Photinia fructus cutting propagation method
Choose a nursery: Drainage is good, the rain is only dry, the groundwater level is low, the transportation is convenient, the water source is abundant, or a single greenhouse is used, cover the greenhouse film (spring plug or autumn plug should also be covered with a membrane), plus shading net, use Ground seedbed, the ground is roughly leveled, the height difference between the center and the edge of the bed is less than 2cm.
Seedbed preparation: Set seedbed width 100cm, length is generally 20-30 meters, baffle around the seedbed, baffle height of about 12.
Substrate Preparation: Spread a layer of yellow earth (70-80%) on top, mix sand (20-30%) (sand particle diameter is less than 3mm), thickness is about 10cm, and the surface is leveled.
Seedbed disinfection: The seedbed surface is sprayed with 200 times potassium permanganate solution, and then the substrate is laid. After 24 hours, it can be cut.
Small arch film: Moso bamboo piece length 2m, width 2cm, small arch film width 2m, length depends on the length of the seedbed, the thickness of 4 silk.
Cuttings:
Time: Spring in early March, summer in early June, autumn in early September.
Spike cutting: The use of semi-woody shoots and lignification of the current year branches, cut into a leaf and a bud, the length of about 3.5cm, depending on the length of the leaves may be. Each blade retains half of the leaves, using a flat incision, the incision is smooth, and the incision is about 1 mm below the leaf blade;
Rooting agent treatment: cuttings of cuttings are treated with Zhoutianxiang root powder, formula: rooting agent 6g/bag, dissolve with 30ml alcohol, add 50ml warm water 60ml, clear water 1.4kg, yellow heart soil 5kg, etc. In small bundles, rooting agent mud. Pay attention to the strip moisturizing.
Density: Plant spacing 46cm, density 417/m2. After cutting, the leaves are not shaded.
Cutting: Should follow the cutting along with the cutting, try to shorten the time from cutting to cutting, the depth of 3cm is appropriate. After the cuttings are completed, they are immediately irrigated with water; the leaves are sprayed with a 1000-fold solution of carbendazim and anthraquinone-Fumei mixture, and a small arch shed is immediately erected, covered with a plastic film, sealed all around, and adhered to the film to cover 50% of the light transmittance. network.
Post-insert management:
Moisture and moisture management: One week after cutting, on a rainy or sunny morning or evening, the seedbed should be inspected. The moisture content of the matrix is ​​60-70% of the saturated moisture content, and the air relative humidity is more than 95%. After 15 days of cutting, some ears showed rooting. When most of the cuttings begin to grow roots, the moisture content of the substrate should be properly reduced, and it can be maintained at about 40% of the saturated moisture content. At this time, membrane ventilation can be gradually opened to reduce the matrix moisture content. When more than 50% of shoots sprout and new leaves are released, the film can be removed. During this period, care should be taken to keep the substrate moist.
Illumination and temperature management: After cutting with a monolithic greenhouse, in sunny days, especially in summer and autumn, shading nets should be placed on the small arch sheds, and the temperature in the small arch sheds should be controlled below 38°C. After cuttings, before rooting and germinating, they are basically shaded, and the shading rate is 75-90%; after all hairy roots and more than 50% of hair leaves, the small arch sheds are gradually removed and the shading net is removed.
Pest control: mainly anthrax and root rot, generally every 20 days, anthrax and carbendazim spray anthrax control, while the timely removal of diseased plants burned.
Nutrient management: Basic basal fertilizer is not used for cutting. After the hair roots were sprayed, water-soluble fertilizer (0.2% urea) was sprayed to promote the robust growth of cuttings.
Consolidation of seedlings: 20 days or so after the cuttings were introduced, observations of the germination situation of the new shoots were started, and the corresponding rooting conditions were observed. When more than 50% of the shoots are taken out of the shoots and new shoots are grown, the small shed film can be removed and the seedlings can be cultivated.
The plastic net including Plastic Flat Net, Plastic Slope Protection Net, slope greening vegetation net, plastic breeding fence net, plastic plant support net, plastic anti-bird/insect nets, plastic filter net, etc.
