Water Management of Orchid

The water management of orchids is very important, which is one of the keys to the success or failure of orchid cultivation. According to "Linghai Lanyan", "there is a living method of orchid but no board method" water management should be more flexible. First, orchids newly planted in pots must not be drenched with "fixed root water" immediately. The rhizome of the transplanted orchid plant will inevitably be damaged, and it is easy to be infected with bacteria. if it is drenched with water after the pot, it will affect the normal growth of the orchid plant, resulting in rotten roots and withered leaves and even death. Before transplanting, the orchid root should be slightly dried so that it is not easy to break. At the same time, the plant material should be moist and not wet. If the weather is dry after planting, spray water spray on the leaves and it is better to drench the water after three days. Second, it is better to irrigate orchids. Orchids have the habit of "being clean but afraid of dirt". Irrigation and watering can not only meet its water needs, but also remove the residual fertilizer and dirty gas from the plants in the basin, renew the air in the basin, and make its roots absorb nutrients in the air better. If often drenched impervious, so that the plant material in the basin is not dry and not wet (semi-diseased water), it is easy to cause the plant material in the basin to become hot and sour, and the disadvantages of bacterial pest reproduction. Therefore, Yanglan most avoid "semi-sick water". Third, in case of "white rain", you have to drench a lot of water. In the hot summer and autumn season, there will be both sun and rain (white rain). This kind of Rain Water is extremely disadvantageous to the growth of orchids and is prone to disease. a large amount of water should be drenched in time after rain to wash away the acid in Rain Water and the sultry gas in the basin. Fourth, when there are a large number of disease spots on the leaves of orchid plants, we should pay attention not to spray or spray leaf water for the time being, keep the leaves dry and prevent the spread of germs, and spray leaf water only after spraying to control the disease. If it is not controlled, we can only use the method of drenching the plant material in the basin along the edge of the basin. Fifth, it is necessary to implement different water management in different seasons. The temperature is low in winter and spring and the orchid is in the dormant period, the new buds have not yet been unearthed, and the plant needs less water, such as too much water supply, it will hurt the roots and leaves and affect the normal growth of the orchid plant; the orchid plant sprouts in summer and autumn and gradually turns to the luxuriant growth period, and the temperature is high in summer and autumn, and the plant absorbs water and evaporates greatly. therefore, it is necessary to supply more water to meet the needs of orchid plant growth and help to prevent heat and cool down. The water management of orchids can be divided into three steps: "spraying, spraying and irrigation". Generally speaking, the water management of orchids can be divided into three steps: spraying, spraying and irrigation in winter and spring, spraying and irrigation in summer and autumn. Hot weather should be in the morning and evening, while cold weather should be carried out in warmer conditions at noon. At the same time, according to the physiological characteristics of orchids, spraying and spraying regularly to wash off the dust from leaves is more conducive to plant respiration and nutrient absorption, and promote its normal growth. There is no definite method for water management of orchids, which depends on the factors such as orchid basin, plant material, environment, light, temperature, humidity, ventilation condition, variety, weather and orchid plant growth. In particular, it is necessary to have an understanding of the habits and characteristics of orchids and make appropriate water supply. Orchid friends should be good at exploring and summarizing in the practice of orchid cultivation, and the most feasible way is to achieve success.
