Cultivation techniques of Phyllostachys pubescens

Phyllostachys pubescens is also known as bamboo. Phyllostachys pubescens grows fast, matures early, has high yield and has a wide range of uses. After five to ten years of afforestation, it can be cut down and used year after year. Do you know all the cultivation techniques of Phyllostachys pubescens?

I. cultivation techniques of Phyllostachys pubescens

1. Seed collection

The bamboo forest with more than 10 years old, good site conditions and normal flowering and fruiting bamboo forest should be selected for seed collection. The seeds of Phyllostachys pubescens are harvested from September to October, and the seeds are often mixed with insecticidal powder to prevent insects from eating.

2. Nursery site selection

Nursery land can choose to raise seedlings on the slopes of soil ridges or hilly lands, with raw wasteland, loose land and fertile sandy soil as the best.

3. Make a bed by preparing the ground.

Nursery land to intensive cultivation, after picking clean grass root stones, you can get up the border, border width of 1 meter, height of 15-20 cm, length can be determined according to the actual topography. Apply 100 kg compound fertilizer per mu as base fertilizer.

4. Sowing season

Autumn sowing is best, but also spring sowing, spring sowing time should be completed before the end of March.

5. Sprouting

Before sowing, rinse with clean water to mix the seed powder, mix the seeds with wet fine sand for budding treatment, and sprinkle water once a day. When the seeds begin to show white, sift out the sand and sow.

6. Sowing seeds

The sowing method should be on demand, the row spacing is generally 25cmX25cm, and 8-10 seeds in each hole are evenly covered with fine soil.

7. Nursery site management

For the purpose of cultivating 2-3-year-old bamboo seedlings, the ground laying management was carried out.

Cover a layer of thin thatch and water once, and pay attention to prevent rodent damage. After bamboo seedlings are unearthed, the cover should be removed in time and weeding can be started. Water should be drenched during drought. Sparse human feces should be used for fertilization. Fertilize once or twice a month. In order to distribute bamboo seedlings evenly and increase the yield of bamboo seedlings, the overdense bamboo seedlings can be transplanted into the ground holes lacking seedlings in overcast and rainy weather, with 1-2 plants (clusters) in each hole. Bamboo seedlings begin to tiller 50 days after they become a scholar, and usually form small bamboo clumps with a height of 30ml / 40cm after June to July.

One-year-old bamboo seedlings are divided into individual plants, and then transplanted to the nursery, according to the row spacing 25cmX25cm, after a year of cultivation, fertilization, growth and tillering into clumps, which is about the same as the above-mentioned on-demand seeds grow into annual seedlings, and can be divided into a long-term nursery after once a year.
