What are the environmental requirements of chives, and what is the planting season and daily managem

Chives have certain requirements for the temperature of the environment, soil and fertilizer. It is best to plant in the spring. Regular application of organic fertilizer to promote the growth of plant rhizomes.

What are the environmental requirements of chives? What is the planting season and daily management of chives?

1.Requirements: chives like cool climate, cold tolerance and heat resistance are strong, germination temperature is 13-20 degrees Celsius, stem and leaf growth suitable temperature 18-23 degrees Celsius, root growth suitable ground temperature 14-18 degrees Celsius, slow growth above 28 degrees Celsius.

Due to the shallow distribution of the root system, the water requirement is less than that of green onions, but it is not drought tolerant, and the suitable soil moisture is 70%-80%, and the suitable air humidity is 60%-70%. Medium intensity is required for light conditions, and the tissue is easy to age, the fiber increases, and the quality deteriorates under strong light conditions. It is suitable for planting in loam and heavy loam plots that are loose, fertile, and easy to drain and water.

2.Because chives are cultivated in a flat furrow, if the soil is too clay, the soil is easy to harden due to watering or rain, and the root permeability is poor, which will cause poor growth of chives and even white onions. So try not to choose soil with too much viscosity in the soil and strong alkaline, other soils can adapt to the growth of chives.

2.Temperature: Chives are cold-resistant crops with strong cold resistance and weak heat and cold resistance, suitable for warm, cool and humid growing environments.

The growth period is 15 20, and if it exceeds 25, it will not grow well. The tissues of onion leaves will become older, the fiber will increase, and the onion leaves will become soft and tender, and the quality will deteriorate.

3.Chives are suitable for warm climates and are suitable for growing at 15-25 degrees. It is generally cultivated in spring and autumn in North China.

Generally, spring is suitable for planting around the Qingming Festival, and autumn is more suitable for planting at the autumn equinox. In addition, chives can grow well in low temperatures, so they also have the conditions for wintering. Many people grow chives slowly because the temperature of the environment in which chives are grown is too high.

When it comes to growing crops, many people think that constant watering can make crops grow faster and better, which is obviously a misunderstanding. The cultivation of chives does not require much water. If there is too much water, the root system of the chives will rot, so we need to water properly according to the drought resistance of the chives, and the watering time should be controlled in the morning.

It is okay to plant in the spring, be sure to water it in time, ensure the fertility of the soil, and pay attention to transplanting and planting. Proper topdressing can be done.

The requirements for the environment of chives are: soil environment, temperature, light, soil moisture, short growth period of chives, and few pests and diseases. During the growing season, as long as the soil is moist and thin fertilizer is applied frequently, you can ensure that the green onion plant chives can be guaranteed.

Therefore, the management is relatively simple compared to the cultivation of chives. Due to the special growth of chives, their cultivation methods and planting densities are different from those of shallots. Therefore, before planting, we should also pay attention to land selection, fertilization, and furrow planting.

Chives can be planted in the summer, be sure to choose the soil with good air permeability, if the stickiness is too large, it may lead to poor growth of chives. Be sure to water in time, and control the temperature well, because if the temperature is too high, it is easy to sleep.

The management rules for autumn planting green onions are to fertilize the soil when planting green onions to ensure the nutrients of the soil, and in the process of green onion growth, it is necessary to often sprinkle some farm fertilizer, and in the process of planting, it is necessary to prevent the occurrence of some insect pests, and to manage the planted green onions, and to pick the planted green onions in time, so that the green onions can grow better.

Watering: After the beginning of autumn, as the temperature drops, the growth rate of green onions accelerates, so it is necessary to water in time. After the white dew, the green onion enters the formation period of green onion, the water demand is large, watering every 6 7 days, each time the water must be watered thoroughly, and the ground should be kept between the two adjacent waters.

For easy storage, stop watering 1 week before harvesting.

Be sure to sterilize and disinfect the soil first, and then supplement the nutrients, in the process of planting green onions, we should pay attention to the planting technique, and water in time, the growth of green onions is very tenacious, and there is no need to pay too much attention to it, but we should also pay attention to the light, not too much water, which can easily lead to rot.

First of all, field management should be strengthened, and watering should be done frequently, ensuring that small amounts are repeated in small amounts. At the same time, it is also necessary to fertilize scientifically, and top dressing should be carried out after autumn. Timely control of pests and diseases, and cleaning of diseased plants. Agents should also be used in rotation to avoid resistance.

