When high potassium is applied to grapes, is the content of potassium high in grapes?

The time of applying potash fertilizer to grape: during the period from fruit setting to fruit color conversion, potassium dihydrogen phosphate solution can be sprayed on the leaves, once every 7-15 days, 2-3 times in a row, before 9: 00 a. M. and after 5: 00 p. M. The potassium content of grape is high, which is 10 ~ 4-151mg per 100g grape, and contains more minerals and trace elements.

First, the time of applying potash fertilizer to grapes

1. Potash fertilizer is very important in the whole growth stage of grape, especially in the period of fruit growth, so the grape is called "potassium" crop. The application of potash fertilizer can promote grape fruit hypertrophy and accelerate ripening. At the same time, it can also improve the quality and storage resistance, as well as cold resistance, drought resistance, high temperature resistance and disease and insect resistance.

2. During the period from fruit setting to fruit color conversion, according to the soil fertility of the orchard, 5-10kg potassium sulfate per mu of vineyard can be applied, or appropriate amount of potassium dihydrogen phosphate solution can be sprayed on the leaf surface, once every 7-15 days, 2-3 times continuously.

3. Foliar spraying of potassium dihydrogen phosphate solution can promote grape growth and early ripening, accelerate vine aging, obviously improve grape resistance, and have obvious inhibitory effect on grape anthracnose, black pox and other major diseases.

4. The suitable time for foliar fertilizer spraying is before 9 o'clock in the morning and after 5 o'clock in the afternoon, the temperature at noon is too high, so it is not suitable to spray. When spraying, the leaves should be sprayed evenly on both sides, and 60kg can be sprayed per mu.

Is the content of potassium in grapes high

1. The content of potassium in grapes is relatively high, because grapes have different varieties, so the content of potassium in every 100g grape is 104-151mg, which is relatively high in fruits. Grapes also have the effects of tonifying qi and blood, tonifying liver and kidney, invigorating body fluid, strengthening muscles and bones, tonifying qi and blood, relieving cough and relieving annoyance, and relieving urination.

2, the main treatment of lung deficiency cough, palpitation and night sweating, weakness of qi and blood, rheumatism arthralgia, gonorrhea, edema and other symptoms, can also be used for the auxiliary treatment of shortness of breath, weakness of spleen, edema, adverse urination and other diseases.

3. Grapes contain more minerals and trace elements, such as calcium, iron, potassium and so on. Generally, when grapes are made into raisins, the content of sugar and iron will be relatively high, which is also a good tonic for children, women and people with weak anemia.

4. Studies have shown that eating an appropriate amount of fresh grapes every day can effectively prevent the occurrence of cardiovascular and cerebrovascular diseases, and is also beneficial to the health of patients with local ischemic heart disease or atherosclerotic heart disease.

5. The contents of resveratrol in grape skins and proanthocyanidins in grape seeds are higher than those in other parts of grapes and most other fruit trees, so they have high medicinal value and have become an important nutritional and medicinal commodity in the world.
