How to grow small onions to achieve high yields? What s the best way to do it?

Green onions, also known as green onions or small chives, are a key daily seasoning and are the most widely cultivated in southern China. The roots of the onion are shallow, the tillering power is strong, the rhizome is not particularly large, the coat is slightly dark purple, the flesh is milky white, and the leaves are tubular and hollow. According to the growth habit of flowering, its species can be roughly summarized into three categories:

The onion that blooms and bears seeds is like a snow onion, and it is also called a four-season onion; The onions that bloom and do not bear seeds are like red green onions; Green onions that do not bloom and do not bear seeds, such as white grass shallots, fine-leaved chives, etc. The growth and development of onions stipulates that the soil layer is loose, the organic matter content is high, the water retention and fertilizer retention effect is strong, and the drainage pipeline is excellent.

Onions can be resistant to poor sunlight exposure, suitable for interplanting, and can also be planted on the ground in front of the house, or in the courtyard flower pot, which is convenient to take anytime and anywhere. There are two types of species selection, namely, commercial planting and self-carnivorous planting. If you choose to plant commercially, you should use flowering and seed-bearing onions, that is, snow shallots.

This is because the shallot plant is relatively large, has strong tillering power, is early to perfect, has a high production capacity, and can be multiplied with seeds, and the disadvantage is that the aroma is light; And for home use, it is used white grass onion or fine chives, this kind of green onion growth and development time is long, and does not flower and set seeds, the fragrance is strong, defects to be bred with underground rhizomes, and it is difficult to store seeds.

Planting green onions that bloom and bear seeds for a long time, propagated with seeds, can be planted in the beginning of spring and summer, and transplanted with seedlings. The non-seeded onions are bred with stored rhizomes and planted in mid to late August. Moderate access to onion in the case of immediate supply of liquid fertilizer, the tillering force is stronger, therefore, must continue to be obtained by intermittent allocation or fiber cutting, and can also be obtained by cutting leaves, otherwise, it will endanger the balance of sunlight and nutrients between plants, so that the plant becomes old and the production is reduced.

Onions like damp and cold, strong cold resistance, low requirements for illumination, suitable for growth of the ambient temperature of 12 23, under the high heat and strong light of about 25, the speed of aging accelerates, the production volume is low, and the quality is reduced. At ultra-low temperatures within -5, growth is slow. In spring and autumn, the plants grow and develop luxuriantly, and the leaves are in full bloom.

It can grow and develop normally in clay and sand, and has a wide adaptability to soil quality. The roots are shallow and not tolerant to drought and waterlogging, so they need to have a moist soil layer and good irrigation and drainage standards. Cultivation Techniques:

In the field management work of green onion, topdressing is the leading work, and soil hoeing, irrigation and irrigation are carried out, and the loosening of the soil is softened. Forced fertilizer is dominated by fast-acting base fertilizer. , from the plant to 12 13 cm gradually, top dressing 1 time a month, to top dressing 3 4 times.

Watering for 1 day per month, and the frequency of watering can be moderately increased in dry days. After fertilizing 2 times, gradually loosen the soil, a total of 2 3 times, the general loosening work is carried out with fertilization, in other words, to loosen the soil after fertilization, each time the deep layer of the loose soil is not suitable for too deep, in order not to cultivate the most suitable onion roots.

Pay attention to the outside temperature, keep the temperature at about 20 degrees, don't let the temperature be too high, and at the same time water in time to maintain the humidity of the soil.

It is best to plant green onions in spring and autumn to achieve high yields, because the temperature at this time is very suitable for the growth of small green onions.

At the time of planting, some sheep manure can be used to fertilize it, so that high yields can be achieved. Fertilization and watering should be carried out frequently, and attention should be paid to protection, as well as to the disinfection and sterilization of the soil. Pay attention to disease prevention.

Speaking of shallots, I believe everyone is familiar with it, it is a vegetable that we often eat in our daily life, and we add some shallots when cooking food, which can also make the taste of food more delicious. The method of growing shallots is also very simple, many people grow shallots at home, and there are some tips if you want to achieve high yields of shallots.

First, although shallots are easy to plant, they are also more heat-resistant and cold-resistant, but shallots prefer to grow in a cooler climate, and the most suitable growth temperature for shallots is about 20 26, if the temperature exceeds 28 degrees, the growth of shallots will become very slow. If it is in summer, we can also take some shading measures for the shallots, because in summer, the sunlight is very strong, strong light and high temperature, which is not conducive to the growth of shallots, and it is easy to make the shallots age.

