First, choose good breeds. There are many kinds and varieties of citrus that can be grown in China. We must choose the best variety based on the local ecological conditions and market demand. To deal with seedlings, including the removal of curved root seedlings, unqualified seedlings, short cut too long roots, injured roots. For seedlings that have been transported long distances, the roots of the seedlings should be soaked in clean water for about 2 hours before transplanting, and then they should be marked with mud. Second, suitable ecological conditions. Suitable ecological conditions include suitable climatic conditions and suitable soil conditions. Citrus is a tropical, subtropical evergreen tree, and the heat conditions required for growth are relatively high. Even the most cold-resistant cultivar, Wenzhou Tangan, requires an annual average temperature higher than 15°C, and an extreme winter temperature higher than -7°C. Third, adopt formula fertilization. Formula fertilization refers to the determination of various soil nutrient elements available for citrus fruit trees, combined with the needs of various growth and development stages of citrus trees, proportionately combining various required fertilizers, and based on the percentage of fertilizers that can be absorbed and utilized in soil. A scientific fertilization method to determine the amount of fertilizer applied. Adopting soil testing and formula fertilization technology can achieve the purposes of increasing fertilizer production, improving fertilizer efficiency, improving soil fertility, and ecological protection. Fourth, transplant science caution. Transplanting should be as vertical and horizontal as possible, conducive to orchard management and ventilation. Seedlings should not be planted too deep or too shallow, and should be consistent with the nursery. Generally, the interface of the seedlings is 3 to 5 centimeters above the surface. When transplanting, the root system will be neat and the root system must not be in direct contact with the applied base fertilizer. When seedlings are transplanted, the soil should be compacted, the roots should be poured, and the dry areas must be covered with water. Fifth, planting logistic fertilizer water. About half a month after planting seedlings can survive, if the soil is dry, watering once every 1 to 2 days, can only be topdressing after survival, should be diluted thin liquid fertilizer to promote root and shoot growth. Remember to solve the grafting tape in due course.
Laboratory Consumables Deep Well Plates is used for culturing cells or bacteria, with 6 wells, 12 wells, 24 wells, 48 wells and 96 wells. Similar to clear microplates, but for a very different purpose. Laboratory Microplates of medium to the wells of the culture plate, and then carry out cell culture in a suitable environment. Generally, the culture plate has a flat bottom, which is suitable for the suspension culture of cells and tissues, and also has aU-bottom microplate and a Round deep hole plate. After surface modification treatment, it can have cell adherent culture and growth characteristics.
