In 2009, after studying and visiting the model of growing pink-fleshed, green-skinned grapefruit in Quang Binh, Mr. Nguyen Thanh Quang, Trung Tam hamlet, Nghia Hieu commune, decided to cut down the ineffective old orange plot and the lemon plot to plant 150 pink-fleshed, green-skinned grapefruit trees, a Southern variety. This grapefruit variety prefers many types of soil, especially barren soil, is easier to grow and care for than orange trees, has even segments, and sweet fruit. In particular, this grapefruit produces two crops a year, the main crop in mid-July, August and the late December crop of the year.
In 2013, after 5 years of planting, the pink-fleshed green-skinned grapefruit yielded its first crop of fruit. Although the quantity was not much, it still brought in an income of about 300 million VND. In 2014, the family sold about 12 tons of grapefruit, at an average price of 30,000 VND/kg. The main crop brought in an income of about 300 million VND, and the pre-Tet crop brought in an income of 250-300 million VND.

By 2015, grapefruit output increased to 22 tons and this year his family had another bumper crop of grapefruit with nearly 100 trees, each bearing over 100 fruits, including one tree with nearly 300 fruits. Mr. Quang shared that this year's output is expected to be 1.5 times higher than last year. If prices remain stable, his family is estimated to earn around 400-500 million VND.
Sharing the secret to having a lot of grapefruit, Mr. Tran Thanh Quang said: Growing grapefruit is not difficult because there are few pests and diseases, just pay attention to fertilizing properly so that the fruit is sweet and not too big, because too big fruit will not be delicious and will affect the grapefruit root. With this grapefruit variety, after 2 years of planting, the tree will bear fruit, from the 4th year onwards it will bear a lot of fruit. In addition to selling fruit, each year his family sells 5,000 to 8,000 seedlings to households in the area.
Seeing the effectiveness of this grapefruit variety, many households in Nghia Dan district as well as neighboring districts have propagated Quang's grapefruit.

Techniques for planting and caring for green-skinned grapefruit: - Green-skin pomelo planting season: can be planted year-round, best planted in spring (February-April) and autumn (August-October). Planting density: depends on soil quality and intensive farming ability. Flat land (alluvial): 6m x 7m. + Garden land, hills (gravel): 4m x6m *How to plant green-skinned grapefruit: Dig a hole: Alluvial soil, dig a hole (60cm x 60cm x 60cm). If the ground is low and has poor drainage, you can build a mound or raise the bed. Hilly soil, dig a hole 80cm x 80cm x 80cm, plant in a staggered style. - Basal fertilizer/1 tree: Fertilize each hole depending on soil fertility. Dong Tam Xanh organic fertilizer: 15_20kg. Phosphate fertilizer (superphosphate) 1kg, Potassium sulfate 0.5kg, Lime powder 1kg The topsoil is mixed with fertilizer and put at the bottom of the hole, the remaining soil is left on the surface of the hole, the base is 10-20cm higher than the garden surface (digging the hole and fertilizing must be done 1-2 months before planting). - How to plant: cut open the plastic pot, place the tree in the hole, fill the soil about 2-3 cm deep. Compact the soil around the pot, create a 3-5 cm concave surface around the base for watering. Insert the pole and tie soft wire to secure the plant, water it and cover it with hay or straw to keep the plant moist. 2.Plant care after planting - Regularly keep the plant moist. Water with foliar fertilizer Lay-O, Combi-5, Komix... and fertilize regularly 1-2 times/month. - Prune to create a canopy of 50cm for level I branches, 30cm for level II branches and 20cm for level III branches. Create a branch frame and wide canopy for the tree, good for photosynthesis. - Fertilize trees that have not yet produced fruit, fertilize once before each growth period. There are usually 3 growth periods a year in spring, summer and fall. - When the tree bears fruit: fertilize 4 times/year: + After fruit harvest, apply organic fertilizer + 100% phosphorus, 20% nitrogen, 100% lime. + During the flowering preparation period, fertilize with nitrogen, potassium, and zinc. + During the fruit-limiting period, help the fruit grow quickly by fertilizing with nitrogen, potassium, and boron. + Fertilize with potassium and sungar 1 month before harvest. |
