What are the factors that affect crop growth and yield?

The diurnal range of temperature and light has an important impact on the yield and quality of crops. High temperatures and strong sunlight during the day favor the photosynthesis of crops.

Weakened, reduces energy consumption, and is conducive to the accumulation of nutrients. For example, Northwest China.

The climate is early and dry, the sun is abundant, the sunshine is strong, the heat capacity of the sandy soil is small, the temperature rises rapidly in the strong light during the day, and the heat dissipation at night is also very fast, so that the temperature changes sharply, and the daily variation range of the summer temperature is very large: the melons and fruits in Xinjiang are particularly sweet, which has a lot to do with it.

High-quality seeds can effectively increase crop yields, and fertilizers can effectively increase crop yields and eliminate pests. Relatively little land is required, but large amounts of continuous use can shorten the life of the soil. Using agricultural machinery instead of manual sowing and harvesting can save time, reduce labor costs, increase efficiency, and achieve greater yields.

The development of agriculture in the future must be inseparable from mechanization.

Monsoon climate. The summer is high temperature and rainy, rainy and hot at the same time - conducive to the development of rice cultivation; The summer monsoon is unstable – most of them are early waterlogging disasters, and water conservancy facilities need to be built. Mediterranean climate.

Summers are hot and dry, with strong sunlight, rain and heat at different times – irrigation needs to be solved, which is conducive to horticulture and fruit planting. Temperate oceanic climate.

The rainfall is uniform throughout the year, but the heat is insufficient, which is not conducive to the ripening of cereals, but is conducive to the growth of succulent pastures, which can be used for the development of dairy farming. Temperate continental climate.

The climate is dry, the solar radiation is strong, and the temperature difference between day and night is large, so it is necessary to solve the problem of irrigation, which is conducive to the production of high-quality agricultural products, such as temperate fruits, cotton, etc.

Crops thrive in well-lit places, but most crops thrive in places with little or no light. High temperatures also have a great impact on crop growth. Crops that ripen in areas with good heat conditions will also be higher than those with poor heat conditions.

Water is the source of life. Crops need water to grow.

Organic fertilizers are rich in organic matter and nutrients needed for crops to grow. They can not only provide the nutrients needed for crop growth and improve the soil, but also improve crop quality, increase crop yield, promote high and stable crop yield, maintain soil fertility, and improve fertilizer efficiency.

For example, climate, temperature, including rainfall, and geographical location, are also related to the cultivation techniques of farmers, and are related to the sunshine time and terrain.

The yield of crops is affected and constrained by many factors. First of all, it is affected by the natural environment. Light, water temperature, soil fertility, etc. will affect crop yields.

Factors that affect the growth and yield of crops include weather, climate, moisture, nutrients, and pests and diseases.

Various factors affecting the growth and yield of crops are temperature, light intensity, carbon dioxide concentration in the air, plant light receiving area, etc., to improve crop yield, you can appropriately adjust the temperature, light intensity and carbon dioxide concentration, the first two can be artificial light in the greenhouse, etc., incineration can be used to increase carbon dioxide concentration, as for the plant light receiving area, attention should be paid to keeping an appropriate gap between plants when planting, in order to increase light reception.

1. Climate. Climatic factors such as heat, light, precipitation, and monsoon have a great impact on agricultural location. It is the most important factor affecting the distribution of crops and the development of agriculture.

The growth and development of different animals and plants require different climatic conditions, and the distribution of climatic conditions has obvious regional differences. Therefore, the choice of agriculture in a region should fully consider the local climatic factors.

Moisture: Arid areas with annual precipitation of less than 250 mm cannot develop agriculture unless there is a source of irrigation water.

2. Topography. Different topographic areas are suitable for the development of different types of agriculture. The plain area has a flat terrain and deep soil layer, which is conducive to the realization of agricultural water conservancy and mechanization, and is suitable for the development of farming operations. Mountain farming is inconvenient and not easy to conserve soil and water, but it is suitable for forestry and animal husbandry.

