Detailed Explanation of Edible Mushroom Cultivation Techniques and Flower Fertilization Methods

As people's living conditions improve, almost every household grows some flowers and plants at home. To make these flowers bloom beautifully, you should understand their habits and master their fertilization methods. So how should flowers be fertilized? Today, the editor will share with you what the commonly mentioned "three looks" of flower fertilization refer to.

First, look at the season. In winter, temperatures are low and plant growth is slow. Most flowers are in a state of suspended growth and generally are not fertilized. Spring and autumn are peak growth periods for flowers, when roots, stems, and leaves grow, flower buds differentiate, and young fruits swell, all requiring more nutrients, so more topdressing should be applied appropriately. In summer, temperatures are high and water evaporates quickly, and it is also a period of vigorous growth for flower plants, so the concentration of topdressing should be lower and the frequency can be higher. At the seedling stage, more nitrogen fertilizer can be applied to promote rapid and robust seedling growth. At the bud stage, more phosphorus fertilizer can be applied to promote larger flowers and plump seeds. At the early fruit-setting stage, fertilization should be appropriately controlled to help fruit set.

Second, look at the variety. Different varieties of flowers have different fertilizer requirements, so different fertilizers should be applied. For example, osmanthus and camellia prefer pig manure and should avoid human feces and urine. Southern flowers such as rhododendron, camellia, and gardenia should avoid alkaline fertilizers. Flowers that need heavy pruning every year require a higher proportion of phosphorus and potassium fertilizer to promote the sprouting of new shoots. For foliage-oriented flowers, fertilization can focus more on nitrogen fertilizer. For flowers with large blooms, such as dahlia and chrysanthemum, an appropriate amount of complete fertilizer should be applied during the flowering period so that all flowers can open and be beautiful in shape and color. For fruit-oriented flowers, water should be appropriately controlled during the flowering period, and sufficient complete fertilizer should be applied during the fruit-swelling stage to achieve the expected results. For bulbous flowers, more potassium fertilizer should be applied to help the bulbs become plump. For fragrant flowers, applying more phosphorus and potassium fertilizer when they enter the flowering period can promote a stronger fragrance.

Third, look at the growth condition. Especially for potted flowers, fertilization should be based on growth condition to determine the amount. Adhere to the principle of "four more, four less, four no," namely: apply more when yellow and thin, apply more before germination, apply more at the bud stage, and apply more after flowering; apply less when robust, apply less at germination, apply less when flowering, and apply less during the rainy season; do not apply when growth is leggy, do not apply when newly planted, do not apply in the height of summer, and do not apply during dormancy. At the same time, attention should be paid to the "four taboos": first, avoid concentrated fertilizer; second, avoid raw fertilizer (organic fertilizer must be fully decomposed before use); third, avoid hot fertilizer (in summer at noon, soil temperature is high, and fertilizing easily damages roots); fourth, avoid sitting fertilizer, that is, when planting flowers, do not place the roots directly on the base fertilizer at the bottom of the pot. Instead, add a layer of soil on top of the fertilizer, and then plant the flowers into the pot.
