Soil requirements for grape cultivation

Grapes are not strict with the soil, so they can be cultivated in loose sandy loam or light loam. This type of soil is more helpful for subsequent drainage and better fertilizer absorption. The clayey and heavy soil is not conducive to the growth of grapes, poor air permeability and difficult to drain in rainy days.

Soil requirements for grape cultivation

1. The most suitable soil for grape growth is sandy loam or light loam with loose soil, moderate porosity and small bulk density. This kind of soil has good properties of aeration, drainage, water and fertilizer conservation, which is beneficial to the growth of grape roots. Although the sandy soil is loose and permeable, good drainage, few weeds, light diseases and insect pests, the grape nodule aphid is not easy to reproduce, the temperature difference between day and night is large, which is favorable for nutrient accumulation, but the nutrient content is low, the fertilizer and water retention is poor, the thermal conductivity is high, and the temperature increases. Plants are vulnerable to freezing damage in winter and spring. Grapes grown in this kind of soil often mature early, have a high sugar content, but have smaller grains.

2. The soil containing a lot of gravel and coarse sand is also suitable for grape cultivation, which not only has good ventilation and drainage, but also has a large temperature difference between day and night, which is beneficial to nutrient accumulation, flower bud formation and fruit quality.

3. The sticky and heavy soil is the most disadvantageous to the grape, because of its poor air permeability, it is easy to accumulate water in the rainy season, suffocate the root, promote the activity of anaerobic microorganisms, poison the root system, and it is easy to harden in drought, which is disadvantageous to the root system, aboveground growth and fruit quality of grape.