Second, the root system of shallots is very shallow, so when we plant shallots, try not to plant more than 6 cm in depth, generally about 4 cm to 5 cm, and the row spacing of planting shallots can also be appropriately decided according to our own soil and terrain. After planting the shallots, water the shallots in time and try to keep the soil moist enough. Because the root system of shallots is very shallow, it will be poor in terms of absorption, so we don't need to apply too much fertilizer to shallots when planting, especially some raw fertilizers that are not fermented, which must not be used for shallots, which will affect the growth of shallots.

Third, when we plant shallots, we should also pay more attention to watering, do not water the shallots, which will also make the soil where the shallots are planted waterlogged, and the water accumulation time will easily lead to the rot of the roots of the shallots. Although shallots are very drought tolerant, they are not waterlogged, so we must control the amount when watering, and never flood with water.

When planting shallots, it is necessary to choose the right planting time, make a very clear understanding of the growth habits of shallots, choose the soil suitable for the growth of shallots, and water shallots frequently; You can choose some fertile and loose soil to plant shallots, plant shallots before and after Qingming, keep the growth temperature of shallots at the right temperature and humidity, and control the amount of watering shallots, so as to improve the yield.

Be sure to pay attention to the termination time, but also pay attention to the temperature of growth, and the amount of watering must be appropriate; When watering, water after the soil is dry, choose fertile, highly drained soil for planting, and be sure to choose fertilizer with more trace elements for fertilization.

The first point is to find a good place, and the shallot must be moist soil, and the second point is that the best way to increase the yield of this plant is to do a regular watering, so that is the most important thing.

Topdressing. After the seedlings are slowed down, a small amount of top dressing can be carried out in combination with irrigation, 5 kg of ammonium nitrate per mu, 15 kg of urea in two waters, and 15-20 kg of ammonium nitrate in four waters. Spray potassium dihydrogen phosphate 2-3 times throughout the growth period.

There are many varieties of onions, and unsuitable varieties cannot be blindly introduced, so as not to cause economic losses. Onion seeds are seeddressed, and wilted pests and pests are picked out before sowing and then hung in the sun for two days to control the spread of the disease. Onions are greened through vernalization, if the overwintering seedlings are too large.

In the second year, the moss will be extracted in advance, and the leaf sheath will not expand and form a bulb. Onion root distribution is shallow, weak absorption capacity, not resistant to water stains, easy to grow crazy when humidity is high, and it is better to contain sandy loam soil with more organic matter and strong water retention. Stem During the vegetative growth period, the stem of the onion will be shortened to form a flat and round cone - the stem disk, the lower part of the stem disk is the heel, the root is born on the heel, and the heel tissue of the mature bulb usually decays and hardens.

It can block the entry of water into the bulb stem.

To increase onion yields, we choose sandy soils whenever possible. If you want the color of the onion to be good and resistant to storage, it is best to choose a clay soil. No matter what we are growing, we have to choose soil with a lot of organic fertilizer, so that the plants have sufficient nutrients.

In such an environment, it is also conducive to the expansion and high yield of dripping bulbs. In addition, its root system is underdeveloped, the absorption capacity is weak, but the growth period is long, the yield is large, the nutrient demand is large, the demand for potassium, nitrogen, phosphorus, calcium is relatively large, we should start from the following nine aspects when planting onions.

Planting time in November need to be planted, add 4000 kg of farm fertilizer per mu, use 100 kg of diammonium phosphate, keep the row spacing at about 15cm, and then need to cover the mulch, so that you can better winter.

Sow seeds at intervals to ensure that each onion receives sufficient nutrients.

During the planting period, you must water the onion more, apply more organic fertilizer to it, and then spray the onion with insect-proof pesticides in advance, so that the planting can be very high-yielding.

In order to ensure the germination rate of onion seeds, it is best to carry out a germination test before sowing to determine the amount of seeding, and then soak the onion seeds in cold water for 12 hours, germinate under the condition of 20 22, rinse with water once a day, and sow in time when the seeds are exposed, otherwise it will affect the sowing.

Shape strong seedlings. Shallots can be planted from mid-September to early October, and the soil layer should be loose and rich, with strong water retention, and the soil resources that have not been planted with onions, garlic, vegetables and fruits in the past 2 or 3 years should be used as seedbeds。One acre of field needs seedbed (about 35 square meters) and seed amount.

