Ground cover chrysanthemum planting strategy

  0010010 nbsp; 0010010 nbsp; How much do you know about the cultivation of ground chrysanthemum? let's figure it out together!

  1, breeding methods

Its reproduction includes sexual reproduction and asexual reproduction. Sexual reproduction is sowing and breeding. This method has low cost and large reproducibility. It can obtain a large number of varieties, but the characteristics of the offspring are different. Asexual reproduction includes branching, cutting and grafting. In order to maintain the excellent traits of ground cover chrysanthemum, asexual reproduction is generally used, and two methods of branching and cutting are commonly used. The ramets reproduction generally takes place in the cloudy days from the end of 4 month to the beginning of 5 month, and in the afternoon on consecutive sunny days. Cutting propagation is generally carried out on cutting beds or nursery trays from April to 5 months. Most cuttings take root two weeks later, and are generally planted 2 5-30 days after cuttings.

  2, colonization and management

It should be planted in sandy soil with good ventilation and drainage. Chrysanthemum should be applied to the ground layer, and plantar fertilizer should be applied before planting. The row spacing of the plant is 30 cm × 40 cm. In that year, the plants can be planted properly and cover the ground as soon as possible. Sowing in the next year. When planting, the root system should be expanded, and the planting depth should be 1-2 leaf nodes of the root buried in the soil. The roots should be tamped with soil, the seedlings should be planted, and then watered. In the early stages of growth, weeding and weeding should be repeated several times to increase the permeability of the soil. In order to reduce the accumulation of water in the rainy season, when the plant grows to 20 cm-30 cm high, it can be combined with fertilization to cultivate the soil. After the ground-covered chrysanthemums make the seedlings grow slowly, the heart should be removed in time, leaving only four leaves to facilitate more branches. After survival, watering and fertilization are generally no longer required. In the year of planting, there is usually no need to remove the heart. The next year, due to vigorous growth, the relative density of plant spacing is large, which can easily lead to overgrowth and basal leaf shedding. Therefore, measures such as water control, sparse seedlings and sparse branches should be taken from the following year. Generally, the ear drop in the later period should not be later than the 7 month 20 day, otherwise the flowering period will be delayed or even affected. In the growing period, it is necessary to clean up the residual flowers in time, pruning the oversized branches and diseased branches, to achieve the nutritional supply of strong branches, and to maintain an excellent plant type.

  3 , disease prevention

During the entire growth process of ground chrysanthemum, attention should be paid to the prevention and control of diseases and insect pests. It is necessary to pay attention to leaf spot disease, virus disease, aphid disease, grub disease, etc., and to carry out appropriate drug control in combination with the disease.
