What kind of fertilizer is good for planting grapes
Grape cultivation mainly uses solid inorganic fertilizers. The method of combined application of two fertilizers should focus on applying fertilizers in trenches. It should be noted that for grapes planted in the ground, due to their vigorous growth and larger root systems, they need to be supplemented with fertilizers containing nitrogen in the early stage. After they start to bear fruit, the use of phosphorus and potassium fertilizers can be gradually increased, which can help the grape fruits to grow larger and sweeter.
Main fertilizers for planting grapes
Solid inorganic fertilizers are mainly used. According to the growth and development needs of grapes, urea is applied three times in the first year of planting, 50 grams per plant each time; compound fertilizer is applied twice, 100 grams per plant each time. Annually, 9 kilograms of urea and 12 kilograms of compound fertilizer are applied per mu, which is 1/5 and 1/4 of the topdressing amount per mu for soil cultivation, respectively. Trace elements are supplemented by foliar spraying, 2-3 times combined with pesticide spraying throughout the year. For the best base fertilizer for planting grapes, strive to combine organic and inorganic fertilizers: 1000-3000 kilograms of manure, 40 kilograms of urea, 25-50 kilograms of ordinary superphosphate, 20 kilograms of potassium sulfate, 3 kilograms of zinc sulfate, 3 kilograms of boron fertilizer, and 12.5 kilograms of ferrous sulfate. For topdressing fertilizers for grapes, apply 30 kilograms of urea, 25 kilograms of ordinary superphosphate, and 20 kilograms of potassium sulfate per mu. After that, apply a fruit-strengthening fertilizer every 20 days or so. Generally, 2-3 applications are needed each year, with the same amount as the first application. What kind of fertilizer is good for grapes during the growing period: After grapes germinate, fields with weak shoot growth or uneven germination need to be supplemented with fertilizer to strengthen the branches during the budding stage. The amount per mu is: 20 kilograms of urea, 25 kilograms of ordinary superphosphate, and 15 kilograms of potassium sulfate. What kind of fertilizer is good for grapes during the fruiting period: After the grape fruits start to color slightly, apply a sugar-increasing and coloring fertilizer, with 30 kilograms of urea, 25 kilograms of ordinary superphosphate, and 30-35 kilograms of potassium sulfate per mu.The correct method of fertilizing grapes
The method of combined application of two fertilizers should focus on applying fertilizers in trenches, with a trench depth of 20-30 centimeters and a distance of 60-70 centimeters from the trunk. The technical key points of the combined application method of two fertilizers are that the nutrients should be complete, with organic fertilizers as the main component. The principle is to combine organic and inorganic, biological and chemical, and major elements with trace and minor elements to avoid single-component fertilizers.Precautions for fertilizing grapes
