Tomatoes are very sensitive to fertilizers. Top dressing is too late too late, too little too much, too concentrated, is not conducive to tomato production. Therefore, rational fertilization is an important measure for the high yield of tomato, and it should master the principles of “one control, two promotion, three sprays, and four avoidancesâ€. A control: Before the colonization of tomatoes to fruit set, the top dressing technique should be controlled and top dressing to see if the seedlings are topped with fertilizers. If the top dressings are too concentrated too early, the stems will have large leaves, dark green leaves, resulting in plant growth, and even Caused by falling flowers. Therefore, in addition to the case of a serious lack of fertilizer in the case of water manure or biochemical organic liquid fertilizer (500 times), generally should be controlled topdressing. Two promotion: Tomato topdressing and harvesting period should be topdressing, promote growth and development, after the first inflorescence and fruit set, and the fruit has walnuts, the plants should be branched, the young fruit should be enlarged, but also continue to flowering results The consumption of nutrients is large. At this time, quick-acting fertilizers should be quickly applied 1-2 times. Generally, 30% of human urine or 5% sulfur-containing compound fertilizer leaching solution should be applied to ensure that the plants do not de-fertilize and promote rapid expansion of young fruit. Must continue to provide nutrients in order to meet the needs of growth, otherwise it will cause late defermentation, and affect the fruit development, resulting in premature plant failure. At this time, the method of diligent chase should be adopted. Usually, a 40% concentration of human excreta or 5% sulfur-containing compound fertilizer leaching solution is applied every 10 days on sunny days. Three sprays: The tomato not only absorbs nutrients from the soil from the roots, but also absorbs mineral nutrients and sugars from the leaves to promote fruit and seed development. Therefore, during the fruit growth period, especially when the continuous raining in the early stage cannot be used for top-dressing, 2-3 sprays should be applied after the leaves are sprayed. The bio-organic liquid fertilizer can be sprayed with 500-300 times of fluid. It can also be used to chelate multiple composite micros. Fertilizer 500 times spray to improve the quality of tomatoes. Four bogey: Tomato top dressing, avoid high-concentration fertilizer, avoid wet soil fertilization, avoid high temperature fertility at noon, avoid too concentrated fertilization, one easy to make the plant leggy, two easy to produce fertilizer damage, wet soil fertilization, caused by falling, Physiological diseases such as defoliation and fruit drop, fertilization under high humidity conditions, due to high soil temperature, large plant evaporation, fertilization, will hinder the normal operation of plants according to the Department, causing plant death. Large wet fertilization and application under high temperature conditions can also cause bacterial wilt to occur. Fertilization should take place in the early morning or early evening.
Lactobacillus johnsonii, a gram-positive bacterium, belongs to phylum Firmicutes, class Bacilli, order Lactobacillales, family Lactobacillaceae, and genus Lactobacillus, which is facultatively anaerobic and sometimes microaerophilic, exhibiting poor growth under aerobic conditions but better growth at reduced oxygen pressure. L. johnsonii was first isolated from human blood, with other primary sources including humans, mice, and pigs (Pridmore et al., 2004; Vazquez-Munoz et al., 2023; Zhang et al., 2019). The health-associated benefits of L. johnsonii are known for its antibacterial properties, inhibiting pathogenic bacteria such as Helicobacter pylori and Staphylococcus aureus (Aiba et al., 2019; Rosignoli et al., 2018). It is also viewed as a substitute for antibiotics in poultry feed due to its ability to suppress Clostridium perfringens (Gervasi et al., 2014). Multiple strains of L. johnsonii contain bile salt hydrolase (BSH) (Boucard et al., 2022), which has been reported to have anti-Giardia lamblia activity and reduce cholesterol (Allain et al., 2018; Zhu et al., 2022). Additionally, L. johnsonii FI9785 can produce extracellular polysaccharides (EPS), which enhances its colonization ability (Mayer et al., 2020). In clinical research, L. johnsonii can serve as an adjuvant to help alleviate type 1 diabetes and allergic rhinitis (Lue et al., 2012; Wang et al., 2022). L. johnsonii exhibits significant antimicrobial potential and has been proven to be effective in livestock farming as a substitute for antibiotics.
