Cutting Seedling technique of Pelargonium geranium

Geranium is a perennial herb or shrub, native to southern Africa, up to 1m high, stem upright, densely covered with shiny pilose, there are a variety of smells such as rose, citrus, mint, coconut and other fruit flavors, can be made into essential oils, common breeding methods for cuttage, hybrid seed sowing, tissue culture, the next small series to specifically talk about Geranium cuttage seedling technology.

1. Set up a female picking nursery of geranium geranium in a plastic greenhouse with good ventilation conditions and not easy to accumulate water. Set up a layer of manually opened and closed shading net with a shading rate of 50% in the greenhouse, and cover the ground of the greenhouse with black cloth.

2. Pelargonium delavayi female parent is planted in 15.5L flowerpots, placed in 2500 pots/mu of land, and the substrate is mixed with coconut bran: peat: pearlite in a volume ratio of 2:1: 0.5. 18-6-12 GAL-XEONE controlled-release fertilizer for trees and shrubs is applied to Aibei every 1m ³, and mixed with the substrate thoroughly and evenly.

3. Keep the highest temperature in summer below 35 ° C, the lowest temperature in winter above 6 ° C, the strongest light intensity controlled in the range of 30000-35000Lx, and open the sunshade net before 10:30 a.m. in spring and autumn and after 4:30 p.m. in summer. 3-10 The month is the growth period of geranium, watering once every 2 days, it should be noted that watering is stopped on rainy days, watering once every 4 days during the dormant period from November to February of the second year, fertilizing once every 2-3 months, and stopping fertilization during the dormant period from November to February of the second year.

4. Put the tray filled with substrate on the seedbed before cuttage, and disinfect the substrate with 1000-fold methyl thiophane 2 hours before cuttage.

5. In the first ten days of March, the tender stems of geranium plants in the female nursery shall be cut as cuttings with pointed pruning shears. Each cutting shall be provided with leaves, and the incision under the cutting shall be smooth. After cutting the cuttings from the mother, use clean wet cloth to keep wet, put them into 1000 times methyl thiophane to soak and disinfect for 5 minutes, take them out and dry them slightly, then dip them in 500ppm rooting agent solution for 5 seconds, cut them into 50-hole forest tray, insert one cuttings in each hole, spray water immediately after cutting is completed within 2 hours, and enter the maintenance stage.

6. Install plastic film arch shed on seedbed for heat preservation and moisture retention, requiring shading rate of 70-80%, air relative humidity of 80-90%, daytime temperature of 20-28 degrees, and night temperature of 15-23 degrees. Callus appeared at the base of cuttings of Pelargonium geraniferum L. on the 10th to 2nd day after cuttage, roots began to take root on the 15th to 18th day after cuttage, and seedlings were trained after the roots filled the holes on the 35th to 40th day after cuttage. When seedlings were trained, the environmental shading rate should be reduced by 50 - 60%, and the relative humidity of air should be 50 -60%. 1/3 of plastic film could be opened for ventilation and humidity reduction, and after 3 - 4 days, all plastic films should be opened, and seedlings could reach the emergence standard in 4 - 6 days.

What is geranium geranium culture

Beauty ladies like to use some relatively good perfume, at the same time in order to protect the skin, but also often use essential oil skin care products and so on, and in fact few people know that these daily use of perfume skin care products and geranium have a relatively close relationship. Geranium is a plant originally grown in South Africa and other places. Due to its special plant properties, geranium is widely used in perfume industry.

What is geranium:

Habits: like warm, not cold, winter minimum temperature should be maintained above 2℃. Avoid high temperature and heat in summer, and show semi-dormant state after summer. Sunlight is preferred, but semi-shade is preferred in summer. Avoid water wet, especially in summer should pay attention to water control, water when more easy to rot root death.

Origin: Southern Africa.

