The changes made when using any type of cover on fruit trees, whether nets or covers, can be positive or negative. Everything will depend on the technical qualities of the cover chosen and the subsequent management of the crop and the cover.
AGRALIA In its permanent search for new and innovative technologies that help to continuously improve the productive management of the fruit business, it develops AGRICOVER©.
AGRICOVER© achieves a light transmission percentage of 86-90% between 600-800 mm, which are the fundamental wavelengths for photosynthesis. The polymers that compose it prevent the rapid loss of light transmission, losing a maximum of between 1.5 and 2% annually. In addition, the light diffusion produced by AGRICOVER© transforms the light that reaches the foliage directly into diffuse light. This allows illuminating areas of the plants that would otherwise be in the shade, increasing the efficiency of net photosynthesis, providing uniformity in plant development and fruit ripening. The high level of diffuse light produced by AGRICOVER© It also allows for savings in water and fertilizers of 25-30% by reducing evapotranspiration.
Light diffusion, and therefore radiation diffusion, prevents excessive heating of the upper part of the plant because it evenly distributes the radiation, improving the firmness, colour and sugar content of the fruits.
AGRICOVER© It has an average blocking of 86.2% of long-wave IR and this considerably reduces the effect of thermal inversion, keeping the air mass under the cover at a higher temperature than the surrounding air, providing an anti-frost effect by blocking the loss of long-wave infrared radiation. This accelerates the plant development processes and therefore the precocity, bringing forward the harvest by between 4 and 10 days depending on the geographical area and the variety.
AGRICOVER© It is a fabric laminated on both sides. This feature prevents dust and moisture from penetrating between the fabric strips, which causes loss of transmittance. This allows the cover to have more light passing through for a longer time.
In a research carried out at the UPC (Polytechnic University of Catalonia) with a computer program that reproduces a virtual wind tunnel, it has been shown that AGRICOVER© It can withstand wind gusts of up to 120 km/hr so it can be used in particularly windy areas.
AGRALIA continues to research and patent new solutions to the agro-climatic problems faced by modern farmers and, together with its agricultural engineering team, analyzes the needs of crops and offers the ideal material, both technically and economically. AGRICOVER© It is also used in fruit trees such as grapes, apples, plums and fruits in general. This is how it develops AGRICOVER U© which is very light and its resistance is several times greater than that of low-density polyethylene films. It is protected against UV radiation from the sun and agrochemical protectors, with additives formulated and supplied by prestigious European manufacturers.
In short, AGRICOVER© It is the ideal solution to protect cherry and other fruit crops, protecting them from rain, frost, hail, and avoiding cracking problems. With the correct management and with the agrotechnical advice of AGRALIA It is possible to achieve better plant development by improving the firmness of the fruit and the sugar content, ensuring greater profitability of your crops.
