When to pluck green onions? When to shave shallots

Winter onions are generally planted in autumn and harvested after winter. Due to the problem of planting time, this green onion can meet the market demand of winter and spring onions. The second is the overwintering green onions, which are generally planted on protected land, and the seedling time is the same as that of using green onions in winter, which is carried out at the end of October in autumn and harvested from April to May next year.

Autumn late-maturing shallots are generally planted at the end of May each year. The harvest season generally runs from late autumn to early winter, that is, from November to December every year. The more onions there are in summer, the summer onion planting time is generally from the end of January to mid-February each year, and the harvest time is from the end of July to the beginning of August.

How to determine the best time to harvest green onions: In addition to judging the best harvest time of green onions according to the different planting times above, you can also judge the growth status of green onions. During the harvest season, the green onion leaves on the outside stop growing, and the leaves have begun to take on yellow and green colors, but there is no drying out, and this is the most suitable time for harvesting.

Picking green onions is still a technical job, it is easy to see, but without experience, it is very easy to break the green onions, so it is good to be careful during harvesting or need to be careful.

Gently pull out the green onion plant with your hand. Do not pull and pull violently during harvesting to avoid damaging the false stem, pulling off the stem disc or breaking the root and reducing the quality of the commercial onion. After harvesting, the green onions should be shaken clean of the soil, graded according to the purchase standard, 4-5 intact leaves in the middle should be retained, spread in the ground, and every two ditches of green onions should be combined into a row, and dried in the ground for 2-3 days.

When the leaves are soft, the fibrous roots and the white surface layer of the green onion are semi-dry, remove the dead leaves, grade and bundle, divide the rope into 3 solid ways, can not be tied tightly, prevent the flattening of the green onion leaves, 7-10 kg per bundle. Do not stack them casually to avoid heat.

Rot. Green onions should also be harvested to avoid morning frosts. After frost, the leaves are straight and brittle, easy to break and lose water, and are also easy to be infected with diseases and rot. In this case, it can be harvested temporarily and harvested when the temperature rises during the day and the green onion leaves thaw.

1. Winter green onions are generally planted in autumn and can be harvested after winter. Green onions are generally marketed in winter to meet the needs of market groups.

2. The planting of wintering green onions is generally carried out on the protected land, and its seedling time is the same as that of winter green onions, which is carried out at the end of October and harvested from April to May of the following year.

3. The delayed planting of green onions in autumn is generally planted at the end of May each year, and harvested from late autumn to early winter every year, and the specific time is from November to December of each year.

4. Summer onions are generally planted in the winter of each year, the specific time is from January 15 to February 15, and the harvest is carried out from July 15 to August 15 every year.

Green onions, when are they sent? When there are eight major species, it is generally said in the Northeast. At. Green onions can only be pulled at the end of September and early October, otherwise green onions, green onions are drought-resistant, drought-resistant. Plants bothered. Large insects will appear hollow inside.

As the saying goes, onions in July and empty in August. That is to say, the green onion should be pulled out in July, and the person has not put it on August 15, the green onion is empty, and the quality is not good.

This refers to what the lunar calendar says.

It is best to harvest green onions when frost falls, and they are very full and ripe, which is conducive to winter storage.

The harvest period of green onions is between the beginning of winter and light snow. When harvesting, use a long and narrow strip of pickaxe 5 cm away from the green onion, remove the soil to expose the green onion white, grab the lower part of the green onion white with your hand and pull out the green onion tree, shake off the soil, dry for about half a day after grading, remove the diseased, disabled, weak and small trees, and put the root of the green onion that meets the standard, and bundle it into a bundle of about 5 kg with straw, into a bundle **.

Onions are not shade-tolerant, do not like strong light crops, the light intensity requirements are moderate, after normal vernalization, light intensity, light time can grow and bloom normally regardless of the length. In each growth period of green onions, suitable light conditions can promote the growth of plants, make green onions white and thick, and improve yield.

