What season to plant garlic and what season is the best time to plant garlic

Garlic is not resistant to high temperatures, has strong cold resistance, likes cold and cool environmental conditions, and is suitable for cultivation in the cool season.

The environmental conditions required for garlic cultivation.

1. Temperature: Garlic likes cold environmental conditions. It is adapted to temperature, the low limit is -5, the high limit is 26.

After the garlic has passed dormancy, it can germinate and take root at 3 to 5 hours. The suitable temperature for stem and leaf growth is 12 16. The suitable temperature for the development of flower stems and bulbs is 15 20, when it exceeds 26 or more, the plant physiological disorder, the stems and leaves gradually dry up, and the underground bulb will also stop growing, in the area where the average temperature is below -5 in winter, the garlic sown in autumn can not overwinter naturally.

Garlic plants were in the range of 0 5 low temperatures, and after 30 to 40 days, vernalization was completed.

2. Light: The vernalized garlic begins to differentiate flower buds and scale buds under the conditions of long sunlight and high temperature. In a short day and cold environment, it is only suitable for the growth of stems and leaves.

Scale bud formation will be inhibited. Therefore, whether it is spring sowing or autumn sowing, it must go through the conditions of low temperature and long sunshine.

3. Moisture: Garlic is a shallow root crop, which likes moisture and is afraid of drought. Before and after sowing, the soil temperature is required to be higher, so that it can germinate and root quickly, and the seedlings should reduce irrigation in the early stage, strengthen the cultivation and loosen the soil, promote the development of the root system, and prevent the seed petals from being wet and rotten.

The flower stem elongation period and the bulb expansion period are the vigorous stage of garlic growth and development, and it is also the stage that requires the most water, which requires the soil to be kept moist frequently, and the soil moisture is required to be reduced close to the maturity stage, so as not to cause rotten neck and scattered petals, garlic skin blackening, and reduce quality due to high humidity, high temperature and lack of oxygen.

4. Soil and nutrition: garlic does not have strict requirements for soil types, but it is best to use fertile loam, loose and breathable, good water retention and drainage performance, and the ecological environment is conducive to the growth and development of bulbs. The optimal pH value of soil pH is pH5, the end of the acid root becomes thicker, and the prolonged growth is stopped, and the seed petals are easy to rot if the alkali is too alkaline, and the small head and single clove garlic increase, reducing the yield.

When is garlic planted.

The sowing period of garlic varies depending on the region and variety, and can be divided into autumn and spring sowing. The north latitude of 35 38 is the dividing line between spring sowing and autumn sowing of garlic, and the winter in the south of 35 is not too cold, and the garlic seedlings can be naturally overwintered in the open field, mostly in autumn sowing, and harvested in early summer of the next year. In the area north of latitude 38, the winter is very cold, the seedlings can not safely overwinter, and the autumn sowing is prone to frost damage, so it is advisable to sow in early spring and harvest in mid or late summer.

The area between latitude 35 and 38 north can be sown in spring and autumn. Although the specific sowing date varies greatly from place to place, the average daily temperature at the time of spring sowing is generally between 3 6. The average daily temperature during autumn sowing is about 20 22.

The growth period of spring-sown garlic, especially the seedling growth period, is significantly shorter than that of autumn-sown garlic, so it should be sown as early as possible to meet the requirements of low temperature in the vernalization process, so that the garlic can be mossed and divided. If the spring sowing is too late, it will inevitably affect the formation of products and reduce the output. The suitable sowing date for autumn sown garlic in the open field in the north is from late September to early October.

Spring sowing is carried out in Northeast China, North China, Inner Mongolia and high-altitude areas, and after the local soil thaws, the average temperature is stable above 5.

When is garlic fertilized.

Generally, garlic grows rapidly after regaining vitality in early spring, at this time, it is necessary to pay close attention to fertilization, and it is advisable to apply all-element compound fertilizer, not nitrogen fertilizer or phosphorus and potassium fertilizer alone. Generally, the method of watering combined with watering is used to fertilize, and the temperature is relatively low at this time, and the phenomenon of burning garlic due to fertilizer transpiration will not occur. After beating the garlic moss, it is necessary to apply a fertilizer based on phosphorus and potassium fertilizer, and the fertilization method is the same as above.

Organic fertilizer can also be applied on top of these two fertilizations, so that the garlic produced is a green food. These two stages are the first time for garlic to grow, and it is absolutely critical to apply good fertilizer and sufficient fertilizer.

Autumn. The normal month is around mid-September.

Autumn is from late September to early October.

Spring 2-3 months.

Garlic prefers to grow in low temperatures and humid conditions, and is best cultivated when the temperature is 17 degrees Celsius, depending on the local climatic conditions.

Generally carried out in late September to early October in autumn, the climate, temperature and light in this season are very suitable for its growth, the warm areas in the south can be planted in advance to August, and can also be planted in spring 2 and 3 months, but the survival rate is not as high as autumn planting.

