What should be prepared before transplanting green onions? When should I transplant it?

Before transplanting green onions, the most important thing is to level the land in advance and apply foot fertilizer, before and after the mango planting can be transplanted, the key is to have a suitable green onion planting, green onion planting to be dry and wet appropriately, reduce the damage to the roots.

Green onions come from semi-liquid areas and have a wide range of temperature adaptations. He loves the cold and can't stand the heat. Onions in the Yangtze River basin are usually sown in March-April and harvested in June-July.

It is also possible to sow seeds. From September to October, from April to May every year. During this period, the ungrown young seedlings are ** to the market, mainly to eat the young leaves.

Be careful when replanting shallots. Do not damage the green onion leaves. When the green onion is tall, the row spacing, width and base fertilizer of the green onion should be slightly increased, otherwise the green onion will fall off and the leaves will be damaged.

Pay attention to fertilization and insect control measures!

The best time to transplant green onions is in mid-June.

Preparation before transplanting green onions: convenient irrigation and drainage, thick tillage layer, uniform soil and miscellaneous fertilizer at the bottom of the ditch, and no need for frequent watering when transplanting.

The transplanting time of green onions is in the middle of June, and the transplanting work needs to be completed at the end of June. When transplanting, choose a piece of land with easy drainage, apply part of the base fertilizer after ditching, and break up the clods. Choose a plot with high terrain, good drainage and fertile soil, the best north-south direction, apply foot fertilizer, bottom fertilizer can be applied per mu 5 000 kg of farm fertilizer, 100 kg of phosphate fertilizer, 10 kg of urea, 15 kg of potassium fertilizer

Transplanting green onions is usually carried out at the end of May to mid-June each year, and the transplanting work should be completed before the end of June at the latest, and the green onions are generally sown in the spring, and the growth of green onion seedlings is already very stable in May, and the climate is more suitable for the growth of green onions in May, and transplanting can ensure that the green onions grow better.

Green onion is an indispensable vegetable and condiment in people's lives, green onion is also one of the most widely planted crops in rural areas, planting green onions can not only meet their own consumption, but also bring economic benefits to growers, planting green onions is not only to understand the growth characteristics of green onions and the law of fertilizer, transplanting is also a science, transplanting technology is good green onions can yield high.

Green onion transplanting time.

Transplanting green onions is usually carried out at the end of May to mid-June each year, and the transplanting work should be completed before the end of June at the latest, and the green onions are generally sown in the spring, and the growth of green onion seedlings is already very stable in May, and the climate is more suitable for the growth of green onions in May, and transplanting can ensure that the green onions grow better.

Green onion transplanting brother punch technology.

1. Site selection

Transplanting green onions first to choose a good planting site, it is best to choose a plot that has not been planted with green onions within three years, after the plot is selected, the first thing is to turn the ground once, and then clean up the debris in the plot, and then open a ditch in the north and south, and fertilize in the ditch.

2. Dig seedlings

Before digging seedlings, it is necessary to water the dust envy once, watering is to reduce the damage to its root system when digging seedlings, it is best to dig deeper, but do not hurt the new roots, after the green onion file shoots the seedlings to dig out, the weak seedlings, disabled seedlings, and diseased seedlings are eliminated, and the green onion seedlings are separated according to the height, thickness and size, and they can be planted after treatment.

Post-transplant management of green onions.

Green onion seedlings are relatively weak after planting, so at this time can not be exposed to direct light, to carry out a proper shading treatment, and then give normal light after the green onion seedlings resume growth, if you find that the soil is slightly dry, you need to replenish water in time, the soil is best to be in a moist state all the time, in addition, to ensure that the place is well ventilated.

First of all, we must pay attention to the crop rotation of the trapped family file, otherwise it will cause the lack of trace amount of Yuan Yuan Meng fertilizer, and Wang Chao and must go to the top dressing in time, green onions should not be too deep when planting seedlings, choose the onion method to plant green onions, so that it is more economical.

When transplanting, the green onion seedlings should be planted when they are about 25 to 30 cm high, and then they should be evenly exposed to light, and the depth of the ditch should be about 15 cm.

In the process of planting green onions, transplanting should be carried out with soil, and ridged planting should be carried out outside the periphery, so as to make the green onions of the Zen section thicker and longer. The quality of the green onion will also be better.

Transplanting time and method of green onion in the north: transplanting time, land selection, digging of green onion seedlings, planting method, post-management.

1. Transplanting time

Transplanting green onions is usually carried out from the end of May to mid-June, and the transplanting work should be completed by the end of June. Green onions are usually sown in spring, and the growth of green onion seedlings is stable in May, and the climate is suitable, at this time, transplanting and planting can ensure the growth of green onions, and it is also convenient to manage. If the transplanting time is too late and the temperature is too high, it is easy to hurt the green onion seedlings.

Second, land selection and land preparation

Choose a plot that has not been planted with green onions in three years and have easy drainage. After the plot is selected, the land should be prepared first, and the land should be turned over once to clean up the debris in the plot. Then the ditch is opened from north to south, the ditch is deep and the width of the ditch is 30-35 cm, and the distance between the ditches is 80 cm.

Bottom fertilizer should be applied in the ditch, just use farmhouse fertilizer.

3. Dig up green onion seedlings

When digging up green onion seedlings, you should water them in advance, which can reduce damage to the root system. It's better to dig deeper and not hurt the new roots. After the green onion seedlings are dug out, the weak seedlings, the disabled seepage seedlings, and the diseased seedlings are eliminated.

