Cannon flower cultivation management:
The first point: the cultivation site should be selected in a sunny and ventilated place. The cannon flower is not strict with the soil, but it grows stronger in the fertile soil rich in organic matter, well-drained and deep in soil.
The second point: the acupoints should be dug up, and the base fertilizer should be applied. The base fertilizer should use the composted compost and add the appropriate amount of bean cake or bone powder.
The hole soil should be mixed evenly, and it needs to be poured once to allow the plant to be fermented for 1 to 2 months before it can be planted. The first watering after planting should be thorough and shaded. When the height of the seedlings is about 70 cm, a scaffolding should be set up, and the branches should be pulled onto the shelves, and the toppings should be carried out to promote the germination of the side branches to facilitate more flowering.
The third point: fertilizer, water should be appropriate.
The production of the cannon flower is fast, the flowering is long, and the flowering period is long, so the fertilizer and water are sufficient. A top dressing is required every month during the growing period. Topdressing should be done with decomposed thin bean cake water or compound fertilizer to promote its leafy and full bloom. To keep the soil moist, the number of watering should be determined according to the wet condition of the soil. In addition to watering in the hot summer, water is sprayed 2 to 3 times a day and the surrounding ground to sprinkle water to increase the air humidity.
In the autumn, when entering the flower bud differentiation stage, the watering should be reduced, and the fertilization should be based on phosphate fertilizer. In the growing season, a thin liquid fertilizer combined with nitrogen and phosphorus is applied for about 2 weeks. During the bud stage, a liquid fertilizer mainly based on nitrogen fertilizer is applied to facilitate flowering and plant growth. Watering should be seen dry and avoid water in the basin. In summer, the temperature is high, watering should be sufficient, and water should be sprinkled on the ground near the pot to increase the humidity of the air. In the autumn, it begins to enter the flower bud differentiation stage. At this time, watering should be appropriately reduced in order to control vegetative growth and promote flower bud differentiation.
The fourth point: potted cannon flowers, should use deep-tube pots, culture soil should use mainly humus soil, garden soil, mountain mud, etc., and apply appropriate amount of composted compost, bean cake, bone powder and other organic fertilizers as base fertilizer.
After planting, it is the same as the plant management. Planting grows better in the loose, fertile and well-drained slightly acidic soil; the south can be cultivated in the open field, the northern area needs potted plants, and the winter season enters the room for winter, the potted plants can be cultivated with humus soil, compost soil and sand soil, plus A small amount of cake fat is used as the base fertilizer.
Fifth point: adjust the shape of the plant.
The cannon flower is a perennial evergreen climbing vine with a tendril that can be climbed up with the help of other objects. When the family is training, in order to improve the ornamental effect, large and deep flower pots can be used for planting. When the seedlings grow to a certain height, a flower stand is placed in the pot, and the stems are tied to the flower stand, and the distribution is evenly distributed. Cultivate on a sunny balcony. It can also be planted in a large basin, with a flower stand on the balcony to allow it to climb upwards. When the branches grow to a certain height on the attached objects, they need to be topped to promote the sprouting of new branches for easy flowering. The branches that have been flowered are not blooming in the coming year, and the newly growing branches are pregnant, so some old branches and weak branches should be cut off in time to avoid the consumption of nutrients and affect the flowering in the second year.
The sixth point is that the flower is not cold-resistant, and it needs to be moved indoors to winter in the northern part of the country.
Place the indoor sunny area during the winter, and control the watering, stop the fertilization, and keep the room temperature above 10 °C. Generally, the room temperature should be gradually increased in the middle and late December, and at the same time, watering and fertilization should be carried out in an appropriate amount. The flowers can be bloomed from February to March. Breeding cannons can be used for cutting and pressing, but the rooting method is faster and the survival rate is higher. Generally, after the flower is selected, the strong branches of the year and above are selected, and some of the parts that are to be buried in the soil are inscribed, buried in about 10 cm of thick soil, and fixed with bamboo nails or the like, so as not to eject. Always keep the soil moist, usually in the autumn, you can cut off the mother and plant it separately.
The seventh point of pest control:
1. Disease: Common leaf spot and powdery mildew of cannon flower, sprayed with 5% solution of 50% carbendazim WP.
2, pests: cannons and insect pests have whitefly and scale insects, can be sprayed with 40% omethoate EC 1200 times liquid.
Eighth point
Garden application: Planted in courtyards, grids, flower gates and fences for vertical greening. Large plants can be used, placed in flower sheds, open-air restaurants, courtyard doors, etc., for top and surrounding greening, with good views; it is also suitable for planting flower walls, covering soil slopes, or balconies for high-rise buildings. It is a vertical or paved greenery, showing the grandeur and grandeur. It is an important climbing flower in southern China. Dwarf varieties can be curved into a pattern shape for potted flower cultivation.
