Cultivation and maintenance methods of Phyllostachys pubescens

1. Cultivation of pointed leaf carnation

Dianthus oxyphylla has many advantages such as drought resistance, water saving, alkali resistance, barren resistance, cold resistance, long green period, etc. The following problems should be paid attention to when planting:

1. The soil of the selected planting site is preferably sandy or semi-sandy soil. In case of clay soil, sand can be mixed to improve it, which is conducive to drainage and root growth.

2. Soil preparation generally requires only ploughing 15 to 20 cm deep soil layer, picking up stones and rubble, without sifting the soil, leveling the plot and planting. If there is a low-lying area, drainage facilities should be made to ensure the normal growth of plants. Whether the plot is flat or not is the key to whether it can be flat after forming the flat.

3. planting method

(1) Divide the whole pier into small piers about 5 to 6 cm in diameter. Dig a hole about 10 to 12 cm deep in the planting ground, bury the small pier seedlings in the hole, and bury the branches and leaves three or four cm above the ground. Compacting the soil and seedlings after backfilling ensures that there are no gaps around the plants. Plant division can greatly reduce planting costs.

(2) The whole pier planting method digs out a hole with the same depth as the root system of Dianthus oxyphylla, vertically puts the root of the seedling into the hole (to make the root system stretch), and compacts the surrounding soil and seedlings after backfilling. The whole pier planting can achieve the effect of forming a lawn at that time.

(3) Nutrition pot planting method Nutrition pot planting method is relatively simple, the seedlings planted in the nutrition pot are transplanted to the ground, and after planting, they can be watered once, and there is no need to slow the seedlings.

4. planting precautions

(1) When planting, it is necessary to keep the spacing of each plant evenly, so that it is horizontal and vertical, which is conducive to balanced growth and beauty of seedlings. Planting spacing is the key to the length of time to form a lawn. For example, it takes 3 months to achieve the effect of forming a lawn, and about 25 plants can be planted per square meter.

(2) After planting for two weeks, observe whether the seedlings survive in time. If the seedlings are not found to be yellow and the roots grow new green buds, it means that the seedlings have survived. If it is found that the seedlings gradually wither and the roots do not sprout, it indicates that the seedlings have not survived. At this time, it is necessary to supplement the seedlings in time to facilitate the overall formation of the lawn.

5. Water and fertilizer management After planting, water and fertilizer management is the key to seedling survival.

(1) Watering in a relatively flat area, watering thoroughly at one time, and then watering again after observing the growth of seedlings for a few days. Do not water after survival, do not water other plants together when watering.

(2) Planting in mounds or areas where water is not suitable, watering frequently before the sharp leaf carnation survives, keeping the soil with sufficient moisture, and stopping watering after survival. Summer season due to higher temperatures, water evaporation during the day fast, morning watering best.

(3) If the soil is poor or the user wants to form a lawn faster, organic fertilizer or chemical fertilizer can be applied.

II. Daily maintenance management

1. Water Dianthus oxyphylla is a drought-tolerant plant. It can only be watered once in the beginning of spring and before freezing in winter. Natural rainfall can meet the needs. If you want to make a lawn as soon as possible, you can increase the amount of watering appropriately according to the degree of drought.

2. Pruned pointy carnations grow low, 8 to 10 cm tall, and generally do not need pruning. If you want to mow, the same method as lawn mowing, but the height control is about 8 cm.

3. Pest control has not yet found that there are pests in Dianthus oxyphylla, but it is easy to appear blight in summer mildew season (yellow at the top of Dianthus oxyphylla center and spread to the periphery). Agricultural streptomycin can be applied, effective after a week.

4. If individual dead seedlings are found during daily maintenance, they can be replanted nearby.

III. Mistakes in planting and conservation

1. Planting is not done according to the required plant spacing, spacing is too large or too small. Normal planting spacing should be about 20 cm, but some have reached 40 to 50 cm. This results in small spacing has grown closed, and large spacing is still not completely flat, the surface bare.

2. Pointed leaf carnation after survival, regardless of any wild weeds appear withered also do not apply medicine or even die do not make up seedlings.

3. Some people think that pointed leaf pink drought and cold resistance, do not irrigate frozen water, green water, also do not fertilize its natural growth.

The above problems are the main reasons for poor growth and slow turf formation after planting, and attention should be paid to them.
