Abstract
The invention relates to a method for planting submergent plant in lake, which in detail relates to a method for planting aquatic weed. It is characterized in that it comprises following steps: selecting aquatic weed variety: selecting aquatic weed of no root, long plant and early germination; preparing seed bed: preparing framed net platform; replanting aquatic weed: planting aquatic weed into seed bed; fixing aquatic weed: managing seed bed: moderating seed bed position; forming new aquatic weed community; moving seed bed to weedless area for continuous growth. The method can plant submergent plant in water with depth of 1.5- 2.0 meter and transparency of lower than 50 cm, the submergent plant can grow perpetually and it is helpful to improvement and stability for aquatic ecologic environment.
Description
Technical field
The present invention relates to a kind of method of in the lake, planting planting submerged plant, specifically a kind of method of pasture and water plantation.
Background technology
Pasture and water can be used as the bait of aquatic animals such as fish, shrimp, crab, the things concealed when also being the attachment of fish-egg and shrimp, crab shell, and have the function of regulating waters ecology.Present pasture and water kind method for planting can be divided into sowing or transplant two kinds, and the pasture and water kind of plantation can be divided into three kinds of fluitante, emergent aquactic plant and submerged plants.The method of plantation fluitante and emergent aquactic plant is relative simpler, transplant or after planting general equal can be very fast formations group, and when planting planting submerged plant, the transparency regular meeting of water level and water influences it and photosyntheticly normally carries out, so it is bigger to plant difficulty.Generally include when in pond or stream, planting planting submerged plant reduce Chi Shui, sow or move slotting, progressively add high water level three big steps.The plantation pasture and water are adopted the mode of transplanting usually in the lake.The maximum characteristics of the pasture and water cultivation method in pond or stream are that water level is regulated easily, and the method that its first step reduces the pond water level is: utilize the height of water to draw water from row or with water pump, sow when making Chi Shui reduce to 10 ~ 20 centimetres and move slotting; The second step sowing or move slotting method and be: the pasture and water seed was soaked more than 12 hours, mix and stir grass seeds with earth after full pond sow; Perhaps fishing for pasture and water from other waters transplants; The water step that adds in the 3rd step is: along with the growth of pasture and water, progressively add high water level.The water level in lake is darker, and the plantation of its submerged plant comprises that kind selects, manually encloses and block, plant three big steps.The method that its first step kind is selected is: the pasture and water kind that selection has coring or unrooted all can survive, second step manually enclosed the method for blocking and is: 1. set up the fence facility in the more shallow waters of the depth of water, 2. in the fence district, plant fluitante, emergent aquactic plant and carry out artificial soilless culture, to reduce the wave of growing area, improve the transparency of water body; The method that the 3rd step planted is: submerged plant is inserted in the bed mud.The advantage of pasture and water cultivation method is a pasture and water survival rate height in pond or the stream, and the pasture and water kind that is suitable for planting is more.Its defective is: 1, need reduction water level is sowed or is moved slotting; 2, water level rising amplitude can not be too big, and not so grass seeds is difficult to germinate or causes that pasture and water are rotten; 3, but this method can only be applied in the waters of water level artificial adjustment; 4, when water transparency during less than 30 centimetres pasture and water be difficult for surviving.Not only labour intensity is big for the cultivation method of submerged plant in the lake, and pasture and water plantations is difficult for successfully, and its defective is: 1, Zai Zhong submerged plant be subjected to easily stormy waves impact and on float; 2, require the water level in growing area dry season to be lower than 1 meter, not so grass seeds is difficult to germinate; It is big to plant difficulty when 3, the water level of growing area surpasses 1.5 meters, and survival rate is low, and after removing fence, the pasture and water group of being planted is difficult to survival; Pasture and water were difficult for surviving when 4, water transparency was less than 50 centimetres.Because the existence of above-mentioned defective causes existing submerged plant kind method for planting to be difficult to apply above 1.5 meters lake region in the depth of water.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of method of planting planting submerged plant in the lake is provided, can be 1.5～2.0 meters in the depth of water, and transparency is lower than in 50 centimetres the waters carries out the submerged plant plantation; Utilize this method kind planting submerged plant to survive throughout the year, help the improvement of water area ecological environment and stable.
Main solution of the present invention is achieved in that
The present invention plants planting submerged plant and adopts following processing step in the lake:
1, the pasture and water kind is selected: the selection unrooted all can survive, plant is long and the pasture and water kind early of germinateing;
2, the seedbed device is made: at first make the netted platform of frame-type, the netted platform of frame-type comprises framework, rope and net sheet;
3, pasture and water are transplanted: pasture and water are planted into the seedbed device, with the rope on the seedbed pasture and water are vertically fixed on the net sheet;
4, the fixing pasture and water of transplanting of seedbed device: in growing area piling, and at the stake upper and lower side pulley is set, the rope on the seedbed links by pulley and stake, can oscilaltion;
5, seedbed device management: place for seed bed adjustment; Pasture and water form new group to expansion all around; Remove the spud pile of seedbed device; Remove behind the spud pile the peripheral Wu Cao district's continued growth of seedbed migration and stretch.
Rectangular or the triangle of the netted platform shape of frame-type of the present invention.
Netted platform of the present invention is made by the net sheet of 1.5～2.5 centimetres of meshes; Described net sheet can be an individual layer, also can be double-decker.
Place for seed bed of the present invention is adjusted to dried up 10～25 centimetres, to increase the illumination of pasture and water.
Seedbed of the present invention is isosceles triangle in water or the device font is arranged, to improve pasture and water plantation efficient.
Pasture and water kind of the present invention is selected waterweed or hydrilla verticillata etc. for use.
Compared with the prior art the present invention has the following advantages:
1, when the waters water level surpasses 1.5 meters, adopts the present invention to plant submerged plant and can solve pasture and water and be difficult to a difficult problem of taking root at lakebed; 2, when water transparency is lower than 50 centimetres, regulate the fixed position, seedbed, can satisfy the requirement of pasture and water growth to intensity of illumination; 3, the seedbed is reusable, helps reducing cost of investment; 4, it is fast that pasture and water group forms speed, and good stability helps the reparation of water area ecological environment; 5, the desirable place that can also multiply and live as aquatile, seedbed; 6, small investment, ecological effect is good, and helps the characteristics of waters benign ecological cycles.
