When is spinach grown in the Northeast? When is winter root spinach planted in the northeast zone

Autumn spinach is generally planted from August to October.

Spinach cultivation techniques.

Seeding time. Spring spinach can be sown when the temperature rises above 5 °C after the beginning of spring, March is the appropriate time for sowing, summer spinach is sown in stages from May to July, autumn spinach is sown from August to September, and overwintering spinach is sown from mid-October to early November. Spinach usually germinates in 2 to 3 days after sowing.

Prepare the land for furrowing. Choose loose and fertile, water and fertilizer retention, and good drainage and irrigation conditions. 4000 kg of decomposed organic fertilizer and superphosphate are applied per mu during land preparation.

40 kg, leveling and fine, winter and spring should be done high furrow, summer and autumn should be flat, furrow width to meters.

Sowing seeds and raising seedlings. Spinach plots are generally sown. Summer and autumn sowing is to soak the seeds in water for 12 hours 1 week before sowing, put them in a well or in a refrigerator or refrigerator for about 4 hours for 24 hours, and then promote germination under conditions of 20 to 25, and sow seeds after germination in 3 to 5 days.

Dry or wet seeds can be sown in winter and spring. 3 to kg per mu are sown.

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 to 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. Autumn spinach produces real leaves.

After pouring 1 time of farm manure water; After 2 true leaves, combine seedlings, weeding, top dressing first light and then thick, and apply more farm fertilizer and water in the early stage; Top dressing 2 to 3 times during the peak growth period, urea per mu each time.

5 to 10 kg.

The soil remains moist after winter spinach planting. When there are 3 to 4 true leaves, the water should be controlled properly to facilitate overwintering. For 2 to 3 true leaves, the seedling spacing is 3 to 4 cm.

According to the seedling condition and weather, water and fertilizer are applied first, and farmhouse fertilizer and water are the mainstay. 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 farm fertilizer and water to prevent early sprouts.

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 fertilization water, in the early stage, the farmhouse fertilizer water is applied lightly and diligently, and in the later stage, especially 15 days before harvest, fast-acting nitrogen fertilizer should be applied.

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 light water.

Pour frequently. After 2 to 3 true leaves, fast-acting nitrogen fertilizer is applied twice. Water should be poured after each fertilization application to promote growth.

The growth cycle of spinach is about 35 days in autumn and 45 days in winter and spring.

Hello dear, it's a pleasure to serve you! For your inquiry, spinach in the Northeast is generally planted from late October to early November. The spinach in the Northeast has spring spinach and autumn spinach.

Spring spinach is generally planted in April and May, and can be planted during the Qingming Festival, and autumn spinach can be planted in late July to early August. Spinach can be planted in all seasons during the 40-day growth period, and the temperature is above 5 degrees Celsius.

Good luck [love].

Growing overwintering spinach in the open fields in the north is generally carried out in August and September, and it can be planted from late August. In the north, the temperature drops quickly after the winter, so it is important to plant early. However, the actual planting time should also be adjusted appropriately, and if the climate is still warm, it can be postponed for a few days.

When planting overwintering spinach on land, choose a flat piece of land with loose soil and plough the ground deeply before planting. During the land preparation, some organic fertilizer is also applied, which is beneficial for spinach growth.

Precautions for planting spinach with winter roots.

According to the traditional planting experience, watering frozen water can effectively protect seedlings from frost damage, delay watering back to green water, which is more conducive to the recovery of soil temperature in early spring, and promote the growth of spinach. In between, don't pour frozen water too early.

Spinach is able to adapt to a lot of land, but in the process of choosing the land to be sown. It is best to choose sandy soil, because the sandy soil warms up quickly in early spring, so this can be more conducive to the germination of spinach seeds, and it is conducive to the early harvest of spinach. Clayey soil is actually suitable for growing spinach, so the reason is that it is extremely rich in mineral nutrients and good fertilizer retention, which can effectively improve the yield of spinach.

