How to plant green onions, how to plant green onions

Four seasons of green onions can be harvested for 2 to 3 years at a time, generally sown in months or months. The original chive planting habits in the rural areas of our city, vegetable farmers are sporadically planted, but do not pay attention to yield and efficiency. In recent years, the planting area of green onions has gradually increased, and some professional households have emerged in large-scale planting.

Through continuous summary and improvement of cultivation technology, the yield has increased year by year, reaching an annual yield of 7,000-8,000 kg of chives per mu, and a net income of more than 6,000 yuan per mu, which has produced high economic benefits.

1 Breed characteristics.

Four seasons green onion is drought-resistant, cold-tolerant and heat-resistant, and the requirements for soil, temperature, fertilizer, seedling age are not strict, and the disease resistance is strong, and it is suitable for sandy loam and loam planting.

2 Cultivation methods.

Using a sowing and multiple harvesting, it can be harvested for 2-3 years after a sowing, and 7-8 stubbles can be harvested in a year. After planting for 2 to 3 years, the plant becomes thinner and grows poorly, so it should be replanted in a selected place, and it is not suitable for continuous cropping.

3 Cultivation techniques.

1) Fine land preparation, apply sufficient base fertilizer, and green onions should be grown in loose and fertile soil in all seasons, before planting. The land should be fully turned over and the number of pests and diseases should be reduced as much as possible. Use decomposed organic fertilizer as base fertilizer, generally apply 2500 kg per mu, and apply 40kg of ternary compound fertilizer.

2) Timely sowing, the temperature of the growth of green onions in all seasons is 10-25, and it can be planted all year round, with good quality and strong adaptability. In the summer high temperature season, it can be covered with a sunshade net to cool down, and in winter, it can be covered with a small arch to keep warm. Local perennial planting should be sown in the month, but it can also be sown in the month.

3) Cultivating strong seedlings, dense planting and shallow planting, whether live broadcast or transplanting, must cultivate strong seedlings, generally about the amount of sowing per mu, to achieve uniform precision sowing. The furrow is wide, and too wide is not conducive to management. The transplanting depth should be shallow but not deep, 6-7cm, the density should be dense and not thin, the row spacing should be 15-10cm, and each hole is 3-5 plants.

After planting, water enough to facilitate survival. After planting, shallow hoeing loosens the soil and weeds.

4) Thin fertilizer and light application, moist soil, shallow distribution of onion roots in all seasons, weak absorption, so it is not tolerant to thick fertilizer, drought and flood, and poor competitiveness with weeds. The growth period of the four seasons onion is short, the number of stubble, the direct seedling seedlings 60-80d market, the transplanted seedlings 30-40d on the market, the soil should be kept moist after planting, generally about 7 days to water once, combined with top dressing, with urea top dressing. In summer and autumn, when it is dry, it can also often keep semi-ditch water, so that the furrow soil is always moisturized.

Especially in summer, water exchange through furrow irrigation and drainage can reduce soil temperature and prevent high temperature delay and injury to seedlings. In the rainy season, it is necessary to do a good job of ditch cleaning and drainage.

5) Disease prevention and insect control, reduce pollution, the main diseases of onion in all seasons are downy mildew, which can be sprayed with 25% methamethaline 500 times; The main insect pests are allium aphid and leaf miner fly, which can be controlled with pesticides such as aperium and avermectin.

1. Plant in the soil.

2. Watering some water, if possible, you can water some farm fertilizer, it is best not to use chemical fertilizer, which is not good for the human body.

3. Grass should be frequent, and if the weather is dry, water frequently.

4. When the seedlings grow out and have the thickness of the mouse line, they can be transplanted.

<> planting four seasons onions, to first select a good plot for deep turnover, and apply base fertilizer in it, generally the most suitable for planting in spring and autumn, spread its seeds evenly into the soil, infiltrate and wait until the seedlings grow stable after each hole 3-5 plants can be planted, and then the maintenance of four seasons onions need to be diligent application of thin fertilizer, but also do a good job in water management.

1. Soil preparation and fertilization.

Four seasons onion likes to grow in the fertile and well-drained soil of sparse pine, before planting, it is necessary to turn the selected plot deeply, and also need to apply a sufficient amount of decomposed organic fertilizer in the soil as base fertilizer to improve the fertility of the soil, so that the four seasons green onion can grow vigorously after planting.

2. Sow seeds at the right time.

Four seasons onion can be planted all year round, but it is generally best to sow in spring 3-4 months and autumn 8-9 months, the climate environment at this time is conducive to its germination and growth, in the summer planting needs to shade and cool it, if the winter planting four seasons onions, then it should be covered with a small arch shed to keep warm.

3. Planting method.

Before planting, the soil should be watered thoroughly, and then the seeds of the four seasons onion should be evenly sown into the soil, and covered with a thin layer of soil to keep the soil slightly wet, and soon it will be able to emerge and grow, after the growth of the four seasons onion seedlings is stable, it can be planted according to the method of 15-10cm, 3-5 plants per hole.

