High quality cultivation methods of garlic for export

The quality of garlic for export is required to be high, and scientific cultivation methods can ensure the quality of garlic.

First, sowing choose soft, fertile, good drainage sandy soil, watering before planting plow rake, apply enough cake fertilizer, human excrement and other farm manure. Garlic should not be planted on the plots where the previous crops were onions and leeks. Select medium-sized garlic seeds with few petals, no mildew, disability and insect infestation, and garlic seeds with petals cannot be planted. Sowing before and after the autumnal equinox, using a narrow hoe to open shallow trenches for dibbling, and then covering the soil with flat, consistent depth is required. 30,000 plants per mu, plant spacing 11.7~13.3 cm, row spacing 20~23.3 cm, seeding rate 100~125 kg per mu.

II. Field management ① After sowing to around the beginning of spring, do a good job of Qi Miao, strong seedling and safe winter management. Sandy soil should not be irrigated after sowing until emergence; sticky soil should be watered within 5 days after sowing, and topsoil should be properly raked after watering. When the seedlings are 13 cm high, hoe the soil between the rows of pine trees. Hoeing should be done both after watering and after rain. Water less after winter. After the winter solstice, the soil was watered once before it was frozen, and then farmyard manure was applied to a thickness of about 6.6 cm. Apply urea 10 kg or ammonium nitrate 30 kg per mu of green fertilizer. After the vernal equinox, garlic needs more fertilizer and water, so urea and other quick-acting fertilizers can be applied with water irrigation.② Garlic sprouts and cloves grow rapidly after Qingming to grain rain, so it is necessary to keep the soil moist. Stop watering 5~6 days before bolting.③ Garlic growth will be affected if it does not bolt or bolting is not complete. When harvesting garlic sprouts, thick iron needles should be used at a distance of about 15 cm from the ground to cut off garlic sprouts. Hold the base of garlic sprouts with one hand and gently pull out the sprouts with the other hand.④ Watering once every 3~4 days after harvesting, applying urea 15~20 kg per mu, and stopping watering one week before harvesting garlic. 5. Garlic harvest should be carried out before and after small fullness, not too early or too late. Harvesting garlic should not be pricked, bruised or broken garlic skin.

Third, pest control pay attention to rotation, avoid applying undecomposed fertilizer (especially human excrement). Application of pesticides during soil preparation to kill underground pests. The garlic maggots were drowned by flood irrigation in the plots where garlic maggots occurred. Serious insect pests occur, with dichlorvos or dimethoate 2000~3000 times spray control.

Fourth, after harvest processing garlic harvest to avoid rain, sun, timely classification selection. According to the garlic diameter is divided into 6 cm or more, 6 cm to 5 cm and unqualified (5 cm or less) three grades. Cut the garlic reaching the export standard with a knife for 3~4 knives in circles along the root part, cut the root part clean, make the root part slightly convex, dry it and collapse here, not easy to scatter petals. Garlic should be tied or braided in time, hung in a ventilated place, dry and stored. Before selling garlic around the end of June, cut off the 1.5 cm stalks of dried garlic, remove the old skin of garlic outside the soil, and make it fresh, clean and complete.
