How to make gardenia grow buds
Gardenia is famous for its rich fragrance, and the development of flower buds directly affects the quality of flowering. Mastering scientific maintenance skills can keep gardenia full of vitality from germination to blooming. This article will explain in detail the key points of the entire cycle of flower bud cultivation through a combination of pictures and texts. The three major factors that promote flower bud formation are photosynthetic energy reserves. Late spring and early summer are the critical period for flower bud differentiation of gardenia. It is recommended to ensure 6 hours of scattered light irradiation every day. South-facing balcony or under the shade of a tree is an ideal place. During strong light periods, you can use a sunshade net to filter 30% of the light. Shaping pruning strategy: Puncturing treatment from March to April to retain 5 pairs of leaves to promote secondary branches. Leave a 45-degree oblique incision when thinning dense branches, and spray carbendazim immediately after pruning to prevent infection. Accurate nutrition supply alternating use of potassium dihydrogen phosphate (1:1000) and decomposed soybean cake water every 10 days before buds appear. The humidity of the substrate is maintained at about 60%, which can be detected by using the bamboo stick insertion method: the bamboo stick brings out the micro-humid soil without watering. Five key points for flower bud maintenance are scientifically controlled during the flower bud expansion period. The "see dry and see wet" method is used, and the surface 3 cm soil is dried before being poured thoroughly. The air humidity is maintained at 65%-75%, which can be achieved by padding wet pebbles with trays. The fertilizer was finely proportioned and the application of nitrogen fertilizer was stopped after the buds were sprouted, and the special slow-release fertilizer for flowers was used (NPK=5:15:45). Spray boric acid solution (0.1%) on the leaves every month to enhance the load-bearing capacity of the flower stalk. Light intensity adjustment The light needs to be enhanced during the flower bud coloring period, but direct light needs to be avoided at noon. Using a sunshade net with a shading rate of 40% can prevent sunburn and ensure color saturation.
In addition, it is necessary to pay attention to controlling the temperature difference between day and night at 8-10 ° C, and rotating the flowerpot regularly to ensure uniform light reception. It was found that aphids were promptly controlled and controlled with matrine biological agents to maintain good ventilation in the environment.
It takes about 45 days from flower bud differentiation to bloom. The principle of "promoting before and controlling after" is followed: strengthening nutrient accumulation in the early stage and focusing on environmental regulation in the later stage. Record the maintenance log and observe the development status of flower buds. You will be able to harvest flowers full of trees.