Garlic cultivation method

1. Seed selection

Garlic seeds for planting are generally selected to have large roots and size, garlic cloves are full and best, if it is a large area of planting limbs, it is necessary to choose ordinary garlic to ensure that the growth is uniform after the emergence of seedlings, pay attention to the selection of garlic seeds to dry for one to two days.

2. Planting

When planting garlic, you need to choose fertile, loose, well-drained soil, dig a 3-5 cm pit in the soil, plant the roots of the garlic cloves facing down, and keep the interval between the garlic cloves 15 cm, not too dense.

3. Maintenance

After mulching the soil, water generously until the pot is overflowing, then move the pot to the shade for 2 to 3 days before budding, taking care to avoid direct sunlight.

Autumn sowing. Autumn sowing is mainly suitable for the central and southern regions where the minimum temperature is lower than -12 in winter, and the suitable time for autumn sowing at different latitudes of different geographical inspection bureaus is also different, and it is generally delayed from south to north, and it is advisable for garlic seedlings to grow 4-5 leaves before wintering.

The growth period of autumn-sown garlic is long, the yield of garlic seedlings, garlic sprouts and garlic heads is high, and it is the main cultivation form of high-quality garlic, but if the autumn-sown garlic is sown too early, the growth will be greater before the wintering stops growing, and the cold resistance of garlic seedlings with large growth is low, and if the sowing is too late, the growth amount will be smaller before wintering, and the cold tolerance of seedlings will also be reduced.

In the geographical latitude is higher, which mill is colder in winter, in the selection of autumn garlic to choose the garlic species of white skin garlic, the cold resistance of the white garlic is better, the safety factor of wintering is also higher, and when choosing garlic species, the choice of a single clove weight of 4-6g garlic species is a slow and slow way.

Spring sowing. Spring-sown garlic is suitable for areas with the lowest temperature below -12 in winter, and the specific sowing time of spring-sown multi-clove garlic production is suitable for the "top period" when the soil surface thaws during the day and still freezes at night, and the production of single-headed garlic should be appropriately delayed. The sowing time is late and the temperature is high, and the garlic can not complete the low temperature requirements required for the differentiation of scale buds and flower buds, and it is easy to form single-headed garlic or split garlic, and the growth period of garlic will become shorter, which will affect the yield of garlic.

Garlic will dry up and stop growing when the temperature is higher than 26 degrees Celsius, so it is important to extend the growth period of garlic to improve the yield of garlic, while the late spring sowing time is low because of the short growth period. However, in the process of garlic cultivation, this characteristic of garlic is often used for the cultivation of single-headed garlic (that is, "planting garlic does not grow out of nine and nine grows single-headed" in the agricultural proverb), specifically when the temperature is stable at 4 (when higher than 4, garlic is difficult to complete the differentiation of scale buds and flower buds). The yield of single-headed garlic is low, but the price is higher, generally about 3 times that of multi-clove garlic**.

Garlic is suitable for planting in several months.

Garlic prefers to grow in a low temperature and humid environment. The temperature is around 17 degrees Celsius, which is the best time for planting. Its cultivation depends on the local climatic conditions.

It is generally held from late September to early October in autumn. This season, the climate, temperature and light in the United States are very suitable for its growth. In the warm areas of the south, it can be planted in August or spring from February to March, but the survival rate is not as high as that of autumn planting.

Garlic cultivation method

1. Seed selectionGenerally, garlic seeds should be planted with large roots and large heads, and the full garlic cloves are the best. If planted in a large area, garlic with ordinary head should be selected to ensure uniform growth after emergence. Pay attention to the selected garlic seeds to dry for a day or two.

2. PlantingWhen growing garlic, you need to choose fertile, loose, well-drained soil. Dig a 3-5 cm hole in the soil and plant garlic cloves with the roots facing down. The spacing of garlic cloves should be kept at 15cm, and it must not be too dense.

3. MaintenanceAfter mulching, water generously until the water in the pot overflows, then move the pot to a cool place where it will germinate in 2 to 3 days. Be careful to avoid direct sunlight.

Points to note when planting garlic.

1.Garlic needs a lot of water to grow. Because its root system has a weak ability to absorb water, it is necessary to keep the soil moist at the seedling stage and water it once a day in the morning and evening.

2.When the garlic grows to 10 cm after germination, pull out the slow-growing sprouts to keep the garlic nutrient.

1. Garlic can be planted all year round, but it is best to plant it in autumn or winter.

2. Garlic likes cold environmental conditions, and the suitable temperature for its growth is 12 25. The minimum temperature of garlic clove germination is 3 5, the germination above 12 is rapidly accelerated, and the optimal temperature for germination is about 20. The appropriate temperature for the growth of seedlings is 14 20, when the seedlings have 4 5 leaves, they can withstand low temperatures above 16, the suitable temperature of garlic moss extension period is 15 20, and the suitable temperature of bulb expansion period is 20 25, if the temperature is too high, the bulb stops growing and turns into a dormant state.

