How to water orchids in summer

First, the successful planting and breeding experience of the elders of Jiaowang in learning.

1. Lao Bai: Lanyou all know that if the humidity is high, the seedling rate is high, and the new grass grows fast. how can the platform without a humidifier improve the humidity? it can be increased by more watering.

two。 Zhu Dayong: the humidity in the general environment is very low, and things like adding water plates are of little use. Cultivate the roots well, even if the humidity is very low.

3. Watch chess: grain plant nourish orchid, rather wet than dry. Especially in the high temperature season, I observe the rotten roots of the transparent basin, the bottom of the basin is wet every day, and the blue root grows well. The basin noodles can be watered when they are dry.

4. Weichang: if you want to have a good root system, you can't lose the light. Light is the driving force of root development. The stronger the light, the more water transpiration on the leaf surface, the more nutrients are consumed, which promotes the root system to develop in order to increase the amount of water and fertilizer absorption, just like people, the amount of exercise is large, the amount of eating and drinking water is also large, as long as the nutrition can keep up, eat and drink enough to sleep well. It's hard not to be strong. If you understand this principle, it is not difficult to find the most suitable way of management for your environment. If your fertilizer is too fat, then, please increase the light as appropriate; if the plant material is too fine and has strong water retention, then also increase the light as appropriate; on the contrary, if the plant material is too thick and light, please reduce the light appropriately, and the water supply can be slightly less; if the plant material is coarse and the environmental light is strong, it is necessary to increase the amount of fertilizer and water, so as not to cause thin and yellowing leaves due to excessive consumption of bluegrass.... no, no, no.

Based on the valuable orchid cultivation experience of your predecessors, the conclusions are as follows: in order to raise orchids on urban balconies, due to the dry climate, it is necessary to water more in summer in order to increase environmental humidity and supplement the loss of water in orchids. Orchids can grow normally and sprout more, but the premise of more watering is to cultivate good roots. if the roots are rotten, there is no way to absorb moisture, and it is useless to water orchids more. Depends on the type of orchid, the intensity of light, planting materials, to determine how to fully supply orchid water and fertilizer, orchid growth can be exuberant.

Second, in the dry balcony in summer, if you raise orchids with organic materials, you must sterilize regularly in summer to prevent rotting roots, and it is not very suitable for the method of watering and wet raising at noon, otherwise, the chances of rotting roots will be greatly increased. If there is no regular pesticide sterilization, it is best not to use organic fertilizer, because organic fertilizer depends on bacterial decomposition, in high temperature and humidity environment, it is easy to cause two rot, and the use of 20-30 tablets per pot of Haokangduo can not hurt the roots and leaves. As for the use of other orchid chemical fertilizers, it depends on the humidity and temperature of the environment and the types of orchids. As long as there is no fertilizer injury, the orchids grow well is the correct method of fertilization, and of course, they should also be observed with the eyes. For example, the leaves have not yet opened after the new buds are unearthed. To observe the upper edge of the leafy pants after fertilization, if there is a blackening phenomenon, it shows that the fertilizer is too heavy, because this place is easy to accumulate water and fertilizer. After the balcony dries and water evaporates, the fertilizer will be left here. When the concentration is high, the edge of the leaf trouser will be fat and black. In addition, if the root and root tip are brown or black, most of the material is too fat or the fertilizer is too heavy.

Third, whether to water at noon is not the key point. The key point is whether the orchids in summer are short of water on the dry balcony. If the orchids grow normally and do not grow up, of course, they do not need to be watered at noon. Zhu Chunyuan's predecessors raise orchids in large pots and water them once every two days in summer. They can grow two generations a year and grow well, so naturally they do not need to be watered at noon. Therefore, if the new buds of orchids stop growing in summer. The orchid leaves are twisted and deformed, which is a sign of lack of water. It is necessary to water at noon. If most of the new buds of orchids do not grow at noon, it can only prove one thing, that is, your environment is not suitable for orchids. Only build a greenhouse to continue to grow orchids, or give up orchids, because noon watering is the last way to dry balconies. If this trick has been tried, orchids still can not grow normally. Then there's no other way.

Fourth, I grow orchids with broad leaves and small roots, which are less resistant to drought, so they are watered at noon to supplement the lost water, so their growth conditions are naturally better, but some orchids have thin leaves and more drought-tolerant roots. for example, as long as Huilan and Sijilan grow normally, they naturally don't need to be watered at noon.

Fifth, the elder Zhu said that not to take medicine on a list is to prescribe the right medicine to the case, and do not always take medicine when you are cured. Watering at noon is only to solve the problem of water loss of orchids in the dry environment in summer, causing growth to come to a standstill. After the beginning of autumn, the temperature drops, and the demand for water in orchids decreases. Of course, there is no need to water at noon, but to slowly reduce the supply of water.

6. Raising orchids on a dry balcony in summer, adequate water supply is the key to orchid growth. If pesticides are not used for sterilization, it is necessary to use inorganic matter to plant and use chemical fertilizers. If organic matter is used to plant and use organic fertilizers, it is necessary to sterilize orchids regularly in summer. Of course, the temperature of the environment also has a great impact, so there is no law for orchid cultivation. Everyone should choose a method suitable for the environment. Orchids can grow, blossom and reduce diseases, which is the correct way to raise orchids.

7. The orchid has little water loss in the humid environment, so it is necessary to dry and water the orchid. In the dry environment, the orchid loses a lot of water at high temperature, so the orchid can grow normally only when the orchid is wet and watered, and the orchid is dry in the high temperature and dry environment.

Eighth, the humid environment is not suitable for watering at noon, the stagnant water in the bud core is not easy to dry, and under the condition of high temperature, it will cause rotten bud, so it is more suitable to water it when it is cooler in the evening. In a dry environment, the stagnant water in the bud core will dry 10 minutes after watering. Therefore, environmental factors should be taken into account in watering at noon, and we must not stick to when to water.
