Key Points of Fertilizer and Water Management Techniques for Mangosteen Cultivation
The scientific name of mangosteen is also called manggis, and it is a small tree. Mangosteen has a wide planting area in the tropical provinces of our country, but due to its environmental requirements, it can only be grown in tropical provinces. When we grow mangosteen, fertilizer and water management work is very important. Moreover, after mangosteen is planted, the fertilizer and water management methods must be appropriately changed every year. Now let me introduce it to everyone!
1. The first year after planting
Under normal planting conditions, young trees generally survive after planting in summer. At this time, it is hot and dry, so a topdressing of fertilizer should be applied in time, which can be done together with watering. Control the amount to promote the growth of young mangosteen trees. Then when the rainy season comes, apply calcium magnesium phosphate fertilizer once in the early stage, opening holes around the young trees and applying it by the hole application method. After fertilizing, first fill the soil back to the roots of the young trees, then mix it fully with the fertilizer and compact it. During the rainy season, fertilize about 3 times, mainly with compound fertilizer for balanced fertilization, and cover the soil in time after fertilizing.
2. The second year after planting
In the second year, the mangosteen trees are not yet fully mature and are generally in the late stage of young trees. Therefore, when topdressing in the second year, the pattern and fertilizers are not much different from those in the first year. However, the amount of fertilizer should be appropriately changed. During the summer drought, fertilizers should mainly be water-soluble fertilizers. According to the soil fertility and the growth of the young trees, control the number of fertilizations and keep it at about two times. Then during the rainy season, apply about 10 kg of farmyard manure, combined with an appropriate amount of calcium magnesium phosphate fertilizer. Appropriately increase the amount of ternary compound fertilizer to meet the nutritional needs of mangosteen.
3. The third year after planting
After entering the third year, fertilizers should mainly be nitrogen fertilizers, with the purpose of enhancing the growth capacity of the mangosteen trees. The amount of nitrogen fertilizer per plant should be appropriately increased, and then the number of topdressings should be increased. In the early stage of the rainy season, the amounts of farmyard manure and other fertilizers should also be appropriately increased. Then pay attention to water management. When the soil is dry and there is no rain, water in time to prevent soil drought from causing water shortage for mangosteen growth. However, water should not be too much either. When there is too much water and the rainy season occurs, also pay attention to drainage work to prevent waterlogging from seriously affecting the respiration of the mangosteen roots and reducing yield.
4. After the fourth year of planting
After the fourth year of planting, mangosteen gradually matures, and at this time the fertilizers should mainly be farmyard manure and compound fertilizer. Ensure sufficient nutrition to advance the fruiting period of mangosteen. During this period, the planting soil should be appropriately expanded and the soil improved. Then sufficient farmyard manure should be applied under each mangosteen tree, mainly by trenching and broadcasting. After the fourth year of planting, topdressing should be done at least about three times each year to meet the nutrients needed for mangosteen flowering and fruiting. Then, according to the water management method of the third year, do the related work well in the fourth year and thereafter. Create a good growing environment for mangosteen.
The above is a brief introduction to mangosteen fertilizer and water management. In the planting process, there is not only fertilizer and water management, but also other work. For example, pruning and intertillage are all indispensable work when we plant. So everyone must pay more attention! That is all for today's introduction.
