Can Duckweed Help Save the World?

by:J&D WATER     2019-08-20
What is duckweed?While few people have a vague idea of what duckweed is, many see it growing on top of canals, swamps, lakes and slow-moving rivers.Duckweed is the common name of several different kinds of floating plants in the class of annideae, ar family.Also known as Asian Water meal, khai nam, ducks-Meat, Fuping, water lentils.
Except Antarctica, duckweed is wild on every continent.It is easy to grow as an indoor aquatic plant or aquarium or garden pond.Many of its potential uses are currently being studied globally.
Duckweed in water conservation and environmental cleaningDuckweed benefits the water source it covers in several different ways.It helps prevent evaporation by providing shade and returning condensed droplets captured in the leaves.It provides a safe habitat near oxygen.The rich surface of Fry, tadpole and other cubs.
This is a great source of food for all the herbivores in the water.Duckweed also Removes Ammonia, waste from feces and harmful accumulation of bacteria and minerals.In water treatment, it can purify the water in the external storage tank and filter out the phosphate in the commercial fertilizer that is common in agricultural production.
off.
In the natural world, duckweed is a powerful biological repairer.It removes industrial pollutants such as heavy metals from contaminated lakes and eventually transforms them into ecosystems suitable for supporting healthy local wildlife.Researchers around the world are testing duckweed as a possible source of biofuels.
In the United States, the Department of Energy and Rutgers University, as well as the NC State University, are undertaking projects to assess duckweed as a potential crop for the production of clean, efficient and renewable energy.So far, this seems to be a good candidate for biofuels, as Duckweed grows rapidly, and the starch produced per square foot of planting area is about five and a half times that of corn, no needIn addition, unlike any fossil fuel, its production is clean and sustainable, reducing greenhouse gases rather than increasing more.In Asia, duckweed has been used as a food source to add soup, fried fries and curry.
People around the world use it as a cheap source of animal feed for raising from ducks that seem to have discovered this to chickens, pigs and tilapia.Researchers in Germany and India tested various strains and found that they were all edible, a specific species, and that Wolffia globosa (also known as Asian gouache) was protein and omegaFatty acids are widely considered to be the most beneficial fatty acids for health.The high-Protein and good fat content can make Asian water powder an important crop against food shortages around the world, especially in areas where it is malnourished due to high carbohydrate crops.
In fact, it grows wild on six continents, which means that in areas that are not suitable for traditional agriculture, it can be easily planted by anyone.It can grow on roofs or windows inside the city, or in rocky rural areas with insufficient soil at the top.It can grow in other places where it is difficult to find fresh green vegetables and sources of vitamin.
In fact, it doubled in 48 hours, which means that once the plant is filled with containers, half of the plants can be harvested continuously every two days, or 182 times a year.There is growing evidence that duckweed growing at the top of the pool significantly reduces the number of mosquitoes that may hatch water.One possibility is that safe Fry and other young carnivores are found in floating plants that devour mosquito eggs, larvae, and cocoons.
If properly managed, the introduction of local duckweed species into canals and other potential mosquito breeding sites can help prevent the spread of mosquitoesTo name just a few, infectious diseases such as malaria, dengue fever and Zika.The use of duckweed also limits the toxins that kill mosquitoes, but also brings other environmental benefits.Similarly, duckweed prevented algae from becoming plagues in its territory.
Harmful algae or harmful algae are related to many public health issues.Clearly, duckweed as human food or for livestock/pet food should be farmed responsibly and tested for quality and safety.It is not good for unscrupulous people to use it for environmental cleaning --Then sell it to animal feed or baby formula.
In addition, the local duckweed has recently become a pest in Florida because it comes from the Holy.The Bay of John was released to the Everglades.The floods seriously polluted agricultural runoff, mainly from sugarcane fields, resulting in excessive growth of duckweed, blocking the saw grass necessary for the fragile marsh ecosystem, mainly due to the fact that countless others have fallen into crisismade mistakes.
It is clear, however, that caution is needed when trying to solve one problem (water management) without causing another problem (swamp disaster.The introduction of duckweed in the new environment needs to be done seriously.Care should be taken to use the most common native species in the region.
Adding duckweed in the aquarium means continuing some extra work.Control is impossible in a natural environment.Before we act, we have to think, then act, and let duckweed solve our problem, not just another problem.
If you plan to grow your own duckweed as an aquatic plant, as a plant in an aquarium or garden pond, or as a free food source for families, pets or livestock, study it first.Make sure you really want some duckweed and if you choose to grow them, you can commit to proper care, including responsible handling (eating or compost) to remove the plants if necessary.It grows very fast, so you will deal with it a lot.
If you decide to give it a try, choose a natural local location to harvest your sample.That way.There is no doubt that you know that duckweed is native to your area (or at least has invaded ).You don\'t have this luxury if you buy it over the Internet.
