Summer spinach planting techniques? What techniques are there for spinach cultivation in the summer

Spinach can be grown all year round, what attention do we need to pay attention to when growing spinach in summer? What is the method of growing spinach in summer? Let's sort out the information and learn what the summer spinach planting technique is! The article is for your reference!

1.Origin environment.

Choose a plot with fresh air, pure water, unpolluted soil, deep, loose and fertile soil.

2.Variety selection.

Summer spinach, also known as "spinach", is a spinach that is marketed from July to August. The seedling growth period is in the high temperature and long sunshine season, although the leaf primordium differentiates quickly, but the flower bud differentiation and sprouting are also fast. Moreover, the temperature is high, the evaporation is large, the respiration is vigorous, the plant nutrient accumulation is small, the growth of leaf area is limited, the quality is poor, and the yield is low.

Therefore, summer spinach should choose some varieties that are more resistant to heat, waterlogging and lodging, such as Green Vulcan, Goldman Sachs, Fonda and Porfit. Summer spinach cultivation should focus on solving the problems of seedling emergence, seedling preservation and robust growth.

3.Sow. Determine the appropriate sowing date:

Sowing from early to mid-June to July, harvesting about 50 days after sowing, and the sowing period can be arranged more than 50 days before the planned market. At the same time, it is necessary to arrange sowing before the arrival of summer temperature as much as possible, so that the seedlings can grow for a period of time and then enter the high temperature period, which is conducive to obtaining higher yields. Therefore, the suitable sowing date for summer spinach is early to mid-June.

Soaking and germination: Summer spinach must be soaked at low temperature before sowing. The method of this is:

Soak in well water for 24 to 30 hours, wrap it in gauze, hang it in the well about 20 cm above the water surface, sink the gauze bag into the water every day and wash the seeds once, and then sow the seeds after 2 to 3 days until the seed radicle is exposed. The soaked seeds can also be spread in a cool place indoors to germinate, pay attention to turning and maintain a certain amount of moisture, and they can also germinate after 5 to 6 days. Or the soaked seeds can be placed at 15 to 20 times to germinate, and germination will occur in 3 to 4 days.

Fertilization and sowing: Before cultivating land, 2000 to 3000 kg of rotted farmhouse fertilizer, 20 kg of Trim granule compound fertilizer and 10 kg of urea are applied per mu. It is also necessary to apply kilograms of zinc fertilizer and kilograms of boron fertilizer as base fertilizer.

Shallow tillage rake, made into a meter-wide flat furrow (including ridge), the furrow surface must be flat, the furrow should not be too long, about 15 meters is appropriate. Before 10 a.m. and after 4 p.m., seeds are sown using the wet sowing method. That is, water first, and after the water seeps down, sow the seeds and cover them with 2 cm of fine soil.

In order to ensure a sufficient number of seedlings, the sowing rate can be increased to 8 to 10 kg per mu.

After sowing, cover the furrow surface with crop straw to cool down and moisturize, prevent heavy rain from washing, and ensure that the seedlings are evenly matched. Try not to water before the emergence of seedlings, so as not to wash off the cover soil when the soil is compacted or watered, so that the seeds are exposed and affect the emergence of seedlings. After emergence, remove the mulch in the evening or morning.

1.Spinach has a thicker root system and easily absorbs water. It has high requirements for soil, and usually uses high-quality soil with good drainage capacity.

2.Spinach is usually sown and the seeds should be soaked in water for 12 hours one week before planting.

3.Remember to sprinkle a layer of plant ash after sowing. Spinach grows relatively fast and usually germinates in about seven days after the seeds.

Spinach (spinaciaoleraceal.)Also known as Persian vegetables, red root vegetables, parrot vegetables, etc., it belongs to the genus Spinach in the Chenopinoa family, an annual herbaceous plant. The plant can be up to 1 m tall, with conical, reddish-tingting, less white, leaves 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.

Spinach is a plant of the Chenopodaceae family, which is cold tolerant and adaptable, and is widely cultivated throughout China. Spinach is rich in nutrients and has a short growth period, making it one of the important green leafy vegetables.

The straight roots of spinach are well developed, and the main root groups are distributed in the cultivated layer of 25 30 cm, which is not too strict on the soil, has weak acid resistance, and is suitable for pH, which can be adjusted by silver ions in dry farming.

Spinach needs nitrogen, phosphorus and potassium complete fertilizer, and the absorption ratio of nitrogen, phosphorus and potassium is 1::, and special attention should be paid to nitrogen fertilizer on the basis of the three elements. Sufficient nitrogen fertilizer can make the leaves grow vigorously, not only improve the yield and improve the quality, but also prolong the first periodWhen nitrogen is deficient, the plant is short, the leaves are yellow, and it is easy to sprout unripely.

Among nitrogen, spinach prefers nitrate nitrogen than other vegetables. Each 1000 kg of production absorbs kilograms of nitrogen, phosphorus, and potassium.

There are many cultivation methods of spinach, which can be overwintering root stubble and buried spinach in the north, and can also be cultivated in the open field in spring, summer and autumn, and in recent years, the cultivation of protected land has formed a certain scale. In terms of production, overwintering spinach has a large area and is one of the main vegetables in early spring.

The amount of fertilizer applied varies from region to region and from cultivation period to cultivation, but the basic principle is the same. The fertilization technology of spinach is introduced by taking overwintering spinach as an example.

Spinach can be planted all year round, the best planting time is in May to July in summer, but spinach seeds can not germinate in a high temperature environment, so it is necessary to keep the ambient temperature below 25 or less than the ring ridge, and the most suitable growth temperature is 15-20.

