Two rotten words in spring and summer

Author: Zi Mo Zi

In the twinkling of an eye, I have been learning to raise orchids for more than eight years. Probably under the influence of the master, he has always liked to cultivate orchids with the method of fine dry cultivation. Now I will talk about how this method is embalmed.

My plant material is very simple, mainly composed of 6 parts of honeycomb coal cinder, 1 part of humus soil (or general pastoral soil, mountain mud), 1 part of bark, 1 part of snake wood strips, 1 part of self-made organic fertilizer or other base fertilizer. From the perspective of the formula, it is relatively vegetarian, and it seems that the fertility is not enough, but it has a good effect on the occurrence of anticorrosive disease. Therefore, I spend a lot of time on creating a cultivation environment, and strive to create a good growth environment for orchids, so that their natural growth, disease resistance will also be enhanced. When using coal cinder, I personally like to mash, the bark chooses the smallest size, snake wood can be slightly larger, mixed according to proportion and used. This kind of plant material is exquisite, the fertility is partial to plain, the capillarity in the basin is strong, the plant material in the orchid basin is from top to bottom, from inside to outside, the dry humidity is quite uniform. Fine plant material and Langen can also be combined to increase the water absorption surface area of Langen. In this way, I can easily maintain the dry humidity of the plant in the case of a small number of watering, so as to achieve the purpose of moistening but not wetting.

Because it is a fine plant material, when planting orchids, you can plant orchids a little deeper, so that the plants can cover the Reed head, which is beneficial to sprouting (buds can only sprout in the dark) and produce strong buds. And after the seedlings grow up every year, the Reed heads are basically kept on the same level, and the uneven humidity in the basin will not cause the seedlings to grow deeper and deeper, and grow smaller and smaller. The road between Miao and Miao is also wide and clear.

When fine plant material is watered, it is easier to grasp the timing. Because the dry humidity of the basin plant directly reflects the situation of the plant in the basin, the timing of watering will not be wrong. Fine planting material is also more suitable for dry cultivation, good capillary use, will absorb the water at the bottom of the basin to the surface plant, the root base will not produce empty root phenomenon because of drying. Every time it is dry, it is watered thoroughly, dry and wet, up and down, the roots of orchids can absorb fresh air, and the plants in the basin are not easy to produce secondary fermentation in warm weather.

In addition, embalming begins in autumn. According to personal observation and practice, most of the seedlings with high incidence of two rot are too much water and fertilizer in autumn and winter, and ventilation is not proportional to it. In autumn and winter, what most people are most concerned about is vernalization and seedling refinement, hoping that in the coming year, they will blossom well, grow more seedlings, and grow strong seedlings. It is precisely this kind of mentality that makes people inadvertently give more water and more fertilizer, coupled with the fact that the plant material is too thick, there is a great difference in moisture between the basin and the basin, and the timing of watering is wrong. It's windy and dry in autumn. Most of the orchids cultivated with coarse materials often dry quickly, but the pots are wet. Winter ventilation must be paid attention to, around noon, ventilation can only open windows in a small area, and then gradually increase the ventilation volume. Must not open and close the window, this temperature difference to the seedling damage, light scorched leaves, serious in the warm winter will occur stem rot, resulting in the whole basin death.

Autumn and winter, my understanding is that the orchid enters the vernalization dormancy period, the water demand is not big, should gradually reduce the water supply, keep the plant material to run mainly. Proper ventilation, mainly small window ventilation, after each watering, according to the weather conditions, can appropriately increase ventilation. But you must not let the cold wind blow directly to the orchid seedlings to prevent frostbite caused by the temperature difference.

In March, strong seedlings can go out of the room first, and the water supply should also be properly controlled, not too wet, and the basin should be dry. When the temperature is too low, move back indoors or put down the plastic film to prevent frostbite. The temperature gradually stabilized in April, weak seedlings, old seedlings can also be cultivated out of the room, during this period, all orchid seedlings must not be fertilized prematurely to prevent the plant material from rotting in the basin, resulting in rotten roots and stems. Usually watering should pay more attention to the difference between water temperature and air temperature. Watering is best when the water source is similar to the orchid basin temperature. I personally think that it is not advisable to use the water temperature difference to promote growth. The temperature difference is necessary, but it is not a sharp temperature difference, but the difference caused by the slow change of temperature in 24 hours a day, which is a physiological stimulus to the plant. The temperature difference in the drama will only hurt the roots and produce two rots.

In May and June, the orchid seedlings gradually unearthed, at this time can slightly increase the water supply, can be appropriate fertilization, and began to pull the sunshade net (according to the local environment, choose the appropriate shading time). When the rainy season comes, if you encounter heavy rain for more than two consecutive days, it is necessary to block the rain, but before the rain protection work begins, you should pay attention to soaking the plant in the basin. During this period of time, the humidifier will be turned on less or not, and the ventilation equipment should be turned on often to give Lanmiao a breath of fresh air. Make rational use of the sunny and ventilated weather to make the plant material in the basin moist and dry quickly and achieve the purpose of anticorrosion from the surface.

In July, sunshade will be strengthened. Specific management has little to do with corruption, so I won't go into details. Combined with my own plant materials, I briefly talked about the cultivation and management in the two-rot-prone period. I hope you will give me more advice and advice.