4. Maintenance management.

Four seasons onion planting needs to do a good job of maintenance management, it needs to be regularly loosened and weeded during its growth, but also need to apply thin fertilizer to promote its vigorous growth and development, the dry season needs to be timely watered to the four seasons of onions, the rainy season should pay attention to drainage, but also need to pay attention to the prevention and management of pests and diseases.

The planting season is sown in March --, April, and can also be sown in September and October, and the germination temperature is suitable at 13 20 C. The seeds are sown on the soil surface, covered with soil about 1 2 cm, watered thoroughly, when the temperature is suitable, it will begin to germinate in about 2 weeks, and the seedlings will grow slowly, and they can be transplanted and planted after germination about 4 or 5 weeks.

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.

According to the row spacing of 20 cm, plant spacing 10 cm transplanting, planting 4-6 plants per hole, spring onions, autumn onions can be appropriately sparsely planted, planting should be shallow, about 3 cm - 5 cm or so, after planting timely watering planting water.

In the spring, from March to April, plants are planted in well-drained soil.

Four seasons onions are suitable for growing in a warmer environment, and the temperature gradually rises in spring, which is more suitable for the growth of four seasons onions, so planting four seasons onions is best carried out in spring, and planting four seasons onions in spring from March to April can make the plant grow better. When planting green onions, it is also necessary to adopt the correct planting method.

First of all, you need to dig a row of soil trenches in the soil, and then you can place the selected green onion seeds in the soil trench with the tips facing up, and bury the seeds with an appropriate amount of fine soil, exposing only the parts of the long leaves. At the same time, it is best to control the spacing between seeds at about 10 cm when planting.

Planting alliums also requires the right soil. Four seasons onion is suitable for growing in the soil with rich trace element content and good drainage, so it is best to use sandy loam soil or humus soil with rich organic matter content and loose soil when planting four seasons green onion, so that the four seasons green onion can grow better.

The cultivation of all-season onions requires the selection of high-quality varieties, the use of fertile and loose soil, the application of nitrogen, phosphorus and potassium fertilizers, the control of watering, the management of colonization, and the control of pests and diseases. Planting time: March-April, July-August in the south, September-October in the north.

Cultivation Method:

1. Variety

Four seasons of green onions should choose cold-resistant, drought-resistant, heat-resistant, adaptable, white and long, non-tillering varieties.

2. Soil

Green onions need to use fertile and loose soil, with sufficient bottom moisture and pH.

3. Fertilization

Green onions like fertilizer and require balanced application of nitrogen, phosphorus and potassium. In the early stage of growth, more nitrogen fertilizer is required, and more phosphorus and potassium fertilizer are required in the later stage.

4. Control watering

Green onions like moisture, but the ability to absorb water and fertilizer is poor, the roots are mostly distributed on the surface of the soil, and there are high requirements for soil moisture, but the watering can not be too much, otherwise it will lead to root death.

5. Colonization management

Before planting, it is necessary to separate the size of the seedlings, remove the diseased seedlings, weak seedlings, too small seedlings and obviously bent seedlings, the plant spacing is 35-40 plants per meter, the row spacing is 1 meter, and the leaf surface and the planting ditch should be arranged in a vertical direction when planting.

6. Prevention and control of diseases

Green onions must be planted at intervals of 3-4 years with garlic, which can effectively reduce the occurrence of pests and diseases. If green onions are planted continuously for more than 15 years, it is easy to lead to the occurrence of diseases such as heavy crop disease, root rot, Verticillium wilt, and purple spot disease, which will affect the quality and yield of green onions.

Planting time

In the south, the allium is generally sown in March and April, but it can also be sown in September and October, and the allium in the north is planted in July and August in summer.

The planting time of the four seasons green onion is selected from March to May in spring or September to October in autumn every year. The planting method of the four seasons green onion: treat the seeds, select a good variety, soak the seeds to sprout, and sow them after they are exposed; Choose the soil, choose loose and breathable sandy soil or humus; Sow seedlings, control the spacing, sow seeds on the soil and water them.

Four seasons of onion can choose in the spring of March to May or autumn of September to October, during this period the temperature is suitable, basically stable at about 20, the climate is warmer areas can be planted all year round, and give sufficient light time, can improve the germination rate of four seasons of green onion after sowing.

1. Treat the seeds

When planting four seasons of green onions, it is necessary to choose the varieties with good growth and no disease and insect damage, and then soak them in warm water of 55 for 20 minutes, so that the seeds can absorb enough water, and then wrap the seeds with wet gauze, and place them in the environment of 30 for germination treatment, and then sow after the seeds are exposed.

2. Select the soil

Suitable planting soil, for the later growth of the four seasons of onion plays a key role, the four seasons spring is suitable for growing in the trace elements, and good drainage and air permeability of the soil, you can choose a loose sandy soil or humus, and before planting the soil disinfection, to promote the healthy growth of seeds.

3. Sowing seedlings

Dig a drainage ditch in the planting soil, it is best to control the spacing between the seeds to about 10 cm, then place the processed seeds on the soil ditch with the tip facing up, and then cover the part of the fine soil of 1-2 cm only showing the long leaves, compact it and water it thoroughly to keep the soil slightly wet.
