When is overwintering spinach planted, and when is overwintering spinach planted in Liaoning?

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.

Spinach planting time.

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.

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.

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 rotting organic fertilizer per mu is applied to the mu of land preparation, 40 kg of superphosphate, leveling and 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. Generally used to spread. 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 or refrigerator around 4 oC for 24 hours, and then germinate under the condition of 20-25 oC, and sow seeds after germination in 3-5 days.

Dry or wet seeds can be sown in winter and spring. Kilograms of sowing per mu.

Overwintering spinach is sown from mid-October to early November.

Overwintering spinach is generally sown in mid-October to early November, which can ensure that the spinach grows 4-5 true leaves before wintering, and is harvested in batches around the Spring Festival.

Medium and late maturing varieties with strong winter, late budding and strong cold tolerance can be used for planting spinach, such as round-leaved pineapple, late-round-leaf pineapple, Huapeng No. 1, Liaoning round-leaved pineapple, etc.

When planting, we must choose leeward and sunny, loose and fertile soil, good drainage conditions, neutral or slightly acidic soil, and apply 5,000 kg of high-quality decomposed organic fertilizer per mu after cleaning the garden.

25 kg of ternary compound fertilizer, deep ploughing of more than 25cm, and then made into a meter-wide flat furrow.

Spinach seeds germinate slowly, if you want to shorten the emergence period, you can use warm water at 20°C for 12 hours 1 day before sowing, and then remove the seeds to dry for a while before sowing.

Now is the best time to plant, you can go to start planting, water more water at the beginning of planting, ensure humidity to take root and sprout faster.

Overwintering spinach is usually sown between mid-October and early November.

Spinach Cultivation Management:

1.Spinach has certain requirements for soil, suitable for planting in slightly acidic sandy loam soil with fertile soil, loose and breathable, convenient drainage and irrigation, and when ploughing, apply well-rotted organic fertilizer and superphosphate, mix evenly with the soil and level fine, choose to do high furrow or flat furrow according to the planting season.

2.Germination sowing Spinach is usually sown by sowing, seeds need to be soaked in warm water before sowing, put in the refrigerator for 24 hours after fishing, take out and put in the environment at room temperature 20 degrees to germinate, wait for 3-5 days after the epidermis is white and then plant into the soil, cover the soil and water, speed up the germination of seeds.

3.Seedling transplanting After spinach planting, you can spread a layer of grass ash on the surface of the soil, build a small arch shed, play the role of shading and rainproof, wait until 7 days to Qi seedlings, remove the arch shed when growing 2 true leaves, according to the 4 cm plant spacing between the seedlings, pull out the weak seedlings to cultivate strong seedlings, and apply rotting manure to provide nutrition.

4.Field management During the spinach planting period, observe the soil state according to the weather, properly water the soil to keep the soil moist and not waterlogged, and do a good job in the prevention and control of pests and diseases during the growth period, and spray pesticides in advance to avoid serious diseases and cause crop death. Reasonable fertilization in the whole growth cycle of spinach, suitable for topdressing with green water-soluble fertilizer, fertilization needs to use thin fertilizer and frequent application.

Overwintering spinach is generally planted in mid-October and early November, at this time not only grows luxuriantly, but also the best period for spinach vegetative growth.

For the wintering spinach when will be planted with high quality, generally speaking, it is best to plant in mid-October and early November, due to the dry and cold weather in winter, there is frost in the morning and evening, which is conducive to the vegetative growth of spinach, and it is also the growth period of spinach, and the yield will be very large.

If you want to plant better spinach in winter, the first thing is to ensure the quality of seeds, generally choose varieties that are easy to smoke fast, strong wintering, cold tolerance, good quality, and fast growth, and are common in life, mainly spinach, pinehash No. 10, pinehash No. 9.

And if you plant spinach in winter, it is best to apply foot fertilizer in the soil to prepare the land finely, if you sow late, it is best to soak the seeds in cold water for about 12 hours, and then dry the seeds for 3 days.

1. Spring planting

Planting spinach in spring is generally the best when the temperature rises to more than 5 degrees after spring, and it is sown in March in spring, and it is harvested in about April and May.

2. Summer planting

Summer planting is generally in May and July to begin to sow in stages, in mid-June to mid-September harvest, summer high temperature pay attention to cooling and moisturizing, strengthen fertilizer and water management, and irregular soil turning once, generally can choose plowshare pine, Chinese pine No. 1, Guangdong round leaves, etc.

3. Autumn pine

The yield of spinach planted in autumn will also be very large, generally in the autumn of August and September to start sowing, to September and October in batches, and in the autumn planting is best to disinfect the seeds, and then put them in a low temperature refrigerator or cold water for 24 hours of treatment.

Spinach is sown in March in spring, May and July in summer, and August and September in autumn.

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.

Sowing spinach way:

1. Fine-grained land

Plough the land, choose a loose and fertile soil, good drainage section, apply 4000 kg of rotted organic fertilizer per mu, add 40 kg of superphosphate, mix soil and fertilizer, and finely prepare the land to make a field furrow. It is suitable for flat furrows in summer and autumn, and high furrows are suitable for winter and summer, and can be made of meter-wide furrows.

2. Sow seeds and raise seedlings

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.

3. Leave seeds for harvesting

The plant can be harvested when it grows to more than 10 cm, and the spinach used to keep the seeds should be controlled in the water during the budding period, and the male plant can be pulled out after the male plant bears seeds.

The overwintering spinach planting time and method are as follows:

1. Sowing time.

1) Timely sowing is a key factor for the success of overwintering spinach planting, and it can be sown when the average daily temperature drops to 17-19°C according to the climatic conditions of various places.

2) The sowing time is generally from mid-October to early November, and the spinach can be harvested when the plant height reaches more than 10cm.

2. Organize the land.

1) After the harvest of the previous crop, be sure to clean the soil immediately after the crop residues and stones, and then apply sufficient base fertilizer.

2) Generally, 4500 kg of decomposed organic fertilizer and 25-30 kg of superphosphate can be applied per mu, and then ploughed with a plough after fertilization, with a depth of 25cm, and the loose soil is conducive to spinach rooting.

3. Seed selection and sowing.

1) You can choose spinach seeds with strong cold tolerance, full grains, and no diseases and pests, soak them in water for 24 hours, and then place them in an environment of 25 °C to promote germination, which can improve the germination rate.

2) Dig a planting ditch in the field, and then use the method of spreading to sow evenly, and cover the soil and plastic film after sowing, so that the suitable temperature can be maintained.

4. Field management.

1) After wintering spinach planting, when the seedlings grow to 3-4 true leaves, be sure to control the watering, which is conducive to the overwintering of the plants, and generally sprinkle water once a week.

2) In frost and ice and snow weather, we must pay attention to the insulation of plastic arch shed, and you can choose to apply rotted thin manure water on sunny days after spring, which can prevent spinach from sprouting early.
