How to water garlic in winter?

In recent years, garlic freeze injury has occurred from time to time, resulting in garlic production reduction. For example, the winter temperature in 20 15 was very low, and large-scale garlic freezing injury occurred in Jinan, Jinxiang and Taian, Shandong Province. The mortality rate of garlic seedlings in severely damaged and lightly frozen plots is about 30%, while that in general plots is 40%-60%, and there is no production in severely damaged plots.

Farmers in many places have experienced the "garlic is at its end" in 20 17 years, but garlic farmers decided to take a gamble, hoping to become "garlic is cruel" in 20 18 years, and they all chose to plant a few acres.

Recently, however, garlic growers are in trouble again. Many growers, because last year was the first time in kind of garlic, watered their crops inappropriately a few years ago. So many people consult some experts and ask whether garlic was mixed with water years ago. How to water it? The best time to water, the results obtained three different opinions. I don't know what to do. Let's see:

Will garlic be watered before winter?

The first statement:

Garlic should be watered 1 times in the middle and late seedling stage, and the seedlings grow vigorously, so it should be watered in time to promote the growth of garlic leaves. Before the soil is frozen, it is necessary to pour enough wintering water, and only after pouring enough wintering water can the seedlings be safely wintered.

The second statement:

Garlic is generally not watered before winter, and it is watered after turning green manure in the following year. This watering is very important. Let the soil dry and wet alternately, which is more conducive to the growth of garlic. If you water too much, you are prone to diseases.

The third statement:

Garlic is an overwintering crop. Just like wheat, it is necessary to irrigate garlic with overwintering water reasonably and carefully, so that garlic can overwinter safely. When watering, you should choose a sunny day after three to five days of continuous freezing, and then seal the soil. The time should be after 10 am and before 4 pm. It is forbidden to flood the land with water. Cleaning the floating soil on the plastic film in time is beneficial to fully absorb sunlight and save ground temperature.

After listening to these three statements, many growers still don't know whether to water them. Can garlic farmers water their friends? Pay attention to the micro-signal huobao3456tv and express your opinions!

For everyone's high yield, let's share the water demand law of garlic growth cycle:

When is garlic watered?

Garlic is carefully watered at seedling and early growth stage. According to past experience, seedlings should grow fully within one week after sowing, and fertilization should be applied at the same time.

If the soil is dry, water should be poured once to promote the growth of seedlings; Seedling stage is the key period for the differentiation and formation of garlic vegetative organs. Do not water or do it to prevent flooding, and pay attention to timely drainage in the field after autumn rain. If the drainage is not timely, it is easy to cause garlic seedling death.

Garlic can be watered 1 time in the middle and late seedling stage, and the seedlings should be watered in time to promote the growth of garlic leaves. In addition, organic fertilizer can be applied at one time with watering, which is beneficial to the thickening of garlic pseudostems. Before the soil is frozen, it is necessary to pour enough wintering water, and only after pouring enough wintering water can the seedlings be safely wintered.

Because the ability of garlic root system to absorb water and fertilizer is weak, some biological bacterial fertilizer and appropriate quick-acting fertilizer should be applied at seedling stage to avoid yellowing of garlic tip. Generally, nitrogen fertilizer can be applied once after garlic seedlings are fully grown, but urea should be avoided to prevent seedlings from burning.

The best time to water garlic.

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.

So garlic needs to be watered four times during the whole growth period.

1, plastic film mulching watering: garlic should be watered in time and thoroughly after sowing, so that no one plant leaks, and every 667 square meters should be watered 100 cubic meter. 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 in early April or when the ground temperature is above 65438 05℃.

3, moss water: garlic moss just came out and poured this water.

4, soaking water: after pulling out the garlic moss, pour this water.

How to water garlic?

Although garlic leaves have strong drought tolerance, their roots are shallow and their absorption capacity is weak, so garlic has higher requirements for soil moisture, and different growth periods have different requirements for soil moisture.

1. Garlic keeps high soil moisture after sowing. If it is too dry, water it in advance so that the soil moisture is suitable for sowing. Generally, water is not watered before winter, so as to promote roots and squat seedlings.

2. After applying garlic green manure in the second year, the top water should be poured, which is the key to improve the yield of garlic bolts and garlic.

3. Keeping the soil dry and wet at garlic seedling stage can promote the development and growth of root system.

4. After garlic seedling stage, the demand for soil moisture increased gradually, and reached the peak at bolting stage and bulb expansion stage. This is what the agricultural proverb "eat garlic mixed with mud" says.

5. 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.

When garlic is watered, what fertilizer is applied for high yield?

Want to high garlic yield, garlic can't be watered early, whose garlic is watered early, whose garlic is small!

After the Spring Festival, garlic entered the green period, the underground roots began to develop rapidly, and the leaves began to turn green, growing bigger and thicker, showing strong growth potential. We can use enzymes to add trace elements to leaves 500 times, 10 once a day;

After March 25th, garlic entered a vigorous growth period, with leaves stretching, garlic moss growing and garlic swelling, which is a stage of vegetative growth and reproductive growth. At this time, it is time for garlic to start watering. Garlic field should not be watered too early in spring, and the watering time can be decided according to the local actual temperature.

Water for the first time, apply 8- 10 kg of new no-tillage irrigation fertilizer per mu (667 square meters) to treat underground pests;

Water for the second time, and apply 40kg of quick-acting high-nitrogen no-tillage functional compound fertilizer per mu (667m2). If the third watering is needed, the new no-tillage irrigation fertilizer 100kg can be continuously applied, and the total nutrient trace element fertilizer and high-efficiency fungicide 1000 times can be sprayed on the leaves every two months.

Prevent the occurrence of garlic rust, powdery mildew, scab and leaf blight, and ensure the urgent demand of garlic for various nutrients in the reproductive growth period. A single garlic plant has a leaf width of 4 cm, a tip height of 1.4 m and 240 roots, which is regarded as the second growth and development standard of 4000 kg garlic.

It can grow moss early, quickly, more and more, and increase the yield by about 200 kg per mu. Stop watering 3-5 days before bolting to increase the toughness of garlic moss and facilitate bolting. When the rolled leaves of garlic moss inflorescence extend out of the leaf sheath 13- 16 cm, the garlic moss is harvested.

Garlic moss can't be harvested too early. If harvested too early, garlic seedlings will grow many leaflets, causing garlic lobular disease. After picking garlic moss, garlic swelling water should be poured in time and 8 kg of high-quality no-tillage potassium sulfate should be applied. At this time, 150 times of total nutrient micro-fertilizer and 500 times of high-efficiency bactericide should be sprayed on the leaves every seven days to protect the leaves from premature aging and promote garlic expansion.
