Ozonation of irrigation water is a promising technology that improves the efficiency systems. However, it necessary to investigate potential adverse effects continuous application this on pastures, particularly Mombaça grass (Panicum maximum cv. Mombaça), ensure its benefits are not outweighed by negative impacts. This study aimed evaluate impact ozonated production under different fertilization management practices. The experiment was conducted in controlled environment using 4.5 L pots, following completely randomized design with five replications. experimental setup employed factorial arrangement, involving two sources (with and without ozonation) managements N K2O), resulting 20 units. A 60-day uniformity cycle three 30-day cycles were performed, assessing consumption as well morphogenic agronomic characteristics grass. Fertilization K2O increased improved grass, promoting greater development growth line traits. Regardless fertilization, ozonation did cause harm biomass yield. Therefore, technique ozonating can be used cultivation

With the widespread application of ozone technology in agricultural plant protection, developing an ozonated water atomizer that integrates efficient mixing and precise spraying has been recognized as a significant challenge. Swirling flow is considered method to enhance hydrodynamics mass transfer gas–liquid mixing. This study innovatively combines axial nozzle with swirling chamber, utilizing negative pressure generated by high-speed central airflow at throat driving force for initial atomization, completing preliminary atomization before formation mist, thereby improving contact efficiency. Through numerical simulations, impact geometric parameters key locations on internal was analyzed. The optimized inlet diameter found be 9 mm, length 3 mm self-priming hole 1.5 mm. Experimental results droplet size concentration verified optimal 0.6 MPa, up 3.73 mg·L−1 average 102 µm, evenly distributed, could distance 40 cm from target. work provides technological framework advancing precision ozone-based aligning global efforts reduce agrochemical footprints through innovative systems. It offers theoretical guidance data support development design high-efficiency atomizers applications, aiming minimize use chemicals promote growth green protection technologies.

Mustard is an important cash crop of the genus Brassica in family Cruciferae. Low temperature environmental factor limiting growth mustard. In this study, 65 leafy mustard cultivars were used as experimental materials, 25 °C was set control temperature, and 5 chilling stress to investigated physiological response chlorophyll (Chl) content, soluble sugar (SS) proline (Pro) antioxidant enzyme activity, malondialdehyde (MDA) fluorescence injury. The tolerance coefficients each individual index measured correlation analysis, principal component analysis (PCA), membership function method, cluster applied evaluate tolerance. a comprehensive most chilling-tolerant cultivar SJTKJ, least DX. Stepwise regression establish mathematical model for evaluating mustard, four identification indices, including Fv/Fm, ΦPSII, POD Rfd screened. This study provides reference evaluation breeding new cultivars.
