Planting methods of Phyllostachys pubescens seeds

Phyllostachys pubescens is usually sown in spring, first arrange the seedbed, trench according to the row spacing 30cm and depth 10cm, spread the seeds evenly, cover with a layer of plant ash and fine soil, and then compaction and watering. Every year, we should regularly plough and weed, apply thin farm manure, get out of the nursery for about three years, and then plant it.

I. growth habits

1. Environment: Phyllostachys pubescens is cool and cold-resistant, suitable for growing in a warm and humid environment, and easy to maintain.

2. Soil: Phyllostachys pubescens is resistant to drought and moisture, so it is suitable to be planted in well-drained and fertile sandy soil.

3. Fertilization: Phyllostachys pubescens prefers fertilizer, and liquid fertilizer, such as phosphate fertilizer and potash fertilizer, can be applied once a month in the process of growth.

4. Pruning: after growing for several years, the branches and leaves of Phyllostachys pubescens are gradually aging and falling off, which can be pruned properly, and the 15cm of the main stem can be retained. Generally, pruning is carried out in April, and the crown can be expanded in autumn.

5. Flowering: Phyllostachys pubescens usually grows in woods or bushes and usually blossoms from May to July.

II. Methods of reproduction

The propagation methods of Phyllostachys pubescens are as follows: sowing propagation, split propagation and cutting propagation.

1. Sowing and reproduction

(1) generally sowing in spring, the seedbed is first arranged, then ditched according to the row spacing 30cm or so, the ditch depth is about 10cm, and the seeds are evenly sown. After sowing, the seeds are covered with a layer of plant ash and fine soil, and finally compacted and watered.

(2) the growth of seedlings is relatively slow in the second year, so weeding and loosening the soil can be carried out regularly, and then some thin farm manure is applied. After that, regular weeding and fertilization are needed every year, and it can be out of the nursery and planted in about three years.

2. Ramet propagation

Generally, split propagation is carried out before sprouting in spring or autumn, first dig out the plant, shake off the persistent soil above, cut it in the position of weak combination of roots, leave 2-3 stems per clump, and leave some roots at the same time. Finally, cut off some larger pinnately compound leaves and put them on the pot, which will blossom and bear fruit in about 1-2 years.

3. Cuttage propagation

Generally, cuttings are stopped before new buds sprout or in summer. Indoor maintenance needs to strengthen ventilation and light transmission to prevent diseases and insect pests.

Third, timely watering

1. Phyllostachys pubescens can be watered according to the principle of dry and wet, and the amount of water should be increased appropriately in the dry season to keep the soil moist. In summer, the soil should be watered once in the morning and once in the evening. In order to prevent the leaf tip from scorching at high temperature and affecting its appearance, foliar spray is needed about 2-3 times a day to keep the leaf surface moist.

2. When Phyllostachys pubescens blossoms, the pot soil should not be dry. In order to improve the air humidity, water can be sprayed around the plant and on the ground. In winter, Phyllostachys pubescens enters a semi-dormant period, the pot soil should not be too wet, and a small amount of water can be watered at noon.

IV. Rational fertilization

The main results are as follows: 1. During the growth of Phyllostachys pubescens, thin fertilizer should be applied to fine seedlings every 15 days or so, and dry fertilizer should be applied to adult plants in May, August and October every year, and a small amount of fertilizer should be applied for the first and second time, and the amount of fertilizer can be increased appropriately for the third time. mainly cake fertilizer and sesame residue.
