Techniques and techniques of hydroponic culture of bird's nest fern

Bird's nest fern is a species of Dryopteris Dryopteris of the family Pteridaceae. Bird's nest fern is a kind of epiphytic fern, which is a perennial shady herb foliage plant. Bird's nest ferns can be hydroponically cultivated, but it has been proved that soil culture can grow better. When hydroponically culturing bird nest ferns, you should usually be familiar with-some key points for maintenance:

The main results are as follows: 1. The single plant with smaller plant should be selected in hydroponic culture, and the pot root washing method should be adopted.

2. During the growing season, water should often be sprayed to the leaves to improve the humidity of the air.

3. Pay attention to the supply of fertilizer. When there is a lack of fertilizer or the temperature is too low, the leaf margin will turn brown.

4, scatter light can, avoid scorching sun exposure, so pay attention to avoid light in summer.

5. You can survive the winter above 8 degrees Celsius.

6. Water can be changed for about 20 days in summer and longer in winter.

Bird's nest ferns are often attached to tree trunks or rocks in rainforests or seasonal rainforests. The bird's nest of the cluster can hold a large number of dead branches and leaves, bird droppings and Rain Water, which are converted into humus and can be used as their own nutrients, as well as other tropical epiphytic plants, such as orchids and other tropical epiphytic ferns. Its ecological habit is that it likes high temperature and humidity and is not resistant to strong light.

