How to control rotten roots in orchid cultivation? Please introduce the causes and methods of orchid rot: first, improper watering, too much Rain Water, or unreasonable structure of basin soil, poor drainage, sometimes the invasion of germs will lead to rotting roots. Rotten roots caused the orchid leaves to yellowing, atrophy, shedding, sometimes even the head of the Reed rotted, and even the whole plant died. The prevention and control methods of rotten roots of orchids can refer to the following methods: first, change the pot as soon as possible: if you find rotten roots of orchids, you should re-change the soil and plant materials on the pot. plant materials should pay attention to quality and water absorption performance, and it is better to burn soil or dry soil, charcoal and other plant materials. it can also be properly mixed with some coarse sand in the root Reed, and the effect is better. Second, control sunshine: after changing the basin for a period of time, can not be exposed to the hot sun, should be placed in a place of sun cover and ventilation, but should pay attention to the wind should not be too strong so as not to be affected. Third, pay attention to the planting method of changing the basin: in addition to ensuring that the soil in the basin is well watered, the plant material from the lower part of the Reed head to close to the root should be dense, and the Reed head should be planted deeper appropriately, which not only plays a protective role, but also prevents the Reed head from shaking or floating off the soil surface. Rotten roots and atrophied and yellowed leaves should be cut off to reduce nutrient loss, so that the nutrition of Reed head can be stored to maintain root development. Fourth, rational watering: in cultivation and management, the use of water should be strictly regulated, and the basin soil should be semi-wet and dry, neither white and dry nor obviously too wet. In case of rainy days, you should move to the place where the rain is sheltered, and try to control the humidity of the basin soil to ensure that it takes root normally. Appropriate fertilization: do not apply fertilizer after changing pots, wait until sprouting, apply a small amount of compound fertilizer; after new seedlings open leaves, apply nitrogen fertilizer or organic fertilizer such as fish meal and bone meal. In order to reduce acidity and prevent rodents and diseases, it is best to soak and ferment soaked soybeans for several months, then dilute them with clean water at about 1:20, and spray topiramate to prevent bacteria and diseases.
