Six kinds of water that nourish orchids

Water is the source of life, and learning to water is the key to raising orchids. It can be said that after watering, orchid cultivation is half successful. The commonly used water supply methods are irrigation, spraying and soaking basins. Here, the author summarizes some special water supply methods in orchid cultivation into the following six types: 1. Disinfection water. One or three of the commonly used fungicides, such as tocopherol, carbendazim, agricultural streptomycin, potassium permanganate, etc., are used to soak langen and Reed head in disinfectant solution with a concentration of 800 to 1500 times as described by the medicine. the soaking time is generally 20 to 30 minutes, and the permeability can be enhanced by adding vinegar properly. Soaking the orchid root with disinfectant is the first pass to prevent blue disease. in addition to the exuberant mature grass in the garden, the downhill grass, Lanyou gifts and introduced varieties collected by the author should be disinfected before they can be put on the basin. The author's preferred fungicide is potassium permanganate (sold in general drugstores), which has strong permeability and has the effect of both medicine and fertilizer. Disinfection of disinfected seedlings should be treated differently. If you suffer from bacterial diseases such as soft rot, agricultural streptomycin is added to potassium permanganate. If you suffer from stem rot and other fungal diseases, fungal drugs such as tocopherol or carbendazim are added. Orchid seedlings suffering from general diseases are still disinfected with potassium permanganate. 2. Fairy water. The nutrient solution prepared with American root-promoting plant growth factor is commonly known as "immortal water". Fairy water is generally used to soak the orchid root before the pot, the purpose is to promote rooting, promote new buds, promote strong seedlings, especially when covering the old man, the use of "fairy water" has a special effect. The drugs commonly used to prepare rooting-promoting agents are mainly American-made rooting-promoting agents (3000 times solution). In addition, Aidoushou, Guoguang Orchid nutrient solution, Dr. Lan (Orchid Organic essence), Orchid King, High extract and Vitamin B12 are also commonly used fertilizers for the preparation of immortal water. It should be noted that the dilution multiple must be operated strictly according to the instructions of the fertilizer used to prevent errors. 3. Root water. The first watering of newly planted orchids is also called "root water" and "head water". The fixed root water of newly planted orchids must be watered thoroughly, and it is also advisable for some orchids to use the soaking pot method to water the fixed roots. But the timing of pouring root water must be treated dialectically. If the orchid seedling is healthy, and the orchid root has been dried when it is put on the pot, and the wound has been disinfected, then it should be watered immediately after planting; for some weak and diseased seedlings, especially those with bad roots, it is not suitable to water after planting, it should be based on the allocation of wet plant material for water supply, put it in a ventilated and shaded place, and then watered a few days later, so that the wound can heal and recover. 4. Permeable. After the plant material in the basin is dry, the plant material is thoroughly watered, so that the basin soil is completely wet, which is called water penetration. As the orchid proverb goes: dry and thoroughly watered. This is the principle of raising orchids and watering. Watering not only replenishes the moisture needs of orchids, but also adjusts the air in the basin soil, increases the oxygen content of plants, and makes the orchid root breathe more smoothly. In the hot and warm summer and autumn season, driven by transpiration, the water demand of orchid seedlings is relatively increased, so we must often pour water thoroughly and keep the water volume of the basin soil culvert, not too dry. It is worth noting that the dry plant material can not be watered "half of the water", otherwise, because the amount of water is not enough, bring the basin hot air into the basin, it will sulk the Langen, and the unwatered water will become "half-sick water" again. 5. Basin water. In the season when the temperature is not very high, the basin soil dries slowly, often the basin surface has been dry, but the humidity in the basin is still high. In this case, the dry plant material on the basin surface is sprayed with a spray can, which is called basin moistening. After spraying the plant material of three or five centimeters in the basin, it can moisturize the bluegrass Reed head, balance the plant humidity and increase the overall humidity of the Orchid Garden. 6. Resurrection water. After fertilization or medication, clear water is poured or sprayed at regular intervals to eliminate the residue of chemical fertilizer, so as to avoid fertilizer damage or drug damage to Langen and orchid seedlings. This kind of water is called "reviving water", also known as "backwater". Fertilization is better when the basin soil is dry, and fertilize in the evening, wait for the orchid after a night of absorption, the next morning water, such as a cup of tea after meals, refreshing and refreshing. If the basin soil is wet, pouring "soul water" after fertilization is counterproductive, and there is a danger of rotting roots. As for whether to rejuvenate the soul after spraying depends on the situation, the author's habit is: if you spray pesticides, you will spray water after two hours; if you spray fungicides, you will no longer spray water. Because the efficacy of insecticides is fast, and the efficacy of fungicides lasts for a long time, sometimes up to a week, or even more than 10 days, if you spray "soul water" after sterilization, it will counteract the effect.
