2. Garlic enters the peak water demand after April. To meet the water demand of garlic, the soil should be kept moist frequently until the watering is stopped 5-7 days before harvest.
3. Garlic needs a lot of water, and it usually needs to be watered four times during the whole growth period. It should be noted that the mulched water and garlic need to be watered in time after sowing, and the water is poured thoroughly, so that no one leaks. The water not only meets the needs of garlic planting, but also provides convenience for covering with plastic film. Strong seedling water is usually watered in early April or when the ground temperature is above 15℃.
Extended data:
1, plastic film mulching is the key to increase garlic yield, which can increase ground temperature, decompose organic matter quickly, reduce water evaporation, and meet garlic's environmental needs. After pouring the film covering water, the ground still sinks slightly, and the film is covered with a film covering machine or manual method. Either way, the plastic film should be tightened and pressed firmly on both sides to prevent the plastic film from being uncovered when there is a strong wind in autumn and winter.
2. Garlic varieties can be divided into purple garlic and white garlic according to the color of bulb skin. The garlic cloves of purple garlic are few and large, with strong spicy taste and high yield, which are mostly distributed in North China, Northwest China and Northeast China, with weak cold tolerance, sowing in spring and late maturity. There are two kinds of white garlic: large petals and small petals, which are less spicy, colder than purple garlic, sown in autumn, and mature slightly earlier.
3. Garlic stem: Bulb is large, with 6 ~10 petals, and covered with off-white or lavender in membranous lodicule. The leaves are basal, solid, flat, linear-lanceolate, about 2.5 cm wide, and the base is sheath-shaped. Flowering stems erect, about 60 cm high.
4. Garlic leaves: including leaf body and leaf sheath. The leaf sheath is tubular, and the leaves are folded before exhibition, but flat and long after exhibition, which are parallel veins. Leaves alternate, with 1/2 leaf order and symmetrical arrangement. Leaf sheaths are nested with each other to form pseudostems, which have the functions of support and nutrient transportation.
5, garlic root: shallow root crops, no root. Hair roots are around the shortened stems, with the most on the outside and less on the inside. The longest root can reach more than 50cm, but the main root groups are distributed in 5-25cm soil layer, with a transverse range of 30cm. The number of roots per plant is 70- 1 10.
6. Garlic is not strict with soil, but fertile loam rich in organic matter, loose and breathable, with strong water-retaining and drainage performance is more suitable.
