Embodiment 1

[0038] The reed ears taken in the previous year were dried and chopped, and when the temperature reached more than 10°C, sowing was started, and the sowing rate was 75kg / mu. After the reed emerges, strengthen irrigation management, and the irrigation depth will not submerge the reed seedlings. When the height of the seedlings reaches 5cm, carry out thinning, and the seedling spacing is 2cm. With the growth and time of the seedlings, strengthen irrigation and fertilization. When the height of the seedlings reaches 20cm, the seedlings When the spacing reaches 6cm, the reed seedlings already have tillers.

[0039] Mix pond mud, vermiculite and river sand to make nutrient soil, which contains 50% by weight of pond mud, 25% by weight of vermiculite and 25% by weight of river sand, and fill 5kg of nutrient soil into a degradable plastic bag A nutrient soil bag is formed, and in the degradable plastic bag body, the content of polyvinyl alcohol is 10% by weight, and the content of sta...

Abstract

The invention provides an emergent aquatic plants planting method including the following steps: (1) transplanting seedlings of emergent aquatic plants into nutrient soil bags; (2) placing the nutrient soil bags with the seedlings into water, wherein the depth of the nutrient soil bags enables the naturally upright peak of the seedlings to approach the water level, and the depth of the nutrient soil bags increases correspondingly along with growth of the emergent aquatic plants so that the naturally upright peak of the seedlings can approach the water level; (3) placing the nutrient soil bags at the water bottom when the height of the emergent aquatic plants reaches 1.5-2.5m. The invention further provides a planting device for planting the emergent aquatic plants. The planting device comprises a guide column, a loading table and a draw cord, wherein the guide column is fixed in the water, a fixed pulley is arranged at the upper end of the guide column, the loading table is slidably connected onto the guide column and is used for loading the nutrient soil bags, one end of the draw word is fixed on the loading table, and the other end of the draw cord winds around the fixed pulley. The emergent aquatic plants planting method and device can achieve planting of the emergent aquatic plants in deep water zones with the water depth larger than 1.5m.

Description

technical field [0001] The invention relates to the field of fishery, in particular to a method for planting emergent plants and a planting device for planting emergent plants. Background technique [0002] As an important part of the aquatic ecosystem, aquatic vegetation plays an important and irreplaceable role in purifying water quality, improving the aquatic environment, providing food and shelter for animals, and maintaining the stability of the aquatic ecosystem. [0003] Emergent plants are one of the main components of aquatic vegetation. In lake ecosystems, emergent plants are located in the transition zone between aquatic ecosystems and terrestrial ecosystems, and their growth often shows characteristics that can be clearly distinguished from single aquatic plants. If it can inhibit the growth of certain algal blooms in the lake, effectively intercept the nutrients carried into the lake by the land runoff water body, prevent the resuspension of the water body sedim...
