When are the shallots planted, and when are the shallots planted

1. Planting time.

Generally speaking, it is mainly sown in March and April in spring, and harvested in June and July, and can also be planted in September and October in autumn, and harvested in April and May in the spring of the following year, but it is mainly sown in spring.

2. Planting method.

1. The growth temperature of shallots.

The temperature of shallots should be determined according to their growth habits as much as possible, because shallots prefer cold and cool, so the appropriate temperature is basically about 12 degrees to 22 degrees Celsius, and the temperature should not be too high, because the temperature is too high will lead to the slow growth of shallots, so many farmers say that their shallots do not grow or grow slowly, and a small part of the factors are caused by temperature.

2. Watering skills of shallots.

For the planting of shallots, proper watering can be, the amount of watering should not be too large or the phenomenon of water accumulation, because more water will cause the root of the shallots to rot, so according to the characteristics of the shallots drought tolerance or not waterlogging tolerance, proper watering can be carried out, the soil is dry in the watering on it, it is not recommended that a large number of shallots irrigation operations.

3. Soil selection for shallots.

For the planting of shallots, it is best to choose fertile, loose, drainage, deep soil soil, and for the soil with too much alkalinity, it is necessary to carry out acid and alkali neutralization before planting, because the alkaline soil will affect the growth and development of the green onion, and it is best for the soil pH value to be kept at the to.

4. Fertilization management method of shallots.

The fertilization of shallots should be supplemented with phosphorus fertilizer in time at the seedling stage, and nitrogen and potassium fertilizers should be supplemented in the growth period of shallots, and then appropriate supplementation of micronutrients, basically with nitrogen, phosphorus and potassium fertilizers in different growth periods, and then combined with trace elements for the nutritional needs of shallots, which is more conducive to the growth and yield of shallots.

5. Harvest management.

Shallots are a kind of vegetables that can be harvested like leeks, but the shallots are not perennial, but biennial, even so, every other month, you can also harvest shallots, here we must pay attention to, do not harvest every 10 days because shallots can be cut and harvested, too short time will lead to shallots nutritious roots, it is best to harvest once a month.

Sowing, the growth period of shallots is short, and it is advisable to choose sufficient water and fertilizer conditions for cultivation. Combined with the land tillage and application of sufficient base fertilizer, the application of organic fertilizer, superphosphate, the land raked flat for furrowing, furrow width of meters, row spacing of 20-25 cm, strip sowing 4 rows, shallow soil after sowing suppression watering, and spraying of new high fat film moisture preservation, improve the seedling rate.

Water and fertilizer management, the leaves and leaf sheaths of shallots, watering should be sufficient, after sowing to around 15 cm in plant height, watering sufficient water can make shallots grow rapidly, after entering the middle of growth, the amount of watering should be gradually reduced. Extreme drought or excessive humidity causes thick roots and wilted leaf tips, which affects quality. In fertilization, the main thing should be to promote leaf growth, and fast-acting nitrogen fertilizer should be applied.

And spraying vegetable stems can make vegetable seedlings grow luxuriantly, with thick stems, thick leaves, high yield and high quality. Long shelf life. After the seedlings begin to grow vigorously, generally every 20 days or so, apply 1 fast-acting nitrogen fertilizer, with the application of an appropriate amount of phosphorus and potassium fertilizer, and each application of ammonium sulfate + plant electronic fertilizer.

For the green onions sown in autumn and overwintering, the fertilizer and water should be properly controlled before the green onion seedlings are wintered, so as to prevent the seedlings from being too large before winter and a large number of early sprouts occur in spring. After the green onion seedlings return to green, they should be watered back to green water in time, apply green fertilizer, apply urea, promote early growth of seedlings, and apply ammonium sulfate every 20 days in the future, fully watered, strengthen vegetative growth, and improve yield.

It's now, when it's time for planting.

The time when shallots are grown is all year round. Planting method: variety selection, planting, land preparation and fertilization, picking.

Chives can be planted in all seasons, the suitable growth temperature is between 18 degrees Celsius and 23 degrees Celsius, and the chives are not drought tolerant, and the light intensity requirements are medium. Spring stubble: transplanted in January, harvested from March to mid to late April, summer stubble:

It is transplanted from late April to early June and harvested from May to the end of July. Autumn stubble: transplanting from August to late September, and marketing from mid to late September.

Winter stubble: transplanted from October to November, harvested from January to February.

Cultivation Method:

1. Variety selection

The main varieties are four seasons rice onion, Sichuan small onion, Lu onion No. 1, Chongzhou horn onion, etc., generally choose white or purple flowers, spicy and fragrant varieties.

2. Colonization

Before planting, the seedlings should be screened to remove diseased, disabled and weak plants. After screening, cut off the apex of fibrous roots, leaving 2 3 cm to promote the development of new roots. Transplant according to the row spacing of 20 cm and the plant spacing of 10 cm, and plant 4-6 plants per hole.

Spring onions, autumn onions can be appropriately sparsely planted, planting should be shallow, about 3 cm - 5 cm, after planting timely watering water.

3. Soil preparation and fertilization

Choose flat, loose, fertile, well-drained and watered fields for transplanting fields, and it is best to rotate with soybeans, corn and other vegetables, not with onions and garlic. 2000 kg of high-quality organic fertilizer and 50-70 kg of ternary compound fertilizer are sprinkled per mu, and the land is finely prepared, and the high furrow is made of rice width, and the ground temperature can be increased by covering the plastic film in winter, so that one more stubble can be harvested.