Also, I assure you that no one will clean it up before duckweed sends it to you.Use your knowledge of the region, knowledge of the Internet and common sense to find a place to collect.Choose to stay away from road dust and waste gas, leather mills and other heavy metal polluters.
Find a stick in or near your yard, as big as a finger, and the longer the time, the better.There is never a convenient place to collect.Throw it in your trunk.Try to make sure your car will get you back and forth.
Check fluids.
Make sure you have a blanket, a flashlight with a new battery, a toolbox, a first aid kit, some trail mix and bottled water, a full box of petrol and spare tires just in case.The end is better-prepared.Tell someone else where you\'re going so they know where to look for you.Smelly insect repellent to prevent mosquitoes and want to stop anything else from getting too close.
A disposable sandwich container filled with about half the lidFill your tap water from home.Another responsible adult who can drive your car and is equipped with a fullMobile phone charging.Always bring someone with you when you feed or collect specimens.
They can sit in the car, as long as they can look at you throughout the process, they will point to you and laugh, if you are bitten by a snake, or have a broken ankle when you run away bravely, they\'re from angry hornets.Pay attention to the occasion and weather when foraging.At least, wear a long-sleeved t-Shirt and comfortable jeans, crew socks, strong closuretoe shoes.
The hiking boots are ideal for protecting the legs from snakes and have good traction.I always wear sunscreen, bug spray, sun-proof and ticking hats, sunglasses to protect my eyes and some kind of gloves.For duckweed, I suggest you eat it.Type thin latex gloves in case you touch the duckweed with your finger or something else near it.
Any one is better than no gloves.
Tuck all your clothes into each other\'s socks and boots.You prefer the creepy reptiles outside the clothes, where you can see them knocked down in your lianail dance.It\'s better than just feeling like there\'s something unknown crawling on the skin in your trouser legs.
You must believe me on this issue.
If you live in a place where crocodiles or crocodiles are your neighbors, be especially careful to collect duckweed, which are very good at hiding large underwater reptiles.Always pay attention to the environment around you.Harvest by the water with your stick.After you\'re done, you can leave the stick to the next person who might need it.
Transfer a small amount of duckweed on the stick to the water in your box.All you need to do is collect some tiny plants to start your own duckweed empire.The less you collect from the wild, the better.
This means that the workload of cleaning it is reduced, and the chances of dragging unwanted aquatic rides home are reduced --Hikers, for example, are like leaches.Make sure the lid is tight there!Once you get home with your box, take it to your backyard and park in the shade.Don\'t worry if the plants don\'t float to the top.
They did a good job.
Now go and throw your foraging clothes in the washing machine, take a shower and wash your hair carefully to make sure you don\'t tick (I really want to write \"or worse\" here \", but if I could think of something worse than the ticking on me, I would be scared.A few hours later, check the side of the box or if anything has climbed out on the lid.Obviously, do it carefully.Now see if there\'s anything swimming at the bottom.
With another pair of disposable rubber gloves, gently transfer the duckweed plant to the second container half full of water.Usually just slide around with your fingers.I like to use another disposable sandwich box.
I don\'t return exotic used containers to their intended use, but be sure to wash them by hand, mark their previous use with sharpie, and reuse them later for similar purposes.According to what you found alive in the first box, handle it properly.In the history of my foraging, I have brought the creepy reptiles back to my original collection point for freedom, and if there is a tick, drown it in alcohol, then ignite.
I have a soft spot for most creatures.
I don\'t like it inside.
When I collected the duckweed I brought home, I poured a few tablespoons of white vinegar into the water, gave it a good shake, let it sit for a while, and then turned it into normal tap water.Shake and rinse it again and let it sit on it and cover it, but don\'t tighten it.The next day, unless you see something other than duckweed, it may be ready for the next step.
It depends on how you want to use your duckweed.If I plan to use it as a water plant for an existing freshwater fish tank, I will start it in a temporary fish tank first.A snail or something like that may have sticky eggs attached to the leaves, and the initial cleaning has not changed.
It\'s best to go out with a test tank before polluting your main tank with predators or hard objectsto-get-rid-of pest.My duckweed (I harvested about half a cup and yes, it was a lot of work to clean up) went into boiling water.Five minutes later, I put it in a spoon.And throw it all in one.Vegetable fristaI hope there are only vegetables and eggs in it.
It was good!However, I haven\'t met any vegetables that I don\'t like yet.I think nature\'s free food is always better than what I bought at the grocery store, which is probably why even if we don\'t camp, I\'m obsessed with foraging and that was the first time I ate duckweedDuckweed may have unknown features and applications that no one has considered yet.It may also have hidden shortcomings that we need to find and solve.
But we can and should use duckweed wisely to help us accomplish many things that need to be done, such as preventing the spread of disease and ending hunger, including in the United States.It\'s amazing to think that small plants can help solve such a big problem.Think about all the problems we might solve as a species, if one day we agree that improving the world for future generations is the most important reason why we are here.
