What do you know about which varieties to choose when growing spinach?

To choose 1 2-year-old new seeds, choose hardy, large leaves, high yield, ***, high survival rate, such varieties are very suitable for planting, and the quality is very good.

It is best to choose drought-tolerant and high-temperature tolerant, but also to choose leaf hypertrophy, but also to choose varieties of relatively good varieties, but also to choose cold-tolerant, to choose strong winter.

The beginning of autumn is a good season for planting spinach, put on a little farm fertilizer, turn the ground, the ground should be leveled, the seeds are planted, covered with soil, the soil should be kept moist, spinach will emerge in a week or so, but the actual nutrition is still relatively rich, which is rich in vitamins, and is even called "nutrition model student". Moreover, spinach grows fast and has a strong adaptability to the soil environment, so it is a good time to plant autumn spinach after the beginning of autumn. Select the variety.

The selection of good varieties is the most important thing for high yield of rapeseed, and the required variety is to have high yield.

Premium ("Double low", high oil content, etc.), high resistance (lodging resistance, antibacterial resistance to sclerotinia and other characteristics) and other characteristics of high-yielding varieties in the field to choose an open place, with a small pickaxe to turn the land over, so that the soil is soft, in order to facilitate spinach unearthing and growth. Then put the top layer of soil to the side and leave the cover soil, recently it has rained a lot without watering, the land is moist, and the spinach seeds are sprinkled directly on the ground.

Choose an open area in the field and turn the land over with a small pickaxe to make the soil soft so that the spinach can be unearthed and grow. Then put a layer of soil on the side to leave the cover soil, the recent rain does not need to water, the land is moist, directly sprinkle the spinach seeds on the ground on the spinach cold, the temperature is more than 25 degrees is not suitable for its growth, now the beginning of autumn is only a week, this year's beginning of autumn is just at the end of the dog days, after the beginning of autumn did not usher in the expected cool weather, but hotter than before, this is what people often say "autumn tiger".

Autumn spinach is generally sown in early August and harvested from October to November, with a yield of about 2,000 kg per mu. The sowing date can be flexibly grasped according to the local climate and soil fertility, and if the sowing is too early, the plant is prone to overgrowth and premature aging; Sowing too late and the plant is not large enough, spinach is a hardy vegetable and is also heat tolerant. It can be grown all year round.

Because there are more varieties of spinach, but for farmers, there are fewer summer spinach planted, and most of them are planted with spring spinach, autumn spinach and overwintering spinach.

Spinach in autumn should be controlled at room temperature, can be planted in greenhouses, and the autumn climate is dry, spinach is easy to lack water, so do a good job of hydration, and water spinach a lot every day.

When planting, it should be planted thicker and covered with mulch, so that the spinach will grow quickly and will not be frozen to death because of the cold weather.

The planting time is usually around August every year, and after about 1-2 months, it can be harvested in September and October. It can be planted in deep, draining and air permeable soil, and the soil is leveled and raked in advance, and fertilizer is applied. Select a good variety, do a good job of germination treatment in advance, sow the seeds into the soil, water in time to keep the soil moist, and the seedlings can emerge neatly in about a week or so, and pay attention to water and fertilizer management after planting.

It is better to plant it intensively, because intensive cultivation of spinach can increase yields and also bring profits.

1. Common types and varieties of spinach. According to the shape of spinach leaves and the presence or absence of spines on the fruit, spinach can be divided into pointed leaves (thorny) and round leaves (thornless) types.

2. Beijing spinach. Beijing landraces. The leaves are arrow-shaped, with a pair of deeply lobed lobes at the base, the green is slightly thinner to the flesh, less fiber, and the quality is better.

The fruit is diamond-shaped and has thorns. Cold-tolerant, not heat-resistant, with a yield of 1000 2500 kg per mu, suitable for root stubble overwintering and autumn cultivation.

3. Japanese large-leaf spinach. The leaves are elliptic to ovate, slightly pointed at the apex, and shallowly notched at the base. The leaves are broad, thick, and dark green. It has strong heat resistance, is not cold tolerant, and is suitable for summer and autumn cultivation. High yield and good quality.

