In the summer, it is best to water potted leeks once a few days?

Potted leeks need to be watered every morning and evening to meet their need for water to grow. However, it should be noted that there should be no stagnant water in the pot, otherwise it will easily lead to root rot and seriously affect the growth. If it is placed in a cool place, the amount of watering can be reduced.

Potted leeks are commonly placed on the balcony of the house or the side of the house, as the sun rises and sets, these places also get half a day's light, not a whole day of exposure, like the front of the balcony of the house to get the morning light, the morning light is relatively weak, and then gradually increases, the water vapor evaporates from less to more, but after noon, there is no sun, that is to say, the exposure lasts for a short time, the potted soil is still relatively moist, do not need to water every day, depending on the situation, water once every day and a half or 2 days, Water early in the morning or in the evening before the sun rises.

Leeks are leafy vegetables, water vapor evaporates quickly, the leaves lose more water, and the leaves rely on the root system to absorb water to transport upward, the root system of the small plant is not developed enough, the water absorption is relatively less, the leek plant is more, the water absorption is more, the leek is watered in the summer to see the growth of the plant, the small plant is also watered every day, but the small watering does not have obvious water, the upper layer of soil that is watered for 2 days is relatively dry and the heat transfer is fast, and the small leek seedlings are easy to be damaged under the heat.

Watering once every three days is enough, and each watering should not be too much, so that the taste of leeks will be better and more tender, and the vitality is also very tenacious.

If it is placed outdoors, the sun is sunned all day and night, after all, the soil in the pot is limited and the moisture retention will be poor, and it should be watered once in two to three days.

Water in a timely manner according to the moisture of the soil. If the seedlings grow strongly, they can not be fertilized to facilitate squatting seedlings and prevent the seedlings from lodging. In years with high precipitation, pay attention to flood prevention and drainage.

You can water, leeks do not need to be watered too early in spring, basically above 0 degrees, when the day freezes and the night disappears, you can water, mainly watering small water.

1. Leek watering time.

According to the actual situation of watering, the adaptability of leeks is relatively wide, leeks are cultivated in various parts of our country, there is a difference in temperature between the north and south of our country, how much precipitation, the distribution is more uneven, if there is more rain and snow in winter, the soil moisture is large, after the beginning of spring, the moisture in the soil can fully meet the needs of leek growth, this time do not carry out watering, the first water in spring can be arranged for watering time after the first leek is cut.

Winter rain and snow is less, spring is more prone to drought, the water content of the soil is too little, is not conducive to the growth of leeks, although leeks are root vegetables, the root system stores the nutrients of the previous year, but the lack of water will still grow badly, at this time you can have gooseskin jelly at the beginning of the spring night, melt during the day, water the leeks again on a sunny day, the watering is not too big, you can pass by, most of them are watered back to green water in late February.

2. Precautions.

Leek growth needs a lot of nitrogen fertilizer, in addition to the winter topdressing base fertilizer, it is best to topcoat urea when watering, urea can be sown in advance with chemical fertilizer, and then covered with soil, watering at an interval of about 5 days, can significantly improve the utilization rate of nitrogen fertilizer, the utilization rate of urea flushed with water, not as high as the utilization rate of burying with soil.

It is more convenient to flush with water, in the case of sufficient use of base fertilizer, every other stubble of leeks, it is best to flush with water once urea + Yanwo potassium dihydrogen phosphate, which is conducive to the growth of leeks and improves the yield of leeks.

OK. Leek maintenance method.

1. Temperature: Leeks are suitable for growing in warm places. Specifically, it is more appropriate to keep it at 15 to 25 degrees.

In addition, when breeding, the temperature should not be lower than 12 degrees, otherwise the breeding is easy to fail. In winter, try to keep it slightly warmer as well.

2. Light: Its negative resistance is better, however, in order to promote its growth, it is better to maintain moderate intensity of sunlight. However, when the light is very strong, the quality of the leeks will deteriorate, so it is necessary to block the light slightly.

3. Watering: It is a more moisture-loving variety. The moisture of the soil should be slightly higher, but try not to exceed 80%, and not accumulate water. In addition, the air humidity should also be properly monitored, and it is better to have it at 60% or 70%.

4. Fertilization: Leeks are also a fertilizer-loving plant, and their fertilizer tolerance is also relatively good. Usually, you can pay more attention to fertilization, you can apply water-soluble fertilizer for vines and leaves, and the base fertilizer of the soil can not be less.

