Where are the rice locusts, that is, grasshopper seedlings in rice fields? And the approach to the b

A large pile in the field, caught with a net or by the phototaxis of insects.

1. Site selection. Choose a ventilated, sunny place.

2. Eliminate natural enemies.

Before building a shed, use methods such as catching, trapping, boiling water and scalding to eliminate ants and crickets on the ground, because the above animals are the natural enemies of locusts, and can prey on locusts and destroy locust eggs, so these animals must not be allowed to exist in the shed.

3. Ground. The floor of the shed should be 10-15 cm higher than the surrounding ground to facilitate drainage during the rainy season. The soil is best sandy loam, which is not easy to agglomerate, easy to lay eggs and retrieve eggs, and the burden is not too soft, and the requirements for locust laying eggs are very high.

4. Density. The size of the shed depends on the number of locusts, but generally 600-800 adults can be raised per square meter.

5. Build a shed. According to your own conditions, you can use wooden sticks and bamboo chips to build a stand for a shed. Then according to the size of the scaffold, make a canopy like a mosquito net with gauze, hang it on the scaffold, bury the bottom edge in the ground, leave the doorway, press the zipper on the door, this installation is to prevent the locusts from running out and facilitate the feeding and management of the shed.

The height of the shed can be meters, in order to keep warm or rainproof, the outside of the shed can be covered with plastic sheeting. When the temperature is high and the locusts are large (more than three instars), they are not afraid of rain, and they can not be covered with plastic sheets. If the natural conditions are used to breed locusts, the construction of the sheds must be completed by the end of April.

Generally, the egg mass is laid in the ridges, barren beaches, embankments and other soils, centimeter deep or weed roots, and overwintering between rice stubble. In the spring of the following year, the young nymphs swarmed after egging. Feed on the grasses around the field, begin to disperse after 3 instars, move into the field as a pest, use the medicine in the peak period of the young nymphs, mix with 20 30 liters of water and spray evenly, including the weeds around the paddy field to apply pesticides and control.

Exterminate rice locusts before they spread. Remind rice farmers to pay attention to the application of pesticides in paddy fields, focusing on spraying weeds around the edges.

We farmers should pay attention: after harvesting, we can put the straw in the field to create a good living environment for spiders; or to collect the spider egg sacs found before and after harvesting in a safe place to protect them; You can also use ducks to eat locusts, and the effect is also good. Nowadays, China has perfect prevention and control measures in dealing with the locust plague, such as biological control, chemical control, and pathogenic microbial control, which can effectively eliminate locusts.

Pathogenic microorganisms that have a targeted effect on locusts can greatly limit the number of locusts and their ability to swarm.

To reduce the habitat of locusts, some locusts occur in low terrain, we can transform such plots into ponds, fish and shrimp, so that the locusts can be greatly reduced, and locusts will be better controlled. Biocontrol. Use natural enemies to control insect population density.

The natural enemies of locusts include birds, frogs, beneficial insects, mites, pathogenic microorganisms, etc. It is necessary to create more environments conducive to the survival of natural enemies and increase the number of natural enemies.

Diseased locusts also lay eggs with microsporidia. The disease can spread among locust swarms through food contamination and locust biting each other, creating a long-term epidemic, just like the flu. Therefore, after a single control, the disease can be endemic in locust swarms for many years.

Dicotyledons such as soybeans are also fed when hungry. The main habitats are extensive cultivation, low-yield (overgrown) crop land, reed land, wasteland, reservoir area, saline-alkali tidal flat and other locust suitable habitats.

The use of biological pesticides for control, currently used for the control of locusts are locust microsporidia, Metarhizium aeruginosa and neem. Microsporidia locusts are locust-obligate, single-celled protozoans. Locusts can cause microsporidiasis when they feed on food with microsporidiasis.

The first is to choose a rice variety that is resistant to insect pests, and secondly, it must be sprayed.

Some pesticides should be sprayed. Some pesticides can wipe out rice locusts.

