Latest Key Technical Points for Fertilizer and Water Management of Mangosteen
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 planted in tropical provinces. When we plant mangosteen, fertilizer and water management work is very important. Moreover, after mangosteen is planted, the fertilizer and water management methods for mangosteen must be appropriately changed every year. Now let the editor introduce them to everyone!
1. The first year after planting
Under normal planting conditions, young trees generally survive after planting in summer. At this time, there is high temperature and drought, so a topdressing must be applied in time, and it can be done together with watering. Control the amount well to promote the growth of young mangosteen trees. Then when the rainy season comes, a topdressing of calcium magnesium phosphate fertilizer should be applied in the early stage, by opening holes around the young trees and applying it by the hole application method. After fertilizing, first fill soil back to the roots of the young trees, then mix it thoroughly with the fertilizer and compact it. During the rainy season, fertilizer should be applied about 3 times, mainly with compound fertilizer for balanced fertilization, and soil should be covered 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 young tree stage. Therefore, when topdressing in the second year, the pattern and fertilizers used are not much different from those in the first year. However, the fertilization amount should be appropriately changed. During summer drought, fertilizers should mainly be water-soluble fertilizers, and according to soil fertility and the growth of the young trees, the number of fertilizations should be controlled at about two times. Then during the rainy season, apply about 10 kg of farmyard manure as topdressing, 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 amount of farmyard manure and other fertilizers should also be appropriately increased. Then attention should be paid to water management. When the soil is dry and there is no rain, water should be given in time to prevent soil drought from causing a lack of water for mangosteen growth. However, water should not be excessive either. When there is too much water and the rainy season is encountered, drainage work should also be done well to prevent waterlogging from seriously affecting the respiration of mangosteen roots and reducing yield.
4. Four years after planting
Four years after planting, mangosteen gradually matures. At this time, fertilizers should mainly be farmyard manure and compound fertilizer. Ensure sufficient nutrition and 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 four years 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, related work should also be done well in the fourth year and thereafter. Create a good growing environment for mangosteen.
The above is a brief introduction to fertilizer and water management of mangosteen. 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 much attention! That is all for today's introduction.
