The invention discloses an application of Cu-NPs as a bacteriostatic agent of alternaria solani. The concentration of the Cu-NPs is 100 g * mL <-1 >. The Cu-NPs is low in production cost, safe and simple in application and operation method, experiments prove that the Cu-NPs have broad-spectrum inhibitory activity on plant pathogenic fungi, the antibacterial effect of the Cu-NPs at the concentration of 100 g.mL <-1 > is optimal, and the antibacterial effect of the Cu-NPs is superior to that of broad-spectrum bactericide thiophanate methyl. The antibacterial rate of the Cu-NPs solution with the concentration of 100 g.mL <-1 > on tomato early blight pathogenic bacteria alternaria solani reaches 85%.

The invention relates to the technical field of plant nutrient solutions, in particular to a plant nutrient solution for potted flowers and a preparation process of the plant nutrient solution. The preparation process of the plant nutrient solution comprises the following steps: preparing an oxidized alginic acid-lysine compound; preparing a thiophanate methyl sodium salt derivative; preparing a silver ion alkaloid compound; and preparing the plant nutrient solution for potted flowers. Alginic acid is subjected to oxidation ring opening through periodate to form oxidized alginic acid, a large number of high-activity aldehyde groups are exposed on a molecular chain of the oxidized alginic acid, the aldehyde groups and amino groups of lysine are subjected to a reductive amination reaction, and the oxidized alginic acid-lysine compound is formed through covalent bonding. Metal cation trace elements in the nutrient solution are stably carried through chelation to form small organic molecule chelates which are prevented from being fixed by soil, so that the small organic molecule chelates are more easily absorbed by root systems and efficiently transported in plant bodies, and continuous stimulation and nutrient supply are realized, so that the biological regulation functions of promoting growth and improving stress resistance can be played in a long-time and slow-release manner.

The invention relates to the technical field of tobacco disease prevention and control methods, in particular to a tobacco floating seedling disease prevention and control method. Comprising the following steps: adding a mixed disinfectant of 20-30 g / m < 3 > of trichloroisocyanuric acid, 20-30 g / m < 3 > of thiophanate methyl and 5-8 g / m < 3 > of moroxydine hydrochloride into each floating nursery pond; in the floating seedling raising process, terahertz wave treatment is continuously applied to the floating seedling raising pond; a small amount of disinfectant combination with a specific proportion is added into the floating seedling raising pond, terahertz wave treatment is applied to the floating seedling raising pond, fumigation and other disinfection means are matched, the disease infection rate of the tobacco seedlings can be completely controlled to be 0%, and tobacco seedling growth hindering caused by phytotoxicity is avoided.
