How to use pesticides correctly in the process of growing leeks?

1.Reasonable combination of pesticides, do not unscientific random matching.

2.Before spraying, dissolve the pesticide with a vial, and then pour it into a sprayer containing one-third of the water, shake it evenly, and then spray, otherwise it is easy to cause pesticide damage.

3.When spraying pesticides, they should be sprayed evenly, and should not be sprayed repeatedly because of serious diseases, otherwise pesticide damage will easily occur.

4.The temperature should be appropriate when spraying, and it is easy to cause pesticide damage when spraying at high temperature, so it is recommended to spray at about 10 o'clock in the morning or after three o'clock in the afternoon.

The following points should be paid attention to when using herbicides in leek fields: Before sowing or before sowing and before seedling, a contact herbicide 20% paraquat can be used, 150-250 grams per mu, 50-70 liters of water are added, and evenly sprayed on the ground, the weeding effect is significant, and if it is used after the emergence of leeks, it will cause pesticide damage. It can also be used to treat the soil with 100 grams of 50% promethofen per mu; 33% weeding can be used for weeding at the seedling stage, 150 grams per mu, no less than 50 liters of water, evenly sprayed on the furrow surface, and 48% fluoralin can also be used to use 150-200 grams per mu. After each stubble of old root leeks is harvested, remove the weeds in the field, after the wound heals, water it once, and then spray it, generally use it twice a year, and use 170 grams of 33% weeding per mu each time.

When using drugs when leeks have insect infestations, it is necessary to choose special drugs for leeks and spray them at a suitable time period, so that they can not harm the leeks and remove insect pests.

We can use a small watering can to spray leeks with pesticides, and when spraying pesticides, we must dilute the pesticides, and do not water them within two days after spraying pesticides.

After the leek is harvested, the fertilizer can be topdressed, but it is necessary to stop the topdressing in time when the new leaves grow 2 3 cm after the leek wound heals after harvesting, and 20 kg of urea per mu is applied. If it is managed well, the second knife can be harvested 28 to 30 days after the first knife of leeks is harvested, and the third knife can be harvested 25 to 28 days after the second knife.

Leeks in the spring before the green to clean up the leek on the surface of the dead leaves in a timely manner, after the end of the row to stop the subsoil, when the leeks began to germinate, it is proposed to apply a thin manure per square meter 750 1500 grams, to 3 4 days after the beginning of the ploughing loose soil to do silver 1 time, at this time ordinary do not water, if the soil moisture is good, can be watered after the first knife of harvest, after insisting on the soil surface to see wet and dry.

After each watering, it is necessary to cultivate the loose soil, and after harvesting 3 days per square meter to apply 2000 3000 grams of decayed human feces, it is necessary to apply it with water or stop furrowing, and it is necessary to avoid topdressing and watering immediately after the leek harvest, so as to prevent the formation of fertilizer or disease through novel wounds. After the leeks are harvested, the ashes should be evenly sprinkled on them. It should be noted that spring is the peak period of leek maggot attacks, and special attention needs to be paid to prevention and control.

Leeks are not harvested in the summer under normal conditions, and should be drained in time when encountering high temperature and rain. After the summer heat, continue to beat the sprouts, apply the appropriate amount of dilute manure water, increase the supply of fertilizer and water to the leeks in autumn, reduce the number of harvests, and prevent leeks and maggots in time. After the heat to maintain the air is not dry, watering is 7 10 days watering, at the same time with the water to apply 750 1200 grams of dilute human feces, after the cold dew must control the number of watering, or to maintain the surface wet and dry, then stop the top dressing, and then from the heat to the autumn equinox, and then harvest 1 2 knives, stop watering and top dressing in time, after the autumn equinox to stop harvesting leeks.

Timely watering of the frozen water before freezing.

Leeks can be top-applied fertilizer, but it is best to apply farmhouse fertilizer, the application of farmhouse fertilizer must be rotten, sprinkle grass ash in time after harvesting, do not harvest too often, to prevent root damage.

