High-yielding Cultivation Technique of Purple Peel Garlic

First, sowing time: timely sowing of garlic, early life and quick hair, garlic moss bolting early, high efficiency. However, when it is broadcast in time, the incidence of garlic leaf blight is high and the plants are susceptible to premature aging. Suitable sowing time is generally from late August to late September. Warm and cool areas can be broadcast properly and warm areas can be postponed. Second, the density: to harvest garlic and garlic, the general cultivation density of 5-6 million / acre, acres per acreage of 120 kg. Sowing advocated on-demand. According to the test results, proper depth broadcast can increase the rate of garlic, so the depth of cover soil after sowing should be controlled at 4-8cm. Rice-planted garlic and relatively heavy soil cover soil should be shallow. Third, fertilizer and water management: Garlic root distribution is shallow, drought-resistant, and not tolerant, should be based on soil moisture and plant growth conditions, timely irrigation. Garlic grows for a long period of time and requires a large amount of fertilizer. Generally, the quality of Mushi is 3000-4000 kilograms, especially for plots, and organic fertilizers must be added. The application of inorganic fertilizer, n, p, k ratio is: urea 40-60 kg, general through the calcium phosphate 30-50 kg, 15-30 kg of potassium sulfate. The manure and calcium were used as the base fertilizer once, and the urea and potassium sulphate were separated from the mother (4-6 leaves) and the Pengda period (9-10 leaves) twice. The fertilization amount in the mother-rejection accounted for 60%, and Pengda period accounted for 40. %. Fourth, pest and weed control. The main diseases of garlic are leaf blight, purple spot, rust, white rot, and sclerotia. Prevention and control should be based on agricultural control, supplemented by chemical control. The key to chemical control is the early stage of disease (after the 5-leaf stage), with the focus on the peak period of the disease. The chemical control agent was selected to use 1500 times of the 10% Shigao powder, or 25% Shi Baoke EC 1000 times, or 25% KOWEI EC 1000 times. 7-10 days prevention and control, continuous prevention and control 3-4 times, control effectiveness of more than 90%. The main insect pests are Liriomyza sativae and Onion beet scale moth, Thrips, Aphids, etc. Can be sprayed in the garlic 3-4 leaf stage 1.8% harmful to the extreme destruction of EC 10-15 ml / mu, or 1.8% afore EC, or pyrethroid pesticide control, can effectively control the pest of garlic hazards. Grass damage can be treated by 20-25 days after sowing, 3-4 leaf stage of garlic seedlings, and 2-3 leaf stage of madder grass species, with a net of 40% Garlicgrass 110ml or 20% greengrass per acre. Long 300 g/mu watered spray. The one-time weeding effect reached more than 90%, which is safe and effective for garlic production. V. Timely harvesting: The harvest of garlic moss: When the leaves of the inflorescence of the curd inflorescence leaves 13-16cm from the leaf sheath, the garlic can be harvested. When harvesting, select sunny afternoon or cloudy dew and dry. Closing garlic: Garlic generally requires "nine yellow and ten closed," too early to close, garlic tender, heavy water, garlic wrinkled after drying, too late, garlic peel color is easy to crack, poor commercial quality, product quality is reduced. Exclusive garlic and divided garlic should be harvested in batches. In the 20-30 days after the harvest of garlic, the leaves can be harvested when the leaves are yellow, and when they are harvested, their mud, cutting roots and cutting handles should be avoided to avoid mechanical damage. When garlic is used for continuous cropping, it is advisable to promote crop rotations and make a full rotation in 2-3 years. Generally non-garlic crops can be rotated with garlic, such as wheat.