Garlic is also a green vernal type. Generally, garlic germinates to the seedling stage, and if it encounters 0 4 or low temperature, it passes the vernalization stage after 30 to 40 days.

3. Garlic is a long-day plant, and under more than 12 hours of sunshine and a temperature of 15 20, the top bud on the stem plate will turn to flower bud differentiation and rapid mossing. The development of garlic moss is not only affected by temperature and light, but also related to nutritional conditions. If the seed petals are too small, the soil is barren, the sowing is too late, the density is too large, the fertilizer and water are insufficient, etc., it is possible to form moss-free garlic or one-headed garlic.

In addition, the formation of garlic heads requires long days. In general, under short daylight, varieties only differentiate new leaves and cannot form bulbs. However, there are also early-maturing varieties that are less stringent in their photoperiod requirements.

4. Garlic leaves belong to the drought-tolerant ecotype, but the root system of Sousen is shallow in the soil and the ability to absorb water is weak, so in the early stage of vegetative growth, the soil should be kept moist to prevent the soil from being too dry. Especially during the elongation of flower stems and bulb swelling, the soil should be kept moist to prevent it from drying out. Especially during the elongation of flower stems and bulb expansion, more water is required, and the soil is required to be kept moist at all times.

In the late stage of bulb development, watering should be controlled and soil moisture should be reduced to promote the maturity of the bulb and improve the storage tolerance, so as to avoid the rotten neck (base of the pseudostem) caused by high humidity, high temperature and lack of oxygen, and the garlic skin will turn black, thereby reducing the quality.

For the sowing time of garlic, the Yangtze River basin and its southern areas are generally sown in mid to late September.

Garlic is like cold and cool climatic conditions, the suitable temperature for the growth of stems and leaves on the ground is 12-16, the best seedling age for seedlings to overwinter is 4-6 leaf stage, it takes 40-50 days from sowing to grow into 4-6 leaves, if the average daily temperature is below 7, it will stop growing.

The weather is cool at this time of September, which is suitable for garlic seedlings to emerge and grow. Garlic planting time is very important, if you sow too early, garlic seedlings will grow too vigorously before wintering, which will deplete health and reduce overwintering ability.

Therefore, sowing or celery in the Yangtze River basin around mid-September can make the plant grow to 5 or 6 leaves before wintering, and the plant at this time has the strongest cold resistance, so it will not be frozen to death in the severe winter, and can lay a good foundation for the plant to successfully pass vernalization.

If the garlic is sown too late, the root system will be weak, the seedlings will be small, and the cold resistance will be low, so that the death of many jujube gods during the overwintering period will be great. Therefore, the sowing period of garlic must be strictly controlled.

Garlic

Garlic is the underground bulb of the lily family, Allium family. The whole plant of garlic has a strong spicy garlic smell, garlic head, garlic leaves (green garlic or garlic seedlings) and flower sprouts (garlic sprouts) can be eaten as vegetables, not only can be used as seasonings, but also can be used as medicine, is a famous edible and medicinal dual-purpose plant.

Autumn garlic is generally sown from mid to late September to early October, and spring garlic is suitable for sowing in March, after the soil thaws.

1. Sow garlic in autumn.

The growth cycle of autumn-sown garlic is long, and the requirements for sowing judgment period are strict. Some start sowing in early September, garlic sowing too early, seedlings grow too vigorously, too much nutrients are consumed before winter, yellow leaves are easy to appear, and the cold resistance is reduced, which is not conducive to safe winter. If sowing is too late, garlic seedlings emerge slowly, the root system is weak, the seedlings are small, and when low temperature frost comes, it is easy to suffer frost damage.

The suitable sowing time for autumn garlic is in mid-to-late September and early October, and mulching can be postponed by 5 to 7 days. Planting in this range, on the one hand, the temperature is 15 20, which is conducive to the germination of garlic cloves, and the garlic seedlings sown at this period are fast and complete. On the other hand, it can grow 5 or 7 leaves before winter, which is resistant to cold and is conducive to later management.

2. Spring sow garlic.

As the saying goes, spring garlic does not come out of nine, but out of nine long single heads. In other words, the spring cong chong friends sow garlic can not be sown after nine days. Garlic is planted in the spring, and in general, it should be sown as soon as possible after the soil thaws to ensure that the garlic has enough time to grow.

But sowing is too early, the soil freezes, does not germinate. Sowing is late, the growth period is relatively short, it is easy to form one-headed garlic, and the yield is low. Generally, spring garlic is planted, and according to the local temperature, after the soil thaws, it can be sown.

It is not good to sow garlic too early or too late, and the appropriate sowing time should be selected according to the local climate change.
