How to water garlic planting?

In early spring, the temperature rises and the seedlings begin to grow. At this time, garlic field watering depends on soil moisture, which can be mastered flexibly. There is much rain and snow this year, and the soil moisture is good. You can start watering in early March. Watering in early spring should not be too early, watering frequency should not be too frequent, and watering amount should not be too much, in case watering lowers the ground temperature and affects the early growth of garlic. After April, garlic entered the peak water demand. As the saying goes, "garlic stands in April", which is the reason. Therefore, in this period, it is necessary to meet the water demand of garlic and keep the soil moist frequently until 5-7 days before harvest.

Garlic needs a lot of water, 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 kind of 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: water after pulling the garlic bolts.

Sandy loam is the best way to grow garlic. Garlic grown in sandy soil has a strong spicy taste, but its texture is loose and it is not resistant to storage. Garlic root system is shallow, hairy, weak in water and fertilizer absorption, and not tolerant to drought and flood. At different growth stages, garlic has different requirements for water and fertilizer. Today we will talk about the water and fertilizer management of garlic.

First, water the garlic.

Autumn sowing garlic has a long growth period, and it needs to be watered at least 4-5 times during the whole growth period. According to the water demand of different growth stages of garlic, watering can be distributed in the following periods.

1, the whole seedling stage.

The germination period of garlic needs high soil moisture to promote early rooting and germination. After planting garlic in autumn, seedlings can emerge in 7- 10 days. At this time, according to the soil moisture, if the ground of garlic seedling field is dry and hard, you can water it once.

2. Seedling stage.

The temperature is low in winter in the north. In order to improve the freezing resistance of garlic, overwintering water can be poured once to reduce the harm of low temperature to garlic by increasing soil moisture. This watering can't be too early or too late. If it is too early and the temperature is high, it is easy to cause garlic to grow too fast. Water too late, if the soil has frozen, it will aggravate the freezing damage.

3. Green period.

After the Spring Festival, garlic entered the green period, the underground roots began to develop rapidly, the leaves began to turn green, grew bigger and thicker, and entered the vigorous growth period. Leaves are elongated, garlic moss is elongated, and garlic is swollen. This is the first water demand peak of garlic. At this time, we should cooperate with topdressing and water once to promote the rapid growth of garlic.

After garlic turns green, with the rapid increase of temperature, the weather becomes windy and dry. Should be watered once or more according to the actual situation, and topdressing in time, in order to promote the growth of garlic leaves and make the stems thicker.

4. bolting period.

The differentiated leaves of garlic seedlings have all been exposed, the growth of leaf area has reached the peak, the root system has also expanded to the maximum extent, and the growth of garlic bolts has accelerated. This period is the period when the amount of fertilizer and water is the largest, and bolting water should be poured in time after fertilization. After the "tail show", it is necessary to continue watering to promote seedlings, and stop watering for 2 ~ 3 days before harvesting to facilitate storage and transportation.

5, garlic expansion period.

Water and topdressing garlic bolts immediately after harvest to promote the rapid expansion and weight gain of garlic. In the later stage of garlic bulb development, the water demand decreased rapidly, so watering should be controlled to promote the maturity of phosphorus stems and improve the storage resistance of garlic. 7 days before garlic harvest, watering should be stopped to control the growth and accelerate the transportation of assimilated substances from leaves to garlic.

Second, garlic topdressing

Garlic topdressing should be carried out according to soil fertility and the needs of different growth stages, and the principle of topdressing should be grasped to prevent excessive growth in the early stage and premature aging in the later stage.

1, seedling stage.

After the seedlings grow completely and before overwintering, if the base fertilizer is sufficient during soil preparation and sowing, there is no need to topdressing. If the base fertilizer is insufficient or the seedling emergence is not good, a small amount of quick-acting fertilizer can be combined with watering to cultivate garlic seedlings, and the amount of fertilization must not be increased to avoid unnecessary growth.

2. Green period.

The following spring, when the average temperature reached above 7℃, garlic seedlings began to turn green. At this time, the plastic film should be removed in time and the seedlings should be exposed to the sun for 2-3 days. Before the trees grow around the vernal equinox, 1 time should be applied to turn green. Generally, topdressing organic fertilizer1000-1500kg or standard nitrogen fertilizer10-15kg per 667m2.

3. The young garlic shoots stretch for a long time.

From the beginning of garlic petal differentiation to bolting, garlic bolting and garlic grow together, and garlic is in a vigorous growth period. At this time, all the leaves have grown out, and the growth of the aboveground parts of plants has reached the maximum. The yield of garlic underground has reached nearly 50%, the root system has actively expanded to the side, and the growth and absorption have gradually reached the peak. It is necessary to apply more compound fertilizer and potassium fertilizer to promote garlic bolting and garlic swelling.

Second, garlic topdressing

Garlic topdressing should be carried out according to soil fertility and the needs of different growth stages, and the principle of topdressing should be grasped to prevent excessive growth in the early stage and premature aging in the later stage.

1, seedling stage.

After the seedlings grow completely and before overwintering, if the base fertilizer is sufficient during soil preparation and sowing, there is no need to topdressing. If the base fertilizer is insufficient or the seedling emergence is not good, a small amount of quick-acting fertilizer can be combined with watering to cultivate garlic seedlings, and the amount of fertilization must not be increased to avoid unnecessary growth.

2. Green period.

The following spring, when the average temperature reached above 7℃, garlic seedlings began to turn green. At this time, the plastic film should be removed in time and the seedlings should be exposed to the sun for 2-3 days. Before the trees grow around the vernal equinox, 1 time should be applied to turn green. Generally, topdressing organic fertilizer1000-1500kg or standard nitrogen fertilizer10-15kg per 667m2.