The seedlings should be fertilized with the soles of the feet, made into rice (even ditch) wide furrows, watered thoroughly, sown with dry seeds, and covered with fine soil or scorched sand ash after sowing, so that the seeds cannot be seen. After covering the soil, you can use a 100ml sprayer per mu with 33% weeding (also known as field supplement) herbicide, which can control weeds in seedling land with high efficiency. Then cover with a layer of hay or shade film, which is beneficial to hydration, moisture, moisture, waterproof, and rainproof, and the seedling field should continue to keep the soil layered and moist and cold.

About 60% of germination is enough to remove the overburden. According to the supervision of fertilizer liquid, Beichong ant shapes young seedlings of appropriate age.

It not only prevents the seedlings from looking very large, resulting in early mossing, but also prevents the seedlings from growing and developing poorly to survive the winter. Onion seedlings of moderate size have about 4 leaves, a plant height of 20 25 cm, a leaf stem diameter of 6 7 mm, and a single tree weighing about 5 grams. The shallots are string-shaped underground stems with few root hairs, and they are mainly found in 15 cm of cultivated soil.

The stem muscles atrophy, called the "disc stem", have leaves on it. The leaf is hollow, the cross-section is half-moon-shaped, composed of two parts, petiole and tubular leaf, standing up and growing and developing, imitating the burial of the leaf stem sleeve to form a "false stem". At the bottom of the leaf stem, the underground stem is oblate, spherical or oblong, and the skin is dark purple, yellow or greenish-white.

Capitate inflorescences, with 200 1300 grasses, cross-pollinated. Pod. Seeds are shield-shaped, black-gray, germination rate 3 g 4 g.

The seed life is one year.

Generally, it is more suitable to pre-vaccinate in September and October. The seedling site should choose a loose and rich sandy soil layer or new land that is convenient and fast to irrigate, and has not been planted with onions and garlic. Before planting, it is necessary to turn the ground delicately, apply foot fertilizer, and plant it into a flat furrow.

Before planting, it should be soaked in warm for 24 hours, dried and mixed with dry crushed soil layer and sown. 1 mu needs to be planted in a seedbed of 70-75 grams, covered with fine soil after sowing, and then replaced with weeds to cover it, rainfall cleaning and direct sunlight from natural light. After covering the grass, apply dilute manure water, and drip insecticide drugs on the perimeter of the furrow, and remove the covering weeds after the seedlings are excavated.

During the pre-seedling period, every 5-6 days after drenching dilute manure solution, the seedling stage can be transplanted in about 40 days.

Choose the ground on the fat shallots to avoid continuous planting, planting should choose the front stubble planting eggplant fruits, melon and bean products, late rice in the industrial park, especially loose and rich sandy soil layer or new land planting is better. 1 mu of soil disinfectant with 25kg quicklime powder before plantingAnd use 1500-2000kg of high-quality well-rotted soil fertilizer as the base fertilizer. Furrow planting, furrow depth 80-100cm, furrow height 25-30cm, furrow surface soil stratification to loose, fragmented, flat.

When planting, care should be taken to keep the soil at a certain temperature and humidity, and attention should also be paid to watering and fertilizing.

It is necessary to water in time, pay attention to the planting time, and also pay attention to the outside temperature, and be sure to choose a better seed for planting.

In the process of planting, you can water and fertilize more, and pay attention to the control of the situation, but also pay attention to the management of the fruit Lu Meng, and pay attention to the temperature control, so that you can raise the bridge early to achieve high yield.

2. Cultivate strong seedlings.

Generally, it is better to sow seedlings from the end of September to mid-October. The seedling site should be loose and fertile, convenient for drainage and irrigation, and has not been planted with onions and garlic sandy loam soil or new land. Before sowing, the land should be carefully prepared, the bottom fertilizer should be applied, and the base should be sown into a flat furrow.

Before sowing, soak in warm water for 24 hours, dry and mix dry crushed soil to sow evenly. 70-75 grams per mu need to be sown in the seedbed, covered with fine soil after sowing, and then covered with weeds to prevent rain erosion and direct sunlight. After covering the grass, apply dilute manure water, sprinkle insect repellent drugs around the furrow, and remove the covering weeds after the seedlings are unearthed.

During the seedling period, it is drenched with dilute rotting manure water every 5-6 days, and the seedling period can be transplanted in about 40 days.
