Submerged plant thrown seedling cultivating and planting method

Abstract

The invention discloses a submerged plant thrown seedling cultivating and planting method which comprises the following steps: A, shearing dry straw or plant fibers into sheared sections and adding water to mixing dry clay and the sheared sections into muddy cultivation base materials; B, arranging the cultivation base materials into a seedling growing cavity disk; C, flattening the cultivation base materials filled in the seedling growing cavity disk; D, sowing or planting seeds and dormant buds of submerged plants into cavity holes through stem sections; E, placing the sowed seedling growing cavity disk into a seedling growing water tank; F, fishing the seedling growing cavity disk from the seedling growing water tank to be transported to a planting site when the submerged plants grow to 10 to 15cm; G, taking a seedling block out of the seedling growing cavity disk to be directly thrown into water of a target planting plot; and H, inserting root systems into bottom mud after the submerged plats survive. The submerged plant thrown seedling cultivating and planting method avoids secondary pollution on water bottom environment, prevents seedlings from floating up, saves labor resources and material resources and lays foundation for mechanical planting of the submerged plants by means of the small size of modularization seedlings.

Description

[0001] technical field [0002] The invention relates to a rapid recovery of submerged vegetation and rapid construction of submerged plant community structure in the process of water ecological restoration or water body landscape construction, in particular to a submerged plant throwing seedling cultivation and planting method. Background technique [0003] Aquatic vegetation restoration is a key step in the process of water ecological environment restoration, especially the growth of submerged plants plays a key role in water purification. The growth of submerged plants can increase the dissolved oxygen content of the water body, absorb nutrients in the water body, reduce sediment disturbance and increase the transparency of the water body. Due to the special environment for the growth of submerged plants, artificial cuttings need to be planted in the water, and the cuttings are not strong enough to cause the seedlings to float; the restoration of the soil seed bank requir...

AI Technical Summary

Problems solved by technology

Due to the special environment for the growth of submerged plants, artificial cuttings need to be planted in the water, and the cuttings are not strong enough to cause the seedlings to float; the restoration of the soil seed bank requires a large amount of engineering work, and transportation is inconvenient; the planting of submerged plants consumes a lot of manpower and material resources ; Throwing seedlings of submerged plants wrapped in mud may easily lead to unsuccessful planting of submerged plants; using plastic or other non-degradable media to cultivate modular underwater turf to restore submerged plants will cause secondary pollution to the underwater environment