Onion has strong adaptability to the soil and is suitable for planting in the soil with pH value, but because of its short root system, small root group and underdeveloped, it is advisable to choose the plot with fertile soil, deep soil layer, suitable sunlight and good drainage and irrigation. If the soil pH is too high or too low, it will hinder the germination of seeds and affect the normal growth of green onions.

Before and after the frost, it should be slightly dried on the ground after planing, and the dead leaves and soil should be removed and bundled for long-distance transportation or retail with planing.

Summary. According to the sowing season and temperature, the seedling emergence time of green onions is divided into: 1. Sowing 9 to 13 days in spring from March to April can be seedling; 2. In the summer and autumn from May to September, the seedlings will emerge in about 8 days; 3. When raising seedlings with mulch, the temperature should be controlled at about 18, and the seeds can emerge 6 to 8 days after sowing.

When the emergence rate reaches 60%, the mulch film is removed in time, and the film is too late, and the seedlings are weak. After the seedlings are straightened, they can be watered 1 time to make the cotyledons stretch and take root to stabilize the seedlings, and then water 1 2 times according to the soil moisture. Top dressing 1 2 times during the whole seedling stage, mainly with fast-acting compound fertilizer, to promote the healthy growth of seedlings.

Do you use a cover mold to plant shallots in August?

Can't you get out with watering?

There is no need to cover the mold in August.

If the ground is dry, it needs to be watered.

To plant shallots, you need to choose loose, fertile and breathable soil, and the soil needs to be deeply cultivated and disinfected before planting. 3. Planting: Choose healthy shallot seeds, plant them in the soil at a certain distance, and then cover them with a thin layer of soil.

Maintenance of shallots.

After the shallots emerge, the seedlings need to be properly thinned and supplemented, and the seedlings that do not grow well need to be pulled out, the weeds in the soil need to be cleaned up when the seedlings are just unearthed, and the water and fertilizer need to be properly supplemented, which is conducive to the growth of shallots.

Shallots like a warm growing environment, the suitable temperature is 12 20, when the outside temperature is too low, you need to do a good job of cold measures, when the temperature is too high, you need to sprinkle water around the plant to cool down.

During the growth of Weilingkai shallots, it is necessary to replenish nutrients in time with hail, and the nutrients are insufficient, and the plants grow poorly, but pay attention to the amount of fertilizer should not be excessive, otherwise it will affect the yield of shallots, and water can be properly replenished after fertilization.

First, the appropriate harvest period of green onions.

The harvest period of green onions can be determined according to the growth of green onions and the demand of the market. Generally, the harvest period as fresh onions is in October to November, which is the highest quality and yield of green onions. If used as a storage of green onions, by December, due to cooling and frost in the northern region, the green onion leaves turn yellow and wilt, the water is reduced, the mesophyll becomes thin and drooping, and most of the nutrients are loosened into the false stem, so that the false stem becomes full, and the garlic taste at this period is still very good, but due to the small water content of the tubular leaves of the green onion, the yield of the green onion harvested in this period will be lower, but it is more resistant to storage.

Second, the method of harvesting green onions.

Harvesting green onions can be done manually and mechanically. When harvesting, use a green onion shovel to cut the green onion root from one side of the green onion ridge, turn the soil to the green onion ditch, expose the green onion root, and gently pull the green onion to the side of the ridge.

As a fresh shallot for export, the harvesting method is similar to cutting leeks, using a knife to cut 1 2 cm from the ground, and the harvesting of shallots should pay attention to protecting the stems and leaves to improve the commerciality.

During the harvesting process of green onions, do not pull and pull violently, so as not to damage the false stem, pull off the stem disc or hurt the roots, break the roots and reduce the commerciality and storage resistance.

3. Problems that should be paid attention to in the process of green onion storage.

In the cold winter, the temperature is too low, and the stored green onions are frozen into popsicles, which can not be turned at will. Frozen green onions can be restored to their original state by simply handling them with care and slowly thawing them in an empty or cellar. If it continues to be stored, it does not need to be turned over, and it will return to its original state as the temperature rises.
