(3) Managing the cutting before rooting: controlling the temperature in the greenhouse to be below 25 ℃, avoiding direct irradiation of strong light and keeping the moisture content in the soil;
(4) And (3) maintenance management after rooting of the cutting strips: when the cutting shoots sprout, using quick-acting compound fertilizer to dilute 600-1000 times for foliage spraying, and keeping the greenhouse in a ventilation state;
(5) Planting and seedling stage management:
transplanting: transplanting rooted cutting strips into a greenhouse of a seedling nursery at the beginning of the middle and last ten days of spring 2-3 months, wherein the row spacing of the seedlings is 40-50cm, watering sufficient root fixing water periodically after transplanting, shading, providing natural illumination after seedlings of the cutting strips survive, and keeping the greenhouse in a ventilated state;
watering, fertilizing and weeding: after transplanting, before the end of 5 months, keeping the soil moist, applying fertilizer, keeping the soil in a relatively dry state from the beginning of 6 months to the beginning of 9 months, spraying water once every 2-3 days at the evening to moisten the surface layer of the soil by 1-2cm, and keeping the soil moist and weeding during 9-10 months;
(6) Pinching: after seedlings of transplanted cutting strips survive, pruning at branch points at the lowest ends of the cutting strip plants, sending out a plurality of new branch strips at positions to be pruned after pruning, pinching off tender shoots at the top ends of the branch strips when the new branch strips grow to 3-4cm, completing primary pinching, repeating the pinching until the crown width exceeds 10cm, selecting branches on the outer circle of the plants for pinching, and cutting the cutting branches to keep a certain height.
Preferably, the mixing weight ratio of the garden soil, the perlite and the turf in the matrix preparation in the step (1) is (3-5): (0.5-1.5):1.
Further, the mixing weight ratio of garden soil, perlite and turf in the matrix preparation in the step (1) is (3-5): 1:1.
Preferably, when watering in the step (1), sterilizing liquid is added into water, and the substrate is watered thoroughly.
Preferably, the sterilization solution is selected from one or more of thiophanate methyl solution, sodium dichloroisocyanurate solution and silver ion composite solvent.
In order to improve the growth cycle time of the cutting and shorten the seedling cycle time, the applicant finds that garden soil, perlite and grass carbon are mixed according to the ratio of (3-5): (0.5-1.5) and (1) in a weight ratio of (3-5): 1:1, adding the sterilizing liquid into water to sufficiently irrigate the water, so that the water permeability, air permeability and water content of the substrate can be improved, and the substrate has sterilizing property, probably because perlite has a certain porous structure to improve water permeability and air permeability, the substrate cannot be in a humid environment, the water permeability and air permeability of the substrate are improved, and grass peat has a layered structure and can adsorb water, so that the problem of hardening and hardening of the substrate in a ventilated environment is solved, but the content of the grass peat cannot be too much, the content of humus in the substrate can be increased after too much, the breeding of bacteria at the shearing opening of the cutting slips can be easily caused, the rooting of the cutting slips is influenced, and the growth of the cutting slips is further influenced; the applicant finds in experiments that the problem that the growth of cutting slips is influenced by adding turf can be solved by adopting the bactericidal liquid in the matrix watering process.
Preferably, the selection and processing of the skewers in step (2): in autumn with the temperature not higher than 15 ℃, cutting healthy, thick and strong annual semi-lignified branches without flower bud differentiation, cutting the cutting slips at a position 8-10cm away from the top end, then cutting off the seedling tips, horizontally cutting, keeping the length of the cutting slips at 6-8cm, immersing the lower ends of the cutting slips in 50% of thiophanate methyl solution diluted by 800-1200 times for 40-90s, fishing out, placing in a shade for 10-20min, dipping the lower ends of the cutting slips in IBA solution with the concentration of 400-600 ppm, inserting into a substrate in a nutrition pot, and watering thoroughly to wrap the cutting slips and the substrate tightly.
The 50% thiophanate methyl is wettable powder with the dosage form of 50% thiophanate methyl.
The IBA is indolebutyric acid.
Managing the cuttage branches before rooting: controlling the temperature in the greenhouse to be below 25 ℃, avoiding direct irradiation of strong light and keeping the moisture content in the soil;
preferably, in the management before rooting of the cutting shoots in the step (3), the temperature in a greenhouse is controlled to be below 25 ℃, direct irradiation of strong light is avoided, too much water is not suitable, the soil is kept moist, and the leaves are kept in a stretched state. In the early stage of cuttage, a sunshade net is opened, a facility greenhouse is always kept in a ventilation state, and water is sprayed once every 15 pm to keep leaves in a fresh green state except in rainy days; in 7-10 days, the cuttage branches begin to be in a spread state, and then the cuttage branches are shaded in a sunny time period, and a greenhouse is kept in a ventilation state; and after the new roots are generated in 35-45 days, providing light for the cutting strips, reducing the watering amount to keep the seedbed matrix wet, and inducing more new roots.
In order to increase the number of the cutting shoot roots, the applicant finds that the number of the cutting shoot roots can be increased by controlling the wetting condition of the seedbed matrix and the illumination condition of the cutting shoot.
Preferably, the quick-acting compound fertilizer diluent is sprayed once within 5 to 10 days in the step (4).
