What kind of cultivation methods do you have for shallots, and what kind of requirements do you have

Seacreed squirts like sunlight, also tolerate semi-shade, cold-resistant, afraid of direct sunlight in summer, good humid environment, and the leaves remain green after heavy frost in winter. The bulb has a dormant habit in summer, and the bulb has strong meristem and high reproductive coefficient. Breeding:

Commonly used for propagation by balling and seeding. Natural bulb propagation, digging up the bulb in August and September, planting according to the size of the grading, after a planting for several years, when the bulb is crowded, then dividing the bulb. Sowing and propagating, seedlings need to be cultivated for 3 to 4 years before flowering.

Cultivation: Robust growth, tolerant of extensive management, fertilization once every half month, the soil should be loose, moist and well drained. After flowering, the residual flower stalk should be removed, and the flowering will be more successful in the next year.

The bulb should be stored at a temperature of 25 and should be dried and ventilated. Pests and diseases: The disease has mosaic and leaf disease, the virus is transmitted by aphids, and it can be sprayed with 800 times of rotenin to prevent and control winter and spring management

In winter, pour frozen water before the cold snap arrives. After the great cold, the beginning of spring is coming, and the temperature in the north is gradually rising, so it is necessary to water and fertilize in time. If the temperature is low in the early stage, you can water a small amount of water according to the moisture to prevent flooding.

After the sting, the earth was thawed, combined with watering, and 30 kg of urea per mu was applied. In order to harvest in advance, farmers with conditions can build a small arch shed before the beginning of spring, so that the temperature is about 20, and if it exceeds 30, it is necessary to ventilate in the morning in time. After the temperature warms, the growth rate of green onion seedlings accelerates, and it is easy to sprout buds at this time, and the flower buds are removed in time when the bud height reaches 3-6 cm, so that the green onions are transformed from reproductive growth to vegetative growth, so as not to reduce the quality of green onions.

I don't have any kind of request. Let's just plant it in seasons.

Shallots can be grown in sandy loam and clay loam. Shallots have a strong ability to survive and integrate into the soil, which can meet most of the natural soil environment, such as sandy loam or clay loam. However, the advantages and disadvantages of different soil qualities are different, and the presentation of shallots is also different in different soil qualities.

Based on my work experience, I know that the most suitable soil for growing shallots is a loose clayey loam with particles. Grown in this type of soil, shallots are of higher quality and yield.

Which soil is better to use to grow shallots?

It is better to grow shallots in loose soil and powdery clay loam. Loose soil is beneficial to the growth of shallots, and loose soil is beneficial to the entry of gases and aerobic respiration at the roots of shallots, and on the other hand, it is also beneficial to the maintenance of water. Compared with plate soil, loose soil has a stronger water storage capacity and is very friendly to the growth of shallots.

The granular soil has an effective water and fertilizer storage capacity and has good air permeability. The loose and porous structure of the soil is suitable for growing shallots. The cohesive loam soil has less sand content, fine soil quality, rich and colorful nutrients, slow leakage, strong water-retaining ability, and is more suitable for planting shallots.

How to grow shallots

Sowing: Spring or autumn is the best time to sow shallots, choose rich and soft soil before sowing, and bring a suitable natural environment for the growth of shallots. The day before planting, the soil should be adequately watered and fertilised. It's all about pre-planting preparations.

Transplanting: Before sowing, soak the shallots in 55 water for about 20 minutes, take them out to dry and plant them in the soil. The shallots look quick under the right standards.

About 40 days after planting, if you find that it looks congested, you can plant a part of it first. Before planting, it is also necessary to pour the new soil with mountain spring water, and plant the shallots on the cover plate with fine soil and wait for them to grow.

Feeding: Only the leaves of the shallots are plucked when picking, and they do not have to be uprooted. Then the shallots can grow out again and be picked several times.

The cultivation of shallots is mainly spring ploughing and autumn planting, it likes wet and cold, and the suitable growth temperature is about 12-22 degrees. Shallots should be planted in the leeward of the rising sun, which is suitable for growing in rich, loose, strong drainage pipes and thick soil. Select seeds with high yield, high drought resistance and good quality, mix seeds in advance, promote germination treatment, spread the seeds evenly into the soil, cover the soil and irrigate, ensure the temperature after sowing, water on time, and wait for the bud to sprout.