4. Spinach with large round leaves. Introduced from the United States, it is a spineless species. The leaves are ovate to broadly triangular, the leaves are hypertrophied, the leaf surface is wrinkled, and the color is dark green.

The quality is sweet and tender, late in spring, high yield, good quality, but not cold-tolerant, and the weight of a single plant is kilograms. The disadvantage is that the ability to resist downy mildew and viral diseases is weak. It is cultivated in Northeast China, North China, and Northwest China.

It can be planted in March, in May, in July, or in September. It is planted in October. It can be sown in the form of crop rotation, sowing by manual sowing, or by machine sowing, and some seeds with a relatively high survival rate should be selected, and fertilization management should be carried out.

If it is autumn spinach, then it is better to plant it in August and September every year, the soil must be very fertile, the pH should be appropriate, the temperature should be suitable, more watering and more fertilization, and do a good job of insect and pest control measures.

It can be planted at any time of the year, for example, in March, in May and July, and in August and September. It can be sown by machine, and it can also be sown when the temperature is more suitable, choose some better varieties, and choose some survival resistant varieties, when planting, you need to soak the seeds in water first, and then put them in the refrigerator, and finally plant them in the soil.

Spinach is a highly adaptable crop with a high level of low temperature tolerance and seed germinationThe most suitable environmental temperature for growth and development is between 15 degrees and 20 degrees, when the ambient temperature is higher than 25 degrees, the cabbage is very prone to abnormal development, especially in the summer, the ambient temperature is high, the sunshine is obvious, it is very likely to bloom and its sprouts, which endangers the taste and loses the meaning of the product itself. The main stem of the spinach is relatively developed, thicker, and the upper end is dark purple, which is edible. The leaves are halberd-shaped or oval, thick emerald green, with long stems, and the leaves are a key part of the consumption.

The leaves are born on short stems and can produce more heading. The stems are hollow, and the young stems before blooming are also edible. Porphylla blooms in spring, dioecious, generally the proportion of female and male plants is the same, but there are also monoecious, and there are small pure male plants and large nutrient male plants in the male plants.

Wind flower, the fruit is a polymer fruit, also known as a cell fruit, each fruit contains a seed. Generally, the seeds are actually fruits, and the seed coat is leather, and water and gas are not easy to permeable. There are spiny and non-spiny species.

Generally, there are spiny seed leaves that are halberd-shaped, and the production machine is sharp, and it is also called sharp leaf species. Its leaves are thin and resistant to high temperatures, mature early, easy to sprout, and suitable for early autumn planting. The leaves of thornless species are oval, and the production machine is relatively round, which is also called round-leaved species.

Its perfection is late, it is not easy to sprout, the leaves are large and thick, ***, suitable for residual flowers or spring planting. Spinach is dominated by autumn planting, can be planted from 8 to 11 months, sown early, 30 to 40 talents after sowing, and can be harvested until the next spring before sprouting. Spring ploughing is suitable for late March, and it is obtained 30-50 days after sowing.

You can sow dry seeds immediately, and you can also soak the seeds in cold water for about 20-30 minutes before starting to promote teeth. Before announcing planting, we should water the bottom water, gently comb the subsoil after sowing, so that the seeds can fall into the soil cracks, and cover with wheat straw to keep the soil layer moist enough to facilitate the excavation of seeds. After 5 planting, we need to keep the soil moist from time to time, and the seedlings can be ready after about a week.

Due to the relative heat and drought in autumn, the growth and development of the seedlings are weak, and the seedlings are often fallen, so the amount of seeds should be large.

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 cold and drought tolerant, that is, it is not waterlogging, so when choosing a plot, it is necessary to choose a plot with good drainage and irrigation conditions, spinach taproot into the soil deeply, too much watering and too high moisture, will inhibit root respiration, easy to cause root rot, so watering should be appropriate at the right time, spinach is a relatively cold-resistant green leafy vegetable, more suitable for planting in spring and autumn, spinach seeds can also germinate at 4, but the temperature suitable for seed germination and growth is generally about 15 20.

