Why is the location and orientation of the greenhouse important?

Oct

In the field of agriculture and horticulture, greenhouse is an important facility to create an ideal growth environment. Its design and layout are directly related to the yield and quality of crops and the operational efficiency of the greenhouse itself. Therefore, when building a greenhouse, besides paying attention to the key factors such as structural materials, structural quality and crops, the location and orientation of the greenhouse also can not be ignored. These two factors directly affect whether a greenhouse can make full use of natural resources, reduce operating costs, and improve the overall production efficiency.

一、When deciding on the location of the greenhouse, the following matters can be taken into account

1. Solar illuminance

Light is an indispensable energy source for plant growth. The greenhouse shall be located so as to receive maximum direct sunlight. If the greenhouse is blocked by tall buildings, trees or other obstacles, it will seriously affect the light efficiency, and then affect the photosynthesis and growth rate of crops. Although moderate shading can reduce the temperature in greenhouse during hot summer, long-term shading can lead to insufficient sunlight and affect crop growth. At the same time, adjacent trees may also increase the risk of greenhouse damage, especially in severe weather conditions.

2. The wind factor

Wind is another big challenge for greenhouse stability. To build greenhouses on the top of mountains, ridges and other places with strong wind, it is necessary to strengthen the structural stability and consider setting up windproof facilities. While aesthetics and visibility may be a consideration in site selection, ensuring the safety of the greenhouse structure and reducing wind damage are the top priorities.

3. Drainage and soil condition

Greenhouses should be built on high ground with good drainage to avoid root diseases caused by flooding and wet soil. Low-lying areas are prone to water accumulation, which not only affects crop growth, but also may cause damage to the foundation of greenhouse. At the same time, soil quality is also one of the factors to consider, fertile and breathable soil is more conducive to crop growth, mainly considering the characteristics of crops.

4. Evenness of site

A flat site is ideal for greenhouse construction. The slope will not only increase the difficulty of construction, but also may lead to the instability of greenhouse structure and poor drainage. If a greenhouse has to be built on a slope, create a flat foundation by digging or filling.

二、The importance of greenhouse orientation

The direction of greenhouse is not only related to beauty, but also directly affects the light efficiency of crops. Greenhouses facing east-west can maximize the use of sunlight, so that crops can get uniform light throughout the growth cycle, thus promoting photosynthesis and improving yield and quality. In contrast, north-south greenhouses are prone to uneven light exposure of crops, excessive light in some areas, and relatively dark in some areas, affecting the overall growth effect.

In addition, the direction of the greenhouse also needs to take into account the local climatic conditions and crop characteristics. For example, in cold regions, the direction of the greenhouse can be adjusted appropriately to maximize the amount of sunlight in winter and increase the temperature in the greenhouse, while in hot regions, the adverse effects of high temperature in summer on crops can be reduced by adjusting the direction of the greenhouse and setting shading facilities.

To sum up, the location and orientation of the greenhouse are the key factors to ensure its efficient operation and reduce risks. When planning and building a greenhouse, these external factors must be fully considered in order to achieve the best planting effect and economic benefits.
