Factors affecting crop growth and yield

1. Climate

Climate factors such as heat, light, precipitation, and monsoon have a great impact on agricultural location. It is the most important factor affecting crop distribution and agricultural development. 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 local climatic factors.

Moisture: Arid areas with annual precipitation less than 250 mm generally cannot develop agriculture except for irrigation water sources.

2. Terrain

Different terrain areas are suitable for the development of different types of agriculture. Plain areas have flat terrain and deep soil layers, which are conducive to the realization of agricultural water conservancy and mechanization, and are suitable for the development of farming operations; mountainous areas are inconvenient to farm and difficult to conserve soil and water, but are suitable for the development of forestry and animal husbandry. The vertical differentiation of natural conditions in mountainous areas makes the distribution of crops vertical and diversified; complex terrain is suitable for diversified operations.

3. Soil

Soil is the material basis for the growth of crops. Different types of soil are suitable for growing different crops. For example, acidic red soil is widely distributed in the hills of southeastern my country, which is suitable for planting tea trees. The fertility of the soil also has a greater impact on agriculture. For example, the soil in Northeast my country Plain (black soil) and North China Plain (calciferous soil) is fertile, and the rice yield per unit area is high.

Increase crop yield

1. Improved seeds

High-quality seeds can increase yield, such as Yuan Longping’s hybrid rice;

2. Chemical fertilizers

It can eliminate insects and increase production, and requires relatively less land, but it is very harmful to the environment and will reduce the service life of the land;

3. Machinery

Using agricultural machinery to replace manual sowing and harvesting can save time, improve efficiency, and obtain greater benefits.

4. Irrigation

Scientific irrigation technology should be determined according to the local climate. For example: Israel was short of water and invented the drip irrigation method.
