How to correctly cause the yellowing of leaves in hydroponic culture of white butterflies and what to do

White butterflies like to grow in hot, humid, loose, fertile, slightly acidic soil. It has strong adaptability and can adapt to different light environments. In the strong light, the stems and leaves are slightly lavender, the leaves are larger and the color is lighter; the flower language of white butterflies is the beauty of simplicity and simplicity.

How to correctly cultivate White Butterfly in Water

1. Selection of hydroponic containers for white butterflies

Hydroponic white butterflies need to choose a suitable container, generally with glassware, plastic or ceramic utensils are also possible, in the container can put some pebbles, fixed plants.

2. the method of hydroponic culture of white butterfly

Water culture white butterfly is actually very simple, the method is to choose white butterfly branches with aerial roots, can be directly planted in water culture, generally white butterfly vitality is more tenacious, rooting will be relatively rapid, about 10 days can sprout new roots.

In addition, potted plants can be transferred to hydroponic culture. Directly use the root washing method, take out the potted white butterflies, wash the roots, cut off 1/3 of the roots, and carry out hydroponic culture. Usually a new root can grow in a week or so.

It should be noted that if it is a hydroponic cuttage, it is best when the temperature is higher than 10 ℃.

3. Maintenance of White Butterfly by hydroponics

White butterfly is a shade-loving plant, it is best to keep it in a place with sound when hydroponic, and it is OK if there is no direct light in front of the window. When breeding, you need to change the water regularly and clean the container.

Changing water can supplement some minerals and nutrients, fill some nutrient solution, and clean up the dirt in the water to make it grow healthily. In order to maintain high air humidity, it can also spray water like the leaves of white butterflies, which has more ornamental effect.

Hydroponic white butterflies will continue to grow, waiting for the white butterflies to grow elegant branches, can be pulled on the wall, in fact, the growth is more stylish.

The cause of yellowing of White Butterfly leaves and what to do

1. Watering often causes the leaves of white butterflies to turn yellow.

Overwatering the white butterfly will cause the leaves of the white butterfly to turn yellow, which is characterized by the fact that the old leaves do not change obviously, and the young leaves gradually turn yellow. when they are overwatered, they need immediate treatment and water control.

2. Drought causes the leaves of white butterflies to turn yellow

Because of the lack of water, the leaves of white butterflies turn yellow due to drought, which is characterized by the fact that the old leaves become withered and yellow first from top to bottom. If there is a shortage of water for a long time, the whole plant will turn yellow, or even die, and it should be watered in time.

3. Fertilization often leads to yellowing of white butterfly leaves.

Because the concentration of fertilization is too high, or the number of fertilization is too many, the leaves produced by fertilization turn yellow; the characteristic is that the young leaves of the plant are relatively thick and shiny, and the leaves are uneven; in such a situation, fertilizer control and watering should be carried out at the right time.

4. less fertilization leads to the yellowing of white butterfly leaves.

Because of the lack of fertilizer, the concentration of fertilizer will be on the low side, and the interval during fertilization will be too long, which will cause the leaves of white butterflies to turn yellow.

Its characteristic is that the young leaves and tender stems are yellow first, and timely fertilization is needed to see this kind of situation, otherwise the yellow leaves of the whole plant will even wither and die; if the flowers are short of fertilizer, do not use a large amount of fertilizer at one time to avoid damage to the root system of the plant.

Rich bamboo symbolizes good luck. People take the auspicious meaning of rich bamboo and plant it at home. There are four common species of rich bamboo, namely, Golden Heart Bamboo, Silver Heart Bamboo, Silver Bamboo, Phnom Penh Bamboo. There are usually two cultivation methods of rich bamboo, soil culture and water culture, the appearance of water culture is more beautiful, and the cultivation is more convenient, so many families choose water culture. In the process of culture, it is easy to encounter the problem of yellowing leaves.

There are many kinds of yellowing leaves of rich bamboo, but it is nothing more than the problems of water, light and fertilization. Since it is to solve the problem of yellowing the leaves of rich bamboo raised by water, naturally consider whether the amount of water is appropriate, too much or too little water will lead to yellowing of leaves. Too much watering will lead to dark yellow and dull new leaves, normal old leaves, yellow-green branches, and poor growth of new leaf buds, which is caused by too much watering. At this time, the rich bamboo should be taken out and placed in a cool and ventilated place, and then put back into the basin after being moderately dried. Pay attention to the amount of water in the basin should not be too much.

The yellow caused by lack of water is different from that caused by too much watering, the lack of water will cause the old leaves to wither and yellow from the bottom up, and then fall off, but the growth of new leaves is less affected and can grow almost normally. At this time, we need to pay attention to timely watering, pay attention to watering enough and thoroughly. If it is not the amount of water, you need to consider whether it is the problem of light, exposure and lack of light will also cause leaves to turn yellow.

Fugui bamboo is a shade-loving plant, strong direct sunlight is easy to cause its leaf tip, leaf edge withered and yellowed. When yellow spots are found in the sunny part of the leaves, they should be moved to a cool and ventilated place in time; rich bamboo likes shade does not mean that it does not need sunlight, it is in a shady environment for a long time, insufficient light will also cause leaves to yellowing and lead to leaf shedding, which can be moved to a suitable light place in time. The problems that lead to the yellowing of the leaves of water-fed bamboo are various, for example, excessive or too little fertilization will also lead to yellowing of leaves and so on.

