Generally, the depth of soil preparation and ploughing is about 20cm, which should be carefully ploughed, raked and compacted without obvious obstacles, so as to achieve "neat, loose,

It's broken and clean. "according to the water source, the boundary length can be 80 ~ 100 m long and 4.2 ~ 4.4 m wide; Can also play 40 ~ 50 m long,

The bed width is 4.2~4.4m.

Select seeds, manually peel and break petals, remove garlic trays and stems, and classify according to large, medium, small, garlic core and small garlic petals.

According to the specific situation, the requirements of seed selection are white without red tendons, no scars, saccharification and smooth skin. This principle requires that each capsule weighs about 5g.

Seed size is the key to high yield.

Sow garlic in time. The planting time is at the end of September and the beginning of autumn equinox (65438+1early October), and the temperature is about 17℃. broadcast

Sun garlic cloves 1 0 ~ 2 days before planting.

Reasonable close planting generally has a row spacing of 20cm, plant spacing 16 ~ 17 cm, and about 20,000 plants per 6.67 square meters. The method is to rake or open.

The ditcher ditches, and the depth of the ditch is about 5cm. After planting, garlic is covered with soil of about 1cm. Remember to water when planting.

Tiantuan management

Garlic needs a lot of water for irrigation, and it usually needs to be watered four times during the whole growth period.

(1) Plastic film mulching and watering: garlic should be watered in time after sowing, so that no one plant leaks, and every 667 square meters should be watered 100 cubic meters. this

Secondary water not only meets the needs of garlic planting, but also provides convenience for plastic film mulching.

(2) Strong seedling water: Generally, it should be watered in early April or when the ground temperature is above 15℃.

(3) Moss water: water the garlic moss as soon as it comes out.

(4) water expansion: after pulling out the garlic moss, pour this water.

Plastic film mulching is the key to increase garlic yield, which can increase ground temperature, decompose organic matter quickly and reduce water evaporation.

Garlic's demand for the environment is met. After pouring the film-covering water, the ground still sinks slightly, so use a film-covering machine or manual method to cover the film. whatever

Either way, the plastic film should be tightened and pressed firmly on both sides to prevent the plastic film from being opened when there is strong wind in autumn and winter.

As soon as the young garlic shoots break the ground, they should pierce the plastic film in time to expose the seedlings. Generally, it is used in the morning or evening when the temperature is low and the ground is low.

When the film is elastic, pat it with a new broom or rake it lightly with a bamboo rake.

During the growth period of artificially weeding garlic, the temperature is relatively low, and the harm of weeds is mainly after the Spring Festival. Because it is covered with plastic film, it depends on manpower.

Eliminate. The method is to use thick iron bars or 8mm steel bars to fold the "7"-shaped ditch, break the membrane and eradicate the grass seedlings.

The best time to pull out garlic moss is when the upper part of garlic moss bends from bottom to top. The method is 1 1 every noon.

Gently lift it by hand until 3 pm.
