Planting leeks does not require a drop of pesticides, and can safely control larvae maggots, with a double harvest of both yield and quality

Maggots are the number one obstacle to the planting of leeks, and they are also an important reason for the low yield and poor quality of leeks.
In rural areas, pesticides are generally used to control leeks, but the control effect is not ideal, and the pesticides used have a relatively long residual period.
Long, leeks are a kind of vegetables that are harvested many times a year, which causes the phenomenon of excessive pesticide residues in leeks, leading to the failure of most leeks on the market.
All of this is caused by the maggots of leeks
.
Chive maggots are different from other surface pests.
They are often hidden in the roots and roots of leeks.
It is difficult to remove all of them with ordinary medicine, which causes the leaves of leeks to become yellow and dry, which seriously affects the yield and quality.
This also makes many growers feel It's a headache, and it's often at a loss
.
Then I will tell you a good method, which can safely control leek maggots without a drop of pesticides, and has a good yield and quality
.
This method is a new method for prevention and control of leek and leek maggots launched by the Vegetable Academy of Agricultural Sciences.
I only learned it the year before.
I used it several times last year.
The control effect is particularly good.
In the two fields I planted, I used it No leek maggots were found in this method, and the leek grows well, there is no dry tip yellow leaves, and no drug residues.
After being put on the market, after testing, all the leek are qualified and listed as pollution-free vegetables, and the selling price is higher than others.
Leeks are 0.
2 yuan higher per catty
.
This method of the Academy of Agricultural Sciences does not require a drop of medicine.
It uses high-temperature prevention and control methods.
It uses the habit of leek maggots that are afraid of high temperatures and cannot survive in high-temperature environments.
It uses the film-coated warming method to kill all the leek maggots in the ground
.
The method is: on the second or third day after the leeks are cut, choose to use a plastic film with good light permeability to support a small arch shed of 20 cm in height at noon on a sunny day, or spread the film directly on the harvest On the top of the leeks, use soil on all sides to seal tightly, let the soil temperature reach 42 degrees or more, and cover for 4-5 hours, and all the maggots in the ground can be killed
.
In addition to the above prevention and control methods of leek maggots, the planting of leek should pay attention to the management of water and fertilizer.
The fertilization of leek is mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer.
In addition, attention should be paid to the application of sulfur-containing fertilizers.
Foliar fertilizer, spray once when the new leaves grow to about 5 cm after the harvest of leeks, it has a good effect on slow growth, dry tips, yellow leaves, spots, etc.
, and there is no drug residue, which is good for increasing yield and improving quality.
It has a great effect, and we must also pay attention to the combination of organic fertilizer and soil cultivation, which can not only prevent leek from jumping roots, but also promote growth
.
If you want to plant leeks with high yield, good quality, not dry tips, and not yellow leaves, you must do a good job of water and fertilizer management, timely soil cultivation, prevent leeks from jumping roots, and prevent various pests and diseases
.
The above are some formal small methods for growing leeks, I hope to help you, if you have a better method, welcome to communicate