Water and fertilization should be done in a timely manner, and water and fertilizer management should be strengthened, and soil moisture and fertility should also be ensured, and pesticides should be sprayed regularly, pest removal should be done, and sufficient sunlight should be ensured.

It can be divided into green onions and shallots.

Green onions are planted by farmers in our place relatively few, except for vegetable farmers who grow vegetables and sell them, most people are planting shallots, shallots are divided into shallots and green onions, shallots are planted according to the season, such as the often said "July green onions, choose the type of green onions to be planted, find the seeds, choose a piece of good drainage that can get sunshine all day, dig to a depth of 30 cm, and add compost."

etc. or other organic substances.

For four-season cultivation, we should choose cold-tolerant, drought-tolerant, heat-resistant, adaptable, white and long, non-tillering varieties, such as Chinese giant onion and Zhangqiu green onion.

tall white) or local peasant varieties whip scallions. Onion varieties are not suitable for cultivation in four seasons. Digging and planting ditches:

Generally, the depth of ditching is the height of green onion white - the height of soil cultivation - 1 4 green onion white height. 1 4 The height of green onion white is the white part of the green onion above the soil to below the five prongs of the green onion leaves. Before ditching, it is necessary to first understand the general white height of the selected green onion varieties.

Sowing method The suitable density of green onion seedlings is 1.5 million plants per hectare, and the number of seedlings sown in autumn should not be less than 3 million plants, so as to prepare for freezing to death weak seedlings in winter and a small amount of seedlings. Spring sowing should have 2.25 million seedlings per hectare for interspersed seedlings and a small number of naturally dead seedlings.

Plant spacing 4 5 cm, 18000 22000 plants per mu. The white type of dwarf shallots is generally 50 70 cm with a plant spacing of 3 4 cm, with about 25,000 plants per mu. Select the type of green onion you want to plant.

Green onions or shallots are some green seedlings that appear before the shallots form. They are extremely immature green onions. Look for heart-shaped green onion seeds, such as shallots, or simply choose your preferred white, red, or yellow shallots to plant.

Green onions are an indispensable vegetable in today's life, especially in the north, where they are a common dish all year round. Green onions can be planted in all seasons, as long as the soil can be dug up. Even in the north in winter, if planted in late autumn, it will still germinate in the following spring.

The selection of varieties should be able to withstand cold and heat, have strong adaptability, and can be planted in all seasons.

The method of planting green onions is to dig a hole in the ground and then plant the green onions in the ground. The management method of green onion is to fertilize the land before planting, and then water it once every three days during the growth process of green onion, pay attention to whether there will be insect pests on green onion, and finally pay attention to the protection of green onion, these are the management methods of green onion.

First of all, when planting, we must choose the soil is more fertile and broad, and in the process of planting, we must choose farmhouse fertilizer, do not use the fertilizer bought outside, but also to prevent the occurrence of pests and diseases, but also to water the plant frequently, if there is a small insect situation, then we must spray in time to remove insects.

First of all, it is necessary to choose high-quality seeds, and we must pay attention to density when planting, and we must pay attention to ventilation and watering, and we must kill insects in time in the process of planting, and we must sterilize the land, and then we also need to fertilize and weed in time

The chive planting technology is planting time, land preparation and fertilization, seed treatment, sowing method, and management method is water and fertilizer management, pest control.

Cultivation techniques

1. Planting time

The most suitable season for planting chives in the open field is spring and autumn, the spring chives are sown from March to April each year, and the autumn sowing time is from September to October every year. Some areas have greenhouses for cultivation, so it is possible to grow them in both summer and winter.

2. Soil preparation and fertilization

Before planting, the land should be prepared first, and the weeding can be manually turned deeply, and there is no need to use herbicides to avoid drug residues affecting the growth of chives. If you want to grow well, the bottom fertilizer should be sufficient, and about 3,000 catties of farm fertilizer can be applied per mu, and no farm fertilizer can be replaced by chemical fertilizer. Chemical fertilizer is mainly ternary compound fertilizer, and the dosage is about 30 to 50 catties per mu.

3. Seed treatment

If you want chive seeds to germinate quickly, you can properly carry out germination treatment, germination is relatively simple, clean the seeds in clean water, remove some bad seeds, and then put the seeds into warm water about 50 degrees to brew, and stir continuously for about 15 minutes to achieve a disinfection effect.

Then soak the seeds in clean water, and then wrap the soaked seeds with a wet towel for germination, generally about 3 days will germinate one after another, when the germination rate reaches 70%, you can sow seeds.