4. Picking

Harvesting chives should be carried out in the early morning or evening on a sunny day, the knife edge of the green onion is 2 3 cm from the surface and the knife edge is neat and consistent, after each harvest, the ground is raked again with a rake, and the wound of the green onion is healed after 3 days, and the new leaves are about to be watered. Do not harvest during the summer solstice to prevent the seedlings from dying.

1. Shallots are planted in spring and autumn.

2. Green onions prefer a warm and cool climate. It is best grown in an environment of 15 to 25 degrees. In northern China, it is usually planted in spring and autumn.

Spring usually falls around the Qingming Festival. Autumn is the most suitable time to plant shallots. Green onions can tolerate severe colds and winters.

3. The temperature of green onions should be determined according to their growth habits as much as possible. Because shallots prefer cold and cool, the right temperature is basically 12 to 22 degrees. It should not be too high, as too high a temperature will cause the shallots to grow slowly.

As a result, many farmers and friends say that their green onions don't grow or grow very slowly, and a small part of the factor is caused by temperature.

Shallot sowing and planting is generally selected in February to March every year, in the Yangtze River basin is generally sown in March to April, harvested in June to July, can also be sown in September to October, and can be harvested in April to May of the second year.

The temperature of shallots should be determined according to their growth habits as much as possible, because shallots prefer cold and cool, so the appropriate temperature is basically about 12 degrees to 22 degrees Celsius, and the temperature should not be too high, because the temperature is too high will lead to the slow growth of shallots, so many farmers say that their shallots do not grow or grow slowly, and a small part of the factors are caused by temperature.

For the planting of shallots, proper watering can be, the amount of watering should not be too large or the phenomenon of water accumulation, because more water will cause the root of the shallots to rot, so according to the characteristics of the shallots drought tolerance or not waterlogging tolerance, proper watering can be carried out, the soil is dry in the watering on it, it is not recommended that a large number of shallots irrigation operations.

Shallot breeding environment:

1. Light: The right amount of light conditions can meet the growth, the light can not be too strong, and it is easy to make the plant old if it is exposed to strong light for a long time.

2. Moisture: When the onion grows to more than ten centimeters, it is necessary to water it in time, and only when the watering condition is met can the rapid growth of the onion be promoted.

3. Fertilization: Fertilization can be carried out about once every 10 days to meet the supply of nutrients.

Shallots in the Yangtze River basin are generally sown in March and April and harvested in June and July; It can also be sown in 9 October and harvested in 4 May of the following year. During this period, the young seedlings that have not grown up are mainly eaten in the market. It is advisable to choose flat terrain, good drainage, fertile soil for planting, regardless of sandy soil, clay loam soil, the soil pH requirements are not strict, slightly acidic to slightly alkaline.

However, it is not suitable for many years of continuous cropping, and it is not suitable for stubble with other onions and garlic vegetables. After selecting the plot, it is immediately ploughed, and generally 2500 3500 kg of rotting manure or manure are applied per mu, plus 30 35 kg of phosphorus and potassium fertilizer, or 40 kg of compound fertilizer. After the application of the rake to make furrows, the width of the furrow is about 2 meters, the width of the furrow is 40 cm, the depth is 15 25 cm, so that the "three furrows" matching, can be irrigated and drained.

1. Chives like cool climate, cold tolerance and heat resistance are strong, germination temperature is 13-20 degrees Celsius, stem and leaf growth suitable temperature 18-23 degrees Celsius, root growth suitable ground temperature 14-18 degrees Celsius, slow growth rate above 28 degrees Celsius. Due to the shallow distribution of the root system, the water requirement is less than that of green onions, but it is not drought tolerant, and the suitable soil moisture is 70%-80%, and the suitable air humidity is 60%-70%. Medium intensity is required for light conditions, and the tissue is easy to age, the fiber increases, and the quality deteriorates under strong light conditions.

2. Planting in spring and autumn; The protected area can be planted all year round except in summer; Yanqing, Huairou, Miyun and other northern mountainous areas can be covered with shade nets in summer. Generally, it is harvested 60-80 days after sowing, and can be harvested successively 30 days after transplanting.

3. Whether sowing seedlings or transplanting, the land should be carefully prepared and sufficient base fertilizer should be applied. Apply rotted, finely minced organic fertilizer or puffed rotted chicken manure.

4. 40-50 days after sowing can be transplanted, every 8-10 plants a hole, row spacing 12-20 cm, hole spacing 8-10 cm, shallow not deep, 4-6 cm is appropriate, timely pouring slippery rent messy planting water. It can also be harvested without transplanting after sowing.

5. Before and after the emergence of seedlings and transplanting the soil can not be dry, it is advisable to water frequently, control the watering of seedlings at 1-3 leaf stage and transplanting seedlings, cultivate loose soil 1-2 times, type Zen to promote root growth, and generally water once in 7-10 days. If the basal fertilizer is applied less, or the harvest period is too long, top dressing should be 1-2 times, apply rotted puffed chicken manure, and the roots should be cultivated 1-2 times in the later stage. In summer, the temperature is high and the light is strong, so it is necessary to build scaffolding to cover the shade net.
