Horticultural Shade

Horticultural Shade

Horticultural shade is widely use for horticultural production in warm regions, especially where high radiation and temperatures necessitate adequate crop protection with horticultural shade.

Shade netting is ideal for areas with high temperatures.

Vegetables such as tomatoes, peppers, and eggplants require relatively high temperatures to achieve their typical color intensity. For example, the red color of ripe tomatoes is attribute to lycopene, a carotenoid synthesized and stored in chromoplasts. However, excessive temperatures can cause damage and harm the harvest.

Effects of high temperatures on crops and horticultural shade

High temperatures influence the photosynthesis process by causing stomatal closure and increasing respiration rate, resulting in reduced production and yield. Air temperatures not only have negative effects on plant growth and yield but also affect developmental processes in different stages. High temperatures lead to “heat delay,” delaying flowering onset. Additionally, pollination, fruit formation, and quality can be altered, and thermal stress from high temperatures significantly reduces harvest weight.

Problems caused by direct sunlight on crops with horticultural shade

The intensity of radiation and high temperature increase the incidence of blossom end rot in tomatoes, peppers, and eggplants. The flavor and nutrients of fruits and vegetables are also influence by temperature. High temperatures have been proven to negatively influence taste, color, and lycopene content. High temperatures also lead to inadequate sugar accumulation in melons, cherry tomatoes, and watermelons. Pre-harvest temperatures particularly affect harvest quality and post-harvest deterioration (storage life).

Humidity under horticultural shade: its influence on plant growth and product quality

Humidity is a significant environmental factor influencing plant water status, particularly affecting processes associated with transpiration. With very high external temperatures in arid regions, the risk of drought stress could be significant, especially for crops with high air humidity requirements such as cucumbers. Managing humidity serves two main purposes: maintaining crop transpiration within limits and preventing condensation on crops. Excessively high or low transpiration rates can cause calcium deficiencies, turgor loss, partial stomatal closure, among other issues. Condensation increases the incidence of disease-causing organisms like botrytis.

Inadequate humidity can cause skin cracking due to stress. Shading allows for more controlled humidity management.

Other factors to consider

Ventilation

Horticultural shade with plastic mesh allows for good natural ventilation, reducing physical damage to foliage and fruit. Indeed, an important effect of agricultural shade is to decrease air speed. Additionally, by reducing gas exchange rates between leaves and their environment, it promotes water conservation. Ventilation helps maintain temperature and humidity within safe and convenient ranges.

How agricultural shade helps reduce water stress

Both water excess and deprivation cause stress in plants. For instance, a typical disorder in tomato fruits is blossom end rot, usually due to water deficit. Conversely, cracking occurs with excess water supply. Furthermore, photosynthesis and transpiration are negatively affected by water stress.

The delicate process of transpiration

Most of the water consumed by plants is use in transpiration, as well as in regulating internal temperature. Plants react to water fluctuations primarily by stomatal closure at night and opening at dawn. Transpiration increases with rising temperature until midday, then decreases significantly due to cooling, resulting from gradual stomatal closure.

With this type of netting you can create a stable place for crops to develop properly.

With inadequate water supply or extreme heat and drought, stomata close much earlier. This phenomenon has negative consequences for gas exchange and CO2 assimilation. Due to reduced CO2 assimilation in leaves, metabolic processes are affected, reducing fruit quality and yield. In fact, due to water stress, plants show changes in morphology, such as reduced leaf area.

How environmental management works

Modifying environmental management can significantly improve water use efficiency. Techniques including horticultural shading prevent water stress in plants. There’s a wide range of approaches in protected cultivation that allows producers in different climatic regions to adopt and adjust preferred technology for specific crops. High-tech greenhouses yield high outputs but also require high initial costs. Alternatively, structures with horticultural shade are much cheaper than greenhouses and feature natural ventilation.

Conclusions

In conclusion, direct sunlight, especially in summer, is particularly damaging. Vegetables produce more with partial shade, ensuring adequate brightness. Woven meshes offer various levels of shade according to climatic needs and crop type. Our polyethylene meshes are specially designed to control light incidence in crops. In addition to reducing stress, horticultural shade prevents burns, especially when fruits are ripe. It also promotes higher humidity and helps reduce the need for irrigation. Next-generation plastic meshes allow air passage and ensure optimal ventilation.
