Van Dien NPK fertilizer: Satisfy the nutritional needs of orange trees in the fruiting period

Taking care of orange trees during the fruiting period is very important. This is the period when the orange fruit grows very strongly, the ability to accumulate powdered sugar in the fruit increases. Due to the requirements of soil, nutrition and characteristics of orange trees, many orange growing areas have focused on using Van Dien fertilizer and have given high efficiency.

Orange Can be grown in many places, but because the bran root system absorbs nutrients, it mainly grows on topsoil from a depth of 50cm or more, prefers loose, aerated soil but must ensure enough nutrition and good moisture. stable, so only some regions with specific conditions can effectively cultivate oranges. According to scientific calculations, an average of one ton of oranges is removed from the soil: 1.7kg N; 0.5kg P205; 3.2kg K and secondary and trace substances. The soil suitable for growing oranges has a thick, porous, well-drained cultivation layer, with alkaline pH from: 5.5 – 6.5. When the soil acidity is lower than 5.5, the roots will be toxic by Fe, Al, the plants are susceptible to lack of nutritional factors such as: Ca, Mg, P and Mo, the activity of soil microorganisms is also affected. reduced low. The nutrition trace elements such as Zn, Cu, Mn, Fe, B0, M0, C0…. Micronutrients also have the effect of improving the soil, helping to reduce the number of seeds, increase the flavor, beautify the fruit, contribute to increasing the yield and quality of oranges when harvested. Lack of trace elements makes the plant imbalanced in nutrition, prone to yellow mosaic disease, flower drop, young fruit drop, diseased plants and abnormal growth. Due to the above requirements for soil, nutrients and tree characteristics, many concentrated orange growing areas have chosen to use it Van Dien fertilizer n and gives very high efficiency. Lan Van Dien has a fairly high ratio of Calcium, Magnesium, and Silicon, so it has the effect of reducing acidity, gradually raising the pH of the soil, suitable for orange trees. The land for growing oranges is mainly grown on hills, gardens, and riverbanks where it is high and steep; easily washed out and lack of intermediate and trace substances. Lan Van Dien is a slow soluble phosphorus, only soluble in weak acid solutions secreted by the roots, where the plant needs to dissolve the fertilizer, so it is limited to being washed away. Besides Lan Van Dien It also adds essential nutrients and trace elements for plants. Produced from Van Dien fused phosphate fertilizer, specialized NPK multi-element fertilizers for oranges are different from some common NPK fertilizers, in addition to nitrogen, phosphorus, and potassium, there are also medium and micronutrients. Van Dien NPK provides 16 essential nutrients for plants with a high and balanced nutrient ratio NPK Van Dien provide enough 16 essential nutrients for plants with a high and balanced nutrient ratio. For oranges in the business period, the amount of fertilizer invested depends on the quality of the soil in the region, the age of the tree and the annual yield. In 1 year, in combination with rotten organic fertilizer, Van Dien fertilizer is divided into 4 fertilization periods: 1st: After harvesting the fruit. Apply a root of 10-15kg of organic fertilizer, 3-5kg of Van Dien phosphorus. Three times after applying with multi-factor fertilizer NPK Van Dien: 13;3:13 or 12-8-12, 12-12-17. Phase 2: Around March-April, after the physiological fruit drop. Oranges from 4 to 7 years old, apply a 1-1.5kg root; oranges from 8 – 11 years old, apply a 1.5 – 2kg root; Oranges over 11 years old, apply a root of 2.5 – 3kg. 3rd round: In June-July, fertilize fruit after stabilizing the number of fruits on the tree. Oranges from 4 – 7 years old, apply a root of 1.5 – 2kg; oranges from 8 – 11 years old, apply a root 1.5 – 2kg; Oranges over 11 years old, apply a root of 2.5 – 3kg. Phase 4: In September-October, 1 – 1.5 months before harvest, apply multi-factor fertilizer NPK 12:12:17 to limit the second physiological fruit drop and limit fruit cracking, especially weight gain. yield and fruit quality at harvest. Oranges from 4 to 7 years old fertilize a root 2 – 2.5kg; oranges from 8 – 11 years old, apply a root of 2.5 – 3kg; Oranges over 11 years old fertilize a root of 3.5 – 4kg. Van Dien fertilizer provides a full balance of all kinds of macronutrients, intermediate and micronutrients to satisfy the nutritional needs of orange trees throughout the crop year. Van Dien fertilizer helps orange trees grow healthy, balanced, green leaves, bright, thick leaves, less pests, high fruiting rate, large, uniform fruits, reduce fruit drop, help balls, Large, smooth, especially when ripe, the dark yellow skin is very attractive, high yield, increased sweetness, stronger flavor and longer shelf life. How to fertilize: * If, after harvesting the fruits of the previous crop, the incision was made and then fused with phosphate fertilizers and rotted organic fertilizers were applied, now apply fertilizer according to the old canal: spread fertilizer along the canal and then cover with soil, leaves cover the manure. * Can spread fertilizer according to the projection of the canopy back, about 50-60cm from the root, spread the fertilizer and then cover with soil, if it is dry, it must be watered; You can soak the manure to dissolve it and then mix it with water to irrigate.
