Points for attention in watering orchids

Watering should pay attention to the humidity in the basin, dry method and wet method. The basin is dry but not dry, moist but not wet, which is the standard. Dry and dry is the empty root, wet and excessive is the big black root. Watering is a dry method when it is dry, which will stimulate orchids to sprout, root and bud. Moist but not wet watering is the wet method, which will make the leaf buds, roots and buds that have already grown have enough water to grow rapidly. This is also dry and wet. After sufficient flood irrigation, rest for a period of time, and wait for no gravity water to flow out of the basin floor, that is to say, the water retention rate is 100% (absorbing enough water). When the plant moisture loss is 10%, the plant material will enter a moist but not wet state. when the moisture loss exceeds 40%, it will enter the dry state, this is the best time to water, orchids should be watered in summer when the night is cool and ventilated!

For beginners, water is permeated once a week in winter and every 4 days in other seasons. Watering no law is based on their own environment to judge, the general basin noodles dry 1CM can be watered! The basin dries quickly, as long as it is watered. If the basin is not dry for a long time, it must be bad for the seedlings to grow!

To sum up a few key points, no matter how strong seedlings can be raised, fertilizing can be seen in the sun, don't get used to it! Mainly for weak seedlings, the planting and cultivation of diseased seedlings need some attention, weak diseased seedlings should not be fertilized as far as possible, and watering of weak diseased seedlings should be paid more attention, because weak diseased seedlings have poor ability to absorb water, the new generation is slow, and watering is dry and rewatering. in general, strong seedlings are watered twice and he watered once!

First of all, pay attention to the temperature of the water. Do not use cold water to irrigate in winter. The water temperature should be close to the room temperature. It is advisable to use 8 mi 10 °C. Do not use hot water to irrigate in summer, such as using a water tower to store water, it is necessary to prevent excessive water temperature from harming orchid plants and orchid roots, the water temperature should not exceed 25 ℃ 28 °C, and should not be suddenly irrigated with cold water to avoid damage to orchid plants. In summer, do not water at noon high temperature, generally choose to water in the morning and evening when the temperature is low, and choose ventilation, sunny day watering. Secondly, pay attention to humidity. When the air humidity is too high, it should not be watered or sprayed when it reaches 90 / 100C. During the day, the humidity should be 70mur90. Too much humidity will weaken the role of the root in absorbing water, affect the number of roots, and make the orchid plant lose its original power. Third, we should pay attention to the protection of new buds. During the period of new bud opening, it is appropriate to carry out root watering, and sprinkle and spray water as little as possible, otherwise water irrigation will cause waterlogging rot and cause loss. Fourth, we should be careful not to pour half a section of water. Some people mistakenly think that orchids can not be watered more, so they do not dare to water, often water half of the water, the pot material is wet and dry for a long time, causing the roots to dry up due to lack of water. Fifth, we should pay attention to less static water. When the water tower stores water for too long, the water molecules form chains, and the longer the time is, the more difficult it is to disassemble, and it is difficult to participate in metabolic activities. Sixth, we should pay attention to pouring "soul water". After fertilizing in the evening, the orchid plant can effectively absorb most of the nutrients through the absorption of one night. At this time, it is most in need of water, just like a person drinking tea after a meal, so it needs to be watered with "soul water" the next morning. It has two functions: one is to wash off the fat liquid splashed on the leaves; the other is to wash off the residual fertilizer in the basin to prevent fertilizer damage. Seventh, be careful not to water too often. Orchids have a great tolerance to water, and they are relatively drought-tolerant plants, and a little drying has little effect. On the contrary, it can not be wet, 24 hours of water will cause suffocation, daily cultivation, the vast majority of people love orchid too much, watering too often, resulting in root rot, resulting in plant death. Eighth, we should pay attention to "acid rain". If Rain Water is used, two kinds of Rain Water are not available. One is that acid rain water cannot be used to water orchids. The so-called "acid rain" means that sulfides, fluorides and other acidic substances suspended in the air fall when it rains to form "acid rain". This water must not be used to water orchids; second, artificial rain water, rain bombs contain chemicals, these substances are dissolved in Rain Water, used to water orchids will also corrode the orchid root. Ninth, we should be careful not to spray water at will. "spraying water" is necessary, in addition to replenishing water, it can also keep orchid leaves fresh, which is conducive to orchid leaf respiration and photosynthesis, but it can not be sprayed at will: do not spray in strong sunlight; do not spray in hot weather; spray less when it is difficult to dry without wind; do not spray water with impurities; do not spray when the humidity is too high in rainy days, and so on.
