Embodiment
Potamogeton pectinatus L has seminal propagation and vegetative propagation system efficiently.The seed generating capacity is bigger, easily gathers.Lake survey finds that the seed generating capacity of the Potamogeton pectinatus L of windward side is at 298-1524 grain m
-2Between, 794 m of average out to
-2Lee face seed generating capacity is 546-2632 grain m
-2, average particle 1627m
-2Pond seed generating capacity is 1115-3413 grain m
-2, average 2140 m
-2, but percentage of seedgermination is low, and less than 6%, thereby seminal propagation is little to the repopulate contribution.But, seed can improve germination rate through certain technical finesse.In annual 6-9 month, collect seed in Potamogeton pectinatus L growth location.The method of gathering seed is: Row Your Boat is selected the inflorescence that ripening fruits is arranged to Potamogeton pectinatus L growth location, and it is cut, and is immersed in the bucket that fills water, takes back.After taking back, seed is wanted disinfection (generally soaked 0.5-1 hour with 0.5% hypochlorous acid or soaked 5-15 minute with 0.1% mercury, use distilled water flushing again), preservation 40-60 days under 4 ℃ of left and right sides conditions again.Then, take out seed, available sand paper afterturn seed destroys kind of a skin, seed germination rate can be brought up to about 50% like this; At last, when treating that water temperature reaches 15-30 ℃ of scope, these seeds of handling are shed to the water body that will plant Potamogeton pectinatus L.The seed consumption is every mu of 1-2 jin.Points for attention: plantation water body depth of water scope is 0.05-1.2m, and when the depth of water was 0.8-1.2, transparency will remain on more than the 40cm, and water volume flow rate is less than 10m/s, the waters that stormy waves is relatively little.In addition, take precautions against herbivorous fishes or have the fish of destruction to exist to pasture and water.
Potamogeton pectinatus L also can be by stubble, root-like stock, stem tuber, underground stem tuber, basistipe on the ground and axil base portion be bred on the ground, wherein the most important thing is underground stem tuber and root-like stock, next year repopulate mainly come from underground stem tuber.The underground stem tuber modes of reproduction of Potamogeton pectinatus L is that domestic first is used: the collection of the underground stem tuber of a.: annual 8-10 month, selection is grown in shallow-water environment (the Potamogeton pectinatus L population of the depth of water＜50cm), along plant roots and stems, the bed mud with spade excavation top layer 30cm takes out stem tuber therein.B. stem tuber kind method for planting: an available diameter is that the pipe (length will determine that the depth of water is generally greater than 1.5m according to the water depth of plantation) about 8-15cm vertically is positioned in the water body that needs plantation; (the hammer head diameter is less than 6-13cm to use a pile monkey then, be convenient to insert in the above-mentioned pipe) insert in the above-mentioned pipe, make a call to a dark 10-20cm cave at the bottom, will put into 2-5 stem tuber in the cave then, fill out the thick soil of 5-20cm again, cover stem tuber and get final product.Planting density is 1-10 cave/m
