Onion planting method and time, onion planting method and time

2. Soil: When planting green onions, it is necessary to provide them with deep and fertile soil that is convenient for drainage and irrigation.

3. Watering: After the green onion emerges, it should be watered according to the wall condition of the soil to avoid rotten roots.

The planting time of shallots is usually in autumn, and it can be planted in autumn and winter in southern China, and soft, nutritious and well-drained and permeable soil can be used for planting; Give it some scattered light every day, and it will grow well; It is relatively cold-tolerant, and the temperature at the germination stage is controlled at 13 -20 at the best time, and the temperature above 28 degrees Celsius will reduce its growth rate; Because the root system is relatively sparse, the water requirement is not very sufficient.

Have you learned the time and method of planting shallots.

Chives are generally best planted in spring, it can germinate normally at 13 20, the growth temperature of the plant is 10 25, if it is higher than 28 degrees, the growth of chives will be very slow, and the planting method of chives in spring is also the simplest, and the yield will be very large. Planting chives can also be planted in autumn, generally in September and October, due to the large temperature difference in the autumn climate, the roots of the chives can fully absorb the nutrients, and the chives in autumn are also the most nutritious, and the taste will be very good.

Planting method: seed selection and germination.

If you plant chives, you generally choose clean and full seeds to survive the highest, and then put them on the cultivation surface, cover the surface with a thin layer of soil, water thoroughly, and germinate after about 2 weeks in a dark greenhouse.

Soil preparation management. Chives prefer loose and fertile well-drained soil, generally with rotten leaf soil, pond mud, river sand, and manure according to 2:2:1:

The ratio of 2 is mixed and prepared, and then a small amount of water is poured to keep the soil moist and the soil is optimal, and then a small amount of decomposed organic fertilizer can be applied as a substrate.

Planting management. Sprinkle the germinated seedlings into the soil separately, and leave one end of the bud end downward, keep the spacing at about 10cm, and then cover the surface with 1 2cm of thin soil, and then pour in the appropriate amount of water is the best.

Fertilizer and water management. After planting, it is best to ensure that it can not be exposed to strong light for a long time, and it can be properly shaded, and the soil should be loosened from time to time, watered every 1 3 days, and add Bika water-soluble fertilizer every 15 days or so.

Prevention of pests and diseases. Chives are common in the growth stage of downy mildew, soft rot and so on.

1.Choose good breeds. Before planting, be sure to choose the varieties planted according to the climate of the region, you can first do relevant research on the basic situation of local green onion planting, and then choose some high-quality and high-yield, and have a good market for planting.

2.Fertilization of the land. Green onions are not very demanding when planting, they only need to be in sufficient light and close to a water source suitable for watering.

When planting, choose plots with rich organic matter in the soil, turn at least 30 cm deep when acquiring land, and clean up the weeds and pest residues contained in the soil, and finally choose the right fertilizer for fertilization. 3.Scientific planting.

There are three main ways of green onion planting, which are planting propagation, branch propagation and bulb propagation. The most suitable time for planting is around May to June every year, when planting should be strictly in accordance with the interval of 30 cm per row of ditch for strip sowing or strip planting, the interval of each plant is about 5-8cm. It must be noted that the ground must be watered thoroughly before the end, so as to improve the survival rate of green onions.

Avoid heavy stubble, heavy stubble to reduce yield, continuous cropping for three years to reduce the yield seriously, almost out of production. Green onions require neutral* soil, and the allowable pH range for cultivation is.

2. Sowing: Zhangqiu green onion seedlings are divided into autumn seedlings and spring seedlings, mainly in autumn, and autumn sowing is the best time to take a week around October 5 (follow up immediately after sowing winter wheat). Spring sowing after the Spring Festival thaw, the earlier the better, in order to prevent low temperature and drying, it can be covered with plastic film.

Miao wo finishing, according to 80 cm after the whole wow, spread, 1-2 cm can, mu fertilizer (compound fertilizer or diammonium 30 kg). Mix about 10 times per mu and sow by hand. Watering after sowing, 2-3 days after the light cocoon wow surface to loosen * moisture protection, 10 days to do about the seedlings that come out, without any management.

3. Seedling management: pre-winter management, after the seedlings emerge, watering in case of drought, and watering frozen water before freezing to ensure safe wintering. Spring management, the seedlings are too dense, and the transplanting solves the uneven seedlings, that is, the dense seedlings are thinned, and the small ones are left large.

After the Qingming Festival, water two to three times in case of drought, and each top dressing shall not be less than 30 catties of three-element compound fertilizer per mu. In early June, the water was stopped to control the seedlings and prepare for transplanting.

