(1) The reason is rainy weather (2 points). The weather suitable for harvesting is sunny, which only means that there may be cloudy or low-intensity precipitation, which is more suitable for harvesting; The picture on the right shows that most areas in this area are suitable for sowing, which meets the conditions for sowing after precipitation (4 points).

(2) The latitude in this area is low, and it is still increasing at the end of 10 (2 o'clock). Crops in this area are harvested two or three times a year, and the harvest in summer is late (4 points). In other areas, due to high latitude or altitude, the growth period is short and the harvest is early (4 points).

(3) Transportation and market: the market demand for flowers and vegetables has expanded and changed due to the acceleration of transportation (3 points); Science and technology and product benefit: With the continuous progress of science and technology, the economic benefit of planting flowers and vegetables is higher than that of planting mulberry (3 points).

Test analysis:

(1) According to the material: "The best weather for grain harvest is sunny, so that it can be dried in time. Before sowing winter wheat, if there is precipitation process, it will help to increase soil moisture and be suitable for sowing and seedling growth. " The picture on the right shows that most of this area is suitable for sowing, and it meets the conditions suitable for sowing after precipitation, so there is precipitation weather in this area, and the weather suitable for harvesting is sunny, which only means that there may be cloudy or low-intensity precipitation, which is more suitable for harvesting.

(2) The main factor affecting crop growth is climate conditions. The latitude of P is low, and 10 is still increasing at the end. Crops in this area are harvested two or three times a year, and they are harvested later in summer. In other areas, because of high latitude or altitude, the growth period is short and the harvest is early, one crop a year or three crops every two years.

(3) The location factors affecting agriculture mainly include natural conditions, socio-economic conditions and technical conditions. Natural conditions include climate, topography, soil and water. Socio-economic factors include market, transportation, government policies, labor force, land price, etc. Market demand ultimately determines the type and scale of agricultural production. Transportation and market: with the acceleration of transportation, the market demand for flowers and vegetables has expanded and changed; Science and technology and product benefit: With the continuous progress of science and technology, the economic benefit of planting flowers and vegetables is higher than that of planting mulberry trees, which leads to the transformation of agricultural model.