Spinach can be grown all year round, and the best time to plant it is from May to July in summer, but the seeds of spinach cannot germinate in a high temperature environment, so keep the ambient temperature below 25.

The most suitable growing temperature for spinach is 15-20, which is a long-day crop with strong adaptability to the soil, but the fertile and loose soil is the best, and sufficient water is required during the growing period.

How to grow spinach in summer.

1. Soil selection: It is best to choose fertile and well-drained soil for spinach planting, and some coarse sand and coal ash can also be added to the soil to improve the air permeability of the soil.

2. Seed selection: When planting spinach, it is best to choose seeds of cold-tolerant varieties, and the seeds should be within the shelf life, so as to ensure the germination rate of seeds.

3. Sowing: Spinach can be planted by sowing, the seeds should be soaked for more than 12 hours before planting, and the temperature should be kept between 20-25 after sowing.

Spinach summer maintenance management.

1. Shading and rainproof: spinach is a crop that is not tolerant to strong light and high temperatures, so it is necessary to do a good job of shading in summer, and the effect will be better if you build a rain and sunshade net.

2. Prevention and control of pests and diseases: spinach is easy to suffer from cataplexy and frost finger tung mildew in summer, so it is necessary to spray pesticides in time for prevention and control, and compound prevention and control should be carried out according to the characteristics of different agents.

Different varieties of spinach are grown at different times.

Spinach is grown from August to September in the fall. Overwintering spinach is sown from mid-October to early November, while spring spinach can be planted in March in the spring, and summer spinach is usually sown in phases from May to July in the summer.

For autumn sowing, soak the seeds in water for more than 12 hours one week before planting. After soaking, the seeds should be stored at an ambient temperature of only 4 for 24 hours (if the temperature is not enough, they can be placed in the refrigerator) and then germinated at 20 25 °C. Once the seeds have germinated, they are ready to be planted.

Autumn spinach planting time. Autumn spinach is generally sown in August-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.

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

Different kinds of spinach planting time is not the same, autumn spinach planting time in August and September, overwintering spinach in mid-October to early November to start sowing, and spring spinach can be planted in spring in March, summer spinach is generally in the summer of May and July in phases sowing is the best.

1. The planting time of autumn spinach.

Spinach is now a vegetable that appears more on the table, for when to plant spinach is the best, in fact, it is sown by type, among which autumn spinach is generally sown in August and September every year, at this time it is also the time when spinach grows rapidly, and it can be harvested about a month after sowing.

2. The planting time of overwintering spinach.

Overwintering spinach is generally sown from mid-October to early November every year, because spinach is a cold-tolerant vegetable, its seeds can continue to grow and germinate in an environment of about 4 degrees, in order to make it grow quickly, it is best to warm it or put it in a greenhouse, and it can be harvested during the Spring Festival.

3. The planting time of spring spinach.

Spring spinach is usually sown at a temperature of 5 °C after the beginning of spring, and it is best planted in March in spring, and the yield of spinach planted in spring is higher than that of other seasons, and it is also the best period for varieties, and it can be harvested after 30 to 50 days after sowing, and it is also the best time to eat and taste.

4. The planting time of summer spinach.

Spinach can also be planted in the summer, preferably in phases between May and July, and with heat-tolerant, fast-growing varieties that can be harvested in large quantities from late June to mid-September, to supplement the low yields of other seasons.

2. Precautions for planting spinach.

Generally, after spinach planting, it is best to apply manure and water solution every two weeks after the real leaves, and weeding treatment should be carried out in time. During the seedling period, the organic fertilizer solution is mainly decomposed, and the urea solution should be applied in the growing season, and the appropriate amount of water can be poured when applying.

Growing spinach in the summer requires proper shade, shade and sun protection when the sun is strong, and open air when it is rainy. In the seedling stage of spinach, it is necessary to water more, generally in the morning or evening, frost weather and ice and snow weather can be covered with a layer of protective film to keep warm so that it can grow normally.

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 gathered in about a week.

2. Field management

Spinach has strong growth, 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 headaches, dizziness, redness, night blindness, thirst, constipation, and hemorrhoids.

Planting time, it is best to plant spinach in spring, the temperature is higher than 5 before sowing, summer needs to be in May July, autumn needs to be in August and September; For sowing seeds, it should be planted in loose and fertile soil with good drainage performance, and an appropriate amount of fertilizer should be applied before planting; Proper watering, sufficient watering before planting, and covering with plant ash after planting; Temperature and light, the temperature should be kept at about 20, and sufficient light should be provided.

Spinach is suitable for planting in the spring, when the temperature gradually rises above 5. If planting is carried out in the summer, it is best to sow in May and July, but it can also be planted in autumn in August and September. If overwintering spinach is planted in winter, it should be in 10-11 months.

It is best to plant spinach in loose and fertile soil with good drainage, before planting, you need to apply an appropriate amount of organic fertilizer in the soil, you can also apply superphosphate as a base fertilizer, level the soil and then soak the seeds in water for germination treatment, and then use the spreading method for sowing.

The soil needs to be watered with enough water before planting, and after planting, it needs to be covered with a layer of plant ash to ensure that the soil remains moist. Spinach needs a lot of water during its growth, it has a large leaf area and should be watered in a timely manner, preferably twice a week.

Spinach is more cold-tolerant, and the seeds will germinate in an environment of 15 to 20, which is suitable for growing in an environment with a temperature of about 20. Ground planting also needs to keep the temperature above -6, it is a long-day plant, it needs a lot of light during the growth period, good light will make the plant grow better.
