The role of ferrous sulfate The application method of ferrous sulfate Potted lemons are loved by many plant lovers because of their fresh aroma and rich nutritional value. It is not easy to make potted lemons grow healthily. Reasonable use of ferrous sulfate is the focus of many growers. This article will deeply analyze the role of ferrous sulfate in the maintenance of potted lemons and help you grow healthy and beautiful lemon trees. Effect of ferrous sulfate Ferrous sulfate is a commonly used trace element fertilizer. Its main component is iron. Iron is an indispensable trace element during plant growth and plays an important role in the growth and development of potted lemons.
1. Prevent and improve yellow leaf phenomenon In potted lemons, yellow leaf phenomenon is prone to occur during the growth process. This is because iron in the soil is insufficient, which causes the leaves to fail to perform normal photosynthesis. Ferrous sulfate can supplement the iron in the soil. Effectively prevent and improve the yellow leaf phenomenon.
2. Promote plant growth Iron is an important component in plants synthesizing chlorophyll. Chlorophyll is a key substance for plants to carry out photosynthesis. The supplement of ferrous sulfate helps to improve the synthesis of chlorophyll, thereby promoting plant growth.
3. Enhance plant disease resistance Ferrous sulfate can also improve plant disease resistance and make potted lemons healthier. Application method of ferrous sulfate After understanding the role of ferrous sulfate, we still need to master the correct application method to ensure the healthy growth of potted lemons.
1. Measuring soil pH Before applying ferrous sulfate, the pH of the soil needs to be measured first, because ferrous sulfate works better in acidic soil, but may have adverse effects in alkaline soil.
2. Prepare ferrous sulfate solution and dissolve ferrous sulfate in water according to a certain proportion to make ferrous sulfate solution. Dissolve 1 gram of ferrous sulfate per liter of water.
3. Regularly spray the prepared ferrous sulfate solution evenly on the leaves of potted lemons, spraying it 1-2 times a week. Pay attention to avoid direct contact with the solution with the fruit when spraying, so as not to affect the quality of the fruit.
4. Pay attention to the amount of fertilizer applied and the amount of ferrous sulfate should not be too much. Too much may lead to excessive iron in the soil, thus affecting plant growth. The total amount of ferrous sulfate applied per pot of lemon per year should not exceed 50 grams.
Ferrous sulfate plays an important role in the maintenance of potted lemons. By correctly applying ferrous sulfate, it can effectively prevent and improve the yellow leaf phenomenon, promote plant growth, and enhance plant disease resistance. I hope the introduction in this article can help you raise healthy and beautiful potted lemons.