Speaking of leeches, I was bitten by leeches in my childhood. Native country dolls, who have been collecting rice with adults since they were young, are almost everywhere in the rice fields in the south. Every time you come ashore after working in the rice field, there will be a few leeches hanging on your calves, and you will already find that these leeches are eating drums.

Once they are pulled out, blood from the calves will run down. After the beginning of autumn, the weather is getting cooler and cooler, and the rice in the fields is also yellow, and the crops must be recovered when the "autumn tiger" comes! Rural areas have to eat according to the weather, and many times they have to grab the weather.

It's like harvesting rice. When the weather is good, the crops should be dried so that the rice in the field can be recovered. If you miss this weather, when it comes to the rainy season, the whole family may not have food to eat all year round.

The process of harvesting rice is not easy. There is a great sun overhead, and there is water under your feet, but there are insects in this water. Locusts, i.e. locusts, are specialized in sucking blood.

If left unchecked, several locusts can crawl on two feet. It's a mollusk that can suck blood in its veins. And you don't feel it sucking blood from your feet at all, this thing is scary, but can only live in fields with water, and some fields don't have it.

My home is in the Qiulin area, and most of them have water, so every time I hunt crops, I am most afraid of locusts, but I am afraid, and there is no need to be afraid if there are preventive measures. Won't approach you at all. Let me teach you how to prevent locusts from sucking blood!

1.You can wear long pants, the longer the better, a pair of dry rice pants, the kind that can cover the whole foot, and the dry rice pants do not stick too much mud, suitable for wearing millet, and locusts do not come to look for them.

That's a great way to do it! 2.It is best to use tobacco leaves at home to rub tobacco oil on your feet and then on your feet.

In this way, grasshoppers will not come close when they are wearing pants. The grasshopper is most afraid of the smell of smoke, so it won't come. 3。

It is a simple and effective way to apply wind oil essence or cool oil to the calves that are commonly used at home to prevent locusts from approaching! If you are accidentally bitten by a locust, you can gently pat the bite with your hand. Locusts falling down can disinfect wounds and prevent infection!

It is not easy to grow rice in rural areas. There are grasshoppers in rice fields, such as water grasshoppers and dried grasshoppers! In short, keep an eye out for locusts on your feet at all times.

Locust fluid has an anesthetic effect on the human body, and you don't feel pain at all when biting, so you should observe it anytime and anywhere!

How to sprinkle table salt :

** is the first protective barrier of animals, and mollusks (including locusts) are not**, after sprinkling salt, salt and its body fluids form a high concentration of saline, which promotes the extravasation of low concentration of body fluids inside, resulting in its dehydration and death.

Grasshoppers mainly suck the blood of animals and reproduce quickly in water. There are also grasshoppers in damp woodlands, and the woodland grasshopper bites people very painfully and itchy. Now there are few locusts in the fields, and they are mainly killed by pesticides and fertilizers.

Grasshoppers are most afraid of lime pesticides and fertilizers, which is the nemesis of grasshoppers and the most effective.

<>1. Select the variety.

There are many kinds of grasshoppers, and the adaptability and resistance of grasshoppers are very strong, we can artificially breed cotton locusts, East Asian locusts and other varieties, each species has different breeding advantages and disadvantages, among which our most common breeding species is the East Asian locust, but it is not suitable for everyone to raise, when choosing varieties should be carefully considered according to various factors such as growth time, the number of eggs spawned, body size, breeding environment, market demand, etc., the different varieties determine the direction of breeding and even the market. So we have a realistic approach to choosing varieties.

2. Site construction.

First of all, we have to build the breeding site in the sunlight is stronger, good ventilation place, Jiankai shooting when the farm is higher than the ground, convenient for later drainage, grasshoppers are usually in the soil for spawning, so we should choose suitable for grasshoppers to lay eggs sandy soil, and then spread a layer of leaves on the ground, easy for grasshoppers to eat, the area of the farm determines how much and density we breed, pay attention to the closure of the farm, to prevent grasshoppers from escaping, grasshoppers will have devastating harm to crops after escaping, Do a good job of waterproof and rainproof measures to prevent excessive water from drowning grasshoppers when it rains.

