Myriophyllum is a plant that grows in ponds, also known as Myriophyllum. It is a stout perennial submerged plant, with developed rhizomes and spreading in underwater silt. Its stem is cylindrical, multi-branched, with alternate leaves on the water surface, lanceolate, stout and bright green. On the leaves exposed on the water, sometimes there are water drops, which are crystal clear, shiny and very beautiful.

Myriophyllum grows in ponds, ditches and swamps all over China. It is often mixed with Myriophyllum. It likes slightly alkaline soil and warm, humid and sunny environment. It grows vigorously in summer and slowly in winter, but it is resistant to low temperature and can be harvested all year round.

In fish, shrimp and crab ponds, Myriophyllum can be used as bait, shelter and spawning ground, as well as feed for pigs and ducks and as ornamental plants. More importantly, Myriophyllum has high environmental protection value.

The roots of Myriophyllum can absorb nitrogen and phosphorus in sediments, and can also use nutrients in water through stems and leaves. After nitrogen and phosphorus are absorbed, they can synthesize the structural components of plants themselves, and some heavy metals and organic substances toxic to Myriophyllum can be stored or degraded in the body after detoxification. When harvesting Myriophyllum, the nutrients in the pond will also be exported from the water, so as to purify the water.

In addition, the study shows that the removal rate of ammonium nitrogen, nitrate nitrogen and total nitrogen in sewage by Myriophyllum is as high as 90%. Moreover, no matter in which season, Myriophyllum has a good purification effect on sewage and eutrophic water, and has a good tolerance to weather and temperature changes, so it is often used as a water purification tool for ecological engineering.

In addition, Myriophyllum can also be used in pig industry. The density of pig breeding is too high, which easily exceeds the environmental carrying capacity and causes pollution. Treating pig wastewater with Myriophyllum is an effective pollution control method, and Myriophyllum can also be used as pig feed, killing two birds with one stone, which can greatly improve the efficiency of raising pigs.

At present, the main propagation mode of Myriophyllum is cuttage, which is mostly carried out from April to August every year. Can be cultured in fresh water with moderate hardness. In case of planting and breeding problems, you can consult experts on the cloud breeding platform, which is the world's largest agricultural science and technology question and answer website, and every question raised will be answered within 2 minutes. In the operation, it is best to choose the stem tip with a length of 7-9 cm as the cutting, so that the new plant will grow rapidly.

The seeds of Myriophyllum can be preserved for several years in the drought period, and there is a dormancy period, and the dormancy is released in the next spring. Seeds can germinate in darkness and light, and germinated seedlings can float on the water and spread with the water.
