/kloc-after October 20th, garlic can be planted in the south, but it is not suitable for planting in the north, because the winter in the south is not cold, and the seedlings can safely winter, while the winter in the north is cold, which is easy to cause freezing injury. First of all, garlic should be sown in time. In the Yangtze River basin and its south area, it is usually sown in the middle and late September. Then reasonable close planting, with about 50,000 plants per mu as the best, the row spacing is14-17cm, and the plant spacing is 7-8cm, and reasonable water and fertilizer management is needed.

1. Can I still go to kind of garlic after1October 20th?

/kloc-after October 20th, garlic can be planted in the south, but it is not suitable for planting in the north. The peak season of garlic is around the cold dew, especially in the south, because the winter in the south is not cold, so the seedlings can also winter safely. Most garlic is planted in autumn and harvested in the next year, but it is cold in winter in the north, so it is not suitable for planting garlic in autumn, otherwise it is prone to freezing injury.

Second, the planting method of garlic

1, timely sowing

Sowing is usually carried out in the middle and late September in the Yangtze River basin and its south area. The weather in the Yangtze River basin is cool in September, which is suitable for the emergence and growth of garlic seedlings. If sowing is too early and the seedlings grow too vigorously before overwintering and consume nutrients, the overwintering ability will be reduced, and vernalization may be carried out again, causing secondary growth, and compound garlic will be formed in the next year, which will reduce the quality of garlic. If sowing is too late, the seedlings will be small, the tissues will be tender, the roots will be weak, the accumulated nutrients will be less, the cold resistance will be lower, and more people will die during the winter. Therefore, garlic must strictly control the sowing date.

2. Reasonable close planting

Close planting is the basis of increasing production. The yield of garlic bolt and garlic is composed of the number of plants per mu, the number of garlic cloves per plant, the weight of bolt and the weight of cloves. Proper close planting should be done according to the characteristics of varieties, so that there are more plants per mu. Early-maturing varieties generally have shorter plants, fewer leaves, shorter growth period and higher density, and it is better to plant about 50,000 plants per mu, with row spacing of14-17cm, plant spacing of 7-8cm, and seeds per mu of150-200kg. The middle and late maturity varieties have long growth period, tall plants, more leaves and lower density, so as to make the population structure reasonable and make full use of light energy. The density should be about 40,000 plants per mu, the row spacing16-18cm, the plant spacing10cm, and the seeds per mu150kg.

3. Topdressing

(1) Seedling-promoting fertilizer: After the garlic seedlings are fully grown, apply 1 time to raise the seedlings, and avoid applying ammonium bicarbonate to prevent the seedlings from burning.

(2) Growing fertilizer: after sowing for 60-80 days, re-apply 1 time decomposed human and animal fertilizer and chemical fertilizer, with 20-30 loads per mu, ammonium sulfate 10 kg and 5 kg of potassium sulfate or potassium chloride. Early-maturing varieties should catch up early, and late-maturing varieties should catch up late, so as to promote the vigorous growth of seedlings, strong stems and leaves, and less or no yellow tips when rotten mothers.

(3) Fertility: After planting garlic, flower buds and scale buds gradually differentiate into flower stem elongation period. In this period, the old roots are aging, and a large number of new roots occur. At the same time, the stems, leaves and garlic bolts are also rapidly elongated, and the garlic begins to swell slowly, so more nutrients are needed. Therefore, available potassium and nitrogen fertilizer (compound fertilizer is better) 10- 15 kg should be re-applied. Apply it about half a month before the end (you can peel off the seedlings and observe the short stems below the false stems) to meet the needs and promote the rapid and vigorous growth of garlic bolts.

(4) Garlic swelling fertilizer: early-maturing and early-middle-maturing varieties, because the temperature is not high when garlic is swollen; The swelling period of garlic is relatively long, so in order to promote garlic hypertrophy, it is necessary to topdressing available nitrogen and potassium fertilizers before garlic bolting is harvested. For example, 5- 10 kg of compound nitrogen and potassium fertilizer is applied per mu. If only urea is applied, it will be about 5 kg, and too much topdressing is not allowed, otherwise the formed garlic buds will turn green and grow leaves again, which will consume the nutrients of garlic cloves. Topdressing should be carried out before the young garlic shoots are harvested, and when the young garlic shoots are harvested, there are abundant nutrients to promote the garlic bulbs to swell. If topdressing is carried out after the young garlic shoots are harvested, it will easily lead to green greed and yield reduction. If the soil is fat and the garlic leaves are fat and dark, you can not apply swelling fertilizer. Because of the late bolting and high temperature, the middle and late maturing varieties usually harvest garlic in about 20-25 days after bolting, so they can also avoid chasing after swelling.

Step 4 water it

(1) Full-time seedling stage: seedlings will be full-time in one week after general sowing. After topdressing full-seedling fertilizer, if the soil is dry, it can be irrigated 1 time to promote seedling growth.

(2) Pre-seedling stage: The seedling stage is the key period for the differentiation and formation of garlic vegetative organs. Garlic enters the early stage of seedling growth after full seedling, because irrigation is 1 time after full seedling, and this period is also in the period of more autumn rain in the Yangtze River basin, so it is necessary to control irrigation and pay attention to field drainage after autumn rain.

(3) Mid-late stage of seedlings: marked by the period from before overwintering to the end of maternal withdrawal. This stage is long, and it is also an important period for the vegetative growth of garlic. Rainfall has been significantly reduced in many places before wintering. The soil is dry and should be watered 1 time; After wintering, the temperature gradually rises, and the seedlings begin to grow vigorously again. Therefore, irrigation should be done in time to promote the growth of garlic leaves and thicken the false stems.

(4) Bolting stage: All the differentiated leaves of garlic seedlings have been exhibited, the growth of leaf area has reached the peak, the root system has also expanded to the maximum extent, and the growth of garlic bolts has accelerated. This stage is the period with the largest amount of fertilizer and water, so bolting water should be watered in time after the fertilization. ? Now tail? After that, water should be continuously used to promote seedlings, and water should not be stopped until 2 to 3 days before harvesting to facilitate storage and transportation.

(5) Bulging stage of garlic: water the garlic bolt immediately after harvesting to promote the rapid expansion and weight gain of garlic. Before harvesting garlic. Stop watering for 5 days, control the growth, and accelerate the transport of assimilated substances from leaves to garlic.