It is also necessary to separate the green onion seedlings according to their height, thickness, and size. After treatment, plant in the soil as soon as possible, do not leave it for too long, and try to keep the green onion seedlings fresh.

Fourth, planting methods

After the green onion seedlings have been processed and the plot is ready, it can be planted. The onion seedlings are planted directly into the soil, and the plant spacing is 3-5 cm, and the depth is basically the same as the depth dug before. Immediately after planting, water thoroughly to allow the roots of the onion seedlings to be tightly integrated with the soil, so that the growth will resume soon.

5. Post-management

After planting, green onion seedlings should not be exposed to direct light, and should be properly shaded. After the growth is restored, the clumps are withered and then given normal light. If the soil is found to be dry, it is necessary to replenish water in time, and the soil should be in a moist state for hail. In addition, it is important to ensure that the environment is well ventilated.

The specific method of transplanting and planting green onions is as follows:

One: Allium is a perennial herbaceous plant of the family Liliaceae. Bulbs solitary, cylindrical, sparsely ovate-cylindrical with an expanded base; The bulb has a white, pale reddish-brown skin, membranous to thin leathery, and does not break.

2. Growth habits.

Onions have strong adaptability, which is mainly affected by temperature, moisture, light, climate, soil, fertilizer, etc.

Three: cultivation technology.

Colonization 1Colonization period.

The planting period of green onions is not strict, and it can be planted from early June to early July.

2.Fine land preparation, application of sufficient base fertilizer.

Choose plots with high and dry terrain, deep soil layer, convenient drainage and irrigation, and fertile soil for cultivation. Before ploughing, 4000 kg of fully decomposed farmhouse fertilizer should be applied per mu or planted before the ditch, and 15 kg of urea, 20 kg of superphosphate or 20 kg of compound fertilizer should be mixed into the farm fertilizer in advance, and then deep raking and ditching for ridges.

Strict selection of seedlings and early planting.

Water once two days before the seedlings to ensure that the dry and wet seedlings are suitable for the seedlings, and the seedlings should be eliminated when the disease and residual seedlings are removed, and the strong seedlings will be graded and planted.

Reasonable colonization. The row spacing is 80 cm, the plant spacing is 3-4 cm, and it is advisable to plant 2-30,000 plants per mu.

3.Colonization method.

Generally, the method of draining onions and inserting shallots is adopted. Row onions are suitable for short white onions, and onion inserts are suitable for long white onion planting. The planting depth should grasp the principle of unevenness, that is, the heart leaves of onion seedlings should be 7-10 cm above the ditch surface.

Four: pest control.

The main diseases of green onions are downy mildew, purple spot, rust, anthracnose, sclerotinia and soft rot. The main insect pests are allium thrips, allium nematode disease, submarine flies, noctuidae and so on. No matter what kind of pests and diseases occur, it will seriously affect the good growth of onions, leading to the occurrence of pests and diseases.

Prevention and control methods. After the harvest of the previous crop, the stump and diseased leaves should be removed in time to reduce the source of pathogens.

Strengthen field management, timely watering and top dressing, promote plant growth, and improve their ability to resist diseases and pests.

After the onset of the disease, it can be sprayed with 80% dichlorvos EC 1000 times, aphid lice net 2000 times, 40% dimethoate EC 1000 times, 50% phoxanthion emulsifiable 1500 times, etc., sprayed once a week, sprayed 2-3 times.

The transplanting time of green onions in the north is from March to May in spring and October in autumn. The method can start from sowing seedlings, transplanting and planting.

1. Planting time

Green onions can be planted all year round, planting in the north is usually selected in the spring of March to May and autumn in October, spring sowing to choose the heat resistance, higher yield varieties, autumn sowing to choose low temperature resistance, good disease resistance varieties, conducive to overwintering and warming after the sprouts.

2. Planting method

1. Sowing seedlings: Northern green onions plough the soil before sowing, water enough water after the whole furrow, mix the prepared seeds with sand, and sow them in the soil.

2. Transplanting and planting: After the green onion seedlings grow, choose a plot with higher terrain, fertile soil layer and convenient drainage and irrigation, dig and plant holes according to the row spacing of 90x3 cm, plant a green onion seedling in each planting hole, and compact the soil after planting, so that the root system and the soil are in close contact and speed up the slow seedling speed.

Green onion planting and fertilization pay attention to digging Hengfeng

First of all, before transplanting, apply base fertilizer in the field, 250-300 kg of organic fertilizer, 40-50 kg of compound fertilizer, evenly mix with the soil, level and dig a trench, 10 kg of compound fertilizer can be applied at the bottom of the ditch, mix evenly, and prepare for transplanting.

Secondly, green onions have been growing slowly since they were first planted, but they grow quickly after the rainy season. In early autumn, the weather turns cooler, the old leaves gradually turn yellow and old, and new leaves continue to grow. This is a critical period for fertilization. We must immediately carry out fertilizer replenishment.

At this time, you can add some nitrogen fertilizer, generally 10 kg per mu, shallow hoe the surface soil, and water once. Two weeks later, the second fertilization, the use of compound fertilizer is better, about 50 kg per mu, combined with deep hoeing, and then watering.

In another month or so, we will apply fertilizer for the third time, that is, 50 kg of compound fertilizer, 15-20 kg of urea and 20 kg of potassium sulfate, and then water the soil. This will encourage the growth rate of the green onions, maintain a well-proportioned body, and make them thick until harvest.
