Podocarpus The mode of reproduction

Podocarpus Sow

 Podocarpus Podocarpus
Seed : Podocarpus seed in acquisition down, try to be placed in a dry and ventilated place, seed storage conditions is best not to have too strong light, too hot too humid environment will also affect the preservation of Podocarpus seed, temperature difference is too general to make Romeos Hansong advance germination of seeds, the best storage Podocarpus seed the method is sealed into the refrigerator, keep the seed germination is not in advance will not let the seed moisture loss.
Soaking seeds before: Podocarpus seeds soaked for 4 days, let it fully absorb water, can use warm cold boiled water immersion, the seed germination rate higher. The time of sowing by row spacing sowing, each row spacing of 20 cm, 10 cm intervals per plant, seed sowing time of buried depth in buried seeds, then use grass cover to seed moisture. Seed to seed water every time, 8-9 days after sowing seeds after removal of grass cover, the sun shade, not the sun.
Sow : Podocarpaceae around 40 days after sowing seed will sprout and seedling to note is the interval between the too dense place will be small seedlings with soil transplanted into the vacant place, be careful not to let the new seedlings with water to ensure the survival rate of seedlings. When the plants to 6 leaves around the appropriate leaching of some methane diluted with water, it is best not to use fertilizer recommendations. Because the seedlings grow slowly, 1 years after transplantation, the spacing of 20x20 cm, 15 cm or into nutrition bags, each bag of 1 strains. One year after transplantation for 1 times, the spacing of 1x1 meters, after 3 years of breeding seedlings, seedling height up to 1-1.3 meters, width up to 1 square meters, the crown into the tower can be used as a garden or continue breeding seedlings.

Podocarpus Cuttage

softwood cutting
Cuttage refers to the seedlings in the growing season, with one year old half mature branches as cuttings cutting method, the specific methods of operation are: cuttage vigorous growth season in seedlings, their semi lignified branches, 2 according to the 4 section (or a piece of a leaf as a festival for a period) the length of each segment, about 10 centimeters above retain 1 to 2 leaves, 2 leaves 1 to remove the lower part. The cutting depth is about 5 cm. After cutting with water, dry cutting foliar water immediately after spraying once again in the seedbed of pesticide sterilization insecticidal, and then plug the bamboo bow, covered with plastic film, and then inserted some bamboo bow, the bamboo bow covered with black shading. Film, shade nets are fixed. Support the bamboo shade net arch up to 15 cm to 20 cm than supported thin bamboo bow, to prevent the shade net heat to the film inside, burn seedlings. So far, the cutting work is completed.
Softwood cuttings, the first half of the general in the mid to late 5 to early July, in the second half of 8 to 9 months in late mid late. The first half of the year should pay attention to prevent the occurrence of plug seedling diseases and high temperature burn. The second half of the seedlings in the late plug should pay attention to heat insulation, exposing the shade net time is late November in dry year off shade net time until late December.
hardwood cutting
Hardwood cutting refers to the dormancy period from 2 to March the sap has not flow in early spring, the thick branches completely lignified cuttings clipping a year ago. Need to pay attention to hardwood cuttings in early spring is to improve the soil temperature, the temperature control of greenhouse. In short, whether or softwood cuttings of hardwood cuttings, to do a good job of disinfection work of cuttings and soil, but also control the bed temperature, humidity, illumination. In addition, in order to improve the survival rate of seedling, but also appropriate to take some measures to promote rooting.

Podocarpus cultivation techniques

Podocarpus transplant

In the spring 3-4 month best transplant seedlings, seedlings to soil, soil ball, can be potted. After planting should be irrigated. Keep the soil moist growth period. Midsummer High temperature season should put half shade maintenance. Every February fertilizer 1 times. Pay attention to cold winter pot pot, can be buried in the soil, and reduced watering.

Podocarpus Material

To be surrounded by trees bloom is stretching disc, stem from base to top thickness, curved uniform change and graceful, branching is reasonable, the first pull point in 1/3 or 2/3 at the trunk, with the golden ratio, good ornamental effect on tree structure: select blank integer can play a multiplier effect, so the selection should be careful.

Podocarpus integer

Podocarpus is whorled branches, according to the trunk has been set Jing potential. Cut off branches, keep 2-3 branches at the appropriate site, with wire tied to the main branch, slightly drooping hair, technical force is not strong. Every June, July each pruning time, usually by pinching mainly (generally should be branchlets lignified after topping).

Podocarpus watering

Pot noodle shop 0.5 cm thick half decay with pine needles, water retention, fertilizer, mulch, prevent soil compaction effect. Boil dry and wet, not according to the "dry wet Bai" type of maintenance of podocarpus. Podocarpus kisui, usually should keep the soil wetness in summer every evening or early morning pouring a. And in the afternoon with a jet of leaf water; spring and autumn temperatures below 25 degrees, generally 2-3 days pouring a. In order to reduce the trouble maintenance in winter. The basin buried underground and process as the base, flexible permeable, wet and dry conditions in the basin according to the appropriate replenishment.

Podocarpus Apply fertilizer

The main concept of Podocarpus leaves, fertilizer should be mainly nitrogen, phosphorus and potassium as collector to. Spring with Huanpen, shizujifei, Ji Jieshi some thin and often trivial 01% alum fertilizer, urea and 3% leftover beer, the thick and green leaves.

Podocarpus Leaf picking

In order to improve the forming of Luo Hansong value, March Luo Hansong to remove the old leaves, "strip l.sprengeri:" call handle reserved for abstract, stimulating new tender and green bud growth.

Podocarpus Carved.

Decoration should be carried out in the dormant period. To cultivate the sincere and honest tree Cang fang.

Podocarpus Pest control

Podocarpus Pest

There is less damage but Podocarpus pests, hot summer dry season should pay attention to prevention of red spider. The red spider mite, with nymphs and larval mites cluster in the vicinity of Podocarpus leaf veins and leaf margin, shoots suck sap, the victim face of blade After showing a lot of powder green, gray white spots, lost natural luster, severe leaf gray white.
Control method: The red spider period (5-9 months) spray treatment Red spider The insecticides such as pyridaben, hexythiazox, neophyltin, spray 1 times every 10 days, using concentration reference manual.

Podocarpus disease

Main diseases Leaf spot and Anthracnose Harm。
Control method: 50% Methylthiophanate WP 500 times liquid spray. A pest Scale , Red spider and Cryptothelea formosicola Harm, available 40% Omethoate EC 1500 times pensha.
