Key techniques of water control in orchid cultivation

In orchid cultivation, watering is the key, as the saying goes,"watering three years of work", such as orchid watering without thinking, do not grope, that is, thirty years will not have three years of work, so say water well, many problems can be solved. The first watering should be suitable for orchids and understand the growth characteristics of orchids; the second is according to the characteristics of orchids, combined with their own cultivation environment and plant watering; the third is according to the different growth periods of orchids watering. In fact, only the first point, in the final analysis, is consistent with the growth characteristics of orchids. Most of the friends who just started raising orchids are afraid that orchids will die, watering the pot surface as soon as it is dry, or spraying water often to the orchid leaves, and soaking the bottom of the orchid pot in a tray with water, so that the pot is too wet for a long time, affecting the respiration of the roots, making the roots necrotic, and sometimes forming a "water bacon" shape. When the pot is dry, the roots will be empty, and it is not easy to transplant the pot; it is also easy to make harmful bacteria multiply rapidly, and orchids get sick; Some orchids look full of seedlings, is not flowering and so on, this is due to watering too often caused by various problems. Orchids in the growth process of a year, most of the time the water demand is not much, if it can withstand the pot dry, watering will basically pass, do the pot dry, we must control water to orchids, control water is to control water to orchids, also known as buckle water, but in the process of orchid growth, not long-term control of water, the wet or wet, the control of water when you have to control water, roughly speaking, must control water in the following several periods:

1. Water control during orchid flowering period. To open a good opening product, in addition to raising strong orchid grass, but also master the water control during flowering period, when the orchid flower scape is elongated and the stamen is to be peeled off, water the orchid once, and then do not water until a few days after the flower is cut off. In this way, the more the flowers open, the more energetic, the petals are upright, the petals are not easy to turn back and twist, the outer petals are elongated, the long opening and falling shoulders of the accessory petals are controlled, the degree of opening the skylight and tongue will also be reduced, and the flowering period will be long. Therefore, the flowers participating in the orchid exhibition are good for a long time. Water control is very important. The flowers participating in the orchid exhibition were awarded a gold medal on the first day, and the flowers on the second day were not even awarded a bronze medal. In addition to the flower protection relationship itself, the most important thing is not to give water control. For the flowers with poor flower protection, water control should be done in advance.

2. Water control during the growth period of new seedlings. Now because of the complete natural breeding of orchid friends are not many, so the budding period sooner or later more, so can not be determined in a few months to a few months. Orchids in the germination stage to keep the pot wet, in order to let the new buds smoothly up and more germination, but to the new seedlings out of the pot after the opening, to gradually control the water, from wet to moisten-based, can take small water, large water, empty pot interval way to control water, small water is watering when the bottom of the pot stops watering, large water is the top of the pot, bottom leakage, watering thoroughly, can also be back and forth several times, empty pot is a short time of water control, so that the pot to a drier degree, Depending on the wet condition of the basin soil, it can be carried out alternately with large water, small water, small water, empty basin, large water and small water. Small water can be continuous, large water should not be continuous, and empty basin is in front of large water. Through this semi-control of water, new seedlings can be promoted to grow roots, so that she can support herself, increase the development of new seedlings, and lay a foundation for the growth of new seedlings.

There was a plum rain season during the growth period of new seedlings in Jiangnan. By semi-controlling water, the probability of stem rot, soft rot and other diseases of new seedlings was greatly reduced. When the plum rain ends, after the lunar summer solstice, most new seedlings grow to half size, the weather is gradually hot, the degree of water control is gradually increased, dry can withstand the heat of the environment, orchids can experience 35℃ or even higher high temperature when they are dry, if they are too wet and not ventilated when they are high temperature, various problems will come one after another. To avoid watering at high temperature, the period from wet to moist in the basin should also be spent at a lower temperature. Therefore, Lanyou's summer watering is arranged at night when the temperature is lower. When the temperature rises the next day, the basin is not too wet. Through my observation, orchids can still grow rapidly at a temperature of 32 ° C, so high temperature is not afraid, the key is to control water and ventilation, both of which are equally important. If there are air conditioning and other cooling facilities Lanyou, can implement semi-controlled water state, a summer, there will be a second generation of new seedlings out.

Third, orchid flower control water. From the bud opening gradually control water, spring orchid will have the first batch of flower buds out, earlier flower buds appear in April, this is very normal, sometimes flower buds from formation to flowering lasted nearly a year, late management properly, completely normal flowering. However, most of the spring orchid flower buds are formed after August, that is, after the beginning of autumn in the lunar calendar, because after the beginning of autumn, the temperature is still high, but the air begins to dry, you do not control the water, the basin will also form the effect of controlling the water, if you deliberately control the water, you can make the orchid more flower buds, promote the flower control water is different from the general water control, such as an orchid is not easy to flower, to control the water is very dry, so that the orchid "feels" there is a sense of crisis, poured with small water and then control the water, so many times, there is a satisfactory effect. Don't be afraid orchids will dry up, but weak, sick seedlings can not do.

Cymbidium flowers, most of the water control effect is better. This summer and autumn season, although the new seedlings are big, but the leaves are still tender, plus autumn tiger, the temperature is still high, orchid leaves are prone to black spot disease, through water control can also control the occurrence of black spot disease, so promote flowers and prevent diseases kill two birds with one stone.

IV. Orchid water control in winter. Winter water control is mainly because orchids grow slowly in winter and require very little water. It can also prevent freezing and freezing due to low temperature in the basin, so it is no longer cumbersome.
