Abstract:

In order to find out the suitable covering materials for protected cultivation of grape, three kinds of covering materials were used to investigate the effects of different covering materials on the number of grape root system, soil water content, pH, EC, and enzyme activity indexes of soil urease, phosphatase, invertase and hydrogen peroxidase in different soil layers. The results showed that the proportion of absorbable roots with diameter less than 2 mm was 59.46%, 71.43% and 52.53% respectively under the treatments of non-woven cloth, ground cloth and plastic film covering, while the number of roots with diameter of 2-5 mm was 41.10% in the control; the total number of roots of protected cultivation of grape could be significantly increased by covering materials. The distribution proportion of roots with diameter of 0-20 cm could be significantly increased by covering non-woven cloth (36.93%), which was 15.07% for control; covering materials had little effect on soil water content, but covering materials could increase the pH value of shallow soil and reduce the EC value; covering materials had a certain effect on soil enzyme activities, especially on the activities of soil invertase and hydrogen peroxidase. It could be seen that the use of covering materials in protected cultivation of grape had a certain positive effect on grape root growth and soil physical and chemical properties, and the non-woven cloth with better air permeability was the best covering material.
