First, selection of good varieties of garlic should choose early maturity, high yield, disease resistance Huanong 1, Huanong 2 and so on. Selected garlic dry 2 to 3 days, and then soaked in 25% carbendazim 250-fold dilution of 10 to 12 hours, remove and broadcast after drying. Leeks are selected from the group of leafy leeks, ie, leafy leeks, which have not only leafy leaves with large leaves, but also lack of engraved leaves, strong cold resistance, and high quality and taste.
Second, the appropriate period of fine sowing The Yangtze River Valley is usually sown in early September to early October. Before sowing, it is advisable to choose high-level terrain, convenient irrigation and drainage, suitable for the growth of garlic, deep plowed soil, loose fertile sandy loam, and not continuous cropping. Per acre Shi cooked cake fat 100 kg, 2000 tons of quality compost manure or 3,000 kg of manure, superphosphate 50 kg. Then dig a ditch to build a hoe, 畦 width 3 meters, meticulously flat. Garlic requires 150 kilograms per acre. After sowing, fine soil or gray manure is applied for 1 to 2 centimeters, spacing is 20 centimeters, plant spacing is 8 to 9 centimeters, and 40,000 plants are planted per acre. After the sowing of garlic, the leek is spread evenly. The amount of 0.8 kilograms per acre is used to extend the harvesting period and can also be sowed in batches. After sowing, curtains or wheat stalks are spread thinly on the surface to keep the topsoil moist. At the same time, it is necessary to prevent burns and burns at high temperatures and exposures to prevent the topsoil of the soil from being hindered by the seedlings from breaking the soil after the rain.
Third, fertilizer and water management garlic is hi fertilizer crops, especially during the expansion of garlic requires sufficient fertilizer. Usually, in the period of 2 to 3 leaves, 1500 kilograms of rotten and diluted manure or 30 kg of ammonium bicarbonate per acre is applied to the water to raise the seedlings once; the heavy fertilizer is applied 1 times before the winter, ie, the mid-to-late mid-December period. Manure 2000 kg, combined with pouring antifreeze water, in order to increase fertility, protect seedlings through the winter; at the end of March early April and early flower buds and bulbs began to differentiate, topdressing 15 to 20 kg of urea per acre as reminder fertilizer; end of May early May garlic When the leaf sheath is exposed, the quick-acting fertilizer is applied one time, and 20 kg of ammonium bicarbonate or 2000 kg of diluted manure is applied per acre to accelerate the growth of garlic sprouts and promote bulb enlargement. Before the emergence of autumn leeks, the soil is kept moist, and in case of autumn drought after emergence, it should be properly watered, with the principle of light pouring, ground pouring, and cold pouring. Topdressing with nitrogen fertilizer, the principle is light recovery, ground chase, the general top dressing 4 times, the first time after emergence of about 10 days, after the interval of 15 to 20 days topdressing 1 times, each time per acre applied to compost manure fertilizer 1500 kg or 10 kg of urea.
Fourth, to strengthen the prevention of pests and diseases The main diseases of garlic are leaf blight and white rot. Leaf blight frequently occurs on leaves and flower stems. In severe cases, diseased leaves die, and damage to flower stems is easily broken off from the diseased part. Garlic leaf blight: Onset of initial spraying 75% chlorothalonil WP 600 times or 64% anti-tussive WP 500 times, 50% ceric chloride copper WP 500 times, 14% copper ammonia Aqueous agent 300 times, every 7 to 10 days spray 1, continuous control of 3 to 4 times. Garlic white rot: spraying 50% carbendazim WP 500 times or 50% thiophanate-methyl WP 600 times at the beginning of the disease, and 50% acetaminophen WP 1000 to 1500 times Rhizome, especially with 75% garlic leaf green WP 1000 ~ 1500 times liquid spray root, once every 10 days, once every 2 to 3 times, significant control effect. Garlic pods: When larvae occur, 90% trichlorfon 800-1000 times solution can be used in the sprayer. Remove the water from the nozzle and inject the medicine into the root soil to eliminate the early larvae. Also use the enemy in the late growth period of garlic. Hundred insects or phoxim are poured into the garlic field evenly with watering. The main insect pest of leeks is locusts, which can be sprayed with 3000 times of 10% imidacloprid. The main disease is downy mildew, which can be controlled by spraying 75% chlorothalonil 600 times in the initial stage. In the early stage of seedling growth and harvesting period, weeds are removed from the field.
5. Harvesting in batches In early May, when the garlic bulbs have 7 to 10 cm of leaf sheaths exposed and begin to bend, they can pick clear harvests. After 20 days of harvesting the garlic pods, that is, at the end of May and early June, when the leaf sheaths are yellowed and the pseudo stems are soft, you can grab the clear garlic. Leeks are generally harvested in batches about 50 days after sowing. Harvesting should be timely to prevent stems and leaves from aging and reduce quality. Autumn sowing of leeks is generally a sowing, multiple harvest. When harvesting, sharp beveled knives should be used to dig and dig as far as possible to pick large and small, and rare seedlings emerge. Even large plants can be preserved and densely populated, even if they are small, they must be selected so that the remaining trees are easy to send. It grows evenly and evenly in order to increase production and increase income.
