The effect of Bacillus amyloliquefaciens on crops

The effects of Bacillus amyloliquefaciens on crops are mainly reflected in the following aspects:解淀粉芽孢杆菌对作物的影响主要体现在以下几个方面:

Disease resistance and antibacterial:抗病抗菌:

    Bacillus amyloliquefaciens can secrete various secondary metabolites, inhibit the growth and spore germination of pathogenic bacteria, and effectively prevent and control various plant diseases such as root rot, wilt, anthracnose, etc.解淀粉芽孢杆菌能分泌多种次生代谢物，抑制病原菌生长和孢子萌发，有效防治根腐病、枯萎病、炭疽病等多种植物病害。

By directly acting on the fungal cell biofilm system, the cell wall and membrane structure are disrupted, leading to the leakage of pathogenic bacterial contents or cell rupture and death.通过直接作用于真菌细胞生物膜系统，破坏细胞壁和膜结构，导致致病菌内容物外溢或细胞破裂死亡。

Induced resistance: 诱导阻力:

    Bacillus amyloliquefaciens can induce crops to produce superoxide dismutase (SOD), polyphenol oxidase (PPO), peroxidase (POD), etc., improving crop stress resistance.解淀粉芽孢杆菌可诱导作物产生超氧化物歧化酶(SOD)、多酚氧化酶(PPO)、过氧化物酶(POD)等，提高作物的抗逆性。

The antibacterial protein produced can significantly induce the expression of crop resistance genes, increase enzyme activity related to disease resistance, and enhance crop disease resistance.所产生的抗菌蛋白能显著诱导作物抗病基因的表达，提高抗病相关酶的活性，增强作物抗病能力。

Promote growth: 促进经济增长:

    Bacillus amyloliquefaciens can induce plants to rapidly secrete endogenous auxin, promote rapid rooting of crops, enhance root development ability, and thus promote robust plant growth.解淀粉芽孢杆菌可诱导植物快速分泌内源生长素，促进作物快速生根，增强根系发育能力，从而促进植物健壮生长。

By decomposing insoluble trace elements in the environment, the utilization efficiency of nutrients in crop rhizosphere is improved, while generating biomass to further promote crop growth.通过分解环境中不溶性微量元素，提高作物根际养分利用效率，同时产生生物量，进一步促进作物生长。

Research has shown that Bacillus amyloliquefaciens, as a biological fertilizer, can significantly improve the germination rate of seeds and the growth rate of seedlings.研究表明，解淀粉芽孢杆菌作为一种生物肥料，可以显著提高种子发芽率和幼苗生长速度。

Improving soil and enhancing fertility:改良土壤，提高肥力:

    Bacillus amyloliquefaciens can regulate the activity of phosphatase and urease in soil, increase soluble phosphorus content, reduce soil ammonia volatilization, and improve soil fertility.解淀粉芽孢杆菌可调节土壤磷酸酶和脲酶活性，增加土壤可溶性磷含量，减少土壤氨挥发，提高土壤肥力。

    The secondary metabolites secreted by it can promote the dissolution of insoluble metal elements in the soil, thereby increasing the available nutrients in the soil.其分泌的次生代谢物能促进土壤中不溶性金属元素的溶解，从而增加土壤中的有效养分。

    Bacillus amyloliquefaciens can also improve the microecological balance of crop rhizosphere, activate potential nutrients such as phosphorus and potassium, improve soil structure, and curb soil degradation.解淀粉芽孢杆菌还能改善作物根际微生态平衡，激活磷、钾等潜在养分，改善土壤结构，抑制土壤退化。

    In summary, Bacillus amyloliquefaciens has broad application prospects in agriculture. It can not only improve crop disease resistance and stress resistance, but also promote crop growth, improve soil, and enhance fertility. It is an important biological resource for the sustainable development of modern agriculture.

综上所述，解淀粉芽孢杆菌在农业上具有广阔的应用前景。它不仅可以提高作物的抗病性和抗逆性，还可以促进作物生长，改良土壤，提高肥力。它是现代农业可持续发展的重要生物资源。
