Embodiment 1
[0060] Such as figure 1 and figure 2 As shown, it is a schematic diagram of mixed planting of Bahia grass and vetiver in the water-fluctuation zone of the red soil area reservoir area in this embodiment. Plant 3 rows of Bahia Grass 2 at intervals of about 1m. The row spacing between Bahia Grass 2 is about 20cm.
[0061] Ecological restoration methods for the hydrofluctuation zone in the reservoir area of the red soil area:
[0062] In mid-June 2014, the bank slope of the reservoir was leveled off, and then planting grooves were excavated. The specifications of the planting grooves were about 15cm deep and 15cm wide. figure 1 and figure 2 Plant bahia grass and vetiver respectively, and then apply base fertilizer 10g / m 2 , cover the soil and compact it, and water and maintain it for 60 days to make the plant grow and develop normally.
[0063] According to observations, seedling replacement began to enter a stable growth period in August. In mid-September, the alternati...
Embodiment 2
[0067] Ecological restoration methods for the hydrofluctuation zone in the reservoir area of the red soil area:
[0068] The vetiver and bahia grass are mixed in rows. The row spacing of vetiver is about 1m, and 3 rows of bahia grass are planted at intervals in the middle. The row spacing between bahia grass is about 20cm. Configure planting, and vetiver is configured as a contour line.
[0069] Level the slope on the bank of the reservoir, and then excavate the planting trough, the size of the planting trough is about 15cm deep and 15cm wide, and plant Bahia grass and vetiver respectively by division method, 6 Bahia grass per clump, and keep the seedlings The above-ground part is about 5cm, and the underground part is about 5cm; Vetiver 4 plants / cluster, the seedlings keep the above-ground part about 20cm, the underground part about 5cm, and then apply base fertilizer 10g / m 2 , cover soil compaction, watering and maintenance.
Embodiment 3
[0071] Ecological restoration methods for the hydrofluctuation zone in the reservoir area of the red soil area:
[0072] The vetiver and bahia grass are mixed between rows, the row spacing of vetiver is about 1.15m, and 4 rows of bahia grass are planted between every two rows of vetiver, and the row spacing between bahia grass is about 15cm , Bahia Grass is planted according to the character shape configuration, and Vetiver is planted according to the contour line configuration. 8 plants / clump of bahia grass, about 7 cm aboveground part of seedlings; 6 plants / clump of vetiver, about 22 cm above ground part of seedlings.
