Nursery Shade temperature and humidity control

Nursery Shade temperature and humidity control

Nursery Shade

Shade for nurseries is essential to protect delicate plants from direct sunlight. Protection from heat and sun is especially require when potted plants rest on pavement rather than soil. In this case, temperatures can easily rise higher compared to those at ground level. Therefore, it’s appropriate to resort to temporary or permanent shading solutions. Nursery shade mesh is easy to place where need, and with an opening and closing system, its application can be control and regulate.

Nursery Cultivation with Nursery Shade

In the nursery, or in some protective structure, plants are usually cultivate for commercial purposes. Nurseries are generally specialize in certain plant varieties. Some focus on fruit trees (fruit nurseries), others on vegetables (vegetable nurseries), and yet others on ornamental plants (ornamental nurseries). The production of ornamental plants begins with the “adoption” of young seedlings grown in pots. Once in the nursery and transplanted, their “gestation” lasts approximately one year.

During this period, seedlings grow in tunnels or structures covered with shade mesh. This is follow by transplantation in open fields. Plants are usually grow using containers, making them easy to sell and transport. Generally, nursery crop dimensions are smaller compare to those grow in open fields. Nursery shade mesh reduces water loss due to evaporation and helps decrease root temperatures and transpiration.

Environmental Factor Control in a Nursery. Shading as a Good Complement to Reduce Excessive Radiation in Nurseries.

Control of environmental parameters is very important in a nursery. Temperature, light, and humidity must be regulate, taking into account the requirements of the species and their development phase.

Ideal Temperature for Common Vegetables

The most suitable temperatures for rapid and uniform germination depend on each plant. For example, lettuce thrives at around 18°C, tomatoes at 22-24°C, and peppers and eggplants at up to 26-27°C.

Other Examples

Beans: 18-30°C

Cucumber: 20-25°C

Melon: 25-30°C

Zucchini: 25-35°C

If the temperature exceeds these parameters, it can hinder proper vegetative development. Thanks to OBAMALLA® nursery shade mesh, it’s possible to control temperature, relative humidity, and light, both its intensity and wavelength. Many bacterial diseases are reduce thanks to proper temperature and humidity management. For example, tomato seeds can suffer from pathogens, especially bacteria. Bacterial canker in tomatoes is also a serious problem in nurseries as it easily spreads from plant to plant during pruning operations.

Plant Stress

Among the environmental conditions that can cause stress are high temperatures and excessive light. In addition to high temperatures, there is a shortage of water, adding to water stress. Stress affects photosynthesis, protein synthesis, and cell expansion. In fact, the reduction of leaf area is an adaptive response to water deficit. It can manifest in leaves when transpiration is insufficient or when stomata are partially or completely closed, and irradiance is high. Special care must be take to protect germinating seeds when the substrate is heat by the sun. Fruits can also suffer due to reduced transpirational capacity and inhibited photosynthesis.

Signs of High Temperatures and Plant Distress:

-Curled leaves;

-Golden tips and edges;

-Dropping of older leaves;

-Rapid fading of flowers;

-Stunted growth.

Humidity Control in the Nursery

Indoor air humidity in a greenhouse is crucial for plant life. It affects growth, transpiration, flower fertilization, and is also a factor in disease development. Indeed, when humidity is excessive, evaporation becomes more difficult. If it’s scarce, transpiration increases until it hinders photosynthesis. Humidity, with the same amount of water in the environment, changes with temperature, so you must check both parameters to achieve the best conditions. Excessive humidity is corrected by ventilation, raising the temperature, and avoiding wet soils. Conversely, it can be increase, if scarce, with irrigation or water spraying.

Examples of Optimal Humidity According to Vegetable Type

  • Tomato, pepper, eggplant: 50-60%
  • Melon: 60-70%
  • Watermelon: 65-75%
  • Strawberries: 70-80%
  • Cucumbers: 70-90%

High temperatures cause overheating of the air. This heat overload must be removed by allowing the temperature to approach the optimal temperatures indicated. An economical system is the installation of nursery shade mesh, which also allows for good natural ventilation to help regulate humidity.

Plant Transpiration Mechanism

Transpiration is a defense mechanism against excessive heating. It mainly occurs through stomata, which are found either in leaves or young stems, and lenticels. Transpiration is influenced by several factors, one of the most important being temperature. In fact, the rate of water evaporation doubles for every 10°C increase in temperature. Thus, transpiration serves a protective function against external environmental factors.

Of course, air humidity also influences the phenomenon because if it’s saturated with water vapor, additional evaporation slows down. Stomatal cells are sensitive to light and temperature. Generally, most water is transpired during the day, while the nighttime portion covers only approximately 3% of the total. Whenever abnormalities occur in environmental conditions, especially in terms of light and temperature, the value of transpiration also fluctuates considerably.

Nursery Shade Mesh

Thanks to shade mesh, ideal for creating tunnels or half-shade covers, regular shading is obtained, optimizing crop performance. Obamalla offers seasonal protection for many types of crops (flowers, plants, vegetables).
