1、 Natural nutrient solution

Go under the deciduous trees in the garden and dig some flower soil to take home. Then put it into a basin, fill the basin with water, and gently stir it with a stick. Then put it under the sun and stir it again after its water and soil are layered. Wait until the water and soil are layered again, take out the supernatant from the upper layer and put it into a bottle for storage. These waters have the nutrients in the flower soil and are good nutrient solutions

2、 Rice washing water

When panning rice, take some clear liquid and put it into a bottle, and then tighten the bottle cap to keep the bottle sealed and airtight. After that, put it in the sun for about 15 days, pour the liquid into a basin, add 50 times the volume of clean water, and gently stir it evenly. Finally, put it in a bottle and save it. These water contain a lot of nitrogen and other nutrients, which is a good nutrient solution

3、 Compound fertilizer

Compound fertilizer can also be used to make nutrient solution. The specific method is to put it into water and stir it evenly with a wooden stick after it is completely dissolved. Then take it out and store it in a bottle. The water contains the nutrients originally contained in flower fertilizer, so it is also a good nutrient solution
