The difference between water accumulation grass and centipede grass

Shuiyun grass and Pteris vittata are two similar plants, which are easy to be confused. The following editor will introduce the difference between water grass and centipede grass.

I. the difference between water grass and centipede grass.

Pteris vittata is a terrestrial pteridophyte of the genus Pteris, which is a terrestrial plant of the genus Pteridopteris. In addition, the plants of Pteris vittata are stout and soft, while the plants of Pteris vittata are long and narrow, and the wood is hard.

2. cultivation techniques of Pteris vittata

1. Rooting culture

The germinated green balls grown on the subculture medium were transferred to 1/8MS+0.2 mg / L NAA medium, and they could basically take root after 3 weeks, so it is feasible to use low concentration medium and NAA to induce rooting.

two。 Seedling training and transplanting

The transplanted prothallus can survive on wet peat soil, and the survival rate of seedlings with roots is about 90%.

3. Natural sowing and reproduction

The spores of Pteris vittata seeded on filter paper and naturally germinated on the filter paper in petri dishes began to germinate on the 7th day, and the germination rate was 95%. In the statistical test of germination rate, due to the rapid germination of spores, the germination rate statistics can be completed before a large number of microorganisms grow on filter paper, so it is more appropriate to test the germination rate on filter paper.

4. Sow seeds on peat soil

The spores of Pteris vittata were sown directly into the peat soil and kept moist, and the prothallus could be seen in about 20 days. The sporophyte formed by natural sowing is relatively robust, and the statistical survival rate is 96% after transplanting to the flowerpot for 2 months.

Shuiyun grass is often used as aquarium cultivation, generally used as mid-scene, background grass and so on.
