Garlic is bright yellow, rich in flavor, fresh and delicious, rich in nutrition, the entire production process does not use chemical fertilizers and pesticides, is an authentic pollution-free agricultural products, favored by the majority of consumers. Next, introduce the main technical points for the production of Garlic Garlic using the soil warming pit during the autumn and winter slack season.
I. Variety selection
Choose Cangshan white garlic, this is an excellent local variety, garlic head hypertrophy, about 7 cm in diameter, skin white, usually 7 to 10 petals per head, single head weight about 45 grams, garlic hypertrophy, skin with a little purple Red, fast-growing, golden leaf tip, good quality and high yield, is an ideal variety for planting garlic yellow.
Second, the construction of soil warming pit
Garlic yellow has a short growing period and a wide range of temperature adaptability. It can grow at 12°C～30°C. With winter and spring farming season, the production site should choose the leeward sunny, high-desert land, and at the same time, when the outside temperature rises, it can cool well. The use of warm cellar to produce pollution-free garlic yellow is an ideal cultivation method, with advantages of small investment, simple cellar construction, and easy production and operation. Digging warm cellar, the general height of 2 ~ 2.5 meters, into the soil depth of 1 meter, exposing the ground height of 1 meter, cell length 7 meters, width 7 meters (cultivation area control in about 50 square meters), with a wooden frame or The bamboo poles are well-supported (it must be firmly fixed and the soil must be covered), and then the coverings such as corn stalks, rice straw, wheat straw, or ragweed should be laid. The top layer should be covered with clay, with a thickness of about 40 cm, at each of the four corners. Leave a ventilation window. Dig the entrance, the width of 40 to 50 cm, both sides with a good barrier. The cultivated bed soil is preferably made of organic-rich loam. 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 soil should be about 6 cm.
Third, put the garlic
Garlic bulbs have a certain period of dormancy. In order to break the dormancy and promote germination, they 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 with fresh water before sowing is also a day and night, so that the full absorption of garlic, accelerate germination. In order to increase the yield per unit area, the method of close planting should be used as far as possible when planting. When planting, the garlic should be planted closely in a planting pot, one by one. Immediately after sowing, cover 3-4 cm thick clay, pour water once, and cover the shade.
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 proper watering, controlling soil moisture and promoting the rapid growth of leaves. The dry leaves of the soil grow slowly, affecting product quality and yield. However, under confined conditions, such as air and soil moisture, it is prone to rot. Therefore, as much as possible to reduce watering, usually after planting watered once per minute, maintain a high humidity, to ensure the rapid emergence of garlic seed. Later, according to the outside temperature, soil moisture, garlic yellow growth conditions, flexible watering, 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 was poured to ensure that the yield and quality of garlic yellow, but also to lay the foundation for continued growth after harvest. After the “winterâ€, the outside temperature is significantly reduced, and the stove is to be raised in the cultivating pit to increase the temperature so that it can maintain normal growth. When the daytime temperature exceeds 20°C, the temperature should be lowered to 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. The garlic garlic harvested is tied into bundles and basks in the sun, turning the garlic leaves from white to golden. In the production process, the sowing date should be determined flexibly according to the harvest period so as to maximize the economic benefits.
