Full light spray propagation technique applied to flower planting
An article on green plant knowledge, introducing the knowledge of flower propagation. The application of full light spray propagation technique in flower planting is specifically introduced as follows:
For many high-value flowers that are difficult to root, the basic cutting propagation method not only consumes a lot of manpower and material resources but also has a slow breeding speed, low survival rate, small quantity, and high demand. In order to improve the survival rate of cuttings and reduce the cost of flowers, we adopt the full light spray propagation technique, which effectively solves the problem of difficult rooting in flower species, achieves a survival rate of over 95%, and also shortens the flower cultivation cycle for mass production, resulting in significant economic benefits. The specific practices are summarized as follows:
1. Establishment and installation of the cutting bed
The cutting bed should be built in an area with flat terrain, good ventilation, sufficient sunlight, convenient drainage, close to water resources, and power supply. A circular bed with a diameter of 6m and a height of 40cm, higher in the center and lower on the sides, should be made. An outlet is left every 1.5m at the bottom, and a full light automatic intermittent spray device introduced by the Science and Technology Information Center of the State Forestry Administration is installed at the center of the bed. The device consists of a leaf moisture controller and a symmetrical double Excavator with extended arm circular scanning spray mechanism. The bed is铺ed with 15cm of cobblestones and 25cm of river sand, and before planting, the bed is disinfected by spraying 0.2% potassium permanganate or 0.01% triazole solution.
2. Cutting time
From late May to late September.
3. Types of cuttings
Over ten kinds of woody and herbaceous flowers such as bougainvillea, jasmine, Madrid, happy tree, Spanish begonia, hibiscus, roses, chrysanthemums, scarlet sage, marigolds, and snapdragons.
4. Cutting and treatment of scions
For woody flower cuttings, use the current year's semi-woody branches with leaves as scions, and for herbaceous flower cuttings, use the tender stems with leaves as micro-scions. When cutting scions, first remove the too tender tip part, then cut scions 8-10 cm in length, leaving two or more buds at the top, and trim the leaves on the scions. For large leaves, only one or fewer leaves are left, generally leaving 10-12 leaf area indices for scions with large leaves, 2-3 leaves for smaller ones, ensuring a flat top cut and a slightly slanted bottom cut, bundled in 50. Before planting, soak the scions or their lower parts in 0.01%-0.125% triazole solution, then quickly dip the tip in 1000x10" ABT root powder for treatment.
5. Planting and post-planting management
The cutting depth is 2-3 cm, with a density of 400-500 plants per mu. After planting, immediately spray a thorough watering, and in the morning or evening of the next day, spray 0.01% triazole solution to prevent disease. Every 7 days, spray once. When the roots start to grow, spray a 0.1% potassium dihydrogen phosphate solution. After rooting, the concentration of potassium dihydrogen phosphate can be increased to 1% to promote木质化 of the stems. Also, remove withered leaves and branches around the bed at any time.
Using this technique, bougainvillea, jasmine, and Madrid begin to root after 25-30 days, with a rooting rate of over 90%. Happy tree, hibiscus, roses, and Spanish begonia begin to root after 15-20 days, with a rooting rate of over 95%. Chrysanthemums, scarlet sage, marigolds, and snapdragons root after 7-10 days, with a rooting rate of over 98%.
6. Planting
The planting time should be after 5:00 PM or before 10:00 AM, and it can be planted 24 hours after a rainy day. To improve the survival rate of planting, stop watering for 3-5 days before planting to harden the seedlings, and plant them immediately after digging. After planting, place the potted plants under a sunshade net and water them for the second time after 7 days, then gradually move them to the sun for daily management and cultivation after 15 days.
The full light spray propagation technique is a new type of planting technology with low investment and good results, high automation level, easy to operate, saving time and space, with high seedling rate, high propagation coefficient, and short propagation cycle. It is a rapid propagation method, very suitable for wide application and promotion in the flower industry.
