During the post-harvest period in cherry trees, floral differentiation occurs, which is one of the main physiological processes that will sustain the fruit of the following season. This process corresponds to the period in which the flower buds begin to form reproductive structures that will determine the productivity and quality of the fruit. Therefore, it is essential to prepare for the following season in the post-harvest period.
However, in the central part of our country this process occurs during the month of January, where temperatures tend to be extremely high, generating great thermal and water stress in the plant. This causes the plant to close its stomata and produce less gas exchange and photosynthesis, therefore, less sugar formation.
Currently, there are several tools that help mitigate the stress caused by high temperatures in plants. One of them is sunblocks based on kaolinites or transparent lipoprotectors.
Kannu 95 It is a 95% % kaolinite sunscreen, which allows the plant tissue to be coated, helping to mitigate thermal and water stress, as it allows the leaf temperature to be reduced and stomatal conductance and gas exchange to be maintained.
It should be applied immediately post-harvest at a dose of 25 kg/ha every 15 to 20 days, during the period of highest temperatures.
Sun Clear is a transparent sunscreen formulated from calcium, boron and fatty acids as the main barriers against solar radiation, which helps promote the stability of the cuticle of leaves, flowers and fruits. In addition, as an antioxidant barrier, SUN CLEAR has natural plant oils capable of regenerating and protecting cellular tissues from solar rays (UVB).
It is recommended to make periodic applications every 20 days, 3 L/ha during the post-harvest period.
Additionally, it is advisable to use amino acids and organic matter via irrigation, capable of promoting the plant's tolerance to periods of high abiotic stress, which when used as a joint strategy have more favorable results, both to mitigate water and thermal stress, and to prepare for the following season. Aminochem MO It is a biostimulant of plant origin, a soil bioactivator with a high organic carbon content and 20% of free amino acids, therefore, its application in this period contributes to improving soil conditions and stimulating physiological and metabolic processes of plants, resulting in better vegetative development, better tolerance to stress conditions, given the contribution of specific amino acids and it enhances the accumulation of reserves.
During post-harvest, the second flush of root growth also occurs, which is recommended to be reinforced in case of adverse soil conditions by using rooting agents and calcium via the root system.
Rootchem It is a natural rooting agent, formulated with algae extracts and amino acids, capable of promoting the growth and radical density of plants.
Calciochem Flow: Calcium amendment with a highly concentrated, floable formulation, which helps to improve the conditions of heavy soils by flocculating the clays and providing a nutritional effect in cases of nutritional deficiency.
Subsequently, before the leaves fall, it is essential to apply molybdenum, in order to promote the accumulation of reserves, given the enzymatic role of this element in the assimilation of nitrogen by the plant. Molymax: Foliar fertilizer capable of promoting the formation of structures and storage of reserves prior to entering the recess.