After the leeks are harvested, they can be fertilized immediately. In the countryside, the chicken manure raised by the family is the most lacking to pick up good, in the rural home, when each batch of leeks is harvested, it is harvested on the ground with a sawtooth knife, immediately after harvesting, take the chicken manure raised by their own go-raising macro soil chicken manure, apply a layer of chicken manure to cover the leek root surface after the flat cut, 2 to 3 days later, the new leek seedlings are marked, the weather is warm and grows faster, less than 10 days and half a month, and the second batch of leeks can be harvested, the leeks after the application of chicken manure are large and green, used to give birth to leeks to match the fish to eat fish more flavorful. Foodies may wish to give it a try!

Vegetables should be fertilized after harvesting as leeks are a vegetable that feeds on leaves. A buried void year can harvest a lot of cherry holes, spinal fluid withered. Soon after each harvest, the leeks are able to grow to the proper height for harvesting.

As a result, there is a high demand for fertilizers after harvest. After each harvest, the leeks are fertilized and watered to improve the quality and yield of the leeks.

Leeks are a vegetable that can be harvested repeatedly and can be harvested when it grows up. Reasonable fertilization of leeks after harvest is not only conducive to the faster leaf growth of leeks, but also can supplement the fertility of the soil.

First of all, some pesticide residues are volatile, so after buying fresh leeks, it is best to place them in a ventilated place for 1-2 days before eating.

Secondly, soak for a period of time before eating, and add an appropriate amount of baking soda (edible alkali) to the water when soaking. Because leeks generally use organophosphorus pesticides, one of the characteristics of organophosphorus pesticides is that they are inactivated when exposed to alkali. Appropriate edible salt can also be added, because the soaking of brine can cause the leek cells to precipitate pesticide residues due to shrinkage and water loss.

After soaking the leeks, wash them with water before eating.

Thirdly, cut off the leek root about a centimeter in length before eating. Because pesticides must be applied to the roots of leeks to remove pests, the pesticide residues in the roots of leeks are the largest, so it is better to remove pesticide residues by cutting off part of the leek roots when eating.

Leeks processed by the above methods can become a delicious food on the table.

However, there are also several taboos in eating leeks, which are not suitable for everyone. Leeks belong to the spicy and warm heat-boosting products, eating too much is easy to get angry, indigestion, so mouth and tongue sores, yin deficiency and fire, gastrointestinal weakness, people with eye diseases should not eat leeks. Leeks should not be eaten raw; In addition, overnight cooked leeks should not be eaten again.

The advice of pesticide people is to eat less or even no leeks, unless they are grown without pesticides. Because pesticides are watered from the beginning of sowing to kill leeks, highly toxic pesticide residues are not generally high. How to pick leeks?

First, look at the color, don't pick the one that looks particularly green; Second, look at the size, don't choose a particularly stout one; Third, look at the leaves, don't be particularly thick. If you like to eat leeks, then bathe leeks more: because the pesticides currently used are organophosphorus, which are soluble in water, soak them in water after buying them back, and wash them with water more to reduce pesticide residues.

Summary. Hello, you can use methyl toludamine 800-1000 times liquid, spraying the temperature should be appropriate, high temperature spraying is easy to cause pesticide damage, it is recommended to spray around 10 o'clock in the morning or after three o'clock in the afternoon.

What pesticides are used for leeks that do not grow well? What fertilizer to sprinkle.

Hello, you can use methyl toluminemine 800-1000 times liquid, spraying the temperature should be appropriate, high temperature spraying is easy to cause pesticide damage, it is recommended to spray after 10 o'clock in the morning or after three o'clock in the afternoon.

The organic matter content of cow manure is low, the fertilizer efficiency is slow, although the nutrients of chicken Nian Yanfeng manure are the highest, but the insufficient chicken manure contains a lot of insect eggs, which is very tolerant of jujube cavity and easy to provoke underground pests. Although pig manure is a well-balanced manure, its efficacy is far inferior to sheep manure.
