Which village is kind of garlic in Yuncheng?

There are many villages in Yuncheng, Shanxi Province that grow garlic, which belongs to the species distribution area, such as Shangguan Village.

Introduction to Shangguan Village:

Shangguan Village, Cecun Town, Qinxian County, Changzhi City, Shanxi Province is under the management of Cecun Town, close to Daoxing Village and Hezhi Village, with rich products and pleasant climate.

Main agricultural products: pepper, garlic, raisins, oranges, mushrooms, limes, lemons and zucchini.

Village resources: sandy soil and azurite.

Cultivation techniques of garlic:

Start sowing at the right time

The best time to sow garlic is to make the plant grow to 5-6 leaves before overwintering. At this time, plants have the strongest cold resistance and will not freeze to death in cold winter, which lays a good foundation for the smooth vernalization of plants.

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 the seeds are sown too early, the seedlings will grow too vigorously before overwintering, consume nutrients and reduce their overwintering ability, which may lead to vernalization again, resulting in 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 low, and more people will die during the winter. Therefore, the sowing date of garlic must be strictly controlled.

rational close planting

Close planting is the basis of increasing production. The yield of garlic bolt and garlic consists of the number of plants per mu, the number of garlic cloves per plant, the weight of garlic bolt and the weight of garlic cloves.

Proper close planting should be carried out 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. It is best to plant about 50 thousand plants per mu. Row spacing14 ~17cm, plant spacing of 7 ~ 8cm, seeds per mu150 ~ 200kg.

Mid-late maturity varieties have long growth period, tall plants, many leaves and low density, which makes the population structure reasonable and makes full use of light energy.

The density should be about 40,000 plants per mu, the row spacing16 ~18cm, the plant spacing10cm, and the yield of seeds per mu150kg.

Sowing method

The suitable sowing depth of garlic is generally 3 ~ 4 cm.

There are two ways to sow garlic: one is planting, that is, inserting seed petals into the soil and covering the soil after sowing, which is practical; The second is ditching and sowing, that is, digging a shallow ditch with a hoe and sowing seed petals in the soil.

After a ditch is opened, the soil at the same time covers the petals of the previous row of seeds. After sowing, the soil cover is about 2 cm thick, which is slightly practical and permeable with feet.

To prevent drought, cover the soil with two layers of straw or other moisturizing materials.

Planting should not be too deep, which will lead to late emergence, too long pseudostems, too much water-absorbing fertilizer in the roots and too fast growth, and it is difficult for garlic to expand when squeezed by soil.

However, the planting should not be too shallow. If it is too shallow, it is easy to "jump" when seedlings emerge, the rhizosphere is easy to lack water at seedling stage, the root system is underdeveloped, and it is easy to freeze to death in winter.

Tiantuan management

Topdressing Although garlic seedlings have petal nutrition during the growth period, topdressing should be done in time in order to promote seedling growth and increase the nutritional area of plants.

Because the root system of garlic is weak in absorbing water and fertilizer, quick-acting fertilizer should be applied to prevent the tip of garlic from yellowing.

Garlic topdressing is usually 3 ~ 4 times, which is divided into: seedling-promoting fertilizer: after garlic is fully grown, apply human manure 1 time to raise seedlings, avoid ammonium bicarbonate and prevent seedlings from burning. ?

Filling fertilizer: after 60-80 days of sowing, apply decomposed human and animal fertilizer and chemical fertilizer 1 times, 20-30 loads per mu, ammonium sulfate 10 kg, and 5 kg of potassium sulfate or potassium chloride. Early-maturing varieties should be driven early, and late-maturing varieties should be driven late to promote the vigorous growth of seedlings, strong stems and leaves, and few or no yellow shoots.

Fertility: After planting garlic, flower buds and scale buds gradually differentiate into flower stem elongation period. During this period, the old roots are aging and a large number of new roots appear. At the same time, the stems, leaves and garlic bolts are also rapidly elongated, and garlic begins to expand slowly, requiring more nutrition. It is necessary to re-apply available potassium and nitrogen fertilizer (compound fertilizer is better) 10 ~ 15 kg. Apply it about half a month before the end (you can peel the seedlings and observe the short stems under the false stems) to meet the needs and promote the rapid and vigorous growth of garlic bolts.

Garlic swelling fertilizer: early-maturing and early-middle-maturing varieties, because the temperature is not high when garlic is swollen; Garlic swelling period is relatively long, in order to promote garlic hypertrophy, it is necessary to topdressing available nitrogen and potassium fertilizer before garlic bolting.

water management

Full seedling stage: Generally, after sowing 1 week, the whole seedling will be complete. After topdressing the whole seedling fertilizer, if the soil is dry, it can be irrigated 1 time to promote seedling growth.

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 emergence, because it is irrigated 1 time after emergence, and this period is also a 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.

Mid-late stage of seedlings: marked by the end of maternal withdrawal before overwintering. This stage is relatively long, and it is also an important period for the vegetative growth of garlic. In many places, the rainfall has been significantly reduced before wintering. When the soil is dry, water it 1 time; After overwintering, the temperature gradually rose and the seedlings began to grow vigorously again. Therefore, it is necessary to irrigate in time to promote the growth of garlic leaves and thicken the false stems.

Bolting stage: the differentiated leaves of garlic seedlings have all been exposed, the 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 period is the period when the amount of fertilizer and water is the largest, so water and bolting should be done in time after fertilization. After the "tail show", it is necessary to continue watering to promote seedlings, and stop watering for 2 ~ 3 days before harvesting to facilitate storage and transportation.

Garlic expansion period: water the garlic shoots immediately after harvest to promote the rapid expansion and weight gain of garlic. Before harvesting garlic. Stop watering for 5 days, control growth, and accelerate the transportation of assimilated substances from leaves to garlic.
