Análisis de extracto de savia para determinar el estado nutricional del cultivo de rosa

Abstract

The present research work seeks to determine the nutritional levels of the rose bush by means of rapid measurement equipment in situ, in order to recommend and evaluate the efficiency of fertigation. For the measurements of the nutrient content in the sap, vegetative stems were used in the rice state, monitoring the collection temperature of the samples at 15 °C, 10 stems were cut for each repetition, defoliating and measuring 10 cm of the stem, they were crushed. the pieces of stems and the sap was extracted by means of a syringe, these samples were placed in the Horiba sensors for analysis. The nutrient solutions of the soil were extracted from the suction lysimeter or sucker, by means of an emptying of the sucker and they were placed in the horiba sensors for their respective analysis. It was found that the higher the temperature and radiation, the higher the absorption of the elements at the sap level, likewise, the lower these parameters are, the lower the absorption at the sap level. In the case of the sucker analysis, the higher the temperature, the nutrient content in the solution will be higher, because evapotranspiration allows a greater flow of masses and movement of the elements contained in the soil, otherwise it occurs when the temperature and radiation are less. Therefore, it is determined that the use of the Horiba meters allows a quick and efficient assessment of the absorption of nutrients in the cultivation of the rose.
