Common Methods of Using Chemical Fertilizers for Home Gardening
A comprehensive explanation of the relevant experience of fruits and vegetables, the common methods of using chemical fertilizers for home gardening, let's understand together next.
Common Methods of Using Chemical Fertilizers for Home Gardening
(1) Nitrogen Fertilizers: Common fertilizers include urea, ammonium sulfate, and ammonium nitrate, which are the main sources of fast-acting nitrogen supply and one of the main elements for plants to synthesize proteins. When used, they can be prepared into a solution with a concentration below 0.1%, and an excess can cause plant dehydration and death.
(2) Phosphate Fertilizers: Calcium superphosphate and phosphate rock powder are sources of phosphorus, which help flower bud differentiation, strengthen plant roots, and increase plant cold resistance. Their fertilizer effect is slower, and they are less commonly used in pot culture of flowers, where phosphorus is often obtained through compound phosphorus fertilizers. When using calcium superphosphate as top dressing, first dilute it with 50-100 times water, soak overnight, and then pour the clear liquid on top.
(3) Potassium Fertilizers: Potassium is a major element of plant ash and can enhance plant resistance and disease resistance, making it an indispensable element for plants. Common potassium fertilizers include potassium chloride and potassium sulfate, which can be prepared into a solution with a concentration below 0.1% for top dressing.
(4) Compound Fertilizers: There are many types of compound fertilizers, which refer to chemical fertilizers containing nitrogen, phosphorus, and potassium or any two of these elements. Common ones include monopotassium phosphate, Russian compound fertilizers, diammonium phosphate, etc., which can be prepared into a water solution with a concentration of 0.1% to 0.2% for top dressing. Recently, fertilizer manufacturers have also launched some flower-specific fertilizers, such as foliage plant-specific fertilizers, woody plant-specific fertilizers, herbaceous plant-specific fertilizers, acidic soil-specific fertilizers, cactus-specific fertilizers, and bonsai-specific fertilizers, which are available in the flower market and can be used as instructed.
(5) Trace Elements: Trace elements are required in small amounts during plant development, and the trace elements in the soil are usually sufficient for the growth of flowering plants. However, some plants may show symptoms of chlorosis, leaf spots, etc., due to a lack of trace elements during growth. For example, iron deficiency in flowers manifests as chlorosis; boron deficiency as the cessation of apical growth, dwarfing of the plant, and reduction in leaf size; zinc deficiency as chlorosis and small leaf disease, etc. Application concentrations: foliar spray concentration for boron fertilizers is 0.1% to 0.25%, zinc fertilizers 0.05% to 0.2%, molybdenum fertilizers 0.02% to 0.05%, iron fertilizers 0.2% to 0.5%, and manganese fertilizers 0.05% to 0.1%.
The above information covers all the common methods of using chemical fertilizers for home gardening. Green plant enthusiasts may refer to this for reference.