I think you should choose some sandy soil with good drainage, because if the soil is too wet, it is likely to cause the shallots to rot.

You should choose some soil with good air permeability and water absorption, and it is best to choose some alkaline soil, so that the grown shallots will be particularly strong.

I think you should choose soil with acidity, soil with high humidity, soil with high temperature, soil with wide soil, and fertile soil.

You should choose some fertile soil, the soil is slightly drier, so that it is not easy to grow insects, and the growth may be better.

You don't need special soil to plant green onions, sprinkle onion seeds in the soil at the beginning of spring, cover the soil with your feet.

Four seasons of green onions can be harvested for 2 to 3 years at a time, generally sown in months or months.

Cultivation method. 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.

Cultivation techniques. Fine land preparation, application of sufficient base fertilizer, four seasons onion should be grown in loose and fertile soil, 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.

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.

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, so as 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.

Thin fertilizer and light application, moist soil, shallow distribution of onion roots in all seasons, weak absorption, so not tolerant to thick fertilizer, not tolerant to drought and flood, and weeds are less competitive, field management must achieve thin fertilizer and light application, rain drainage and dry irrigation, and moist soil. 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.

Prevent diseases and insects, and reduce pollution.

Actually, my father planted green onions, and his furnace ash also grew green onions.

The main thing is that the porosity and air permeability are good, and there are not too many requirements in other aspects, whether it is the role of acidity and alkalinity, the green onion itself can grow in any kind of environment, and there is basically no special requirement for the environment.

Green onions must have sufficient water when planting, do not like thick fertilizer, the soil should be moist, the ventilation should be good, and when planting, the distance should be appropriately opened.

The requirements for the soil are particularly strict, it must be guaranteed that there are sufficient nutrients, and we must pay attention to the ventilation is particularly good, there must be a certain humidity, we should regularly fertilize and water them, increase the gap between them, do not get too close, and maintain sufficient sunlight to facilitate the growth of green onions.

Green onions need to be fields with deep soil layer, high organic matter content, convenient drainage and irrigation, and convenient transportation. Green onions should have no requirements for soil, but they require deep soil and easy watering and drainage. Green onions are widely adapted to soil conditions and can be cultivated from sandy loam to clay loam.

Cultivated in sandy loam soil, the green onion is rough and loose, the outer dry film has many layers, it is not brittle and tender, the spicy taste is heavy, and it is not resistant to storage and transportation. Green onions cultivated in clay soils are white and slender, and the yield is low. Soil with loose soil, deep soil layer, strong permeability, and high fertilizer and water retention capacity can obtain high yields.

Green onions require neutral soil, which is the most suitable for the growth of green onions. The pH range that can be adapted is that onions are planted in acidic soils, and quicklime should be applied for soil improvement. Green onions should not be cropped continuously, and it is best to rotate crops at intervals of 3-4 years.

Shallots can be grown in sandy loam and clay loam. Shallots have a strong ability to survive and adapt to the soil, and can adapt to most soil environments, such as sandy loam or clay loam.

Alkaline soil should be chosen, and it should be watered and fertilized in a timely manner, and it is also necessary to ensure that the soil is permeable, and it is also necessary to ensure that the soil is fertile, and it is also necessary to maintain sufficient light.

Although green onions are water-loving crops, they should never be waterlogged in the field, especially during the high temperature stage. Water accumulation in the field is that it will solidify the soil, and the air permeability will become poor, which is not conducive to the growth of the root system In addition to loosening the soil, the water will be properly controlled during the long root period, and every year it will pull up the organic fertilizer saved by themselves and sprinkle it in the ground, on the one hand, it can provide long-term slow-acting fertilizer, on the other hand, it can also improve the characteristics of the soil that is not too loose, and the changed soil is still more suitable for planting green onions. , and even infect with various pests and diseases.

The second is in hot weather.

Standing water in the field is easy to "take root".

The soil quality of planting green onions, of course, is good for the loess in the northwest of our Gansu Province, and the loess here is still relatively "barren", of course, this is also inseparable from the characteristics of the green onions themselves and some trace elements of the loess itself.

and nutrients, the two can be described as "complementing each other".

