It is time for the spring to bloom. As the saying goes, spring is all year round. Flower growers are all looking forward to this year's flowers can bring substantial economic benefits. Well, it is very important to manage the field of flowers. Next, I will talk about what to pay attention to when fertilizing flowers. Experts pointed out that to do a “three look” in flower fertilization, which is the “three look”? The first is to look at the season. In winter, the temperature is low and plants grow slowly. Most flowers are in a state of stagnant growth and generally do not fertilize. In spring and autumn, it is a period of flower growth. Roots, stems and leaves grow, flower buds differentiate, and young fruit expands. Fertilizer, so it is appropriate to top-dressing; summer temperatures are high, the water evaporates quickly, but also a strong period of growth of flowering plants, so the topdressing fertilizer concentration is small, but the number can be more. The second is to look at the variety. Different varieties of flowers require different fertilizers, so different fertilizers should be applied. For example, like osmanthus, camellias like pig manure, do not like human excrement; rhododendron, camellia, gardenia and other southern flowers bogey alkaline fertilizer; flowers that need to be cut every year need to increase the proportion of phosphorus, potassium fertilizer, in order to facilitate the emergence of new branches; Flowers dominated by foliage can focus on nitrogenous fertilizers; flowers dominated by fruit should be given proper water control during flowering; bulbous flowers should be given more potassium to facilitate bulb filling. The third is to look at growth. Especially for potted plants, fertilization depends on the amount of growth. Adhere to the "four more, four less, four not" principle: more than four is: when the flowers appear more thin and thin, more than before germination, multiple buds when pregnant, after flowering more than Shi; four less is: less vigorous when applied, germination When the time is less, the flowering time will be less, and the rainy season will be less. Four is not: When the grower does not exercise, when the new planting time is not applied, it will not be applied during the summer heat and will not be applied when sleeping.
