Embodiment 1

[0047] 1. Arch shed preparation: use ordinary steel pipe arch shed with a span of 8m, a shed shoulder height of 1.5-2m, and a top height of about 3m. Cover the top with 8-silk film in winter, and install upside-down micro-spraying in the shed; keep the temperature in the shed between 20 and 26 °C.

[0048] 2. Substrate formula and preparation for rapid propagation: The matrix formula is: perlite: vermiculite: grass carbon = 1:1:1. The diameter of perlite is 1-3mm, that of vermiculite is 2-4mm, and grass carbon is high-quality grass carbon. Mix the substrate in proportion before cutting, and keep the substrate away from rain before use.

[0049] 3. Preparation of rooting solution: 1g potassium indolebutyrate + 0.25g sodium naphthalene acetate mixed with 1.25kg water for 5 seconds, potassium indolebutyrate and sodium naphthalene acetate are dissolved in alcohol first.

[0050] 4. Preparation of leaf nutrient solution: Potassium indolebutyrate 1g / 80kg water + sodium naphthalene...

[0058] 1. Arch shed preparation: use ordinary steel pipe arch shed with a span of 8m, a shed shoulder height of 1.5-2m, and a top height of about 3m. Cover the sunshade net with a shading rate of about 75% in summer. Install upside-down micro-spraying in the shed; keep the temperature in the shed between 20 and 26°C.

[0059] 2. Substrate formula and preparation for rapid propagation: The matrix formula is: perlite: vermiculite: grass carbon = 1:1:1. The diameter of perlite is 1-3mm, that of vermiculite is 2-4mm, and grass carbon is high-quality grass carbon. Mix the substrate in proportion before cutting, and keep the substrate away from rain before use.

[0060] 3. Preparation of rooting solution: 1g potassium indolebutyrate + 0.25g sodium naphthalene acetate mixed with 1.25kg water for 5 seconds, potassium indolebutyrate and sodium naphthalene acetate are dissolved in alcohol first.

Embodiment 3

[0069] The current common cutting method of orange rootstock is: mainly in winter or early spring, select mature spring shoots, summer shoots and autumn shoots as cuttings, cut cuttings with a length of 15-20cm, leave no leaves, and insert them into sterilized In the fine river sand, the water content of the river sand is about 60%. Use the river sand to make a cutting box with a width of 1.5m and a length of about 10m. When cutting, leave 1 bud on it. Cuttages are carried out at a density of 15cm between rows and 2cm between plants, and then use The white mulch is tiled to keep moisture, and the shed is covered. Generally, germination begins after 20 days, rooting begins after 30 days, and transplanting begins after 60 days. The rooting rate is about 82%, but the roots are mostly taproots, and the rooting amount is small. Each cutting takes 2 to 5 roots, with 3 in the majority. The transplanting survival rate is 76%, and the growth after transplanting is not good.

Abstract

The invention discloses a rapid cultivation method of an orange rootstock. The method comprises the following steps: cutting branches from a strongly-growing healthy orange tree without diseases and insect pests, and cutting the branches into small cuttings with leaves; performing soaking disinfection treatment on the cut small cuttings, and washing the small cuttings with clear water to drain water; quickly dipping the lower parts of the disinfected small cuttings which are just drained by using a rooting solution for 3-6 seconds, and then performing cuttage immediately on the small cuttings into a hole tray filled with a substrate; carrying out water spraying treatment on the substrate in the hole tray before cuttage, enabling the humidity of the substrate to be 70%-85%, conducting water spraying treatment after cuttage is completed, and then conducting management after cuttage. The rapid cultivation method of the orange rootstock provided by the invention can be carried out at normal temperature and under common facilities, the rooting quantity is extremely large, the propagation coefficient is high, and nursery stocks grow fast and are stable in character after being transplanted.

Description

technical field [0001] The invention relates to the technical field, and more specifically, relates to a rapid cultivation method for orange rootstocks. Background technique [0002] Yuzu belongs to the Rutaceae family and is a small tree of the genus Citrus, which grows well in alkaline soil. The branches usually have thick and long thorns, and the new shoots and young petioles are often thinned and short-haired. Leaves are thick and papery, wing leaves are obovate-elliptic, round or blunt at the top, tapering to the base, cuneate, ovate or lanceolate, round or blunt at the base, flowers solitary in leaf axils, drooping, short pedicel Calyx cup-shaped; petals white, fruit oblate or nearly pear-shaped; seeds many, broadly ovate, plump, single or multiple embryos. Flowering in April-May, fruit picking in October-November. [0003] In recent years, due to the rapid development of hybrid citrus in my country, yuzu has also become a rootstock variety favored by fruit growers....
