Planting method and time of garlic seedlings in greenhouse

The leaves of garlic seedlings are bright green, neither yellow nor rotten, the hairy roots are white and do not wither, and they are spicy, so they are indispensable condiments in dishes. At present, it is common to plant garlic seedlings in greenhouse. So, what is the planting method and time of garlic seedlings in the greenhouse?

First, build a bed

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 10 cm high wall with a distance of 1.2-1.6 meters, and then use wooden poles to build a bed with a width of 1-3 meters and unlimited length, with a distance of 20-30 centimeters. On the basis of the layer, 80-100 cm from the layer is kidnapped into a bed 80-90 cm wide with a wooden pole. Spread a layer of plastic film on each layer, cover with 5-6 cm thick sandy loam, 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.

Second, choose garlic species

The varieties with large petals, high yield, short dormancy period, seedling emergence and fast growth were selected. It is usually planted in spring and autumn.

III. Pre-broadcast preparation

The varieties with large petals, high yield, short dormancy period, seedling emergence and fast growth were selected. Soak the garlic seeds in 30 ℃-50 ℃ warm water 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.

Fourth, laying garlic to press the soil

About 15 kilograms of garlic cloves are buried per square meter, and the tighter the better between the cloves and cloves, and the larger gap is filled with smaller cloves. After the garlic cloves were set up, the garlic cloves were covered with fine sand with a thickness of 3 cm, and the surface was sprayed with 600-fold liquid of new high-fat membrane to improve the seedling emergence rate.

5. Water management

The garlic seedlings were watered with a new high-fat membrane diluent with a temperature of not less than 15 ℃, followed by heavy water from 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 and light

It is necessary to keep the film surface of the greenhouse clean and improve the light transmittance so as to obtain more light time. Spraying photosynthetic nutrient film fertilizer can help garlic seedlings absorb a lot of light energy, and have the nutrition of conventional fertilizers, so that the growth and development of garlic seedlings is better.

7. Timely harvesting

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 stubble garlic seedlings are harvested, 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 such circular management and harvest, 3-4 crops can be harvested continuously.

The vitality of garlic seedlings is relatively strong, so it is not difficult to plant, and about 50 days after sowing, fresh and tender garlic seedlings can be harvested in batches and listed on the market.
