We select fresh mangosteen, take the full seeds and remove the excess pulp. Mix the seeds with fine sand and scrub them in water for a few minutes. This removes the excess flesh and seed coat. Finally, we put the seeds in potassium permanganate to sterilize them.
We usually use coarse river sand and make a rectangular sand bed of 30-40cm in height and 1.2m in width. In the sand bed, we need to build shade nets with 85% shade.
We usually sow the seeds on a sunny day. The seeds lay flat on the sand surface, pressed and squeezed solid, keeping a spacing of 3-5cm between seeds. Spread 2~3cm thick fine sand on its surface, and then drench it once with permeable water. When the water is slightly dry, add trichlorfon soluble emulsifier dilute spray solution once. This will kill ants and other pests.
Keep the sand bed moist, not too dry or too wet during the breeding period. 20 days or so after a thorough drenching, the seedlings can be transplanted.
We generally set up mangosteen seedbeds in places with easy access to transportation, flat terrain and good irrigation and drainage conditions. The seedling bed is generally long, 20cm deep and 60cm wide. It basically meets the requirements of two seedling bags in a horizontal row. Each horizontal seedbed spacing is 50cm. and build shade net.
Mangosteen prefers acidic or weakly acidic organic-rich nutrient soil. Use coconut bran as organic fertilizer and mix it with sandy loam as nutrient soil. Put it into seedling bags and arrange it neatly in the seedbed.
Before 9:00 a.m. and after 4:00 p.m. We transplant the mangosteen seedlings into the seedling bags. One bag per plant, compacted and drenched with sufficient water.
C、Seedling management of mangosteen
We need to drench them once a day in the morning and once a day in the evening. After 10 days, when the leaves turn green, apply a thin solution of urea in water. Twice a month in summer and autumn, and once a month in winter and spring. After 4 months, increase the nutrient supply. Apply nitrogen, phosphorus and potassium compound fertilizer in the ratio of 15:15:15 and melt it into a 1.5% water soluble fertilizer. We can also buy water-soluble fertilizer directly. At present, the water-soluble fertilizer that is used more in the market is produced by Nagric. Compound fertilizer is applied once a month. The amount of compound fertilizer per acre is 2000 g. Pay attention to weeding on weekdays. When the mangosteen seedlings grow lateral branches, we need to tie them with small branches to fix them, which can prevent typhoons.
During 2.5 to 3 years, when the mangosteen seedlings grow the first pair of lateral branches. We need to tie and fix them with small branches, which can prevent typhoons. In the 4th year after sowing, when it grows to about 80cm, the stem is about 1cm thick and a pair of branches grows, it can be taken out of the soil as a live seedling. We plucked the soil, removed the seedling bowl, boxed it and transplanted it to the planting garden.
E、Planting management of mangosteen
Usually, we make a large hole of 60cm*60cm*60cm as the planting hole of mangosteen. We use 15kg of farm humus and 0.5kg of Sanyuan fertilizer. Then, mix them with soil and fill the holes. The planting time of mangosteen is usually in the afternoon on a cloudy day. We cut off the damaged leaves and put them in to fill them in. Then, we dig the planting hole 20cm deep. Finally, we remove the nutrient bags, backfill with fertilized soil, and make a water tray. Build a shade shelter over the young mangosteen seedlings. Plant about 33 plants per acre. Drench with rooting water. After planting, drench every two days. 15 days later, they will be alive.
F、Young mangosteen management
1、The first year
For young mangosteen trees, we need to cover the ground with 10cm~20cm of hay. And check the shade net for breakage from time to time. Water and fertilizer should be sufficient, usually by irrigation. In the dry season, we need to apply 2 times of urea water solution, the dosage is 3kg per acre. early in the rainy season, open holes on both sides of each tree and apply once 10kg of organic fertilizer mixed with 0.25kg of ternary fertilizer. Finally, mulch the soil. Rotate east and west, north and south in turn.
2、Second to third year
In the second to third year, we need to remove the support sticks of the mangosteen. Moisture management is basically the same as the first year. We need to weed frequently. Fertilization is basically the same, with an appropriate increase in the amount of fertilizer applied. The amount of urea water solution is 4kg per acre.
3、Fourth to sixth year
In the fourth year, we remove the shade netting from the manzanita trees that have grown well. The poorer ones are removed in the fifth year. This way the mangosteen trees can adapt to growing in stronger sunlight. During the rainy season, artificial irrigation is generally not required as long as there is no prolonged drought. In the dry season, irrigation is usually done every 10-15 days. Fertilizers are mainly organic and ternary fertilizers. Fertilizer is applied once at the beginning of the rainy season, about 20kg per year, three times during the rainy season from May to September, with 100g~160g of ternary compound fertilizer per young tree, and once before and after the rainy season, with about 200g per mangosteen tree. At present, the more used water soluble fertilizer in the market comes from Nagric.
G、Management of mangosteen trees
Each mangosteen tree needs a pre-bloom fertilizer before flowering. We apply 30g of potassium chloride compound fertilizer and 120g of ternary fertilizer by furrow application, and irrigate once or twice a month during the flowering period.
The same fertilizer is applied to the young fruits of the mangosteen tree in the same amount as the pre-flowering fertilizer. The amount of water needs to be controlled from 1 to 2 months before flowering. No water control is needed in winter. Irrigate at the right time at other times.
We harvest the mangosteen fruit in the early morning or late afternoon. This is good for keeping the freshness of the fruit.
H、The economic benefits of mangosteen
The mangosteen tree has very few pests and diseases. It does not require much daylight, and semi-seclusion is possible. The fruit of mangosteen has a thick skin and is simple to keep fresh and packaged, and is resistant to storage for about 15 days. If each farmer plants 100~200 mangosteen trees in front of the house, behind the house, along the ditch, along the road or on the five sides of the land or on the barren slope, they can be put into production after 7 years. The life span is about 70~120 years. The production of adult trees based on 200-300 pounds, sales of 5 yuan per pound, minus the annual labor costs plus fertilizer costs, estimated at about 50,000. The annual output value of the household increases by 50~100,000 yuan.
