While producing bioenergy, willow dwarf forest can also play a role in removing pollutants and managing the environment. Sweden has successfully used willow dwarf forest to treat urban wastewater, landfill leachate, industrial wastewater (such as wastewater from wood storage plants sprayed with logs), sewage sludge and sawdust. , mainly through plant absorption to reduce pollutants and excessive nutrients in water and soil, and promote the degradation of organic pollutants by soil microorganisms. This process is called phytoremediation.

Precautions for willow planting: when planting in holes, pay attention to: after the seedlings are delivered, trim the roots first, and then plant them immediately. Pruning should be scientific and reasonable, and the section must be smooth. When the soil is sticky, the planting hole should not be less than 80 cm× 80 cm× 60 cm. If it is necessary to reduce insect holes in the later stage, trichlorfon and other drugs can be evenly sprinkled into the holes, and weeping willows can inhale drug components when absorbing water during the growth process, thus releasing insects.
Willow knowledge expansion: willow planting skills: the so-called intentional planting of flowers, flowers do not grow, unintentional insertion, willow shade! If you want to plant willows, you'd better have a bigger flowerpot and put enough soil in it. The soil should not be too small and easy to die. That depends on the size of your willow. If it's big, you may not be able to grow it, because it's a little difficult in the dish! If it's not too big, you should first branch it and remove the smaller branches, because trees will carry out photosynthesis when they have leaves, so that the trees can send the water in the soil behind them to the treetops to ensure that the trees will not die because of photosynthesis dehydration. But now that your tree has no roots, there is no way to absorb less water from the soil to support it. When you stop planting trees, you should try to keep the water in the trees. It is best to wrap the broken part with plastic film at the branch removal place, which will help the trees not die of water loss before taking root! When sowing, the soil moisture should not be too much or too dry. The best thing to do is to go outside and dig with you. Plant small trees, compact the surface, and then water them until the water penetrates under the flowerpot. Then put the flowerpot in a sunny place. After planting, water once a week when the current air humidity is greater than 80 {BF}. If it is between 50 {BF} and 80 {BF}, you can choose to water it once every three days to once a week. Watering shall be based on the seepage at the bottom of the flowerpot. You water so much every day, I think the roots may all be dead, but you'd better not water so much first, and wait for a week or two to see if the young tree is still alive. Of course, you can spray the leaves on the epidermis of the tree with a shower every day, but don't spray the soil!