The requirements for the environment and soil quality are not high, and it can be planted in desert areas. If you want to say that the soil quality is good for planting green onions, of course, the fluffy soil is the best, such as fertile black soil and sandy soil, both of which are fluffy soil, that is, loose soil. Due to the high sand content in the soil, the space is propped up.

This can reduce insect pests, reduce the growth of weeds, dry for a few days, sprinkle fertilizer, fertilizer is best animal manure, ridge planting, green onions are generally planted in May, regular watering, soil, regularly fill both sides of the green onions so that the green onions are relatively long and <>

At the seedling stage, the seedlings should be interspersed 1-2 times, and the weak seedlings that are too dense should be removed, and the seedling spacing should be 7-10 cm, and weeds should be removed. 3. Planting Green onion planting is generally in (early June) to the summer.

early July). When the onion seedlings grow to a height of 30-40 cm and a transverse diameter of 1-cm, it is suitable for transplantation. The plant is delicate, white and slender, and the yield is low.

Practice has proved that in order to obtain high quality and high yield, green onions need to choose dark brown clay loam soil with loose soil texture and granularity, and choose plots with deep soil tillage layer, rich organic matter and strong fertilizer and water retention ability for planting.

Planting green onions should choose fertile soil, soil with sufficient moisture, only during the planting period, green onions can grow particularly well, and the yield will be particularly high.

In fact, it is more suitable for planting in sandy soil or clay soil with more fertilizer and moist soil, in fact, green onions are better planted and there are not too many requirements.

2. Soil: When planting green onions, it is necessary to provide them with deep and fertile soil that is convenient for drainage and irrigation.

3. Watering: After the green onion emerges, it should be watered according to the wall condition of the soil to avoid rotten roots.

The planting time of shallots is usually in autumn, and it can be planted in autumn and winter in southern China, and soft, nutritious and well-drained and permeable soil can be used for planting; Give it some scattered light every day, and it will grow well; It is relatively cold-tolerant, and the temperature at the germination stage is controlled at 13 -20 at the best time, and the temperature above 28 degrees Celsius will reduce its growth rate; Because the root system is relatively sparse, the water requirement is not very sufficient.

Seedling: Choose plots with good drainage and fertile soil for seedlings, do a good job of soil plowing before planting, and apply enough fertilizer to ensure that the seedbed soil is loose and has good drainage. After the emergence of green onions, do a good job of water and fertilizer management at the seedling stage to keep the soil moist.

Fertilization: Use about 5 kg of urea per mu for top dressing, and start transplanting and planting work in late October when the green onions grow. Do a good job of soil plowing and fertilization before transplanting, control the depth of tillage at about 25 cm, use 3000 to 4000 kg of well-rotted organic fertilizer per mu according to soil fertility, and use about 15 kg of compound fertilizer.

Field management: first of all, the management problem after transplanting, pay attention to check whether there is a lack of seedlings and dead seedlings in the field after transplanting, timely replenish the seedlings, reduce weeds in the field, and then water and fertilizer management problems, watering according to the soil and seedling stage, and stop watering about 20 days before the harvest of green onions. In the growth stage of green onions, a total of 4 to 5 times of fertilization, according to the growth of green onions, fertilization should be carried out, and finally attention should be paid to the control of green onion diseases and pests.

Hello, I have seen your question, please wait a moment, I am sorting out the answer for you.

Before planting, be sure to choose the varieties planted according to the climate of the region, you can first do relevant research on the basic situation of local green onion planting, and then choose some high-quality and high-yield, and have a good market for planting. 2.Fertilization of the land.

Green onions are not very demanding when planting, they only need to be in sufficient light and close to a water source suitable for watering. When planting, choose plots with rich organic matter in the soil, turn at least 30 cm deep when acquiring land, and clean up the weeds and pest residues contained in the soil, and finally choose the right fertilizer for fertilization. 3.

Scientific planting. There are three main ways of green onion planting, which are planting propagation, branch propagation and bulb propagation. The most suitable time for planting is around May to June every year, when planting should be strictly in accordance with the interval of 30 cm per row of ditch for strip sowing or strip planting, the interval of each plant is about 5-8cm.

It must be noted that the ground must be watered thoroughly before the end, so as to improve the survival rate of green onions.