Have you learned the time and method of planting shallots.

Seedling: Choose plots with good drainage and fertile soil for seedlings, do a good job of soil plowing before planting, and apply enough fertilizer to ensure that the seedbed soil is loose and has good drainage. After the emergence of green onions, do a good job of water and fertilizer management at the seedling stage to keep the soil moist.

Fertilization: Use about 5 kg of urea per mu for top dressing, and start transplanting and planting work in late October when the green onions grow. Do a good job of soil plowing and fertilization before transplanting, control the depth of tillage at about 25 cm, use 3000 to 4000 kg of well-rotted organic fertilizer per mu according to soil fertility, and use about 15 kg of compound fertilizer.

Field management: first of all, the management problem after transplanting, pay attention to check whether there is a lack of seedlings and dead seedlings in the field after transplanting, timely replenish the seedlings, reduce weeds in the field, and then water and fertilizer management problems, watering according to the soil and seedling stage, and stop watering about 20 days before the harvest of green onions. In the growth stage of green onions, a total of 4 to 5 times of fertilization, according to the growth of green onions, fertilization should be carried out, and finally attention should be paid to the control of green onion diseases and pests.

Have you learned the time and method of planting shallots.

The seeds are planted in spring and autumn, with spring in February or March, harvested in June, and autumn in September or October. Cultivation soil, the cultivation environment of green onion should choose a high terrain, deep soil layer, convenient drainage and irrigation, and fertile soil.

To carry out sowing, sow the seeds on moist soil, cover with a thin soil of about 1 cm, and gently press the soil. Maintenance management, onion growth needs a certain amount of light, when the onion grows tall, we must ensure that the water is sufficient, timely watering and irrigation, but also pay attention to fertilization, to ensure good nutrients.

Farming techniques

Pruning: After a period of cultivation, the leaf tips of green onion leaves will turn yellow, so small scissors should be used to prune them off to avoid all the leaf tips turning yellow. When it grows up and is ready to eat, cut off the top and eat, leaving about three centimeters of green onion white at the bottom, and you can continue to grow.

Propagation: Propagation with sowing is sufficient, first turning the soil and then spreading the seeds evenly on the soil. Sprinkle another centimeter or so of soil on it, and then cover it with mulch film to keep it warm, and you will see small buds grow out in about 30 days.

Growing conditions

1.Soil. The pH value of the soil for green onion planting is suitable, and about 10 to 15 days before planting, the moisture in the soil can be controlled to prevent lodging.

2.Manure. The fertilization of green onions requires the balanced application of phosphorus, potassium and nitrogen fertilizers, and the demand for nitrogen fertilizer is high in the early stage of growth, and the demand for phosphorus and potassium fertilizer is more in the later stage.

3.Temperature. Green onions are good resistance to stress, and they are both cold and heat tolerant.

4.Moisture content. The root system of green onions is more afraid of waterlogging, and high temperature and humidity will easily cause death.

5.Illumination. The intensity of green onions to sunlight is only moderate, and strong light will cause a decrease in quality.

The planting time can be sown in spring and autumn every year, and it can be carried out around the autumn equinox in autumn; To select seeds for germination, it is necessary to select seeds with full particles, and after germination, the seeds are evenly sown into the soil and covered with a thin layer of soil; Transplanting and planting, when the seedlings grow to 40 to 50 cm, they can be transplanted and planted in early June; For field management, it is necessary to build a layer of shade net above to weaken the strength, and water it every 2 to 3 days.

Onions can be sown in spring and autumn every year, during which the ambient temperature is stable between 15 and 20, the climate is cool and humid, and the onion seeds can germinate and resume growth as soon as possible after sowing. Spring can be carried out around the Qingming Festival every year, and autumn can be carried out around the autumn equinox, and the specific sowing time needs to be appropriately adjusted according to the local climatic conditions.

In order for the onion seeds to germinate as soon as possible after sowing, it is necessary to select clean and full-grained seeds for germination. Before sowing, the plot needs to be leveled, watered with water once, and then evenly sown the green onion seeds into the soil, covered with a layer of centimeter-thick thin soil, and watered with water once so that the seeds can germinate better.

When the shallot seedlings grow to 40 50 cm, the thickness is 1 cm, you can transplant and colonize in early June to early July every year, the row spacing is controlled at 70 80 cm during the planting period, and the plant spacing is 5 6 cm.

Onion seedlings grow relatively thin during the seedling period, not resistant to strong direct light, can build a layer of shade net above to weaken the intensity of light, in addition, it is also necessary to regularly loosen the soil around the plot, water every 2 3 days, and apply a thin and well-rotted organic fertilizer solution every 15 days, so as to improve the overall yield and quality of the plant.

