Edible rose, as its name implies, is a rose used to produce processed food. From this point of view, I think the most important thing is to focus on environmental protection and pollution-free, and on this basis, improve the output per unit area of edible roses. Key points of cultivation and management of edible roses: 1. Stay away from or avoid the pollution sources of the external environment: pay attention to this when choosing rose planting plots. If your current planting plot is in a polluted environment, it is recommended to move. Second, reduce the pollution of chemical fertilizers and pesticides and the accumulation of residual poison: pay attention to the selection of farm manure and organic manure when applying fertilizers, and match them with appropriate mineral fertilizers and trace fertilizers such as phosphorus and potassium according to the soil detection situation to meet the needs of the growth and development of roses, and cultivate soil with weak PH value in combination with soil improvement; Regarding the prevention and control of pests and diseases, prevention should be given priority to and combined with prevention, and artificial prevention and control and pollution-free biological organic pesticides should be adopted. Third, the arrangement and pruning of plant rows: the arrangement of plant rows should be north-south and the spacing between plants should be appropriate, which is convenient for ventilation, light transmission and flower picking of rose bushes. Plastic pruning: generally carried out in winter and spring, cutting off branches of diseases and insect pests, old and weak branches and too dense branches, and renewing and rejuvenating them in time. The number of branches between plants and within plants is appropriate (ventilation and light transmission), which is convenient for daily management and flower picking in the field. Fourth, protect the leaves: edible roses are generally concentrated in May-June, and there is still a long growth time from flower picking to defoliation. The formation of rose yield and quality in the coming year mainly depends on the photosynthetic products made by leaves during this period. 5. timely topdressing base fertilizer and foliar spraying fertilizer: base fertilizer is generally applied after autumn every year. When applying fertilizer, try not to hurt the roots or less. If the main root is injured, the wound should be trimmed and the stubble should be smooth and tidy. Spraying foliar fertilizer: Generally, it is applied twice a year, once about half a month before picking flowers and once about half a month after picking flowers. 6. Strengthen daily field management: Rose is cold-resistant, drought-resistant, barren-tolerant, and simple in management. It is mainly to detect fertilizer supply, pests and diseases, and whether there is water shortage, handle and solve the situation in time, and strengthen daily field management such as weeding and drainage in rainy season. Seven, timely picking flowers (buds): roses are usually picked in the morning, and should be picked in time according to different purposes or the standard requirements of buyers. Big flowers and small flowers will affect the yield and quality of roses. After picking flowers, handle them in time, or send them to buyers in time, so as to minimize the natural volatilization of rose fragrance components, reduce the weight and affect the income of growers.
