Method for interplanting of iris hybrids 'Louisiana' in taxodium 'Zhongshanshan' forest

Abstract

The invention relates to the field of plant planting, in particular to a method for interplanting of iris hybrids 'Louisiana' in a taxodium 'Zhongshanshan' forest. The method comprises the following steps that a, low-lying wetland with water depth lower than or equal to 40 centimeters is selected, ploughing is conducted, planting oil under water is flattened, and hole digging and land preparationare conducted; b, taxodium 'Zhongshanshan' soil ball seedlings or container seedlings with the diameter at breast height of 3 centimeters are selected and transplanted to the low-lying wetland, and the plant spacing in the rows is higher than or equal to 4 meters*6 meters; c, in the current year of taxodium 'Zhongshanshan' transplantation, through a plant division method, the iris hybrids 'Louisiana' is planted in the low-lying wetland under the taxodium 'Zhongshanshan' forest according to the plant spacing in the rows of 40 centimeters*40 centimeters. For the current condition of low utilization rate of the low-lying wetland in current production, the method for interplanting of the iris hybrids 'Louisiana' in the taxodium 'Zhongshanshan' forest is provided, the ornamental value under theforest is increased, and the utilization efficiency of land per unit area is improved.
