Pick up some "black skin" to grow flowers
In the process of plant maintenance, fertilization is a key link in determining the health of flowers. Although commercially available fertilizers are convenient, natural materials are not only economical and environmentally friendly, but also provide total nutritional support for plants. This article reveals the wonderful uses of three special "black skins", turning common waste into flower cultivation artifacts. 1. Willow bark: The natural growth promoter salicylic acid activates the root system. The exfoliated epidermis of willow trees on the river bank contains 0.8%-1.2% salicylic acid. This plant hormone can promote cell division and accelerate the development of capillary roots. In winter, it is advisable to select gray-brown old skin to avoid new and tender skin carrying eggs. After the deep fermentation process is exposed to the sun for 3 days, the bark is chopped to a size of 2 cm and mixed with rice washing water in a ratio of 1:3. Open the lid every week during the sealed fermentation period, and use the clarified solution 50 times with water after 60 days, which can enhance the disease resistance of roses and orchids. 2. Pine bark: Ventilation experts physically improve the unique scale structure of the substrate pine bark can increase the soil porosity by 30%, which is especially suitable for succulent root plants such as succulent and clivia. Before use, it needs to be steamed at high temperature for 20 minutes to decompose turpentine residues. Layered application techniques Large pieces of bark pad the bottom of the basin as a drainage layer, and medium-sized fragments are mixed into the matrix, and the powder form can moisturize the pavement. 1:1 ratio with perlite can significantly reduce the incidence of root rot. 3. Plant ash: All-round nutrient source Pick up a treasure house of trace elements for "black skin" flower cultivation Plant ash contains 5%-10% potassium oxide and calcium, magnesium, iron and other elements. A pH value of 8-9 can neutralize acidic soil. It is recommended to use broad-leaved plants to burn ashes, and pine needle ash contains oil and must be used with caution. Scientific application plan Mix soil at a ratio of 5% for sterilization before sowing, and sprinkle a 2cm thick ash layer every month during the growth period. Be careful to avoid mixing it with nitrogen fertilizer, which needs to be applied at an interval of more than 10 days.
The three types of black skin materials have their own characteristics: willow bark focuses on promoting growth, pine bark improves breathability, and plant ash supplements trace elements. Reasonable combination can increase soil activity by 40% and reduce the incidence of yellow leaves. It is recommended that flower lovers establish personalized formulas based on plant characteristics and regularly rotate materials so that natural gifts can achieve healthy plants.
