1. If it is a simple glass greenhouse, it is related to the sun: sunlight is divided into: solar short-wave radiation and ground long-wave radiation.

The solar short-wave radiation can pass through the glass to reach the ground, but after reaching the ground, it is absorbed by the ground and reflected by the ground in the form of ground long-wave waves to achieve the heat balance of the ground. However, the long-wave radiation from the ground cannot pass through the glass, so it is reflected to the ground. So the temperature in the greenhouse is getting higher and higher.

If it is a greenhouse for plants: on the one hand, the air is not circulated and convection, and the heat can be dissipated. In addition, in order to create a greenhouse, flower farmers or vegetable farmers will make some smoke in the greenhouse to increase the carbon dioxide content of the greenhouse.

Everyone knows that global warming is associated with an increase in carbon dioxide.

2.To give an example; The early rice in the south of the Yangtze River will enter the sowing period, and all localities should adopt the method of keeping warm seedlings to prevent the impact of low temperature and rainy weather"Cool tail warm head"The fine weather is timely for sowing.

In the central and northern parts of South China, it is necessary to speed up the sowing progress of early rice, and to do a good job in the management of seedling fields in the south.

South and western China should actively look for water sources and do a good job in fighting drought so as to ensure that early rice is planted in a timely manner.

3. The greenhouse can cause the greenhouse effect, which makes the temperature in the greenhouse rise. Create a suitable temperature and humidity conditions for the plant to grow. Fruits and vegetables can be grown in winter as well as in summer.

1。Glass can effectively block the long-wave radiation on the ground through the short-wave radiation of the sun, thus playing the role of a greenhouse;

2。Master the occurrence law of the inverted spring cold, and listen to and use the inverted spring cold weather forecast. It is necessary to seize the "cold tail and warm head" in the process of weather evolution to seize the sunny and sow seeds.

Generally, the average daily temperature reaches 12 °C, the minimum temperature is not lower than 5 °C, and there are 3-5 sunny days (more than 3 hours of sunshine per day) after sowing, which is conducive to early rice sowing and seedling raising.

Strengthen field management and improve farmland microclimate conditions. Carry out scientific drainage and irrigation of early rice seedling field, carry out deep water seedling protection when the spring cold comes, and adopt "night irrigation and day drainage" and "sunny drainage and rain irrigation" to adjust the water and heat conditions of the seedling field.

In areas where conditions permit, greenhouse steam or soilless seedling raising can be adopted, so that the whole process of early rice seedling raising is completely under artificial control to ensure the cultivation of strong seedlings of appropriate age.

3。The main thing is the modification of the temperature, followed by the humidity.

This question means that when you look at the places of the four cities, after changing to Beijing time, if you are not in the period from 6:09:41 to 12:49:31, you can be stupid**. Now is known Beijing time, need to change to four cities of the place, aThe 3rd East District of Moscow is 5 hours away from the East Batath Orange District, which is 5 hours away, and the local time is 1h 9 41 to 7h 49 31 c

Sydney East Zone 10, 8:09:41 to 14:49:31 bNew York's West 5th District, 13 hours away from the East 8th District, 6:9:41 minus 13, not enough to subtract, you need to borrow a day forward, become 30:9:41 on the 5th, and then subtract 13, that is, 7:9:41 on the 5th in New York, and the interval in Beijing is 6:39:51, so New York is 0:29:51 to 7:9:41 dRio West Zone 3, the same as above, 2:29:50 to 9:9:41 on the 5th At this time, the northern hemisphere is June, the southern hemisphere is in winter, and at this moment Rio is in the middle of a long dark night and early morning

The annular solar eclipse and the 15th Beijing time began from western Central Africa at 13:13 Beijing time, passed through the map (India) into China, and passed through Yunnan, (Sichuan), Guizhou, Chongqing, Hubei, (Henan, Henan), Anhui, Jiangsu and Shandong and other provinces and cities, and ended at 16:59 on the Shandong Peninsula. (3 points).

The first question, where a waterfall can be formed, must be relatively high and steep. Where the contour line is dense, it is steeper. Then choose one of the two in A and B.

Is it A or B? Waterfalls need water, right? There is water in the valley.

Draw two lines, intersecting at one point. The height of this point is between 700 and 800, and less than 800, indicating that the terrain is low. for the valley.

Otherwise, for the ridge. So the answer b

Question 2: Water flows downward. The only way to divert water from the height to the bottom is to the bottom, or between the same heights. Depict the height of A, B, C, D, and compare them separately, only D is eligible.

The third question, the same scale, depends on the contour distance. a 5 b10 c 10 d 10 e50.The greater the contour distance, the steeper it becomes. The contour distance is the same, depending on the degree of density. From this, the answer comes out.

Fourth, just look at the scale. The larger the scale, the steeper the slope.

Fifth, high pressure points to low pressure, south left and north right. The airflow deviates to the right, in the Northern Hemisphere.

Question 6: Low pressure trough, the air flow rises, forming rainy weather.

Question 7, the first step, connect points of the same height. a. The slope depends on the density of the contour lines. B steep. b. The temperature depends on the altitude. High altitude and low temperatures. C The temperature is low. d Altitude, C high. Choose C.

Question 8: Trees are related to temperature, light, precipitation, etc. In the question, there is abundant precipitation and dense forests.

1. The formation of a waterfall satisfies the presence of steep cliffs and valleys, and the contour line at B bends to the heights to form a valley 2.

3. d Look at the density of contour lines at the same interval.

4. The slope of the large scale is large.

5. The airflow deviates to the right.

6. The northwest airflow flows towards the center and rises, forming a rainy weather.

7. B is located on the east side of the mountain range, on the windward slope.

8. Good water conditions.

9. A high-pressure ridge, no front b The northern hemisphere low-pressure trough, the cold air force is strong, forming a cold front C The southern hemisphere low-pressure trough, the warm air force is strong, forming a warm front d The northern hemisphere low-pressure trough, the warm air force is strong, forming a warm front So choose B

Only the third question? : The third question says that the scale in the figure is the same, and the comparison slope is to see who is steeper at the same distance, so choose a fixed distance (1) and then according to the contour line you can know the height difference between the distance on the 1 and the height difference of each place, which is obviously e, and the height difference of each contour line is 50m, which is also the largest.

1.The convex height is low, and the contour line overlaps into a steep cliff, which may be a waterfall.
