Plant material and upper basin for raising orchid on balcony

The quality of planting material is the key to the success or failure of raising orchids on the balcony. With the continuous development of modern orchid culture technology, there are coarse plant method, fine plant method, water culture method and air culture method. Taking a comprehensive view of the various methods, we can see that water and gas are the key to growing orchids. Most of the orchid cultivation on the balcony does not have the professional conditions, and the above methods are not completely suitable for the orchid cultivation on the balcony. The orchid cultivation on the balcony should be based on the ventilation of the balcony and the breathability of the orchid basin to prepare suitable plant materials for the environment. The ratio of plant materials used by the author is as follows for reference: 1. Perlite 35%. According to not 10%. Cinder 15% (crush honeycomb cinder, maximum peanut kernels, remove unburnt black charcoal, rinse and dry): 4. Pine needles 20%, spare after exposure and disinfection; 5. 20% soil, choose pond mud or paddy field mud to dry and crush the largest soybeans. The viscosity of pond mud and paddy field mud is high, and the fine soil particles have strong adhesion, so it is not easy to flow with the water during watering, but the base plant structure is changed, and the larger particles are not easy to be pulverized in the presence of water. The humidity of the plant can be adjusted when the basin is dry. Mix perlite, sawdust, slag and pine needle and spray wet, then add soil and mix well. After the plant material is prepared, its performance should be tested. the method is to pot according to the procedure of cultivating orchid plant, pour through water and put it in the ventilated place of balcony, pour out the plant material for four days in winter and two days later in summer to check the soil moisture in the pot. at this time, it is better to have about 20% water in the plant material, that is, it is better to see that it is a little dry, and you can use your hands to put it together. If it is too dry, you can appropriately increase the rental grain mud, and if it is too wet, you can appropriately reduce the proportion of fine grain mud. This is an important basis for daily watering and can not be ignored. After the plant material is prepared, the acidity and alkalinity of the plant material should be tested. If there are no special circumstances, this kind of plant material is basically available. If there is any discomfort, it can be adjusted appropriately with rice vinegar or plant ash.

Before potting the orchid plant, all the roots, stems and leaves of the plant should be washed with tap water, which has a certain effect of disinfection and sterilization. After cleaning, cut off the root system with focus, spray the whole plant with chlorothalonil and virus Bike according to proportion, and prepare for planting in the shade. According to the size of the flowerpot, choose the mineral water bottle of the right size to intercept the height of the orchid pot lstroke 4, open the peanut kernel size holes around and at the top, place them in the center of the bottom of the orchid pot, fill them with broad bean-sized foam blocks to the 1gamma 3 places of the orchid pot, cushion 2mur3cm broken bricks, generally speaking, leave 8rel 10cm growth space in the upper part. After the bottom is padded, the finished orchid plant is placed in the center of the flowerpot, and the depth of the top of the Reed head is slightly higher than the surface of the basin mouth. After the plant material is full, the plant material should be built into a semicircle, and the top of the plant material should be more than half of the Reed head. The edge should be 2 cm deep, and the surface of the basin should be covered with broken bricks along the slope and gently compacted with the palm of the hand. After the orchid plant has been planted, put it in a shady ventilation place, pour it thoroughly after 5 days, and water it again after 10 days and bring it into normal management. Wet plant planting does not need to be watered, which can avoid accidental damage to the orchid root and bacterial infection caused by watering. (song Mingyuan)
