Cactus plant rot
Cactus flowers have strong adaptability and are easy to cultivate and manage. However, when planted, it is most vulnerable to rot disease. Seeded seedlings are perishable, grafted and perishable, cuttings inactive, perishable, and forming plants sometimes rot. The causes of rot disease can be summed up in two main categories: one is pathological; the other is physiological. Pathological rot is caused by infection with pathogenic bacteria. The soil and surrounding environment, water and fertilizers, as well as the tools used for reproduction, have pathogenic bacteria and fungi. If you do not pay attention to disinfection and sterilization, bacteria can easily be found in soil and environment. It reproduces in large numbers and starts harming human-made wounds. These wounds are usually the "channels" for invading bacteria. When the environmental conditions are conducive to the proliferation of bacteria, the plants, especially the seedlings, often die rapidly in large numbers in batches. The physiological causes of rot disease of cactus flowers are as follows: First, the basin soil is too wet. Cactus plants like good drainage, strong permeability, sandy loam with lime. If the basin soil is drained, the air is poor, and the soil is too moist, it can easily lead to rot and necrosis of the root tissue. If not handled in time, the whole plant will die. If it continues to be excessively humid, cactus flowers will be infected with pathogenic bacteria, which is also an important reason for cactus flowers to produce bad stems. The second is excessive fertilization. Application of excessive nitrogen fertilizer or application of unfermented fertilizers and fertilization at high temperatures and winter dormancy, are prone to rot. The third is excessive shading. Plants do not receive sufficient light, resulting in poor plant growth, debilitating growth, and vulnerability to pests and diseases. If the ventilation is poor, the potted earth will be overly humid for a long time and cause rot. Prevention of rot disease. The first is to improve the environmental conditions at the cultivation site. Cactus flowers like sunshine, but not exposure, summer should be appropriate shading at noon, but in the winter should be placed on the place to see light, must not be placed in a dark corner. The best growing environment is clean, well ventilated, well lit, and moderate in temperature, so that the occurrence and spread of pathogens can be greatly reduced. The second is to strengthen the cultivation and management. The first is a reasonable watering. Into the growth phase should be timely watering, so do not do not poured, pouring is drenched. For pteridophytes, do not pour water into the recesses of the plants. It is best to water in the evening and avoid watering at noon or in the hot sun. Followed by timely and appropriate fertilization, the growth period is generally about half a month fertilization, fertilization should be controlled after the fall, dormancy in winter and summer hot season to stop fertilization, fertilization concentration should not be too large, so thin and hard ground facilities. Organic manure must be used after it has been decomposed and diluted. Thirdly, if a yellow-brown soft spot is found on the plant caused by a localized disease, it should be immediately extirpated and a part of the adjacent healthy tissue should be dug out, then coated with charcoal powder or sulfur powder to dry the wound and isolate it. Cultivation for some time. When the part of the local rot is large, it is possible to cut out some of the healthy part, cut it, or graft it. Since the plants around the susceptible plants may be re-infected, carbendazim and thiophanate-methyl should be sprayed immediately, and environmental ventilation should be strengthened. Fourth, some large plants have grown well and their plant tissues are tight. After being damaged by pests or other causes of root damage, they sometimes do not show changes in appearance, but they gradually weaken over time and eventually decay. Therefore, in the cultivation should pay attention to observation and found that more pests in the basin or potting after watering is not dry, it should be suspected of plant root system problems. At this time, there is the possibility of recovery from the tapping inspection. Frequent spraying of fungicides on the plants or in the surrounding environment has a certain effect on the occurrence of pre-preserved rot. The commonly used bactericides are from 0.15% to 0.35% concentration of dexamethasone, or 0.1% concentration of carbendazim, thiophanate, etc. .