Hydroponic plants and flowers to spend the winter attention to winter for our flowers and plants will face a test, according to my experience, the mortality rate of hydroponic plants in winter is higher than other times, almost all hydroponic plants are not as cold-resistant as potted plants. So to protect our flowers and plants from now on, the following brief introduction of some methods, according to their own situation, hands-on operation. Climate profile the weather in November can already be felt in the north. From time to time, there will be strong cold air, occasionally accompanied by the first frost, the rainfall will be much less or stop, and the temperature will drop day by day, gradually moving towards winter. Second, the temperature of hydroponic flowers many friends asked me, "what do you think is the minimum limit for hydroponic plants?" After thinking about it for a long time, I couldn't come up with a definite answer. I can only say that my hydroponic plants can withstand 5 °, and my hydroponic plants below 5 °are not enough. (of most foliage green plants) however, if we want to improve the cold resistance of plants, we should do some cold resistance exercises in advance. Third, since the cold-resistant exercise of hydroponic plants is exercise, first of all, it explains two points: 1, the word "exercise" is a process, and if you can't stick to it, there will be no exercise; 2. The word "exercise" means that there must be a certain limit. Don't overdo it in order to have a good effect. Cold resistance exercise method of hydroponic plants: ① moves hydroponic plants to the sun to strengthen light, pay attention to cover containers with newspapers to prevent sudden rise in water temperature, algae, the effect of "light shear phenomenon" on plants, and round containers also prevent "magnifying glass" phenomenon from burning the roots of plants. Add nutrient solution regularly every week, choose flowering nutrient solution as far as possible, apply less nitrogen fertilizer and more phosphorus and potassium, in order to accumulate nutrients and improve cold resistance. ② moves plants to places with plenty of light to accumulate sufficient nutrients for the photosynthesis of flowers and improve the cold resistance of plants. ③ cold resistance exercise is to put plants outdoors or open windows when the temperature drops in autumn, so that plants go through a process of temperature change, physiologically forming adaptation to low temperature. To exercise the plants, under the conditions that the plants can bear, let the plants accept the exercise of lower temperature as far as possible, and let the plants gradually adapt to the low temperature environment, which is conducive to overwintering. It is more ventilated and windowed during the day, which is consistent with the outside temperature, you can open the window from morning to afternoon, but close the window at night, do not overtrain, it is impossible for plants to adapt to lower temperatures indefinitely, cold-resistant exercise is also impossible for plants to break through their cold-resistant ability, trained plants are only slightly more resistant to cold than plants without cold-resistant training. Don't mistakenly think that my plant is not afraid after cold resistance training. ④ above exercise is carried out under relatively normal temperature, if the plant suddenly encounters a sharp drop in temperature, it should be temporarily moved to the sunny place, close the window, wait for the temperature to rise slightly and stabilize after continuing to exercise, if you always forget to close the window, it is likely to lead to fallen leaves when the temperature drop is large. Remember not to blow the cold wind directly on the plants. Cold-resistant exercise is mainly for winter non-dormant or semi-dormant plants, winter dormant plants do not need exercise. The water temperature of ⑤ water exchange is not easy to deviate too much, otherwise there will be physiological disorders in the roots, which will affect the absorption of water and nutrients by the roots of hydroponic plants, and will also cause defoliation. ⑥ must enter the house at the right time, put it in a warm place or near the heater, and open the doors and windows in the first week to allow the plant to have a slight adaptation process. Do not exercise too much, lead to freezing damage, and do not put it near the heating too early to prevent entering the house too early to affect the accumulation of nutrients or consume nutrients prematurely, which is not conducive to hydroponic plants to pass the winter or grow badly in the coming year. As for the timing, he probably entered the house just before Frosts Descent to spend the winter. ⑦ put the plants into the house before frosting to prevent frost. ⑧ some plants do not need to be trained at all and will basically die in the process of training. For example, Anthurium andraeanum, colored leaf taro and other heat-loving plants will enter the house in November at the latest and freeze to death later. Fourth, the fertilizer and water management of hydroponic plants once a week in October, and the plants are still in the late growth stage. Add less in November, once or twice a month, and most plants are about to stop growing. After December to the beginning of spring, no nutrition, for most flowers, this season, the temperature is very low, most plants are dormant and semi-dormant, generally do not need fertilization. The water level is gradually falling. After all the flowers enter the room in the north, sometimes the heating is very hot, resulting in a very dry room, so we should pay attention to spraying water and moisturizing. Fifth, the cold resistance ability of hydroponic plants is statistically strong: iron tree, one-leaf orchid, hyacinth, calla lily, brown bamboo, cyclamen, dry golden lotus, gentleman orchid, crane orchid, cold water flower and so on. General cold resistance: Dishui Guanyin, green pineapple, hanging orchid, tortoise back, spring feather and other low cold resistance: red palm, colored leaf taro, epiphyllum, arrow lotus, cactus and so on. Six, several methods of hydroponic plant cold resistance 1, wrapping method with double plastic bag film with flowers with bottle cover, you can make their own diy, with wire as a frame, plastic bags as a film, or other better methods. Put it in a place with plenty of light indoors. Take off the mask in time to ventilate when the temperature is high at noon every day. Suitable for high-grade plants, artificial "microclimate" is conducive to maintain humidity, dustproof, cold, branches and leaves more fresh and lovely. 2. In the hydroponic culture of most woody plants, the yellow leaves should be removed, the old leaves should be built, and the long branches should be cut short. The main purpose is to prevent twigs and old leaves, and yellow leaves consume the nutrients accumulated by plants. 3. Pot planting method for many fast-rooting, fast-growing plants can be picked into the basin for the winter, less watering or no watering, no fertilization. In the coming year, we will change to hydroponics. 4. Accumulation method most hydroponic plants are placed at will. In order to spend the winter, they can be put together to give up their temporary beauty in exchange for their lives. When placed, they can be concentrated in a sunny place with enough light. And pay attention to some tips: Xiyang put the front row, Xi Yin put the back row, small front row, big back row, so that you can save space and central heating, which is conducive to unified management and heating. (in some areas where there is no heating, there is no need to install air-conditioning in every home.) Cold exercise (mentioned above, not described) hydroponic plants suitable for this season: by temperature: maintain at about 05 degrees: Hulk, brown bamboo, sprinkle gold, pocket coconut, ivy, white calla lilies, colored calla lilies, rubber trees, geraniums, flower goose paw wood, kidney ferns, iron ferns, etc. The more difficult ones can try: Zhu Jiao, Nanyang fir, Tianmendong. Maintain at about 10 degrees: in addition to the above, rich tree, gentleman orchid, dragon blood tree, pineapple, fish tail sunflower, green apple, spring feather, hanging orchid, tortoise back, dripping Guanyin, taro, crane orchid and so on. Maintain at about 15 degrees: in addition to the above, poinsettia, cyclamen, melon and leaf chrysanthemum, evergreen, variable leaf wood, bird's nest fern, reticulate grass, tiger tail orchid, pepper grass and so on. If it is more difficult, you can try: red cactus, cactus. 7. Clinical symptoms of hydroponic plants in winter generally hydroponic plants will have large and small symptoms in overwintering, such as wilting leaves, falling leaves, withered branches, falling fruits and flowers, but as long as they can survive the cold winter, they will win. Hydroponic plants and flowers winter attention key points for our flowers and plants will face a test in winter, according to my experience, the mortality rate of hydroponic plants in winter is higher than other times, almost all hydroponic plants are not as cold-resistant as potted plants.
