How to apply potassium fertilizer to grapes
Answer: Potash fertilizer can promote the expansion and ripening of grape fruit, improve the quality and storability, promote the thickening of the branches, and improve its ability to resist cold, drought, high temperature and pests. According to the soil fertility of the orchard, from 5 to 10 kg of potassium sulfate per acre of vineyard can be applied after the grapes are set to the fruit color change period. Potassium dihydrogen phosphate solution can also be sprayed on the leaves, once every 7 to 15 days, and sprayed for 2 to 3 times. It plays a significant role in promoting grape enlargement, early ripening, accelerating aging of branches and vines, and improving grape resistance. At the same time, it can also significantly inhibit the main diseases such as grape anthracnose and acne. Foliar spraying should be carried out before 9 am and after 5 pm, and it should not be sprayed at high temperature at noon. The leaves should be sprayed evenly on both sides, with 60 kg of fertilizer solution per acre as well. Disclaimer: Some articles of this website are transferred from the Internet.
