Whether too much alkalinity in the soil has an impact on grape growth and countermeasures?

The requirements of grapes on the soil are as follows: soil pH has a great impact on the nutrition of grape plants. In general, in a slightly acidic environment with a pH of 6, the grapes grow better.

In soils with excessive acidity and alkalinity (pH close to 4), growth is significantly poor, and in relatively alkaline soils (pH is above), yellow leaf disease begins to appear. Therefore, soils that are too acidic or too small need to be improved before grapes can be grown.

Here are some ways to adjust alkaline soils to acidic soils:

1) Application of sulfur powder per square meter of seedbed, mixed with 100 200g of sulfur powder, its acidic validity period can be maintained for 2 3 years.

2) Application of ferrous sulfate powder 150g of ferrous sulfate powder per square meter can reduce the pH value of the unit after application; For particularly clay soils, the dosage can be increased by 1 3.

3) Watering vinegar A small amount of potting soil at home, if its pH value is greater than 7, it can be watered with 150 200 times of edible vinegar, and then watered once every 15 20 days, and the effect is good.

4) Mixing pine needle soil Mixing pine needle soil is a fast and effective way to improve alkaline soil. Pine coniferous soil is made of decaying pine and cypress needles, stumps and other litter, which is highly acidic. Generally, 1 5 1 6 pine needle soil is mixed with alkaline soil to plant acid-loving flowers.

5) Pouring potassium dihydrogen phosphate solution In alkaline soil, iron is easily fixed and becomes unusable, even if more iron is applied, the effect will not be ideal. Therefore, potassium dihydrogen phosphate solution or other acidic fertilizer solutions can be used to irrigate the soil to make the soil weakly acidic, which can promote the dissolution of iron in the soil, which will be conducive to the absorption and utilization of iron by the roots of flowering plants.

Grape growth has a wide range of adaptation to soil pH, and can grow well on weakly acidic, neutral and weakly alkaline soils, while soils with a pH value of less than 4 or higher are not conducive to grape growth.

There are "terrace method" and "salt washing method" available for transforming saline-alkali land. Based on cost considerations, it is recommended that the soil environment above the pH value should be selected separately.

1.The amount of water required varies depending on the growing seasonEarly onset of growth provides enough for it to grow healthily3

When it comes to veraison, it is necessary to reduce the moisture**, there is a slight water stress to promote ripening! 4.Too much at this point destroys the root system (too much water).

Good luck homeopathy!
