Abstract

The invention provides a method for sowing Potamogeton crispus turions, belonging to a planting technology of submerged plants. The method comprises the following steps: on the October of each year, acquiring the Potamogeton crispus turions; stirring dry clay with water until the clay becomes wet clay which can be kneaded into balls with hands and is basically unsticky to the hands; kneading the wet clay into a clay ball as big as an egg; putting the Potamogeton crispus turions into plant ash, and evenly stirring; pressing the mixture into the clay ball with fingers; extruding the clay ball, and causing the mixture to be fixed in the clay ball; rolling the clay ball in the plant ash; taking out and drying for 1-2 hours; and sowing based on the density of 10-20 pieces/ square meter in a target water body region required sowing, thus the Potamogeton crispus turions can be fixed, germinated and propagated in the region. The method has the advantages that the Potamogeton crispus turions can quickly sink and be fixed on a water bottom because of being covered by the clay, the Potamogeton crispus turions can be prevented from drifting, and the planting efficiency is improved; and meanwhile, nutritions required for the growth of the Potamogeton crispus turions are increased because the plant ash is used, thus the Potamogeton crispus turions grows to be more flourish. The method has the advantages of low cost, obvious effect and simplicity.

Description

A kind of type of seeding of curly pondweed rigid bud

Technical field

The present invention relates to the water caltrop sowing, relate to the type of seeding of curly pondweed rigid bud particularly at freshwater lake, reservoir, wetland.

Background technology

Submerged vegetation is the basic boom of water ecosystem, and one of water caltrop submerged plant that to be China common, have for fish and other aquatic animals provide spawning ground and sanctuary, fixedly bed mud, function such as purify water.Water caltrop mainly is grown in the bottom of freshwater lake, reservoir, generally germinates at 10--11 month curly pondweed rigid bud in China south, to the death in 6-July of next year, belongs to therophytes.

Curly pondweed rigid bud breaks away from the back from plant corpus to be propagated with stormy waves and current, sprout at random, so curly pondweed rigid bud is difficult in our desired zone and sprouts breeding often in a certain region clustering breeding.In order to address this problem, the main at present mode that adopts artificial curly pondweed rigid bud sowing, but directly broadcast sowing curly pondweed rigid bud, and can't solve clint equally easily with stormy waves and current drift, make it sprout the problem of breeding in desired zone.

Summary of the invention

The objective of the invention is, a kind of type of seeding of curly pondweed rigid bud is provided.This method adopts clay parcel curly pondweed rigid bud, makes curly pondweed rigid bud to fix, to sprout and breeding in the water body zone of expectation.The present invention is simple and effective, with low cost, is a kind of good method of curly pondweed rigid bud sowing.

In order to achieve the above object, the present invention adopts following technical scheme:

A kind of type of seeding of curly pondweed rigid bud, the method includes the steps of:

1) gets curly pondweed rigid bud annual October;

2) dry clay is added water be stirred to can pinch with hand agglomerating, and tack-free substantially damp clay;

3) damp clay is pinched into the clay group of egg size;

4) curly pondweed rigid bud being put into ash stirs;

5) get 1-2 curly pondweed rigid bud and be pressed into respectively in the clay group, push clay group then, make curly pondweed rigid bud be fixed in the clay group with finger;

6) the clay group that will be fixed with curly pondweed rigid bud puts into ash and rolls, make clay group evenly be stained with ash after, take out airing 1--2 hour;

7) in the target water body zone of needs sowing, according to 10--20/square metre density uniform broadcasting, curly pondweed rigid bud just can be fixed, sprout and breed in this zone.

Advantage of the present invention is, because curly pondweed rigid bud has the parcel of clay, can sink to and be fixed on the bottom rapidly, thereby avoid causing the curly pondweed rigid bud drift because of stormy waves and flow action, the water body zone that makes curly pondweed rigid bud to be fixed in to plant, improved plantation efficient, the use of ash has simultaneously increased the required nutritive salt of curly pondweed rigid bud growth, makes that the curly pondweed rigid bud growth is more luxuriant.The present invention is with low cost, and method is simple, and effect is remarkable.

Description of drawings

Fig. 1 is a curly pondweed rigid bud parcel schematic diagram.

Wherein: 1 is that curly pondweed rigid bud, 2 is that clay group, 3 is ash.

Concrete implementing measure

Below in conjunction with accompanying drawing, the present invention is further illustrated.

1) gets curly pondweed rigid bud 1 annual October;

3) damp clay is pinched into the clay group 2 of egg size;

4) curly pondweed rigid bud 1 being put into ash 3 stirs;

5) get 1-2 curly pondweed rigid bud 1 usefulness finger and be pressed into respectively in the clay group 2, with palm extruding clay group 2, make curly pondweed rigid bud 1 be fixed in the clay group 2 then;

6) the clay group 2 that will be fixed with curly pondweed rigid bud 1 puts into ash 3 and rolls, make clay group 2 evenly be stained with ash 3 after, take out airing 1--2 hour;

7) in the target water body zone of needs sowing, according to 10--20/square metre density uniform broadcasting, curly pondweed rigid bud 1 just can be fixed, sprout and breed in this zone.
