How to conduct rose dressing
Luoyang Wang of Henan Province asked how the top dressing should be conducted. What problems should be paid attention to when fertilizing? A: After the Chinese rose is cultivated, different fertilizers will be applied according to the characteristics of the fertilizer required in different periods. After germination in the spring and before winter, 20-25 cm around the tree, combined with shallow tillage grass or irrigation, applied into the decomposed human and animal manure water, chemical fertilizer solution or dry chemical fertilizer. 2 to 3 times a month, 40 to 50 grams of chemical fertilizer per plant. The proportion of N, P and K in fertilizers is dominated by nitrogen and phosphorus before flowering, phosphorus and potassium are dominant after flowering, and nitrogen fertilizer cannot be used in autumn, otherwise it will affect safe wintering. For example, the proportion of fertilization formula for flowering is 1 kg urea, 2 kg superphosphate, 2 kg potassium sulfate, and 0.2% fertilizer solution after mixing. It is also possible to use high-nitrogen-potassium-type compound fertilizers, and the foliar fertilizer concentration is generally not more than 0.2%. Spray in sunny mornings or evenings, avoiding sunny noon and rainy days, once every 7-10 days. Be careful not to apply fertilizer to flower buds, flowers or leaves. Do not apply fertilizer after flowering and just pruning. It is best to apply it during the two flowering periods.
