Planting methods and matters needing attention of potted Buckeye

If you have seen the appearance of Doucai, I believe it will be attracted by its unique beauty. Rabdosia angustifolia occupies a high position in medicine in China, and its ornamental value is not inferior to that of other flowers and plants. The flowering potted cabbage is very beautiful and unique, so it is suitable for viewing, so it is a good choice for family potted plants.

How to raise Chinese cabbage

1. Upper basin

After 5 to 6 weeks of germination, 3-4 cm diameter hole plates can be used for transplantation. after 5 to 6 weeks, blue flowers can be transplanted into pots with 10-15 cm flowerpots, fan-shaped ones can be transplanted into pots with 7-11 cm flowerpots, and hybrids can be transplanted into pots with 11-16 cm flowerpots. Twice transplanting is beneficial to the quality of the plant.

2. Media

The soil content in the substrate is about 15%. About 15% organic matter (such as wood fiber and bark) can be added, and 1 to 1.5kg of fully balanced fertilizer and 1 to 2kg of slow-release fertilizer, iron chelate and micronutrient elements should be added to each cubic meter of substrate. The pH value should be between 5.5 and 6.2.

3. Lighting

A medium-and long-sunshine plant of the genus Euphorbia. Maintain the highlight level. Potted varieties need to replenish light in winter and spring, which is helpful to improve the quality of plants. In the middle of January, it needs to grow under long sunshine (16 hours) and continuous supplementary light (30000 to 40000 lux), and the temperature is kept at 12 ℃.

4. Temperature

The suitable temperature for growth and development is from 14 ℃ to 16 ℃. After root formation, the temperature decreased to 8 ℃ to 10 ℃. The change of temperature can improve the quality of plants. In spring, seedlings begin to grow at a temperature of 15 ℃ to 18 ℃ for 6 to 7 weeks. The temperature of 10 ℃ to 12 ℃ will prolong the cultivation time. Avoid high temperature and weak light conditions.

5. Fertilization

The amount of fertilizer needed is moderate, and the balanced fertilizer of nitrogen and potassium with the concentration of 130ppm to 150ppm can be sprayed once a week. Avoid high ammonium and nitrogen levels. No fertilizer can be applied after mid-September.

Planting methods and points for attention of potted Rabdosia angustifolia

1. Planting method of potted Rabdosia angustifolia

1. Selection of basin soil

For potted plants, you need to choose a slightly larger flowerpot and put the soil in the flowerpot, which can be sandy soil with good drainage or humus-rich saprophytic soil, and a little base fertilizer should be added to the soil.

2. Light and temperature

Douzi likes a cool climate, avoid high temperature but can be cold-resistant, and need to keep enough light. It is necessary to maintain the growth temperature between 15 ℃ and 35 ℃, with moderate light to avoid high temperature and sun exposure in summer, when shading is needed, or the potted plants should be kept in a semi-shaded place.

3. Watering and fertilizing

Euphorbia angustifolia needs to strengthen the management of reasonable watering and fertilization. In the peak period of growth, we need to give sufficient water, according to the degree of dryness and wetness of the basin soil to determine the amount and times of watering, but avoid stagnant water. Dry weather needs timely drainage, and after rain, it needs timely drainage, pay attention to maintain a certain amount of air humidity. Fertilization requires medium fertility. Fertilizer can be applied once a week, but the concentration should not be too high. Pay attention to stop fertilizing after autumn, in addition, you need to apply some phosphate and potash fertilizer before flowering to make the flowering more gorgeous.

2. Matters needing attention in the culture of Rabdosia angustifolia

1. Methods of reproduction

Basically, it is propagated by ramet or sowing, which can be sowed in spring or autumn, and ramet reproduction is mainly in autumn.

2. Pick the heart

During the growth period, it is necessary to pick the heart in time to control the height of the plant. After blooming, the remnant flowers can be cut off, so that it can be preserved as a foliage plant.

3. Diseases and insect pests

The main pests are aphids, which can cause mosaic disease and powdery mildew, which need timely and reasonable treatment.

How to reproduce Ipomoea oleifera

1. Sowing: sowing is better than pot sowing immediately after the seeds are ripe. In order to adjust the dormancy period, the seeds are sown immediately after harvest. Apply sufficient base fertilizer, rake fine and flat, make the seedbed, pour enough bottom water, sow the seeds evenly on the seedbed, cover with concrete soil to see the seeds. Keep the border moist, excessive humidity will cause rotten seeds, and seedlings will emerge in 140 days.

2. Ramet: the ramet is carried out from August to September, first cut off the upper branches and leaves of the plant, retain the lower sprouts of the growing point, then dig up the plant, shake off the soil, and plant it separately according to the main root. If the main root is senescent, it should be removed to make sure that there is a part of the root neck at the base of the bud, then cut it on the sand bed and plant it separately after taking root, so that the cuttings can blossom in the second year.

What to do with cauliflower mosaic disease

1. Symptoms

The disease occurred in the whole plant, with foliar shrinkage and deformity. The pathogen is caused by cucumber mosaic virus. The virus is spherical in diameter, 35 nm in diameter, the detoxification temperature is 60-70 ℃, and the in vitro preservation period is 3-5 days. There is a wide range of hosts. The route of transmission may be transmitted by friction between aphids and juices, causing disease-free and healthy plants to occur.

2. Prevention and control methods

Scientific and effective fertilization, more use of compound fertilizer, organic fertilizer, avoid partial application of nitrogen fertilizer, plus phosphorus and potassium fertilizer, so as to improve the nutritional conditions, improve the anti-virus ability of the plant, and timely loosen the soil and promote the root development of the plant. Get rid of weeds in time. Early prevention and control of aphids and elimination of virus vectors.

The maintenance method of Douzi is not very difficult, daily care with a little patience can make it grow very well, in the maintenance process not only need to prevent its diseases and insect pests, in the growth period of timely heart picking this step can not be less.
