Efficient cultivation techniques for garlic bulbs listed before and after the Spring Festival

First, build a room with soil. Choose irrigation conditions, fertile soil, sunny leeward, non-green onion, leeks, etc. to build a greenhouse. Cultivation beds are mainly framed beds and general seedbeds. Either way, you should first spread 3-4 cm thick garden soil on the bed surface. Use 55% of high-quality farmyard fertilizer, 5% ammonium sulfate, 6% phosphate fertilizer and 30% of the screened garden soil to mix evenly on the garden soil of the cultivation bed, about 4-5 cm thick.

Second, soil preparation and fertilization. In recent years, garlic bulbs have been used in solar greenhouses before and after the Spring Festival. Before planting, apply 667 square meters of high-quality rotting and sifting farmyard fertilizer to 1,000 kg, deep-dip 20 cm, mix the loam and soil, and treat the crop. Sand beds can also be constructed on a flat surface, ready for river sand, and small stones are screened out, spread 5-6 cm thick.

Third, select seed varieties. The garlic varieties that produce garlic are more precociously selected than the earlier-maturing varieties, ie, white-skinned dog garlic, and can also be selected from Cangshan garlic, Anqiu garlic, Hangzhou big white peel, horse tooth garlic, Jiaxiang garlic and other garlic varieties.

Fourth, pick the garlic. 1 kilogram of medium garlic can produce 2 kilograms of garlic, producing up to 2.2 kilograms; the production of garlic is too small. The diameter of garlic is generally 4-5 cm. Must choose white, solid, spicy garlic head, in order to make the garlic growth thick.

5. Carefully cut garlic. Cut garlic should be noted that in the early winter, when cutting garlic, because of short heart buds, you can stick the neck scissors, you should remove the old garlic sprouts, and the remaining part can be taken out again when the roots are cut. In this way, the knife can not be cut when cutting garlic, the seedlings can be cut equally, and it is also convenient for homework.

Sixth, cultivation time. In northern China, garlic sprouts can be planted at any time from mid-July to early February. The time for planting garlic is determined according to the supply period. Generally, it takes 20-25 days after planting garlic to receive the first knife, and then closes the knife every 15-20 days. Therefore, the supply of garlic sprouts before and after the Spring Festival is generally better planted on New Year's Day.

Seven, dipping the roots of garlic. Before sowing, first cut the garlic with cold water for 12-24 hours. Generally, it can be foamed until it touches the skin. After soaking, remove the water on the curtain, then cover the grass for 8-10 hours. It can also be soaked in warm water of 45°C for 2-3 hours, then cold water bubbles for shorter time. When soaking garlic, 0.07 kg of ammonium nitrate can also be added per 100 kg of dried garlic to promote the growth of garlic sprouts. After dipping the garlic, dig up the root and remove all the old and old roots on the garlic. If you don't dig it out, the sprouts of the garlic sprout first and then the old roots get sucked out of the seedlings, delaying 3-4 days before the seedlings emerge. Digging the old and old roots of garlic can emerge in 1 week, and it will take 10 days to dig without digging. When rooting, you can use a flat awl to insert the garlic root. If you force it, the old root will fall off and it will not disperse. If you don't use garlic bulbs to dig up old roots, you will not only dig the nets, but often cause the garlic to fall.

Eight, planting garlic watering. To put a head of garlic close to the cultivation bed, the gap should be used with loose petals, so as not to waste the bed. Per square meter can be planted 15-20 kg of dried garlic. The above should be as flat as possible. Garlic should be matted to a small size. After it is planted, it should be leveled with a wooden board and watered. After the water seeps, it is covered with 5-6 cm fine sand to facilitate moisturizing and harvesting. When the seedlings grow up to 12-15 cm long, pour water; pour 3-4 days before harvest.

Nine, control the temperature. 4-8 days after garlic planting should be maintained at 22°C-24°C. 5-6 days before harvest should be maintained at 18°C-20°C. The night temperature throughout the growth period is not lower than 16°C-18°C, the bed temperature should be maintained at 18°C-20°C, and the room temperature should be maintained at 25°C-28°C. It should be noted that when the temperature is as high as 28°C to 30°C or lower than 15°C to 16°C, the garlic sprout tip will appear yellowish.

Ten, timely harvest. 20-30 days after planting, the seedlings are harvested when they are about 40 cm high. If you want to cut the second knife, after the first knife cut flat sand, and when the cut should be light should not be heavy; to be the second time after the garlic seedlings were sprayed, spray a 5% of ammonium sulfate fertilizer, then spray 2 times clean water rinse garlic, Other management is the same as above, about 20-30 days, when the garlic grows to about 30 centimeters, two knife harvest is carried out. After harvest, remove the garlic mother.
