Planting techniques of garlic seedlings in greenhouse

Build a bed: set up with wood, straw, plastic film, iron wire and red brick. | | reasonable close planting: the varieties with high yield, emergence and fast growth are soaked and planted at a density of 150-200 kg per mu. | | Management after planting: keep the light, fertilization can be combined with watering, watering is more in the early stage, and gradually decreases with growth.

Fertilization and pest control of garlic seedlings:

1. Base fertilizer

When producing garlic seedlings in a greenhouse or greenhouse, plant the garlic directly to the ground. Before planting, apply 150000 kg of fine and fine farm manure per hectare, sprinkle it on the ground, turn 20-25 cm deep, mix the soil well, rake flat to make the bed.

two。 Topdressing

When planting garlic seedlings in the greenhouse and applying sufficient basic fertilizer, there is generally no need for topdressing. However, if the lack of nitrogen fertilizer affects growth, ammonium phosphate can be dissolved in water for pouring, topdressing 225-300 kg per hectare. Chemical fertilizer should not be sprinkled directly before watering. In addition, when the seedling height is 20 cm, 200 times ammonium nitrate fertilizer solution can be used to irrigate once, with ammonium nitrate 75-90 kg per hectare; potassium dihydrogen phosphate, high yield element and urea can also be used for foliar topdressing, each time after foliar topdressing, water should be sprayed on both sides to avoid fertilizer damage.

3. Pest control

First of all, we should control the temperature and humidity in the shed so as not to create conditions for diseases and insect pests. Then do a good job of disinfection on a regular basis to reduce the number of pathogens in the shed. If the disease occurs, it is necessary to take corresponding measures, or spray chemicals, or remove the diseased plants.

Garlic seedlings can generally be put on the market about 50 days after sowing. In order to prolong the supply period and increase the output, the plants should be harvested and listed in batches.
