1. Seed treatment: seed dressing with new high-fat film 600-800 times before sowing, can avoid underground pests and diseases, isolate virus infection, does not affect germination and swelling function, strengthens breathing intensity and improves seed germination rate. 2. Seedling management: reasonable control of temperature during seedling stage, seedlings in 2-3 true leaves, when seedlings have 5-6 true leaves, they can be planted. When planting, try to protect seedling roots. After seedling transplanting Spraying a new high-fat film can effectively prevent the moisture on the ground from evaporating, the moisture of the seedlings is not transpiration, the pests and diseases are isolated, the seedling period is shortened, and the survival rate is improved. 3. How to obtain high-yield and high-quality lettuce, spraying vegetables and strong stems during the vigorous growth period can make the stems of the plants thick, the leaves are thick, the leaves are fresh, the plants are flourishing, and the natural taste is strong. At the same time, it can improve the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual toxicity. 4. Pest control: The main diseases are downy mildew, soft rot, viral disease, dry rot, top burning disease; insect pests mainly include leaf miner, whitefly, aphid, thrips and so on. Most of the lettuce used for leaf lettuce is used for raw food, and pests and diseases should be based on prevention. Spraying targeted drugs with new high-fat membranes to reduce pesticide residues and prevent infection by pathogens. Disclaimer: Some articles on this website are transferred from the Internet.

What is Natural Extracts?
Natural extracts have received attention in several fields due to their wide range of sources and potential multiple uses. They can be used in the pharmaceutical industry as ingredients in medicines or health supplements; In the cosmetic industry, as a functional or active ingredient to improve skin health; In the food industry, as an additive or flavoring agent to increase the nutritional value and taste of food; In addition, they have different applications in the fields of agriculture, environmental protection and scientific research.
Extraction methods include solvent extraction method, ultrasonic extraction method, microwave extraction method, enzyme extraction method, supercritical fluid extraction method and microwave assisted extraction method, etc. The choice of which method usually depends on the nature of the substance to be extracted and the target requirements of the final product. With the development of technology, the extraction process is continuously optimized to improve extraction efficiency, reduce environmental impact and maintain the biological activity of the extract.
