Three-dimensional network construction procedures and key link control
Slope finishing molding - fine flat (application of bottom fertilizer) - laying net - fixed - covering soil - sowing (mechanical soil spray) - covering soil - covering fiber cloth or straw - sprinkling water
In the above several processes, it is necessary to do a good job of controlling:
1 The slope is strictly arranged according to the requirements of the design drawings (the three-dimensional net is used with caution on the gravel slope). The base fertilizer can be used with decomposed organic fertilizer and quick-acting fertilizer. If the pH value is not suitable, the work of adding improved substances can be carried out at the same time.
2 When covering the net, the net should be attached to the slope as close as possible to prevent it from hanging. When laying, the net should be kept flat and no wrinkles should be formed. From top to bottom, the nets overlap 10cm.
3 When fixing, use u-shaped nails or disposable bamboo chopsticks. The length of bamboo chopsticks is generally 15cm, the spacing is 50cm, and there are 6 bamboo chopsticks per square. When the net is fixed, the soil must meet the requirements of the soil: finely divided, fertile, and the ph value is moderately moist. Especially for the project, the earthwork is large, the soil is difficult to be taken, and the transportation distance is long. The soil source should be prepared in advance and piled up for standby.
4 When watering, be sure to use a spray of water to prevent runoff.
5 Grass species should choose roots developed, deep in the soil, at least one kind of stolons developed, such as: dog tooth roots, planting trees and so on.
