Full-light Spray Cutting Seedling Technology Application in Flower Cultivation
This article provides a detailed introduction to the aspects of home flower cultivation, focusing on the application of full-light spray cutting seedling technology in flowers, and will further explore with everyone.
For many high-value, difficult-to-root superior flower varieties, the conventional cutting seedling methods not only consume a lot of manpower and resources but also have slow propagation rates, low survival rates, and insufficient supply. In order to improve the cutting survival rate and reduce flower costs, we have adopted the full-light spray cutting seedling technology, effectively solving the problem of difficult rooting in flower varieties, with a survival rate of over 95%. It also shortens the flower cultivation cycle for mass production, yielding considerable economic benefits. The specific practices are summarized as follows:
1. Establishment of Cutting Beds and Equipment Installation
The cutting beds should be set up in flat terrain with good ventilation, sufficient sunlight, convenient drainage, and close proximity to water and power sources. A circular cutting bed with a radius of 0.6m and a height of 40cm, higher in the middle and lower on the sides, should be made. A drainage outlet is left every 1.5m at the bottom, and a full-light automatic intermittent spray device imported by the Technology Information Center of the National Forestry Bureau is installed at the center of the cutting bed. The device consists of a leaf moisture controller and a symmetrical double-long-arm circular scanning spray mechanical system. Under the cutting bed, 15cm of cobblestones are铺ed, and 25cm of river sand is铺ed on top. Before cutting, the cutting bed is sprayed and disinfected with a 0.2% potassium permanganate solution or a 0.01% solution of carbendazim.
2. Cutting Time
From late May to mid-September.
3. Cutting Varieties
Clerodendrum, Jasmine, Michelia, Ficus elastica, Begonia, Fructus, Rose, Chrysanthemum, Celosia, Marigold, and other more than 10 kinds of woody and herbaceous flowers.
4. Cutting and Treatment of Cuttings
For woody flower cuttings, the semi-woody tender branches of the current year with leaves are used as cuttings. For herbaceous flower cuttings, the tender stems with leaves are used as micro-cuttings. When cutting the cuttings, the too tender top part of the new shoots is first removed, then cut into cuttings 8-10cm long, leaving more than 2 buds on the top, and the leaves on the cuttings are pruned. Larger leaves only need to leave one or fewer, the leaf area of the cuttings is generally left at about 10 square centimeters, smaller leaves are left with 2-3, with a flat top cut and a slightly oblique bottom cut, bundled in 50. Before cutting, the cuttings or their bases are soaked in a 0.01%-0.125% carbendazim solution, then quickly dipped in a 1,000x10" ABT rooting powder for treatment.
5. Cutting and Post-cutting Management
The cutting depth is 2-3 cm, and the cutting density is 400-500 plants per mu. After cutting, water thoroughly immediately, and spray a 0.01% carbendazim solution early in the morning or evening the next day to prevent infection and disease. After that, spray once every 7 days. When roots begin to grow, a 0.1% potassium dihydrogen phosphate solution can be sprayed. After the roots have grown, the concentration of potassium dihydrogen phosphate can be increased to 1% to promote木质化 of the roots. At the same time, withered leaves on the seedbed should be cleared at any time.
Using this technology for seedling cultivation, Clerodendrum, Jasmine, and Michelia begin to root after 25-30 days, with a rooting rate of over 90%. Ficus elastica, Fructus, Rose, and Begonia begin to root after 15-20 days, with a rooting rate of over 95%. Chrysanthemum, Celosia, Marigold, and others begin to root after 7-10 days, with a rooting rate of over 98%.
6. Transplanting
The best time for transplanting is after 5:00 PM and before 10:00 AM, or all day in cloudy weather. To improve the survival rate of transplanting, stop watering 3-5 days before planting to harden the seedlings. Seedlings should be transplanted immediately after digging. After transplanting, place the flowerpots under a shade net and water for the second time after 7 days, and gradually move them to sunlight for daily management and cultivation after 15 days.
Full-light spray cutting seedling technology is a new type of seedling cultivation technology with low investment, quick results, high automation, easy to operate, saving labor, saving land, high seedling survival rate, high propagation coefficient, and short seedling cultivation period. It is a good method for rapid seedling cultivation and is very suitable for widespread promotion and application in the flower industry.
