sowing, cover the soil 2-3cm, keep the soil moist, and the seedlings can be planted in about a week.

2. Field management

Spinach has strong growth ability, as long as it emerges, it can 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 weeded in time at the same time. Grow 3-4 true leaves can be watered with thin fertilizer once, and should not be too thick when fertilizing, so as not to cause root burning and death due to excessive fertility.

Spinach, the name of traditional Chinese medicine. Spinacia oleracea L. for the genus Spinach in the Chenopodaceae familyof the whole grass.

Native to Iran, it is widely cultivated throughout our country. It has the effect of detoxifying fever, clearing blood and veins, and benefiting the stomach and intestines. It is often used for imitation blind headache, dizziness, redness, night blindness, thirst, constipation, hemorrhoids.

1. Sow seeds and raise seedlingsWhen planting spinach, you can use the way of sowing to plant, in the week before sowing, you can soak its seeds in water for 12 hours, and then put it in the refrigerator for 24 hours, take it out and put it in a warm environment to germinate, after three to five days the spinach seeds can germinate, and then directly sow it.

2. Field managementSpinach planting after the field management is also very important, after it grows true leaves to be watered in a timely manner, and so spinach grows from a piece of true leaves can be combined with seedlings weeding and timely weeding, top dressing should comply with the first light and then thick, usually should be applied to the farmer's wide hall loss of fertilizer, in it carefully grows to more than ten centimeters after the urea can be topdressed, five to fifteen kilograms per mu.

There are five things you need to pay attention to when growing spinach: planting time, planting soil, variety selection, seed treatment and ridge, and water and fertilizer management.

Planting time

Generally speaking, spinach can be planted all year round, and spring spinach is generally planted at a temperature of 5 or more, and March is the best sowing period every year.

Planting 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.

Breed 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.

Seed treatment

Spinach is generally sown by seeding. When sowing seeds in summer and autumn, soak the seeds in water for more than 12 hours a week before sowing, then store them in a place with an ambient temperature of only 4 for 24 hours, and then go to an environment where the temperature is 20 25 for germination.

Water and fertilizer management

After sowing, you can water a little, remember not to water too much. The sowing in summer and autumn should be covered with straw or shade nets, so as not to affect the development of seed infiltration due to the intensity of the sun, and keep the soil warm and moist.

Spinach seeds need to be soaked, germinated, and then sown on the soil surface before being sown.

When planting spinach seeds, you need to choose seeds that are full and intact and undamaged, and then soak the spinach seeds in cold water for 24 hours to absorb enough water, and then place the spinach seeds in an environment with a temperature of 20-25 degrees for germination, wait for about 4-6 days, and the spinach seeds will be white.

When planting spinach, you need to apply nitrogen, phosphorus and potassium compound fertilizer and organic fertilizer to the soil before sowing to make the soil more fertile, and then spread the spinach seeds evenly on the soil surface, and then cover the soil with a layer of plant ash to provide the nutrients needed for the growth of spinach, and water the soil once.

Shade measures for spinach

In the summer, when Yefeng sows and breeds spinach, it is necessary to build a shade net on the soil surface to shield the spinach from the sun, avoid it from sunburn, and make the plant grow normally, and if you sow and propagate spinach in autumn, you need to cover the soil surface with a layer of plastic film or straw to keep the spinach warm and moisturize, so that it can emerge quickly.

Conservation management of spinach

When maintaining spinach, it is necessary to carry out a top dressing for the plant when the plant grows 1-2 true leaves, and you can use the farmhouse fertilizer after ripening to promote the vigorous growth of spinach, and during the vigorous growth period of spinach, you need to apply urea and organic fertilizer every other month to make the spinach mature quickly.

Spinach seeds can be prepared for planting all year round, in the spring is generally carried out after the beginning of spring, when the temperature reaches 5 degrees chain, it can be sown, relatively speaking, March is more suitable, summer usually imitation branches are sown between May and July, and autumn is in August and September, and winter is sown in October and November.

1. Prepare the land to make furrows: When spinach is planted, it is necessary to choose loose and fertile, water and fertilizer retention, and convenient drainage and irrigation, and in order to improve the fertility of the soil, it is necessary to apply sufficient base fertilizer when preparing the land, organic fertilizer can be used, and it is also necessary to level and make furrows after fertilization.

2. Seed selection and germination: If it is sown in spring or autumn, the seeds need to be processed in advance, and the seeds need to be soaked in a week before sowing, and taken out and put in the refrigerator after 12 hours, and the temperature is kept at about 4 degrees, and then placed in the environment of about 20 degrees after 24 hours to promote germination.

3. Sowing seedlings: After the spinach seeds germinate, they can be sprinkled on the surface of the soil, and they need to be watered with enough water before sowing, and the surface of the soil should be lightly raked, and the seeds need to be covered with a layer of plant ash after they are buried.

1. When choosing varieties, it is necessary to choose varieties that are heat-resistant and easy to germinate, and also choose slightly acidic soil with fertile soil and strong water retention capacity before planting, apply foot fertilizer for deep turning, and make a flat furrow of 1.8 meters in the soil, water the bottom of the foot before planting, and use shade nets to moisturize.

Soak the seeds for about 18 hours before planting, then start germination in a cool place indoors, turn the seeds frequently and keep them moist, and after about a week of germination, you can start sowing.

It is prone to diseases such as anthracnose, downy mildew and other leaf-based diseases when planting. Pests are generally aphids, and leaf miners are treated with drugs in a timely manner.

To carry out a reasonable rotation for about three years of scientific rent code irrigation, scientific fertilization can be used 500 times of 64% alum, or 700 times of 70% methyl tobuzin solution for spray control, if insect pests, you can choose 3500 times of 75% latent grams, or use 1800 times of 15% Caixi and other drugs for control.

Spinach should be harvested scientifically after planting, and it can be harvested about 30 days after sowing, and then harvested every 20 days or so.
