According to weather forecasts by the Meteorological Department, the average temperature this winter is slightly lower than usual. In order to effectively prevent the effects of freezing damage and weed damage, the following measures must be taken:
Topdressing and antifreeze For fields with poor soil quality, insufficient base fertilizer application or late sowing date, use the favorable opportunity of high soil moisture to apply seedling fertilizer in time, especially for fields with no-tillage direct broadcast, to prevent freezing damage and soil damage. Apply quick-acting fertilizer in time to promote the growth of barley, generally 3-5 kg ​​of urea per mu is appropriate.
Chemical control and prevention of land plots with prosperous growth or high density can choose chemical control and prevention. The specific method is to reduce the amount of paclobutrazol and mix with mepiperium, or use the compounding agent of paclobutrazol and mepiperium, polyazole·mepiperium, which can prevent the wheat seedling population from increasing too much.
Timely chemical weeding For fields that have not been removed a year ago, chemical weeding should be carried out before jointing. For herbicide spraying, you should choose fine weather. For the control of gramineous weeds in barley fields, it is recommended to use 5% pinoxaden (Aixiu); for broad-leaved weeds, use 20% fluroxypyr (totalon). ) 70ml/mu stem and leaf spray control.
For wheat fields with weak growth or freezing damage, the spring topdressing time should be appropriately advanced for the turning-green jointing fertilizer and booting fertilizer topdressing. The turning-green jointing fertilizer shall be topdressed with about 7.5 kg of urea per mu. For wheat fields with high fertility, sufficient base fertilizer, and vigorous growth, it is necessary to apply less or no nitrogen fertilizer to prevent late maturity and lodging in the later stage. Topdressing 3 kg of phosphorus pentoxide and 2.5 kg of potassium oxide per acre can be used during the returning green jointing period. The stalks prevent falling, promote ripeness and improve quality. Booting fertilizer is applied according to the seedling condition. For fields with less than 250,000 ears per mu, 3~5 kg of urea per mu can be applied at the beginning of earing. In addition, according to the occurrence of diseases and pests in the field, timely control of barley aphids, sheath blight, powdery mildew, head blight and other pests and diseases should be carried out.

Herbal Extracts are concentrated forms of plant-derived compounds that are used for various medicinal and therapeutic purposes. These extracts are obtained by processing plants and isolating the active ingredients responsible for their beneficial effects.
There are several ways to classify herbal extracts based on their properties and applications. One common classification is based on the solvent used for extraction. Solvents like water, alcohol, and oil are commonly used to extract different types of compounds from plants. Water extracts, also known as herbal teas or infusions, are made by steeping herbs in hot water. These extracts are often used for their mild and soothing effects. Alcohol extracts, known as tinctures, are made by soaking herbs in alcohol or a mixture of alcohol and water. Tinctures are highly concentrated and are known for their long shelf life and fast-acting properties. Oil extracts, also called essential oils, are obtained through processes like steam distillation or cold-pressing. These extracts are highly concentrated and are used for their aromatic and therapeutic properties.
Another classification of herbal extracts is based on the part of the plant used for extraction. Some extracts are derived from the leaves, flowers, or stems of the plants, while others are obtained from the roots, bark, or seeds. Each part of the plant contains different types and concentrations of active compounds, which determine their specific effects. For example, leaf extracts are often used for their antioxidant and anti-inflammatory properties, while root extracts are known for their immune-boosting and energy-enhancing effects.