<> put the clean and plump seeds into the cultivation soil surface, cover with a thin layer of soil and water thoroughly, and place them in a dark greenhouse for germination, and they can germinate after about 2 weeks; Use rotten leaf soil, pond mud, river sand, and dung according to 2:2:1:

The ratio of 2 is mixed to prepare planting soil, the germinated seeds are sprinkled into the soil, the spacing is 10 cm, the thin soil is covered and properly watered, and transplanting can be carried out in 40-50 days. In the later stage, strengthen the management of fertilizer, water, temperature, etc., and harvest in a timely manner.

1. The planting time of green onions

Spring planting onion is more suitable, green onion can germinate normally at 13 -20 temperature, the growth temperature of the plant is 10 -25, and the growth rate of green onion slows down when the temperature is higher than 28. You can also choose to plant green onions in autumn, the planting time is generally from September to October, and the temperature difference in autumn is large, which can allow the roots of chives to fully absorb nutrients.

Second, the planting method of green onions

1. Planting green onions generally selects clean and full seeds, the survival rate is high, and the seeds are put into the cultivation soil surface after selection, and then covered with a thin layer of soil, watered thoroughly, and placed in a dark greenhouse for about 2 weeks before germination. Onions like loose and fertile, well-drained soil, can be used rotten leaf soil, pond mud, river sand, dung soil according to 2:2:

The ratio of 1:2 is mixed and prepared, and then a small amount of water is poured to keep the soil in a moist state, and finally a small amount of decomposed organic fertilizer can be applied.

2. Sprinkle the germinated seeds into the soil, leave one end of the bud end downward, control the spacing at about 10 cm, cover the surface with 2 cm of thin soil, and water properly to keep the soil moist. 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 should not be deep, 4-6 cm is appropriate, timely watering planting water. It can also be harvested without transplanting after sowing.

3. Green onions like a cooler climate, strong cold tolerance, 13 -20 is the most suitable during the germination period; The best growth period of stems and leaves is 10 -23, and the growth rate will have a significantly higher decline when the temperature exceeds 28.

4. Before and after the emergence of seedlings and after transplanting, the soil can not be dry, it is advisable to water frequently, control watering after seedling 1-3 leaf stage and transplanting seedlings, cultivate loose soil 1-2 times to promote root growth, and generally water once in 7-10 days. If the basal fertilizer is applied too little, or the harvest period is too long, top dressing should be 1-2 times, and the rotting puffed chicken manure should be applied.

5. Generally 60-80 days after sowing or 30 days after transplanting can be harvested, harvesting onions should be carried out in the early morning or evening on a sunny day, and the root of the chives should be grasped by hand during harvesting, and then pulled out by rooting, and the harvested onions should remove the wilted and yellowing leaves.

Onion planting methods: planting time, cultivation soil, water irrigation, top dressing, planting management.

1. Planting time

The time for planting onions is generally between early June and early July every year, in fact, the selection of green onions for the planting period is not so strict, but in order to ensure their viability and growth, it is best to follow the standard process. Sowing seeds in spring and sowing green onions is chosen in spring and autumn.

2. Cultivation soil

The cultivation environment of green onion should choose a high terrain, deep soil layer, convenient drainage and irrigation, and fertile soil. Sufficient compound fertilizer, superphosphate, urea and other fertilizers can be added to the soil as base fertilizer to improve soil fertility. Ground planting onions must be deep to the soil, rake flat, ditch and make ridges.

, water irrigation

During the growth of green onions, watering is divided into four stages. The first stage is in the slow seedling oversummer stage, the second stage is in the middle and early August leaf peak period, the third stage is its peak growth period, irrigated by the principle of frequent watering and heavy watering, and the fourth stage is after late October, slowly reducing the water irrigation.

4. Top dressing fertilizer

The frequency of topdressing of fertilizer was three times, the first time was to apply urea fertilizer after the seedlings were slowed down in early August and before the peak leaf stage. The second time is in late August, in addition to urea, potassium sulfate can also be used for topdressing. The third time is topdressing in early September, also irrigated with urea.

5. Colonization management

Before planting, the size of the seedlings is separated, and the diseased seedlings, weak seedlings, small seedlings and obviously bent seedlings are removed, the plant spacing is 35-40 plants per meter, the row spacing is 1 meter, and about 10,000 plants are planted per mu. When planting, avoid breaking the green onion seedlings, the planting depth should not bury the green onion heart, too deep should not sprout, too shallow to affect the length of the green onion. When planting, the leaf surface and the planting furrow should be arranged in a vertical direction, which is conducive to dense planting and management.