Autumn spinach is usually planted in autumn, the sowing time of autumn spinach is generally in August, after about 1 2 months, autumn spinach can be harvested in 9 10 months, for the purpose of planting autumn spinach, the growth is very favorable, the temperature is very suitable, the cultivation of spinach has a high yield and good quality. Strip Lai Piercing Head.

Autumn is generally planted in autumn, and autumn sowing time is generally in the month, about a month later, the harvest is in the month. For the purpose of planting autumn, the growth is favorable, the temperature is suitable, and the cultivation yield is of high quality. Diarrhoea.

The temperature of autumn spinach after sowing is about 20 per day, so autumn spinach is the one with the highest yield and the best quality among all stubbles throughout the year. In Northeast China, Inner Mongolia, Xinjiang and other places, the seeds are sown from late July to early August, and harvested from late September to mid-early October.

Planting techniques for autumn spinach:

1. Organize the soil.

Spinach cultivation requires soil and can be planted in deep, well-drained and aerative soil. Determine the planting location in advance, level the soil and rake it finely, and apply fertilizer.

2. Treat the seeds.

There are many varieties of spinach, if you plant early, you can choose round-leaf spinach with high heat tolerance, and if you plant late, you can choose sharp-leaf spinach with strong cold tolerance. The seeds are germinated in advance, soaked in warm water for about 12 hours, and then placed at a temperature of 22 degrees for germination.

3. Sow seeds into the soil.

Before raising seedlings, the furrow surface should be watered sufficiently, the soil should be gently raked, the seeds should be sown into the soil, and then covered with a layer of plant ash. If the light is strong, you can put on a shade net, water in time to keep the soil moist, and the seedlings will emerge neatly in about a week.

Fourth, water and fertilizer management.

After planting, we should pay attention to the management of water and fertilizer, water regularly during the growth period, sprinkle the manure water once after the seedlings grow out of the true leaves, and apply about 3 times of Trim water-soluble fertilizer during the peak growth period.

Autumn spinach in the Northeast is planted in early September, at this time you can sow autumn spinach, after sowing it begins to sprout, grow seedlings, grow to a certain size, can overwinter in winter, and continue to grow in the next spring.

Autumn spinach planting time in Northeast China, around August 1st, you can sow autumn spinach, you can sow stubble, sow another stubble on August 10th, and sow another stubble on August 20th, so that you can harvest continuously.

Autumn spinach is a spinach that is sown in summer or early fall and harvested in autumn. After the autumn spinach is planted, the temperature is in the period when the average daily temperature is around 20 degrees. In the Tohoku region, it is sown from late July to early August and harvested from late September to mid-October.

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 watershed is sown in August-September and harvested in batches 30 to 40 days after sowing.

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.

<>1, trillion ruined spinach can be planted all year round, spring spinach in the spring after the temperature rises to more than 5 °C when the bridge can start to sow, March is the appropriate period for sowing, summer spinach in May to July phased sowing, autumn spinach in August to September sowing, overwintering spinach in mid-October - early November sowing.

2. Spinach is a cold-tolerant vegetable, the seeds can germinate at 4 o'clock, the most suitable is 15-20, the suitable temperature 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.

3. Yutan spinach is a long-day crop, which is easy to moss and flowering under high temperature and long-day conditions, and has low requirements for sunshine intensity, and can be intercropped with high-stem crops.

4. Spinach leaves have a large 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.

Spinach can be grown all year round.

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 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 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.

Seedlings of spinach

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.

Post-management of growing spinach

Remove the weeds in time, properly spread the seedlings after 2 true leaves, and apply a well-rotted organic fertilizer. When topdressing, the concentration gradually increases, and light fertilizer is applied first. Water in time after fertilization.

Usually according to the climate conditions to water, rainy days in time to remove stagnant water. Winter planting should replenish water, do a good job of heat preservation measures, and avoid frostbite.
