How much does a high-quality, high-yield Phyllostachys praecox usually cost per plant? How many plants are usually in a clump? What is the planting density? What are the cultivation techniques?

Phyllostachys praecox, also known as sand bamboo, Gui bamboo, early bamboo, Lei bamboo, and Yan bamboo, is a high-quality, high-yield bamboo species grown for shoots. It also has low costs and good benefits. So how much does Phyllostachys praecox usually cost per plant? How many plants are usually in a clump? What is the planting density? What are the cultivation techniques? According to the Jiangsu landscaping base, Phyllostachys praecox with a diameter of 2CM at breast height and a height of 350CM costs about 2 yuan per plant.

How many plants are usually in a clump of Phyllostachys praecox?

Phyllostachys praecox is a running bamboo, so there is no concept of a clump. If there is, it only means several culms dug up together as one root ball with several culms. Only clumping bamboos have the concept of a clump, but even for clumping bamboos, the number of culms per clump varies. For example, with hedge bamboo, it is possible to have from a few culms to several hundred culms.

What is the planting density of Phyllostachys praecox?

The planting density of Phyllostachys praecox is generally 2.5m×3m or 3m×3m, with 70-90 plants per mu.

What are the cultivation techniques for Phyllostachys praecox?

1. Site selection: The soil should be loose, well aerated, and fertile, with deep, well-aerated, and water-retentive dark sandy soil or sandy loam being best. Ordinary red soil and yellow soil are also suitable for cultivation. Saline-alkali soil and calcareous soil are not suitable for cultivation. The soil depth should be more than 50cm, and the PH value should be about 4.5-7.0, with slightly acidic or neutral being preferable. The groundwater level should preferably be more than 1m. A slope of less than 20° and an altitude below 250m are best. Phyllostachys praecox likes moisture and fears waterlogging, likes light and fears wind, so it should be planted on southeast slopes and south slopes that face away from the wind and have sufficient sunlight.

2. Mother bamboo selection: It is best to choose 1-2 year old mother bamboo, because the rhizomes of this kind of mother bamboo are strong rhizomes with strong vitality, plump lateral buds, and well-developed root systems, and are easy to grow rhizomes and roots after planting. Also pay attention to selecting mother bamboo that grows vigorously, has evenly spaced internodes, lower branching, no pests or diseases, and no flowering branches. The mother bamboo should not be too thick or too thin; generally, a diameter at breast height of about 8cm is suitable, with 1 plant per clump and a few with 2 plants, carrying 8-10 kg of native soil. When digging, be careful to keep the rhizomes well, with 10cm of the incoming rhizome and 15cm of the outgoing rhizome. Keep 5-7 nodes of branches, and cut off excess branch tips to reduce water evaporation.

2. Phyllostachys praecox afforestation can be carried out except during the hottest days of summer, freezing days, and the bamboo shoot growing period, but the plum rain season from late May to June and the osmanthus season in September are best. The planting density is generally 2.5m×3m or 3m×3m, with 70-90 plants per mu. On sloped afforestation land, plant along contour lines or build terraces, dig 80cm×50cm×40cm planting holes, keep the bottom of the hole level, place topsoil to one side, first put about 10 kg of rotted barnyard manure or about 1 kg of rapeseed cake into the hole, cover the fertilizer with 10 cm of fine soil, and then plant the bamboo seedlings, first backfilling with topsoil, then with subsoil; alternatively, do not apply base fertilizer for the time being, plant the bamboo first, and apply fertilizer after the mother bamboo survives the following year. Absolutely avoid applying large amounts of urea, compound fertilizer, or concentrated livestock manure in the hole, otherwise it will cause fertilizer damage to the mother bamboo and affect the afforestation survival rate. Planting bamboo should be shallow rather than deep, and can be slightly deeper than before; generally, the rhizome should be 20-24cm in the soil. After planting the mother bamboo, if there is insufficient rainfall, water appropriately, and try not to let the bamboo leaves lose water.

Disease and pest control

1. Aphids

Commonly known as greasy insects or oil insects, with damage being more serious in spring and summer. 1. Maintain a reasonable bamboo forest density and enhance ventilation and light transmission in the forest. 2. In early spring, spray for control with 40% omethoate 1000-1500 times dilution or 80% dichlorvos 800-1000 times dilution. 3. Pay attention to protecting natural enemy insects such as ladybugs and lacewings.

2. Bamboo leaf roller

Commonly known as leaf-rolling worm, it generally causes damage from May to July, with mid-June being the peak damage period. 1. From May to July, use black light traps to kill adults (moths). 2. In June, spray for control with 20% fenpropathrin 1000 times dilution or 80% dichlorvos emulsifiable concentrate 1000 times dilution. 3. In autumn and winter (October to December), carry out forest land reclamation and kill larvae or soil cocoons.

3. Bamboo small wasp

Commonly known as firecracker insect, the internodes of damaged small branches become swollen, and the damage period is from May to September. 1. Strengthen tending management and loosen soil and apply fertilizer in time. 2. In early to mid-May, spray for control of adults with 80% dichlorvos 1000-1500 times dilution or 50% fenitrothion 1000 times dilution. 3. In the early larval stage (mid-May to June), inject 40% omethoate diluted 10 times with water into the bamboo cavity, about 2 milliliters per plant.

4. Wireworm

Commonly known as iron wire worm, it is the main underground pest damaging Phyllostachys praecox shoots. When the soil temperature reaches about 15°C, the pest becomes active and causes damage, with March to April being the peak damage period. 1. When manually digging out degraded shoots, kill the pests directly. 2. In bamboo forests with severe damage, after the shoot period (late April), spray or drench with 90% trichlorfon 400-500 times dilution, or evenly work 5% phoxim granules into the soil at 2-2.5 kg per mu to a depth of about 15 centimeters.

5. Bamboo witches' broom disease

Commonly known as bamboo broom disease or bird's nest disease, the affected branches continuously grow side branches shaped like a broom or bird's nest. 1. Strengthen tending management, loosen soil and apply fertilizer in time, and improve disease resistance. 2. Clean up the forest land and cut down heavily diseased bamboo. 3. Before April, prune all witches' brooms in the forest and burn them.

6. Bamboo culm rust disease

It mostly occurs on the middle-lower part or base of bamboo culms. In summer and winter, the diseased parts produce yellow fungal spores. 1. Strengthen tending management and maintain a reasonable standing bamboo density. 2. In winter, remove heavily diseased bamboo from the forest. 3. Before the end of March, manually scrape off the yellow fungal spores and part of the surrounding bamboo surface, taking care not to skip cuts or leave any behind.
