Garlic Variety-- Jiaxiang Red garlic

Jiaxiang red garlic is a local variety in Jiaxiang County, Shandong Province. It has been cultivated for 1900 years and enjoys a high reputation for its good quality and long dormant period. 1. The plant height of Jiaxiang red garlic does not exceed 50cm, and the leaves of the whole plant are 13, flat and narrow, with wax powder. Each garlic has 4-6 cloves, belonging to a few petal type, the skin is red, the meat is tender, the garlic juice is thick, the spice is thick, and the color and taste are all good. Jiaxiang garlic cloves are enlarged, have a long dormant period and are resistant to storage. they generally produce 800-1000kg and 200kg per 667m2. Second, the main points of cultivation techniques: 1, apply sufficient base fertilizer and prepare the soil finely. Choose loam and sandy loam with loose soil, convenient drainage and irrigation, water and fertilizer conservation, rich organic matter and sandy loam. The first crop should not be onion, garlic, onion and other crops. Ploughing and sun-drying should be done as soon as possible after the previous crop harvest, and one-time sufficient base fertilizer should be applied to the cultivated land. 667m2 should be applied with rotten stable fertilizer 5000kg, diammonium phosphate 50kg, potassium sulfate 50kg, iron fertilizer 3kg, zinc fertilizer 2kg, boron fertilizer 1kg, ploughing and raking fine, so that the ground is level, the upper and lower soil is loose, and then a 1.4m wide border is made to be sown. 2. Sowing at the right time and reasonable close planting. The suitable sowing time of autumn sowing garlic is that the soil temperature of 5cm is between 18-20 ℃, and the suitable sowing time in Jiaxiang County is around the National Day. The seedlings emerge in 7-9 days. Before overwintering, the plant can grow 5-6 leaves, plant height 25cm and root about 30. Before sowing, choose garlic cloves with fat, white color, root protuberance at the base and disease-free cloves to be sown. The results showed that it was suitable to sow 8 rows per row, row spacing 15-20cm, plant spacing 10cm, 35000 plants per 667m2, and seed 160-180kg. Immediately pour enough water after sowing, spray Acetochlor once (every 100g 50kg to water) when the topsoil is dry and wet, and cover the film after spraying. 3. Strengthen management and cultivate strong seedlings. Immediately after sowing, garlic should be watered thoroughly for the first time to promote bud germination. Water was watered for the second time after emergence to facilitate the growth of seedlings. The Spring Equinox watered thoroughly before and after returning green water, and applied diammonium phosphate 20kg per 667m2 combined with watering to meet the nutritional requirements of garlic during the withdrawal period. The elongation stage of garlic bolting is the stage of both vegetative growth and reproductive growth. The bolting of seedlings should be promoted by big water and fertilizer, and the ternary compound fertilizer 15-20kg should be applied per 667m2. After bolting, top-promoting fertilizer was applied, and 15-20kg compound fertilizer per 667m2 was applied. Immediately after application, the leaves and roots were watered to prolong the life span of leaves and roots. After that, the soil was watered as soon as it was dry, until it stopped watering one week before harvest. 4. give priority to prevention, timely control of diseases and insect pests. The diseases of garlic, such as leaf blight, gray mold, virus disease and purple spot disease, can be effectively controlled by strengthening the management of garlic field, increasing the application of organic fertilizer, applying fertilizer scientifically, enhancing plant resistance, preventing stagnant water in the field, cultivating virus-free seedlings, timely removal of diseased plants and other agricultural measures. After the onset of the disease, leaf blight and Botrytis cinerea were controlled with 50% methyl topiramate 500 times or 65% Dysen zinc 500 times. Dry rot is sprayed with 1000 times of 50% methyl topiramate or 75% chlorothalonil. Purple spot disease is controlled by Kelu and Ruidushi, but it is easy to produce resistance when used alone, so it should be used alternately with other agents. The insect pests are mainly onion flies, which can be trapped and killed by sugar and vinegar solution (sugar: vinegar: water = 1 / 2 / 2, and a small amount of trichlorfon), spray with 600x solution to prevent adults from spawning, or root irrigation with 50% dichlorvos EC or 40% dimethoate EC. Thrips are sprayed with 40% dimethoate EC 800 times. 5. Harvest ⑴ garlic bolts. When the hook of garlic bolting is in the shape of a big scale hook, the bud becomes larger obviously, and the color is from green to yellow-green, it can be harvested. The harvest of ⑵ garlic. When most of the garlic leaves are dry, the upper leaves fade to the leaf tip dry and droop, and the plant is soft, harvest and dry in time.