Spinach grows with light requirements. 3 words "not strict", spinach planting is mostly the use of intercropping mode, if the summer temperature and light time are very long, then the occurrence of sprouting phenomenon is inevitable. Spinach is a long-day crop, under high temperature and long-day conditions, the plant is easy to moss and flower, the sunshine intensity is not strict, and its growth habit is more suitable for planting in our north, so the planting of spinach is still very common in the north.

Spinach grows most vigorously under the environmental conditions of 80% to 90% air humidity and 70% 80% soil moisture, with thick leaves, good quality and high yield. Spinach needs a lot of water in the growth process, lack of water during the growth period, slow down growth, mesophyll aging spinach germination after the growth of seedlings is relatively fast, because the temperature is relatively high, so it should be watered and fertilized in time according to the soil moisture. It is best to spray a blocking herbicide once when planting spinach.

For the land where spinach is grown, it is necessary to choose the plot where the soil acid and alkali are neutral, the water permeability and air permeability are good, the soil should be fertile, the farmer's bottom fertilizer should be applied, the drainage should be good, and the plot should be sown without waterlogging or drought. Spinach planted in autumn should choose rapeseed suitable for planting in autumn, and it is necessary to pay attention to it when buying, autumn spinach varieties are highly tolerant, fast-growing, and harvested early, which must be noted. Try to choose round-leaf spinach seeds with good taste and good resistance, of course, sharp-leaf spinach can also be, it is important to choose varieties according to personal taste, from the market sales point of view, round-leaf spinach is more popular, the key is to eat the right taste.

Spinach prefers mild climatic conditions and is particularly resistant to low temperatures. Seeds germinate at 4 o'clock, so they can be sown in northern areas just after the soil has thawed. The appropriate temperature for germination is 15 20, spinach plants can grow well above 10, and the most suitable temperature for vegetative growth is about 20

Spinach is very good to survive, basically just sprinkle the seeds. Spinach is very cold-tolerant, it can germinate at a minimum temperature of 4 °, and the requirements for sunlight intensity are not high; Spinach is highly adaptable to the soil, making it ideal for northern cultivation.

Spinach seeds germinate at 4 years old, at 15-20 years old the best for seed growth, growing spinach is best to let the sun shine for a long time. Spinach has a high water requirement. The soil in which spinach is grown should be neutral, which can be alkaline, but not acidic.

Spinach loves sunlight and should be planted in a sunny and well-hydrated place so that the spinach will grow well and will grow taller more easily and the leaves will grow fuller.

How to grow spinach? The rural guy will explain in detail for everyone, have you learned after listening to the rural agriculture farmer, rural affairs rural entrepreneurship story rural interesting facts rural life rural old people farmers get rich farmers' joys and sorrows rural farmers rural aunt uncle uncle boy child aunt.

Spinach is one of the most cold-tolerant vegetables in the green leafy vegetables, which can overwinter in the open field in the south of the Yangtze River Basin, and can safely overwinter in the open field in areas of about -10 degrees, and can overwinter in the open field with wind barriers and ground cover in North China, Northeast and Northwest. The cold tolerance of spinach is closely related to plant growth and development and seedling age.

Spring spinach can be sown when the temperature rises to more than 5 °C after the beginning of spring, March is the appropriate period for sowing, summer spinach is sown in stages from May to July, autumn spinach is sown in August to September, and overwintering spinach is sown in mid-October to early November. The spinach cultivation techniques are as follows:

Prepare the land for furrowing. Choose loose and fertile, water and fertilizer retention, good drainage and irrigation conditions, slightly acidic loam with good pH value. 4000 kg of decomposed organic fertilizer per mu of land preparation, 40 kg of superphosphate, leveling fine, winter and spring should be done high furrow, summer and autumn should be done flat furrow, furrow width meter.

Sowing seeds and raising seedlings. Spinach plots are generally sown. Summer and autumn sowing is to soak the seeds in water for 12 hours one week before sowing, put them in a well or in a refrigerator or refrigerator at about 4 °C for 24 hours, and then promote germination at 20-25 °C, and sow seeds after 3-5 days of germination. Dry or wet seeds can be sown in winter and spring.

Kilograms of sowing per mu.

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. Frequently 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.

Field management. 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.

After the emergence of summer spinach, it is still necessary to cover the shade net, cover the shade in the sun, 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.
