1, lemon making nutrient solution
Irrigation with water containing citric acid in soil can change the properties of soil, increase the acidity of soil and promote the absorption of iron by plants, thus making plants grow healthier. Prepare a few fresh slices of lemon, four spoonfuls of white vinegar and a pot of cold water. Add the lemon slices and white vinegar into the cold water and stir well. Let it stand overnight, and the homemade citric acid will be ready!
It is said that this homemade citric acid can not only water the flowers, but also wash the kitchen utensils with a rag dipped in water, which can effectively remove stains! Watering the flowers is also very simple. Take out 10 ml each time, add it into 1 liter of water, stir and mix, and then use it on plants!
2, carbonated drinks to make nutrient solution
The reason why plants like to drink carbonated drinks is actually very simple. The ingredients of carbonated drinks also contain citric acid, which can promote the growth of plants. So don't waste any unfinished carbonated drinks in the future! Just use it to make nutrient solution and water the flowers!
The proportion of carbonated drinks as nutrient solution is similar to that of the first method. Four spoonfuls of carbonated drinks and a basin of water are stirred evenly and left standing for about half a week, then they can be used to water the flowers!
Matters needing attention in the use of plant nutrient solution:
1, culture medium
Plant nutrient solution can be used as the culture solution of hydroponic plants, because it is rich in nutrients and can provide nutrients needed for plant growth. When hydroponics plants, it is best to change the culture solution every 10 day, and pay attention to the concentration of plant nutrient solution should not be too large.
2, foliar fertilizer
When planting foliage plants, it is necessary to prepare a plastic sprayer or glass bottle and fill it with plant nutrient solution. After diluting the water, spray it on the leaves of plants to make them greener and brighter. The nutrient solution prepared on the same day needs to be used up to avoid reducing fertilizer efficiency.