According to our northern season, it is possible to water now, but more often. Leeks should be watered frequently, but not every day.

Leek planting management:

1.Temperature. Greenhouse planting leeks, the initial temperature should not be too high, the temperature is controlled at 19-25 degrees during the day, the temperature is controlled at 6-11 degrees at night, the minimum temperature can not be lower than 5 degrees, if in the case of high temperature and high humidity, it is easy to cause gray mold, resulting in root rot, when the leek growth environment is higher than 28 degrees, we must pay attention to the ventilation and humidity of the greenhouse.

2.Humidity. In the planting process, we must keep the soil moist, the aboveground part dry, the underground moist, and timely ventilation after each watering, which should be controlled below 80%, so as to prevent the appearance of gray mold, especially in the vigorous growth period, must not lack water.

3.Illumination. Leeks do not have high requirements for light, and the rhizome part of the leek can also grow in the dark.

4.Fertilize. Before planting leeks, it is necessary to turn the soil deeply, apply foot fertilizer, and pay attention to the combination of organic fertilizer and inorganic fertilizer, the ratio is 1:

1 is more appropriate, about fertilization, need to take into account the growth of leeks and the humidity of the soil, weather conditions, when do not use too much fertilizer at a time, to use less many times, in the later stage of leeks to be suitable for the application of green water-soluble fertilizer.

2. Field management.

1.Juvenile. Leeks from the beginning of the seedling to planting, it takes about a month and a half, when the first leaf grows, feed the seedling stage of the leek, at this time the growth is relatively weak, you can spray some stress-resistant auxin to enhance the stress resistance of the leek, absorb more nitrogen, strengthen photosynthesis, so that the seedlings can grow better.

2.Vegetative period. After planting, the leeks begin to germinate and differentiate, and the demand for nutrients increases. Therefore, foliar fertilizer is used regularly for leeks, which can continuously promote the growth of leeks, and when there is a split root, it must be cultivated.

3. Pest control.

1.Physiological diseases. There are many physiological diseases of leeks, including rotten leaves, yellow leaves, rolled leaves, etc., mainly due to the excessive use of fertilizer, resulting in the dry tips of leeks, and the dry tips of leeks caused by abnormal temperatures.

2.Bacterial diseases, fungal diseases. Most of the bacterial diseases and fungal diseases occur in the summer of high temperature and rain, mainly affecting the rhizomes and leaves of leeks, especially the root damage is more obvious, and the stems are also prone to occur.

For example, gray mold will cause leeks to produce lesions at night, causing the leaves to wilt, and when the ground is damp, leeks are also prone to grow lesions, producing green or white mold.

3.Pest. The insect pest is mainly leek maggot, mainly because of the heavy stubble, it will make the stem rot leaves yellow and die, it can occur 5 to 7 times a year, especially in spring and autumn, it is more obvious, so spray some insect repellent on a sunny day to carry out root irrigation control.

4.Epidemic disease. This disease mostly occurs in greenhouse planting, which will lead to a decrease in leek yield, strengthen field management in the planting process, reduce soil moisture, cultivate soil in time, strengthen ventilation and moisture drainage, watering should be watered small points frequently, and plant ash can be used to reduce humidity when the disease occurs.

Leeks can be watered in the spring, but not too often. In order to allow leeks to grow, there is a relatively high temperature, spring general watering does not need to be too early, mainly watering, when the temperature reaches more than 0 degrees, when the night freezes and the day disappears, you can carry out watering. Let's take a look at the relevant knowledge.

Leek cultivation method.

1. When is it good to sow leeks?

When we sow seeds, we must know the appropriate temperature conditions for seed germination. Although the germination of vegetables is affected by temperature, humidity, light, etc., we believe that temperature is the main factor affecting seed germination.

The temperature requirements for leek seed germination are very strict, the minimum temperature of germination is 2-3, the suitable temperature is 15-18, under the suitable temperature conditions, the germination is particularly fast, only 6-7 days can emerge, but below or higher than the suitable temperature, the seed germination is significantly slower, and even 15-20 days to emerge.

The suitable temperature for the growth of leek seedlings is 15-25, and the temperature of seedling growth is higher than that of seed germination, and autumn sowing can not only take into account the temperature of germination, but also take into account the temperature of seedling growth.

According to the temperature of seed and seedling growth to choose the sowing time of leeks is appropriate, the north is generally sown in spring and autumn, sown around the beginning of summer in spring, seedlings emerge quickly, grow well; In autumn, it is more appropriate to start sowing after the white dew.