The vertical differentiation of natural conditions in mountainous areas makes the distribution of crops vertical and diversified; If the terrain is complex, it is suitable for diversified operations.

3. Soil. Soil is the material basis for the growth of crops, and different types of soil are suitable for growing different crops. For example, the southeastern hills of China are widely distributed with acidic red soil, which is suitable for planting tea trees.

The fertility of the soil also has a greater impact on agriculture. For example, the Northeast Plain (black soil) and the North China Plain (calcareous soil) have fertile soil, and the yield of rice per unit area is relatively high.

Increase crop yields.

1. Good seeds. High-quality seeds can increase yields, such as Yuan Longping's hybrid rice;

2. Chemical fertilizers. It can eliminate insects and increase production, and relatively little land is needed, but it is very harmful to the environment and will reduce the service life of the land;

3. Machinery. Replacing manual sowing and harvesting with agricultural machinery can save time, increase efficiency, and achieve greater benefits.

4. Irrigation. Scientific irrigation techniques should be determined according to the local climate. For example, Israel is short of water and invented the drip irrigation method.

Soil, land, heat, water, natural disasters, science and technology, and the agricultural base all have an impact on crop yields. The factors that affect crop yields include both natural and socio-economic factors, and we should analyze them according to specific geographic information.

Temperature is the most important factor influencing crop yields. The diurnal range of temperature and light affect the yield and quality of crops, and the high temperature and strong sunshine during the day are conducive to enhancing the photosynthesis of crops and producing more nutrients. The low temperature at night weakens the respiration of crops, reduces the consumption of energy, and is conducive to the accumulation of nutrients. Therefore, in areas with plenty of sunlight and a large temperature difference between day and night, fruit crops are sweet and juicy, and grain effects and other particles are full.

<> factors affecting the growth period of crops include temperature, water, time, agricultural technology, varieties, etc. The growing period of crops refers to the number of days that crops can grow, when the temperature reaches 5-6, the longer the growth period is, the longer the crop accumulates the key to the world, and the better the quality.

The factors influencing the location of agriculture are divided into natural conditions and socio-economic factors.

1. Natural conditions include: climate (heat, light, moisture, temperature difference between day and night), topography, soil;

2. Socio-economic factors include, market demand, transportation, national policies, agricultural production technology, and labor;

3. Climate: Climatic factors such as heat, light, precipitation, and monsoon have a great impact on agriculture. It is the most important factor affecting the distribution of crops and the development of agriculture.

4. Topography: Different topographic areas are suitable for the development of different types of agriculture. The plain area has flat terrain and deep soil layer, which is conducive to the realization of water conservancy and mechanization of agricultural group wheels, and is suitable for the development of farming operations. Mountain farming is inconvenient and not easy to conserve soil and water, but it is suitable for forestry and animal husbandry.

The vertical differentiation of natural conditions in mountainous areas makes the distribution of crops vertical and diversified; If the terrain is complex, it is suitable for diversified operations.

5. Soil: Soil is the material basis for the growth of crops, and different types of soil are suitable for the growth of different crops;

Market demand: Agricultural products must be sold in the market in order to realize their value, therefore, the demand in the market affects the type and scale of agricultural production.

6. Transportation: The choice of agriculture must fully consider the local transportation conditions, art, dairy industry, etc., due to the short shelf life of its products, and the requirements of convenient and fast transportation;

7. Policy: The agriculture of all countries in the world is affected by national policies and interventions;

8. Agricultural production technology: the cultivation of excellent varieties, mechanical and chemical farming, the extensive use of chemical fertilizers and scientific irrigation technology can increase yield, reduce production costs and improve sowing efficiency;

9. Labor force: Labor capacity is also one of the very important agricultural location factors, and there will be no intensive and developed agriculture without sufficient labor.
