How to cultivate garlic seedlings in greenhouse to achieve high yield

Garlic sprouts, also known as green garlic (garlic yellow when there is no light). The flower moss of garlic consists of two parts: the flower stem (moss stem) and the involucre (bract). The moss bud is the involucre at the top of the flowering stem of garlic, which contains underdeveloped inflorescences. The garlic seedlings with good quality should be fresh and tender, the plant height is about 35 cm, the leaves are bright green, neither yellow nor rotten, the hairy roots do not wither, and the spicy taste is strong.

Morphology of garlic seedlings

Garlic, a perennial herb, has a strong garlic stench. Bulb large, 6-10-merous, enclosing grayish white or lavender on membranous scale. Leaves basal, solid, flattened, linear-lanceolate, about 2.5 cm wide, sheathlike at base.

Flower stem erect, ca. 60 cm tall; involucre long beaked, 7-10 cm long umbel, small and dense, with bracts 1-3, segments 8-10 cm long, membranous, light green flowers small, interflower mixed with reddish bulbs, 4 mm long, or completely without beads; pedicel slender, longer than flowers; perianth 6, pink, elliptic-lanceolate; stamens 6, white, anthers prominent. Pistil 1, style prominent, white, ovary superior, long elliptic-ovate, apex concave, 3-loculed. Capsule, 1-locular dehiscent. Seeds are black. Flowering in summer.

Growth habits of garlic seedlings

Like warmth, strong cold tolerance, it is appropriate to plant in spring, summer, autumn and winter. Garlic is widely distributed in China, mainly in North China, Northwest and Northeast China.

How can garlic seedlings be cultivated in greenhouse with high yield?

Select and build greenhouse

Choose good irrigation conditions, fertile soil, leeward to the sun, non-green onions, leeks and other hot stubble land to build a greenhouse. Prepare the cultivation bed

The cultivation bed is mainly a frame bed and a general seedling bed, and garden soil 3-4 cm thick should be spread on the bed surface first. Select garlic species

The large white-skinned varieties with large head, multi-lobed and high yield were selected, the yield of purple-skinned garlic and large-peeled garlic was low, and the quality of garlic seedlings was poor. Put the selected garlic into a jar and soak in clean water for 2 days, absorb water and expand. Preparation of nutritious soil

Use 55% high-quality farm fertilizer, 5% ammonium sulfate, 6% phosphate fertilizer and 30% sifted garden soil, mix and spread evenly on the garden soil of the cultivation bed, about 4cm thick. Put garlic to remove the soaked garlic seeds, dig out the old roots, dig out the stem plates and stubble columns, and put them on the cultivation bed, the denser the better; the garlic cloves are filled with loose cloves, and the garlic buds are all upward; 15 to 17 kilograms of garlic seeds are placed per square meter; finally, the garlic seeds are covered with fine sand, and the thickness is appropriate to bury the garlic tip, then compacted with wood and watered through the bottom water. Control temperature

22 ℃ ~ 24 ℃ should be maintained 4-8 days after planting garlic, 18 ℃-20 ℃ should be kept 5-6 days before harvest, night temperature should not be lower than 16 ℃ ~ 18 ℃, bed temperature should be kept at 18 ℃ ~ 20 ℃, room temperature should be kept at 25 ℃ ~ 28 ℃. It should be noted that when the temperature is as high as 28 ℃ ~ 30 ℃ or below 15 ℃ ~ 16 ℃, the tip of garlic seedlings will appear yellowing. Appropriate watering

When the seedlings grow to 12-15 cm after emergence, they should be watered and watered 3-4 days before harvest. If the indoor temperature is slightly higher, the watering times should be slightly more. Harvest and plant garlic

After 23-28 days, when the garlic seedlings are slightly dumped, the head knife should be harvested, which can produce 1.7-1.8 kg garlic seedlings per 250 grams of garlic seeds; after the second crop of garlic seedlings come out, spray 5% ammonium sulfate fertilizer solution once, and then spray clean water to rinse the garlic seedlings twice, other management is the same as above; about 20-30 days, when the garlic seedlings grow to about 30 cm, carry out two-knife harvest. After harvest, the garlic mother is removed and garlic production is rearranged. Generally, 3-4 crops can be produced every winter and spring.