2. Sowing method of leeks.

1) The land preparation should be particularly fine.

Leek seeds are bow-shaped unearthed, the ability to unearth is very weak, the requirements for the soil are very strict, if the soil is compact, hard, or even rough will affect its emergence. Therefore, the plot of sowing leeks should be particularly fine, and the bottom moisture should be made before the land preparation, and the soil should be ploughed several times after turning the ground, so that the soil is soft. Make a flat furrow to be sown.

2) The covering soil should be thin but the humidity should be maintained.

It is also because the ability of the bow to be unearthed is very weak, so the covering soil should be thin. Leeks are generally sown in strips, the row spacing is 30-40cm ditching, watering in the ditch, sowing after water infiltration, and covering soil 2-3cm. Due to the plantation moisture, no watering is required after the sowing is completed, and if the planting area is small, cover with mulch or straw to moisturize and emerge faster.

If there is no mulching, it is necessary to pay attention to keep the soil moist during the emergence of seedlings, and to drench water in time during drought, and it is best not to flood the irrigation with large water, which will affect the emergence of seedlings.

OK.

Leeks do not need to be watered every day. Water once a week is enough to keep the soil moist, as leeks are prone to root rot in long-term waterlogged soil. While maintaining leeks, it is also necessary to provide them with sufficient light to maintain the normal growth of leeks, and can also provide mineral-containing water and balanced nutrition for leeks, so as to improve the growth rate of leek plants and make leeks grow more vigorously.

1. Reasonable fertilization, leeks will consume a lot of nutrients in the growth process, so when maintaining leeks, you need to provide sufficient nutrients for the plants, you can provide nitrogen fertilizer for the leeks during the vigorous growth period, and you can also provide phosphorus and potassium fertilizer for leeks in daily maintenance, so that the plants can better absorb nutrients.

2. Leeks like to grow in a warmer environment, so when maintaining leeks, they also need to provide them with sufficient light, so that they can photosynthesize, remember to pay attention to the light intensity when providing light to leeks, and shade leeks in time when the light is too strong, so that the plants can grow healthily.

3. When maintaining leeks, you can water the plants with fungicides every three days to eliminate the bacteria in the soil.

How to water leeks.

1. Watering frequency.

Leeks like water, but not tolerant to waterlogging, when breeding leeks, if watering too often, it will cause the plant to rot in water, and if watering too little, it will cause the leek branches and leaves to wither yellow and slow growth, it is best to water every 4-5 days to promote the vigorous growth of leeks.

2. Water quality conditions.

When watering leeks, you can provide them with non-polluting well water, rainwater or mineral water, provide the plants with the water they need to grow, so that the growth rate of leeks is accelerated, if you want to use tap water, you should place it in the sun to dry for 1-2 days to remove chlorine in the tap water.

3. Watering method.

When cultivating leeks, it is necessary to let the water flow into the soil along the edge of the pot and flow out from the drainage hole at the bottom of the pot to completely soak the soil and maintain the normal growth of the leeks, and when the ambient temperature is higher than 35 degrees, spray water mist around the leeks to improve the humidity of the air.

4. Precautions.

When watering leeks, you can apply fertilizer to them once, you can choose nitrogen, phosphorus and potassium compound fertilizer or well-rotted organic fertilizer, so that the yield of leeks becomes higher, and the leeks should be placed in a bright place to promote their photosynthesis and make the leaves of the plant more green.

In summer, leeks should be watered once every 7 days, and each watering should be combined with topdressing fast-acting nitrogen fertilizer urea or Bika amino acid water-soluble fertilizer of 20 kg per mu, and the number of irrigation should be increased during drought. After the frost falls, the temperature gradually decreases, the plant grows slowly, and the nutrients in the plant are converted to the bulb and root system.

At this time, the amount of irrigation should be reduced, so that there is no drought and no watering, in order to prevent the green from returning to the root slowly, stop watering and fertilizing at the end of September, promote the return of nutrients, in mid-November, the temperature drops rapidly, the ground part gradually withers, and the plant enters the dormant period, at this time to remove weeds.

In order to avoid watering after the shed, reduce the ground temperature and make the soil moisture sufficient after the shed, then the freezing water should be poured once. Combined with frozen water, each mu was irrigated with kilograms of trichlorfon to reduce the harm of leek maggots after buckling the shed.
