Winter coral planting, soil, water and fertilizer, light and other conditions are conducive to the normal growth and flowering results of the plant, so it can be flourishing and red fruit without careful management. Due to the limitation of the cultivation container and the climatic factors, the potted plants are likely to cause the roots of the plants to defoliate or fall off. The dried soil is easy to cause the roots of the plants to shrink, the plants are withered and fallen, and it is difficult to normal flowering results. Especially during the flowering period, if the potting soil is impermanent and the fertilizer concentration is out of control, it is easy to cause it to only bloom, not to bear fruit or light flowering, and less results.
Potted winter corals require the use of loose, fertile, well-drained, organic-rich sandy loam, plus 5% tart cake or chicken and duck manure. After the seedlings are transplanted into the basin, spraying a new high-fat film can effectively prevent the water from evaporating on the ground, the moisture of the seedlings is not transpiration, the pests and diseases are isolated, the seedling period is shortened, the new environment is quickly adapted, and the growth is healthy.
After the slow seedling period has survived, the normal water is used to maintain the soil moisture, and the soil is fertilized every half month. And give plenty of light, when the plant reaches about 10 cm high, start the topping and promote the sprout. Spraying Huahua No. 3 can transform plant vegetative growth into reproductive nutrition, inhibit the main shoots from becoming mad, and promote flower bud differentiation. When the plant enters the pregnancy bud period, the fertilization is suspended, and the watering is controlled at the same time. Try not to spray water, and avoid the pollen to pollen. Spraying strong fruit and refreshing fruit, increase nutrient delivery, prevent falling flowers and fruit drop. When the fruit grows to the size of mung bean, it can restore the water of the cake and increase the amount of watering, and at the same time give appropriate foliar spray. When the diameter of the fruit is as long as 0.5 cm to 0.6 cm, the excessively dense small fruit should be properly removed, and the fruit and fruit can be removed, so that the fruit on the potted plant can be evenly distributed and evenly sized, thereby improving the potted plants. Enjoy the value.
Potted winter corals are prone to anthracnose in high temperature in summer, mainly affecting leaves, but also can damage the stems. There are two kinds of symptoms: one is on the time slice, and the round spots on the leaves at the early stage of the disease are round reddish brown. Turned to grayish white, then turned dark brown and produced a black dot of the wheel arrangement, that is, the conidia disk of the pathogen, the disease occurs at the leaf edge and the tip of the leaf, and in severe cases, the leaves die black. The pathogen is a fungal disease, and the mycelium is overwintered in the parasitic residue or soil. The old leaves begin to develop from late April to early May, and the onset is faster in June-July, and the incidence in the rainy season is heavier. The new leaves are from August. Start the disease. The potted flowers are placed too densely, and the leaves cross each other to facilitate disease transmission, but the disease resistance between the varieties is different.
Control method:
1. Disease prevention and treatment:
1. Choose excellent varieties that are resistant to disease.
2, in the early stage of the disease, cut off the diseased leaves in time to prevent the spread of the bacteria, avoid placing too dense and pouring water, and often keep ventilation and light.
3. Spray 50% carbendazim WP 700-800 times or 75% chlorothalonil 500 times at the beginning of the disease.
2. Pest control:
Winter coral pests are mainly aphids, small in size, green or black, and often clustered on a variety of flowering branches and leaves to suck nutrients.
Control method: spray with 40% omethoate emulsion oil 2000 times solution or 50% dichlorvos EC 1500-2000 times solution.
