The planting method and time of shallots, and the planting method and time of shallots

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. 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.

Onion planting time.

Spring shallots are planted in January, and harvesting usually begins around mid-April. It is often cultivated with mulching. Shallots prefer moist conditions, but are afraid of too much water.

Therefore, the management of the water cavity is strict. It is required to be kept moist and not have too much water. Therefore, it is advisable to avoid cohesive soils and low-lying plots as much as possible.

The summer planting time is from May to July, and it is generally cultivated with shade nets. The climate during this period is more suitable for the growth of shallots. It is recommended to decide according to the local climatic conditions, and the temperature can be pushed back if the temperature is a little higher.

Autumn planting time is generally in the month of January, because the temperature of onions is higher during this season. You can spread some straw between the rows to cool down and moisturize, so that the onion grows better. The planting time is usually in October, January, November, or February.

Onions have high requirements for temperature and humidity, and it is necessary to pay attention to the soil moisture content between 40%-60% and the temperature between 15-25.

Onion planting method.

1.Choose green onion seedlings: Green onion seedlings are generally purchased in the market.

When choosing, try to return to the full cherry blossoms and choose fresh ones, and don't buy wilted ones. And the green onion root should be intact and with a little soil on top, which is the best choice. 2.

Prepare containers: Onions can be grown in any container. Flower pots or other containers for growing vegetables are possible.

It is also possible to put onions and flowers together in a drain, which is a great way to save space. 3.Simple handling:

Before planting green onions, handle them first. The leaves of green onions can be cut off and eaten. When cutting, try to leave as many green onions as possible, which is convenient for planting and easier to survive.

4.Grow onions: Put nutrient soil in pots, dig a pit, put onions in them, then bury the soil and flatten it.

Onions have strong vitality and can be planted well. 5.Watering and fertilizing:

After planting the onions, water them and maintain them in a sunny area. As long as the temperature is above 0 degrees, they will generally survive. After about 7 days, the sprouts will grow.

At this time, it is necessary to apply some organic fertilizer in time, which is more conducive to the growth of onions.

1. Planting time.

The onion itself is hardy, generally sown in March and April, harvested in June and July, and can also be sown in September and October, and harvested in April and May of the following year. In the southern region, jujube liquid can be planted in autumn and winter.

Second, the planting method is buried.

1.Soil: Prefer soft, nutritious, well-drained, and well-permeable soil, not suitable for planting in sandy soil.

2.Light: It prefers mild scattered light.

If the light is too strong, you need to shade it, otherwise the leaves will turn yellow, the fiber will increase, and the taste will be poor. 3.Temperature:

Prefers cooler climates and is hardy to cold. The germination period is 13-20 is the most suitable; 10-23 is the best time for stem and leaf growth. When the temperature exceeds 28, the growth rate decreases significantly.

4.Watering: The root system is sparse, requiring less water than green onions, but it is not drought resistant, and the soil should be kept warm and moist.

5.Fertilization: Spring and summer are its growth period, and fertilization can be applied 1-2 times as appropriate.

The first topdressing takes 20-25 days and the second takes 12-15 days.

The shallots themselves are relatively hardy, and are generally sown in March-April and harvested in June-July, but can also be sown in September-October, and harvested in April-May of the following year, and can be planted in both autumn and winter in the southern region. <>

1. Soil: It likes soft, nutritious, drainage, and air permeability soil, and is not suitable for planting in sandy soil.

2. Light: It prefers gentle scattered light, if the light is too strong, it needs to be shaded, otherwise there may be yellowing of leaves, increased fiber, poor taste, etc. <>

3. Temperature: It likes a cooler climate, strong cold resistance, and 13 -20 is the most suitable during germination; 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. Watering: The root system is relatively sparse, so it needs less water than green onions, but it is not drought tolerant, and the soil should be kept warm and moist.

5. Fertilization: Spring and summer are its growth period, you can chase 1-2 times of fertilizer as appropriate, the first top dressing can be in 20-25 days, and the second top dressing can be in 12-15 days. <>
