Spring is the best time to introduce seedlings. Xinjiang enters spring and a large number of seedlings are on the market. Some are local or transported from other places. So what should I pay attention to when buying seedlings? A fruit and vegetable company in Shihezi and Zhao signed the "Apple Seedling Substitute Breeding Contract". The seedlings were provided by Zhao, and the actual number of plants planted was 828,826 plants confirmed by both parties. The seedlings involved were pulled from the mainland and stored in a cold storage. When they were out of the warehouse, the seedlings were found to have dry branches and mildew roots. In order to find out the losses, the Fruit and Vegetable Company commissioned Xinjiang Zhenguanda Agricultural Technology Co., Ltd. to apply for agricultural technology appraisal.
After accepting the commission, the company assigned appraisers Zhao Guirong and Gao Shengliang to form an appraisal team to conduct on-site inspection and investigation of the plot involved: the average row spacing of seedlings planted in the appraisal plot was 50cm, and the plant spacing was about 20cm. The mortality rate of seedlings in the north of the land is higher than that in the south (close to the road). After random multi-point sampling survey, a total of 2400 seedlings were investigated, of which the survival rate of seedlings (grafted seedlings) accounted for 64.92%, the survival rate of rootstocks accounted for 11.63%, and the mortality rate of seedlings reached 23.45%.
Zhao Guirong, a senior agronomist of the unit, said: Analysis of the situation learned through on-site inspection and investigation: the failure to irrigate (supply) water in time after seedlings were planted in spring, which affected the normal growth of newly planted seedlings and caused some seedlings to die. In addition, the seedlings involved were pulled from the mainland and stored in the fresh-keeping warehouse. According to the "Seed Law of the People's Republic of China", the "two certificates and one sign" must be held in the process of leaving the nursery, transfer and use of forest seedlings, that is, "seedling inspection and verification", "seedling quarantine certificate", and "seedling origin label". In order to better guarantee the quality of seedlings, and effectively prevent the spread of dangerous pests and weeds. The plaintiff of the seedlings involved in the case failed to provide relevant certificates, and in addition to the transportation and storage process, it cannot guarantee that the seedlings will have no quality problems.
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.
