How to apply fertilizer management in autumn mango

Autumn mang is the mango that blooms in autumn. The autumn cultivars cultivated in Maoming City include Cinnamon Mang, Zihua Mang and Chuan Mang. The Cinnamon Mango quality flavor is better. The purple genus M. genus is suitable for local cultivation and stable yield and high yield. The key to planting autumn awns lies in scientific fertilization management. That is according to a certain young trees and tree plus the results taken to distinguish between different manure management practices accordingly. The fertilization management of young trees is mainly to promote the rapid growth of new shoots and expand the canopy to lay a good foundation for early fruiting and high yield. The principle of fertilization is to apply the thin application slightly before the application, and gradually increase the light application from light to thick. The first year after planting, fertilize once a month manure per plant every 2.5 to 5 kg of urea 0.25 kg resume growth from the beginning. From the second year onwards, the 15- day germination based on the slightly-based spurt should be applied to the amount of fertilizer, and the amount of fertilizer should be increased by 0.1 to 0.5 kg per plant . After the pumping, the topdressing should be carried out according to the color of the leaves. The fertilization of the fruit tree is mainly to promote the flowering results of the plant in the same year, and strive to make the autumn shoots strong and strong to lay the foundation for stable production and high yield in the coming year . Focus on the attack of a little fat, strong flower fertilizer, strong fruit fertilizer and do a good job of maintaining flowers and fruits. 1. Attack a little fat. To mango for the amount on the outcome of its fertilizer to restore the vigor out of the strong autumn slightly next year as a result alma mater as soon as possible. Therefore, it is necessary to re-apply 60% of the annual fertilization amount for the application of quick-acting fertilizer. According to the calculation result of 50 kg per plant , the soil should be mixed with 2 kinds of peanut bran 2 ~ 2.5 kg of urea 0.5 ~ 0.75 kg of superphosphate 1 kg of potassium chloride 0.5 kg. Fertilization should be applied from August to September before harvesting fruit in early maturing varieties . 2. Strong flower fertilizer. The application of phosphorus and potassium fertilizer should be based on the quick-acting nitrogen fertilizer 15 to 20 days before flowering . Each plant is given 1 kg of peanut bran 1 ~ 1.5 kg of superphosphate 0.5 kg of potassium chloride 0.25 kg in the second and third months of the year. 3. Strong fruit fertilizer. In the early stage of fruit expansion after Xiehua, the application of fast-acting nitrogen and phosphorus and potassium fertilizer should be applied before physiological fruit drop from May to June . 0.5 kg of urea per 0.25 kg potassium 2 supported manure fertilization should be combined to make the outer root fruit coarse robust. 4. Preserved flowers and fruits. To do a good job of maintaining the quality of flowers and flowers should take the following three measures : (1) remove the inflorescence. To different cultivars typically less than 7 cm Inflorescence when shall pick addition. If the single embryo variety can be removed at the time of flowering due to its strong germination ability, the inflorescence can also be germinated from the axillary bud. The inflorescence should be removed 1 to 2 times depending on the weather . (2) Spray hormones. Available paclobutrazol 500 ppm or 1500 parts per million from early November B9 every 20 to 30 days even spraying a spray 2 can be suppressed brake winter i.e. slightly delayed germination good effect on flower buds, leaf buds are . (3) In the tender period and fruit period, pest control should be done in time to ensure the normal growth of the branches and the fullness and fullness of the fruit. In addition, it should be timely trimmed and cut off, pests and branches, dead branches and weak branches to eliminate the dense branches around the top to form ventilation and ventilation to reduce the occurrence of pests and diseases is beneficial to achieve stable yield and good harvest.
