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.

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.

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. Soaking 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 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. Variety 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:

1) Seedling removal When the seedlings grow 2 true leaves, the seedlings that are too dense should be pulled out intermittently, combined with weeding.

2) When shading the seedling stage with high temperature and strong light, cover the shade net from 10 a.m. to 5 p.m.

1. Planting time.

Autumn spinach is spinach planted in autumn, the planting time is generally around August each year, after the beginning of autumn each year, the temperature gradually decreases, the light time is shortened, the natural environment at this time is beneficial to the growth of spinach, can promote the growth of spinach, but also improve the quality of spinach. It is about 1-2 months after planting, and it can be harvested in September and October.

2. 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.

3. 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.

Fourth, 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.

5. Water and fertilizer management.

After planting, we should pay attention to water and fertilizer management, water regularly during the growth period, splash manure water once after the seedlings grow true leaves, and top dressing about 3 times during the peak growth period.

The beginning of autumn has passed, when to plant autumn spinach after the beginning of autumn, and what should I pay attention to before planting?

Autumn spinach is generally sown in August and September, and it can be harvested in a few months.

Variety selection: early sowing, because the temperature is still relatively high, you can choose more heat-resistant round-leaf spinach varieties; When the sowing date is late, you can choose round-leaf spinach varieties or sharp-leaf spinach varieties.

Sowing date: The sowing date of autumn spinach is not very strict, especially in North China (Beijing, Tianjin, Hebei, Shandong, Henan and other provinces and cities and the northern regions of Jiangsu and Anhui), the middle and lower reaches of the Yangtze River and some areas in the northwest, from early August to late August. Since there is no problem with early sprouting, they can be harvested from mid to late September to November.

Seed treatment: when sowing in August, the average daily temperature is still high for the germination of spinach seeds, especially when sowing in early August, the average daily temperature often reaches 24-29, if the sowing is not carried out before sowing, the emergence of seedlings is slow, and the leaf growth period is shortened, which affects the yield. The method of soaking seeds and germination is the same as that of summer spinach.

Soil preparation and sowing: After the harvest of autumn spinach, apply rotting circle manure or human manure as base fertilizer, shallow tillage, rake rake, make flat furrow after leveling, and sow with wet sowing method. When the soil is good, you can take the opportunity to sow the seeds, hoe about 3 cm shallowly, bury the seeds in the soil, and then rake the flat furrow surface, and gently compact when the topsoil is slightly dry.

When the soil is not good, it is not necessary to compact it after sowing, and then irrigate it. After sowing, the temperature of autumn spinach gradually decreases, the emergence rate is higher, and the plant grows rapidly, the individual is larger, and the nutrient area is larger, so the sowing amount per mu can be reduced to kilograms. If the sowing amount is too large, the seedlings grow too densely, and the lower leaves are prone to yellow rot.

Field management: for sowing sowing, when the topsoil is slightly dry, it needs to be lightly watered once to facilitate the emergence of seedlings; If the seeds are sown by the wet sowing method, they generally do not need to be watered before the seedlings emerge. After the seedlings grow 2 true leaves, the growth rate begins to accelerate, so they should be watered frequently and shallowly, and the soil should be kept moist frequently.

After the seedlings have grown 4-5 true leaves, it is the period when the number of leaves and leaf weight increase rapidly at the same time, and the application of fast-acting nitrogen fertilizers (urea, ammonium sulfate, ammonium bicarbonate) with irrigation should begin. Later, according to the growth of the plant, top dressing 1-2 times.

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.

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].

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.

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 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 best time to plant autumn spinach is August.

It can be harvested in batches 30-60 days after planting, and will be put on the market from mid-to-late September to November. At this time, it is characterized by a gradual decrease in temperature, a gradual shortening of sunshine hours, and climatic conditions that are favorable to vegetative growth and unfavorable to reproductive growth, so it is easier to achieve the goal of high yield and high quality.

1. Seed treatment.

When sowing in August, the daily average temperature still has an impact on the germination of spinach seeds, especially when sowing in early August, the average daily temperature often reaches 24-29.

2. Sow seeds at the right time.

Spinach is generally live-streamed, and it is mainly sprinkled. Before sowing, water the bottom water first, gently comb the topsoil after sowing, so that the seeds fall into the soil cracks, and cover with straw or use small arches or tiles to cover the shade net to keep the soil moist to facilitate unearthing, and also prevent high temperature and heavy rain erosion. Keep the soil moist frequently, and the seedlings can be ready after about 6 to 7 days.

3. Cultivation management.

Autumn spinach is in the early stage of high temperature and dry weather, after the growth of true leaves, should be poured with light manure in time, and then with the growth of plants and the temperature decreases, gradually increase the concentration of top dressing. However, it should be applied when the soil surface is dry, if the soil is moist, spinach grows slowly and is prone to disease.

After 2 true leaves, pull out the dense seedlings between the combinations, pull out the weeds, and pay attention to top dressing. Fertilization should pay attention to grasp the principles of light application, diligent application, and first light and then thick.

In the early stage, more organic fertilizer should be applied, that is, decomposed manure, and in the later stage, when entering the peak growth period, the fast-acting nitrogen fertilizer should be applied in stages 2 3 times to promote the growth of leaf clusters, increase yield and improve quality.

4. Harvesting method.

Autumn spinach has a short growing season, so it should be harvested and marketed in a timely manner according to the growth situation and market needs. Generally, when the seedlings are 10 cm high, they begin to be pulled out in batches and put on the market one after another.
