What kind of fertilizer is used to fertilize plum blossoms
As the first of traditional famous flowers, the nutrient supply during plum maintenance directly affects the flowering quality and cold resistance. Scientific fertilization not only requires selecting the right type of fertilizer, but also mastering the changing laws of growth cycles and nutrient needs. This article will systematically sort out the applicable fertilizer ratios and application techniques at different growth stages to help flower friends establish a year-round fertilization schedule. Selection and application principles of plum fertilizer. Key points for basal fertilizer application When planting, sufficient basal fertilizer must be applied at the bottom of the basin. The best choice is sheep manure that has been decomposed for 3 months. It has a balanced ratio of nitrogen, phosphorus and potassium and is rich in organic matter. When applying base fertilizer after flowering every year, it is recommended to mix 20% pine needle soil to improve the soil structure. Pay attention to maintaining a 5 cm distance between the fertilizer layer and the root system to avoid direct contact and causing root burning. Topdressing cycle management Apply sesame cake fertilizer water (1:50 dilution) during the new shoot growth period from February to March, and replenish it every 15 days to promote the development of branches and leaves. In June, fish sausage fertilizer + bone meal (3:1 mixture) was used during the flower bud differentiation period, and potassium dihydrogen phosphate (800 times solution) was poured every week. Nitrogen fertilizer application will be stopped from September, and plant ash will be buried every month to enhance lignification. Seasonal fertilization operation details Spring germination management When the temperature stabilizes above 12 ° C, fermented rapeseed cake and humus soil are used to make nutrient soil at a ratio of 1:3, and the surface is covered and mixed with EM bacterial solution. Pay attention to observe the unfolding of new leaves. If yellowing occurs, ferrous sulfate solution should be replenished in time to adjust the pH value. Summer fertilizer control skills During the high temperature period, the principle of "thin fertilizer and frequent application" is adopted, and traditional liquid fertilizer is changed to slow-release granular fertilizer. It is recommended to use Ao Lu 318s formula fertilizer, and embed 20 grains along the edge of the pot to meet the nutrient requirements for three months. Special attention should be paid to drainage in the rainy season, and all fertilization operations should be suspended in case of accumulated water. During the autumn and winter transition period, the last topdressing is carried out in late October, and bone meal mixed with rice hull charcoal (2:1) is applied circumferentially along the edge of the pot. In the northern region, anti-freezing nutrient solution (containing seaweed extract and fulvic acid) is watered before winter, and in the southern region, brassin can be sprayed monthly on the leaves to enhance stress resistance.
A reasonable fertilization system needs to be coordinated with dynamic adjustment of plant growth. It is recommended to record branch growth and new leaf color changes every month, and optimize fertilization plans based on regional climate characteristics. Through observation and adjustment of a complete three-year growth cycle, a personalized plum blossom maintenance plan can be formed.
