Key Techniques for Production of Garlic Garlic in Warm Earth Pits in Autumn and Winter

Garlic yellow is well-received by consumers because it is rich in flavor, fresh and delicious, and nutritious. Now it is time to plant autumn and winter garlic yellow season, the following describes the relevant technical points for the reference of growers.

First, choose the best species. In the production should choose the higher yield varieties, such as Cangshan white garlic, this species of garlic head hypertrophy, transverse diameter of about 7 cm, skin white, generally 7 to 10 petals per head, single head weight of about 45 grams, garlic hypertrophy, The skin is slightly purple. Fast germination, golden tip, good quality, high yield.

Second, build a warm cellar. Garlic yellow has a short growing period and a wide range of temperature adaptability. It can grow at 12°C~30°C. In autumn and winter, during the slack season, the production sites should choose the leeward, sunny, high-desert plots, in order to help improve the temperature of the warming pits, reduce frost damage, and at the same time when the outside temperature rises, it can cool down well. Low temperature outside the winter, the use of warm pits production garlic yellow with a small investment, cellar construction is simple, easy production and operation advantages. Digging warm cellar, the general height of 2 to 2.5 meters, into the soil depth of 1 meter, revealing the ground height of 1 to 1.5 meters, cell length of 7 meters, cellar width of 7 meters (cultivation area control in about 50 square meters), used in the above Wooden or bamboo poles are well supported, and then corn, straw, wheat straw, or haystacks are covered. The top layer is covered with clay and has a thickness of about 40 cm. There is an air release window at each of the four corners. Dig channel entrance, the width of 40 to 50 cm, both sides with a good barrier. The cultivation bed soil is preferably made of loam soil rich in organic matter. The thickness of the soil layer is 10 to 12 cm. The surface of the cultivation pond should be flat, and the sand or sandy loam should be about 6 cm thick.

Third, the kind of cloth bed. Garlic has a certain period of dormancy. In order to break the dormancy and promote germination, it must be treated before sowing. The method is to remove the bulb skin, the base stem plate, and some or all of the garlic peels, so as to facilitate moisture absorption and gas exchange. Before sowing, low-temperature treatment at 0°C-4°C should be performed. After the low-temperature treatment, garlic can be emerged in advance. In addition, soaking in fresh water before sowing, so that the kind of garlic fully absorb water and accelerate germination. In order to increase the yield per unit area, the method of close planting should be used as far as possible when sowing. When garlic is placed, the garlic is planted in a closely spaced plant in a cultivated pot, leaving no gaps between the cloves. Generally about 20 kg of garlic per square meter. Immediately after sowing, cover 3-4 cm thick clay, pour water once, and cover the shade. The gauze is laid at a distance of 20 cm from the surface of the cultivated bed. The gauze is leveled around the corner and fixed with an iron bar or bamboo raft.

Fourth, face management. Garlic yellow mainly uses the nutrients stored in garlic bulbs to transform into fresh leaves for food. The key to management is timely and appropriate watering, controlling soil moisture and promoting rapid leaf growth. Dry soil and slow leaf growth affect product quality and yield. However, under confined conditions, such as air and soil moisture, it is often prone to decay. Therefore, as much as possible to reduce watering, usually after pouring a water per plant, maintain a high humidity, to ensure the rapid emergence of garlic seed. Later, according to the outside temperature, soil moisture, the growth of garlic yellow flexible water, can not make the humidity in the warm cellar too high. In the early stage of growth, the amount of water sprayed is small, and it gradually increases in the later period. Before the harvest, a small amount of water is poured once again to ensure that the yield and quality of garlic yellow, but also to lay the foundation for continued growth after harvest. After entering the winter season, the outside temperature is significantly reduced. To increase the temperature, heat the stove in the cultivation pits. When the daytime temperature exceeds 20°C, let the air cool and prevent the high temperatures from becoming long.

Fifth, timely harvest. Garlic can be harvested when it reaches a height of 35 to 45 cm. In general, garlic yellow takes 25 days from planting to cutting knife, and the second knife can be collected in about 20 days. Harvest it when it is harvested. Do not root it up. Harvest garlic yellow is generally good in the afternoon, garlic garlic harvested tied into bundles, drying in the sun, you can make garlic leaves from white to golden yellow, improve its appearance. In the production process, the sowing date should be determined flexibly according to the harvest period so as to maximize the benefits.