3. Feeding management.

After the establishment of the site, the locusts can be directly put in, the locusts will begin to mate and lay eggs, the young grasshoppers will gradually hatch after laying eggs, and they will begin to change their skins about 6 days after hatching, this time is the critical period for the growth of young grasshoppers, there must be enough feed to ensure that the young grasshoppers successfully peel their skins, if not enough, it will lead to problems with the growth of grasshoppers, and even the failure of changing skins, and there is a certain danger, there will be various problems such as eating big and small, being bitten, so we must pay attention to it, when the grasshoppers successfully change their skin five times, It is almost mature, and at this time some of the egg-laying grasshoppers are left, and the rest can be caught and marketed.

4. Prevent escape.

Grasshopper is a kind of insect that is very harmful to crops, and other special industries are completely different, although artificial breeding will make it produce greater value, but also increase the number of grasshoppers, including a fierce increase in hidden dangers, so in the process of breeding must do a good job of anti-escape measures, around the breeding site to set up an isolation zone of insecticides, prepare a sprayer in the field, find that there is an escape phenomenon and spray in time to kill, to prevent harm to the external environment.

Grasshoppers in rice fields can be eliminated by using salt, chemical fertilizers, tobacco bag oil, quicklime, and plowing and exposing rice fields in autumn and winter. I recommend ploughing the paddy fields in autumn and winter, and using quicklime.

The grasshoppers in the field can be caught and sold for money, so that farmers can increase their income, and the grasshopper is commonly known as leeches, which have strong medicinal value; In autumn and winter, the paddy fields are ploughed and exposed to the sun, and quicklime can also be used to eliminate locusts, and the residue left after the rural soil presses the shelled peanuts can be used in the field, which can be used to kill insects and fertilize the fields.

You can use quicklime and chicken blood to get rid of locusts; I recommend using chicken blood, which can be placed in the grass to attract the locusts and destroy them all.

You can take a look at it, I plan to raise it too!

The prevention and control of rice blast is an important task in rice production. This work is a systematic work that cannot be done by medication or drying the fields alone. Prevention should be the mainstay, supplemented by the best, and work should be carried out in an all-round way.

According to the survey, the rate of diseased leaves in the field is between 2% and 5%. In the plots where the leaf blast occurred earlier, the phenomenon of leaf scorching has appeared.

<>Compared with the same period in previous years, this year's rice blast came relatively early. However, the local incidence is severe. Put an end to all causes of the rice plague.

Qingjianghe believes that the early occurrence of rice blast this year is mainly due to weather reasons. Under the conditions of saturated air humidity and suitable temperature, pathogens invade quickly, and rice can become sick in about a week. In areas where the temperature drops and where there is more rain and fog, it is more suitable for the epidemic and spread of rice blast.

What's even more ridiculous is that when checking the situation in the Heming community in Qingjiang, a farmer saw that after the rice went up the mountain due to rice blast, he also used urea"Seedlings"Isn't this a strange practice that backfires? For the occurrence of rice blast, in addition to the cultivation density, fertilization level, and planting technology management, the selection of varieties should not be underestimated. The selection of disease-resistant varieties should be planted rationally, and non-disease-resistant varieties should be planted in a large area in a certain local area, which is easy to cause the epidemic of rice blast.

In addition, the amount of nitrogen fertilizer should be controlled, the shallow water layer of the field should be maintained, and the humidity in the field should be reduced as much as possible. Remove weeds at the edge of the field and increase the ventilation and light transmission of the field. Scientific fertilizationScientific application of nitrogen, phosphorus and potassium fertilizers to improve the stress resistance of rice.

Finally, chemical control should be strengthened after the initial lesions of rice blast were found in the field. Commonly used drugs are rickavid, chunleimycin, rickvenjing, rickvenbi, rickvenling, rickvennuo, etc. 1. Rickvenjing single dose, rickwenbuzole, pyraclostrobin and other compound preparations have good prevention and control effects.
