How to apply fertilizer to autumn mango

Autumn mango is a mango that blossoms and bears fruit in autumn. The autumn mango varieties planted in various parts of Maoming include cinnamon fragrant mango, purple flower mango and string mango. The quality and flavor of cinnamon mango is good, and the middle and upper string mango genus is suitable for local cultivation with stable yield and high yield. The key to make Qiu Grain in Beard well lies in scientific fertilization management. That is to say, different fertilization management measures must be taken according to the difference between young trees and fruit trees. The main purpose of fertilization management of young trees is to promote the rapid growth of new shoots and expand the crown to lay a good foundation for early fruiting and high yield. The principle of fertilization is that the application of light fertilizer increases gradually from light to strong after repeated application before application. In the first year after planting, the plant was fertilized once a month from the restoration of growth. Each plant was fertilized with 2.5 kilograms of fecal water and 0.25 kilograms of urea. After the second year, on the basis of a little budding for 15 days, the amount of fertilizer should be more than half a load of manure water and 0.5 kg urea per plant. After smoking, topdressing should be carried out according to the leaf color. The main purpose of fertilization of fruiting trees is to promote the flowering and fruiting of plants in the same year and strive for strong autumn shoots to lay the foundation for stable and high yield in the coming year. Focus on attacking a little fertilizer, strong flower fertilizer, strong fruit fertilizer and do a good job of flower and fruit protection. 1. The attack is a little fat. It is necessary to apply fertilizer according to the amount of mango fruit in order to restore the tree potential as soon as possible and extract the strong autumn as the fruiting mother branch in the coming year. Therefore, the re-application of slightly fertilizer should account for 60% of the annual fertilizer application, mainly organic fertilizer combined with quick-acting chemical fertilizer. According to the amount of fruit per plant, 2 kilograms of soil and miscellaneous fertilizer should be applied, 2 kilograms of peanut bran, 2.5 kilograms of urea, 0.5 kilograms of superphosphate, 1 kilogram of superphosphate, 0.5 kilograms of potassium chloride. Fertilization should be applied from August to September after harvest of early-maturing seeds and before harvest of late-maturing seeds. two。 Strong flowers are fat. The available nitrogen fertilizer should be applied 15-20 days before flowering and properly combined with phosphorus and potassium fertilizer. Each tree was applied urea 1 kg peanut bran 1 kg 1.5 kg calcium superphosphate 0.5 kg potassium chloride 0.25 kg in February and March of next year. 3. Strong fruit is fat. It should be applied in the early stage of fruit expansion after flowering, mainly with available nitrogen combined with phosphorus and potassium fertilizer before physiological fruit drop from May to June. 0.5 kg of urea per plant, 0.25 kg of potassium fertilizer and 2 piculs of manure should be combined with extra-root fertilization in order to make the fruit thick and strong. 4. Protect flowers and fruits. In order to protect flowers and fruits well, we should take the following three measures: (1) remove the inflorescence. The inflorescence should be removed when the inflorescence is less than 7 cm. If the single embryo variety can be removed during flowering because of its strong germination ability, it can also germinate inflorescence from axillary buds. Inflorescences should be removed once or twice according to weather conditions. (2) spraying hormone. Spraying paclobutrazol 500 ppm or 1500 ppm B9 twice every 20-30 days from the first ten days of November can slightly delay the germination of flower buds and leaf buds. (3) Disease and pest control should be done in time in order to ensure the normal growth of branches and the fullness of fruit. In addition, timely pruning and pruning of disease and insect branches, withered branches and weak branches to remove the top peripheral dense branches to form ventilation and reduce the occurrence of diseases and insect pests is beneficial to achieve stable yield and bumper harvest.