Characteristics: perennial herbs, plant height 60-70 cm, the whole plant are long fluff. Stems erect, old branches lignified. Leaves palmate deeply divided, lobes split into lobules, with shallow serrations, foliar wrinkled, fragrant. 3-4 Flowers in leaf axils on top of branches, umbels, 4-8 flowers, pink, small in shape.

Function: Fragrance has rose fragrance, which is a spice with high value and wide use. Dry leaves can be used in many aromatherapy.

Geranium culture:

1. Cutting

Geranium requirements fertile drainage good soil, potting soil available humus soil, chaff ash, garden soil each 1/3, and then add a small amount of calcium superphosphate mixed can be. 1-year-old branches with strong growth and short thick internodes were selected for cuttage planting. In April, May or September, October, cut thick branches with terminal buds, 5-8cm long, cut after the incision is dried, and retain 2-3 terminal buds. Shade, moisture, about 15-20 days can take root survival. When cultivating new varieties, artificial pollination is often used, seeds are collected and sown at that time, and germination occurs at a temperature of 20 DEG C after 7-10 days.

Cuttage seedlings grow new leaves can be on the pot, select neutral culture soil for pot soil, give sufficient light. Topdressing is applied every 10 days during the growth period. Master the principle of "no watering, no watering, no watering". 7-8 In the high temperature season, the leaves are yellow, indicating that the plant has entered a dormant state. At this time, it should be placed in a cool and ventilated place to prevent rain. The autumn climate turns cool and the plants recover their vitality and enter the growth and flowering period. At this time, the withered branches and leaves are cut off and normal water and fertilizer management is carried out. Low temperature greenhouse maintenance in late autumn, winter temperature above 5 degrees Celsius. Proper maintenance, flowering as usual, long sunshine conditions conducive to flower bud differentiation and flowering. Spring seedlings can bloom in autumn, autumn seedlings can bloom in early summer of the following year, and often change pots after autumn flowers wither.

2. Transplanting

1-year-old branches with strong growth and short thick internodes are selected for intensive seedling cultivation on seedling beds, and then transplanted to fields. This method is generally used in areas with heavy frost in winter, with a small arch shed or cover weeds to facilitate safe winter, after the next year's late frost, you can plant in the field.

Geranium cultivation techniques

1, soil

Pelargonium requirements fertile drainage good soil, potting soil available humus soil, chaff ash, garden soil each 1/3, and then add a small amount of calcium superphosphate mixed can be.

2. Watering

Pelargonium is drought tolerant and afraid of ponding. Therefore, during the growth process, water is properly controlled. Too much watering, pot soil moisture content is too large, will cause excessive growth or rotten roots. Spring and autumn growth and flowering exuberant, can be appropriate more watering, but also should keep the pot soil moist as appropriate. Winter temperature is low, plant growth is slow, should try to water less.

3. Fertilization

During cultivation, in addition to applying sufficient base fertilizer, in the growing season, especially in the flowering period, thin liquid fertilizer can be applied once every 7-10 days. It is better to dilute with decomposed livestock manure and water, or to irrigate with decomposed cake fertilizer water. 3-5 days before fertilization, less or no watering, watering when the pot soil is dry, it is more conducive to root absorption.

4. Light

Geranium is native to South Africa and likes sunny, warm and well-ventilated environmental conditions. In spring and early summer, when the light is not too strong, the flowerpot can be placed in a place with sufficient light to receive sufficient light, but in the hot season of early summer and autumn, it should be placed in a shaded place to avoid direct light, otherwise, the branches and leaves will be burned.

5, pruning

In order to make the plant shape beautiful and bloom more, if the plant grows too vigorously in spring, thinning and pruning can be carried out. After flowering, cut off residual flowers and over-dense branches in time. Dormancy period is also a pruning, cut off yellow old leaves, thinning over dense branches, too long branches for short, in preparation for dormancy period, new branches, continue to bud flowering. In addition, geranium itself has a special smell and rarely suffers from pests. No need for prevention.