4. Sowing method

Generally, ditching is used for sowing, the row spacing is about 15 cm, the seeds are evenly sprinkled in the furrow, covering about centimeters of soil, and the seeds are generally used to do about kilograms per acre. After the sowing is completed, the chives will sprout one after another in about a week.

Management methods

1. Water and fertilizer management

The root system of chives is relatively shallow, and it is sensitive to fertilizer and moisture, so growers need to fertilize and water it reasonably. Soil maintenance is dry and wet, pay attention to timely drainage in rainy days, watering in arid and rainy areas needs to be increased appropriately, watering time is best to choose in the evening, three to five days before harvest to stop watering.

2. Pest control

Chives have the fewest pests and diseases of all vegetable varieties during their growth. The common disease is the dry leaf tip, the main reason is that in addition to the dry soil, the rest is the lack of calcium and other deficiency diseases, which can also be said to be the disease caused by malnutrition, which can be prevented by adding some calcium fertilizer and phosphorus and potassium fertilizer, calcium fertilizer is commonly lime, which can be used together as a base fertilizer.

Planting chives is generally best carried out in spring and autumn, first of all, the land should be deeply turned and applied base fertilizer, after digging a ditch for furrowing, you can evenly sow chives seeds into the soil, keep the soil slightly moist, sowing about a month and a half after planting, daily management to apply thin fertilizer, but also need to pay attention to the prevention and control of pests and diseases.

1. Planting time

Planting chives needs to be carried out at a suitable time, it likes a cold and cool climate environment, and its optimal growth temperature is about 20, so according to the habits of chives, the most suitable planting time is in the spring and autumn of each year, otherwise the climate and environment are not suitable, and it is difficult for chives to grow vigorously.

2. Soil preparation and fertilization

Chives like to grow in loose and fertile, good drainage and easy drainage and irrigation in the heavy loam soil, when planting chives, you need to first turn the soil deeply, but also apply a sufficient amount of base fertilizer in the soil, so that the nutrients of the soil are more sufficient, and finally dig a ditch for furrowing, furrow width meters, height 15-20 cm.

3. Carry out planting

The seeds of chives are sown evenly into the soil using the strip sowing method or the method of sprinkling, keeping the soil slightly moist, and soon it can emerge seedlings, generally about a month and a half after sowing, you can plant it into the soil according to the method of every 8-10 plants a hole, row spacing of 12-20 cm, and hole spacing of 8-10 cm.

4. Maintenance management

Chives seedling stage and planting, the soil needs to keep the soil slightly moist, transplanting seedlings need to be regularly weeded for it, in order to promote the growth of its roots, in its growth period also need to apply thin fertilizer frequently, so that chives can grow vigorously, and pay attention to the prevention and control of pests and diseases in the breeding process.

Planting technique: Spring and autumn planting, suitable for growing in a cool environment, need to keep the ambient temperature at about 20, preferably in early March or early September; Land selection and land preparation, suitable for growing in well-drained and sunny soil, and then apply well-rotted farm fertilizer; Sow seeds into the soil, choose seeds with full grains and no disease, and water them in time after sowing. Management methods

Sufficient nutrients and water need to be provided during the planting process.

1. Spring and autumn planting

Chives prefer to be grown in a cool environment and are suitable for growing in temperatures around 20. It is best to plant in autumn or spring, when the climate is warmer and more suitable for later management. It can be planted in early March or early September, and in the northern regions, it is best to sow in the spring.

2. Land selection and land preparation

It is best to choose an environment with good drainage and sufficient sunlight to plant chives, and the debris on the soil should be removed before planting, and the soil should be turned after applying basal fertilizer. The use of rotten and mature farmhouse fertilizer as the base fertilizer chives will grow better, which is convenient for later management, and should be dug as a furrow.

3. Sow seeds into the soil

Seeds with full grains and no disease should be selected for sowing, and the seeds can be evenly sprinkled on the soil by spreading or strip sowing, and then covered with a thin layer of soil. After sowing, it needs to be watered in time, and the seedlings will emerge quickly in a warm and moist environment, and transplanting can begin after a month.

During the growth of chives, it is necessary to provide sufficient water and nutrients, but it is necessary to avoid overwatering and generating stagnant water. If the weather is drier, water the soil frequently and twice a week. If there is a lot of rain, it needs to be drained in time.

When the growth rate is fast, fertilizer should be applied frequently, and fertilizer should be applied once a week.
