不少于三百字植物化学保护摘要并翻译成英文

植物化学保护是一种新兴的农业技术，它利用植物自身的化学物质来保护自己免受病虫害的侵害。这种方法不仅可以减少农药的使用量，降低环境污染，还可以改善农产品的质量和安全性。

植物化学保护的核心是利用植物自身的化学物质来抵御病虫害。这些化学物质包括植物生长素、植物激素、生物碱、酚类、黄酮类、甾醇类、挥发性油等，它们可以影响病虫害的生长、繁殖、进食、寄生或危害能力，从而保护植物不受侵害。

植物化学保护的应用包括两个方面，一是利用植物自身的化学物质来保护植物，例如利用黄酮类物质来抵御真菌病害的侵害；二是利用人工合成的化学物质来模拟植物自身的化学防御机制，例如利用合成的植物生长调节剂来抑制害虫的生长和繁殖。

目前，植物化学保护已经在一些农作物的生产中得到了应用，例如水稻、小麦、玉米、棉花、蔬菜等。通过植物化学保护，不仅可以提高农作物的产量和品质，还可以降低农药的使用量，减少环境污染，从而实现可持续农业的发展。

总之，植物化学保护是一种创新的、环保的农业技术，具有广阔的应用前景和重要的意义。

Plant chemical protection is an emerging agricultural technology that uses the chemical substances of plants themselves to protect themselves from damage by pests and diseases. This method not only reduces the amount of pesticides used, but also improves the quality and safety of agricultural products.

The core of plant chemical protection is to use the chemical substances of plants themselves to resist pests and diseases. These chemical substances include plant growth hormones, plant hormones, alkaloids, phenols, flavonoids, sterols, volatile oils, etc., which can affect the growth, reproduction, feeding, parasitic or harmful ability of pests and diseases, thereby protecting plants from invasion.

The application of plant chemical protection includes two aspects: one is to use the chemical substances of plants themselves to protect plants, such as using flavonoids to resist fungal diseases; the other is to use artificially synthesized chemical substances to simulate the plant's own chemical defense mechanism, such as using synthetic plant growth regulators to inhibit the growth and reproduction of pests.

At present, plant chemical protection has been applied in the production of some crops, such as rice, wheat, corn, cotton, vegetables, etc. Through plant chemical protection, not only can the yield and quality of crops be improved, but also the amount of pesticides can be reduced, and environmental pollution can be reduced, thereby achieving the development of sustainable agriculture.

In summary, plant chemical protection is an innovative and environmentally friendly agricultural technology with broad application prospects and important significance
