Step 2), planting the aquatic weeds 5 in the hanging baskets 4 in the step 1), and adjusting the height of the hanging baskets 4 under the water surface through the rope length adjusting pieces 2 according to the stem growth height of the aquatic weeds 5 in different seasons, wherein ammonium nitrogen, nitrate nitrogen and total nitrogen in the water are mainly absorbed by microorganisms, so that plants with developed roots and high absorption rate are selected as an effective way for purifying the water in the pond at present.
The height of the hanging basket 4 under the water surface is adjusted according to the growth height of the stem of the aquatic weeds in different seasons. The height of the hanging basket under the water surface is adjusted to be 40cm in 3 months every year; adjusting the height of the hanging basket below the water surface to be 20-30 cm after 4-8 months; and adjusting the height of the hanging basket below the water surface to be 50-60 cm for 9-12 months and 1-2 months.
Meanwhile, the tape grass and the hydrilla verticillata are perennial strong and submerged herbs, are planted for times for years, have high economic benefit and greatly reduce the purification cost of the pond water body.
The invention relates to a method for purifying pond water quality by planting waterweeds in potted type hanging baskets, which is applicable to a rich water body with the transparency of 15-40 cm, wherein the potted type hanging baskets for planting the waterweeds are hung in water, the height of the hanging baskets under the water surface is adjusted by a rope length adjusting piece according to the growth height of the stems of the waterweeds in different seasons, rhizomes of the waterweeds are utilized to provide habitat for underwater microorganisms, the number of underwater microorganism populations at the rhizomes of the waterweeds is increased, the underwater microorganisms attached to the rhizomes of the waterweeds can well absorb rich nutrients in the pond water body, the purification effect of a water body pond is enhanced, submerged plants such as tape grass and hydrilla verticillata can grow robusta and can greatly reduce the purification cost of the pond water body after times of planting and growing for many years.
Example 1
The second experiment base intensive culture pond circular trench in the school of the aquatic college of Huazhong agriculture university has the total area of 2.8 mu and the trench depth of 2.8 m and the water depth of 1.5-2.0 m, and mainly accommodates the drainage of the culture pond of the base, and the main physical and chemical indexes of the water body in the culture season are as follows: the transparency is 15-30 cm, the ammonia nitrogen is 0.05-2.61 mg/L, the nitrite nitrogen is 0.05-0.65 mg/L, and the total phosphorus is 0.41-1.93 mg/L. Because of low transparency, submerged plants are difficult to grow, and further the exertion of the water quality purification capacity of the circular ditch is restricted.
The concrete treatment method comprises the following steps:
1. 2 steel wires are erect along the irrigation canals and ditches indulge to the basket cultivated in a pot of installation, and steel wire interval 2m, steel wire are used for fixed hanging flower basket, and interval 2m sets up 1 rope length adjustment spare on the every steel wire to control hanging flower basket height under the surface of water. In 3 months, the height of the hanging basket below the water surface is adjusted to be 40 cm; in 4-8 months, adjusting the height of the hanging basket below the water surface to be 20-30 cm; in months of 9-12 and 1-2, the height of the adjusting hanging basket under the water surface is 50-60 cm. Herba Swertiae Dilutae and hydrilla verticillata are planted in the herba Lysionoti Pauciflori.
2. The survival rate of the sowthistle and hydrilla verticillata transplanted by the growth of the submerged plant is close to 100 percent, and the submerged plant grows well all the year round.
3. The main indexes of the water body after the water quality purification effect treatment are as follows: the transparency is 0.5-1.5 m; 0.04-0.50 mg/L of ammonia nitrogen, 0.05-0.21 mg/L of nitrite nitrogen and 0.07-1.15 mg/L of total phosphorus. Through the basket hanging mode, the submerged plant can grow in the fertilizer water with lower transparency, and through the purification effect of the submerged plant, the self-purification capacity of the water body is enhanced.
The implementation case shows that the method can realize the successful transplantation and planting of the submerged plants in the low-transparency water body, and further can improve the self-purification capability and the water body restoration effect of the water body.
Finally, it should be noted that the above examples are only used for illustrating the present invention and do not limit the protection scope of the present invention. In addition, after reading the technical content of the invention, the skilled person can make various changes, modifications or variations to the invention, and all the equivalents thereof also belong to the protection scope defined by the claims of the present application.
