The present application relates to the technical field of plant nutrient solution, in particular to a plant nutrient solution for potted landscape flowers and a preparation process thereof.The preparation process of the plant nutrient solution comprises the following steps: preparing an oxidized alginate-lysine compound; preparing a methylthiophanate sodium salt derivative; preparing a silver ion alkaloid compound; and preparing the plant nutrient solution for potted landscape flowers.The present application oxidizes the alginate to form an oxidized alginate through periodate, which exposes a large number of highly active aldehyde groups on the molecular chain, and these aldehyde groups further undergo reductive amination reaction with the amino groups of lysine to form an oxidized alginate-lysine compound through covalent bonding, and the metal cation trace elements in the nutrient solution are stably carried through chelation to form an organic small molecule chelate, which avoids being fixed by soil, is more easily absorbed by the root system and is efficiently transported in the plant body, realizes sustained stimulation and nutrition supply, and thus can play a biological regulation function of promoting growth and improving stress resistance for a long time and in a slow-release manner.

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.

This invention discloses a method for enhancing cucumber resistance to Fusarium wilt by driving the accumulation of rhizosphere bacteria using Trichoderma echinococcus FJ035, belonging to the field of plant disease biological control technology. The method involves applying Trichoderma echinococcus FJ035, Nitro-reducing Pseudomonas 22, and Bacillus vesicularis 33 to the cucumber rhizosphere via root irrigation. This method offers stable efficacy, is environmentally friendly, and can replace or reduce the use of chemical pesticides. The control efficacy in potted plants reaches 77.97%, and in the field, it reaches 68.42%, comparable to the efficacy of commonly used chemical pesticides such as hymexazol and thiophanate-methyl, demonstrating promising prospects for industrial application.
