Cultivation and management of garlic seedlings in greenhouse

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.

It is the green seedling that garlic seedling develops to a certain period, it grows in the farmland, it has the spicy taste of garlic, with its tender garlic leaf and leaf sheath for consumption. Garlic seedlings are rich in vitamin C and nutrients such as protein, carotene, thiamine, riboflavin and so on. Its spicy taste mainly comes from its capsaicin, which has the effect of eliminating accumulated food. In addition, eating garlic seedlings can also effectively prevent influenza, enteritis and other diseases caused by environmental pollution. Garlic seedlings have a certain protective effect on cardio-cerebrovascular, can prevent the formation of thrombus, but also protect the liver. Can grow everywhere, and the output is high and the quality is good. Such as Shandong Linyi and other places large-scale planting, the economic benefit is considerable.

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 to manage the cultivation of garlic seedlings in greenhouse?

Setting up the bed and frame of garlic seedlings in greenhouse

The bed is set up with wood, straw, plastic film, iron wire and red brick. The front and rear of the greenhouse is low and the middle is high, with two floors of beds in the front and rear part and three floors in the middle part. Use a single brick to build a wall with a height of 10 cm, the distance between the walls is 1.2 to 1.6 meters, and then use wooden poles to build a bed with a width of 1 to 3 meters and unlimited length, and the distance between the poles is 20 to 30 centimeters. On the basis of the first floor, a bed 80cm 90cm wide was kidnapped with a wooden pole 80cm 100cm from the first layer. Spread a layer of plastic film on each layer, cover it with sand loam 5 to 6 centimeters thick, and pat the soil solid. In the process of setting up the bed, it must be buried and tied up to prevent the bed from collapsing.

Cultivation and management of garlic seedlings in greenhouse

Selection of garlic species: varieties with large valves, high yield, short dormancy period, seedling emergence and fast growth are selected.

Digging the stem of pickled garlic: soak the garlic seeds in warm water of 30 ℃ ~ 50 ℃ for about 30 hours to make the garlic absorb water and expand. Then remove the drained water and pile it up for about 12 hours, and then dig out the garlic stalks. If the sowing area is large and the soaking amount is large, it can also be sowed one week in advance without digging the stem.

Place garlic to press the soil: about 15 kilograms of garlic cloves are buried every 1 square meter, the tighter the better between the cloves and the cloves, and the larger gap is filled with smaller cloves. After the garlic cloves are set, cover them with fine sand and pat them 3 centimeters thick.

Water management: watering garlic seedlings with water at a temperature of not less than 15 ℃, pouring heavy water after cultivation to the early growth stage, reclaimed water in the middle stage with a height of about 15 cm, and small water in the late growth stage 3-4 days before harvest. The frequency of watering depends on the dryness and wetness of the soil on the bed. Temperature management: it is necessary to keep the film surface of the greenhouse clean and improve the light transmittance so as to obtain more light time. The temperature requirement of setting up the bed is 24 ℃ ~ 26 ℃ in daytime and 20 ℃ ~ 22 ℃ at night, 22 ℃ ~ 24 ℃ in daytime and 18 ℃ ~ 22 ℃ at night, seedling height is about 15 cm, 16 ℃ ~ 22 ℃ in daytime, 16 ℃ ~ 18 ℃ at night, 18 ℃ in daytime and 12 ℃ at night.

Timely harvest: when the garlic seedlings grow to a height of about 35 cm and the leaves tilt slightly, it is the right time for harvest and should be harvested in time. After the first harvest of garlic seedlings, using the same management method mentioned above, new garlic seedlings can grow after 20 days. When the new garlic seedlings grow to about 30cm, they can be harvested and sold again. With this circular management and harvest, 3-4 crops can be harvested continuously.
