Geography aphids, geography, geography how to kill insects

The Eurasian Land Bridge (which in the Asian part of Russia is called the Trans-Siberian Railway.

The European part of the railway network is centered on Moscow and radiates in shape.

In the Asian part, there is only one main railway line in the horizontal direction.

Reasons for the construction of the Trans-Siberian Railway along the southern regions:

1.The low latitude and high temperature in the south are conducive to the construction of railways and have a high safety factor. The temperature in the north is low, there is permafrost distribution, the construction is difficult, and the safety is not easy to guarantee.

2.The population and cities in the south are relatively dense, and the demand for freight is large, which has good economic benefits.

3.The south is rich in mineral resources.

The Trans-Siberian Railway, also known as the First Eurasian Land Bridge!

The Asian part is sparsely distributed only in the southern part of Russia, showing an east-west band, while the European part is densely distributed and distributed in a reticulated pattern.

Because Russia is located at high latitudes, the climate is very cold for most of the year, with a large amount of permafrost, while the south is relatively low latitude and the climate is warmer than the north, so it was built in the south.

In fact, I twisted the second year of junior high school to check the results.

I looked it up back then.

In fact, the three junior high school students can check it first.

Because you only have to take the left two subjects.

School announced!

It's the same You found it and told me I'm going to check it too, I've been on that network a few times, and they all said that there is no information about the candidate.

If geography here refers to underground pests, then 1 phosphine is recommended.

Phosphine is a broad-spectrum organophosphorus insecticide with strong contact killing and stomach toxicity.

It is mainly used for the prevention and control of underground pests, especially for the prevention and control of peanuts, soybeans, wheat grubs and mole crickets.

2 Methylisosulfonate.

Isosulfonate is a soil insecticide, which has a strong contact killing and stomach toxicity effect on cavity fissure pests.

Insecticide has a broad spectrum and a long residual effect period, which is an excellent agent for the prevention and control of underground pests.

Scope of application It is mainly used for the prevention and control of underground pests such as grubs, mole crickets, needleworms and other crops such as wheat, peanuts, soybeans, corn, sweet potatoes, sugar beets, apples, etc., and can also be used to control armyworms, aphids, tobacco worms, peach heartworms, red spiders, etc.

Methylisomerofol is only allowed to be used for seed dressing or soil treatment, and cannot be used for the control of vegetable pests and foliar spraying of fruit trees.

The main goal of establishing a marine special protection area is to protect the resources and ecological environment of specific sea areas, restore and manage the damaged and damaged sea resources and environment, and establish a demonstration area for sustainable marine development with integrated coordination of resources and environment. Located in the intertidal zone of the South Yellow Sea, Oyster Aphid Mountain is made up of live oysters and a variety of marine life. It became the first National Marine Special Protection Area.

The Jiangsu Provincial Marine Fisheries Bureau --- the State Oceanic Administration officially approved the establishment of the Oyster Reef Marine Special Protection Area in Haimen, Jiangsu. This marks the first national marine special protected area in Jiangsu Province. After the field investigation and demonstration of the Nanjing Institute of Geography of the Chinese Academy of Sciences and other relevant scientific research units, it is believed that Oyster Aphid Mountain is the only one in China.

1. It is a rare marine wonder in the world, with extremely high value for scientific investigation and tourism development.

Try to find aphid-eating flies in the corner.

The spawning point, all the eggs are cut out and killed, in order to **.

You can look for the ant hole, and then pour the ant hole twice with boiling water, and then seal the ant hole with cement!!

Aphid-eating flies are beneficial insects. Each small larva can kill thousands of aphids before they develop into pupa, which is beneficial to the plant. Adults are sucking mouthparts that suck pollen and dense flowers, and have the function of helping plants pollinate. It does not sting people and is harmless to people. So please protect it.

I think it's okay to block it and keep stepping on it, this is a protracted war and a water war.

I don't take the high school entrance examination! High school and college are very important. In high school, the liberal arts should study geography; Science requires biology.

In universities, geology, physical geography, geophysics, etc., are all related to the geography of secondary schools; Biology, agronomy, etc., are all related to biology in secondary school. It is advisable not to underestimate geography and biology, which will be of great benefit to you in the future.

Study hard. Right.

Don't think about it so much.

Geography review syllabus for the high school entrance examination.

Seventh grade first volume.

Chapter 1 takes us closer to geography.

1. Unravel the mystery of geography

China: The earliest occurrence of the word "geography" was in the 5th century B.C. Dictionaries

West: The ancient Greek scholar Eratosthenes wrote his first geographical treatise, Geography, in the 2nd century BC

2. Geography and daily life: be familiar with the living environment, confirm the direction, identify the weather, understand the customs, and improve the ability to adapt to life.

3. Geography and production and construction: 1. Geography and agricultural production 2. Geography and construction of industrial enterprises 3. Geography and transportation, commercial outlets, regional planning, solving global problems, etc.

4. Geography and customs: Siberian residents, carnival, Christmas, bullfighting, Arab costumes, etc.

Section 2: How We Learn Geography.

1. Learn to read maps: 1. Map making process: bird's-eye view of graphics--- floor plans--- maps (P6).

2. The earliest map: Sumerians dating back more than 4,700 years.

3. Map type: (P7).

Second, the three elements of the map:

1. Direction: 1) Usual method: up, north, down, south, left, west, right, east.

2) Mapped with pointers: arrows point north.

3) There is a graticule map: the meridian line indicates the north-south direction, and the latitude line indicates the east-west direction.

4) Look at the map outdoors: face north and back face south.

5) Determine the direction of the ground plane: compass; Polaris; Sun; Annual ring; Dense foliage; The degree of humidity on both sides of the mountain.

You add me baidu hi, I sorted out ** very comprehensive, you can see if it's okay.

Are you in = =, speed to ask me for information = =.

In fact, it is not necessary to get some review materials for the review of biology and geography, as long as you memorize all the knowledge in the book.

You can use your memory and knowledge to make two structural tables, one biological and one geographical. Then, after the list is finished, check the book to see what else has been forgotten and make up. Then fold the corners, these are the main points when reviewing.

Biology: Mainly memorize some scientific observation concepts, methods, etc., and also know the reasons for each step of the experiment.

Geography: In two steps. Step 1: Natural environment (including topography, range, rivers, climate, etc.) Step 2: Economy (including industrial areas, industries, crops, agricultural areas, human environment, economic forms, etc.).

I am now a student in the second year of junior high school, and I am also facing the entrance examination, which is the revision method taught to us by our teacher.

As for some topics, you can go to the bookstore and buy some books such as top student training to practice.