Conclusion: when faced with the problem of yellowing the leaves of rich bamboos raised by water, we should not only analyze one reason unilaterally, but also analyze it from many angles. Sometimes the wrong position affects not only the light, but also the evaporation of water, thus affecting the amount of water. In addition, it is necessary to judge the specific reasons according to the types of yellowing colors and yellowing parts of the leaves, and should not be dealt with at will, otherwise the problem of yellowing leaves of water-raised rich bamboo can not be solved at all.

The technology and cultivation of hydroponic flowers is the use of modern bioengineering technology, the use of physical, chemical, biological engineering means to domesticate ordinary plants and flowers, so that they can grow in water for a long time, and the formation of a new generation of high-tech agricultural projects. Hydroponic flowers are full of fragrance above and fish swimming below, which is hygienic, environmentally friendly and convenient, so hydroponic flowers are also known as "lazy flowers". Through the implementation of original industrial modern biological improvement technology, it makes the flowers that originally adapted to the terrestrial environment quickly adapt to the aquatic environment through short-term scientific domestication, improvement and cultivation.

First, the technical requirements of hydroponic flowers from the perspective of the cycle of plant growth process, hydroponic flower technology has two technical stages that need to be paid attention to: one is the cultivation stage of seedlings, that is, the hydroponic propagation process, and the other is the nursing stage of plant finished products. that is, the hydroponic culture process in which the user carries out personal operation. Through the above two stages of work, following the correct cultivation rules and paying attention to the problems that should be paid attention to in the breeding process, we can see beautiful, clean, elegant and healthy hydroponic flowers coming into thousands of households. The main contents are as follows: 1. The establishment and methods of hydroponic nursery bed must not leak, and it can be made of concrete or bricked along with thin film, with a width of 1.2-1.5 meters, and the length depends on the scale. It is best to build a stepped seedbed, which is conducive to the flow of water and increase the oxygen content in the water. An electric hot line for heating the feed water is laid at the bottom of the bed to stabilize the water temperature at the optimum rooting temperature of 21-25 ℃. Hydroponics can be carried out all the year round, and the water temperature can be controlled at about 25 ℃ by controlling the instrument. Too high or too low is disadvantageous to rooting. When hydroponics, plant seedlings should be inserted shallowly, water or nutrient solution in the bed 5-8 cm. But in order to keep the plant seedlings stable, clean sand can be put at the bottom. This method can also be called sand-water multiplication. Or drill holes on the styrofoam board, or set up a grid on the water surface, insert the plant seedlings on the board and put them into the water. In the process of rooting, pump is used to pump regularly every day to keep enough oxygen in the water. 2. Preparation of nutrient solution commonly used in hydroponic breeding Water Propagation uses water as the medium, and the medium does not contain the nutrient elements needed for plant growth, so it is necessary to prepare the necessary nutrient solution for plant rooting and seedling growth before transplanting. The selection of the formula of different plant nutrient solution is the key to the success of hydroponics. The formula of nutrient solution varies from plant to plant. A widely used formula of nutrient solution is introduced here. The world's most famous Morad nutrient solution formula: solution A: 125g calcium nitrate and 12g ferrous sulfate. Add the above to 1 kilogram of water. Solution B: 37 grams of magnesium sulfate, 28 grams of ammonium dihydrogen phosphate, 41 grams of potassium nitrate, 0.6g of boric acid, 0.4g of manganese sulfate, 0.004 grams of copper sulfate and 0.004 grams of zinc sulfate. Add the above to 1 kilogram of water. 1) in the process of preparing the liquid, ① weighs all kinds of fertilizers and puts them on clean containers or plastic film bags, as well as plastic film bags spread flat on the ground. When mixing and dissolving fertilizers with ②, strict attention should be paid to the order, and Ca2+ and SO42-,PO43- should be separated, that is, calcium nitrate cannot be mixed with several fertilizers other than potassium nitrate, such as magnesium sulfate and ammonium dihydrogen phosphate, so as to avoid calcium precipitation. The order of fertilizer dissolution in ③ A pot is as follows: first dissolve ferrous sulfate in warm water, then dissolve calcium nitrate, stir while adding water until evenly dissolved; can B dissolve magnesium sulfate first, then add ammonium dihydrogen phosphate and potassium nitrate in turn, stir in water until completely dissolved, boric acid is dissolved in warm water, then add other trace element fertilizers respectively. Two kinds of liquid tanks An and B are stirred separately and then set aside. When ④ uses nutrient solution, take 10ml of A tank mother liquid and dissolve it in 1kg water, then add B tank mother liquid to this 1kg water, then you can use it. 2) the pH of the nutrient solution adjusted by the sample directly affects the existing state, transformation and availability of nutrients in the nutrient solution. For example, phosphate is easy to precipitate in alkaline, which affects the utilization; manganese and iron will also be deficient due to the decrease of solubility in alkaline solution. Therefore, the adjustment of pH (that is, PH) in the nutrient solution can not be ignored. The mixed indicator colorimetric method can be used to determine the PH value. According to the characteristics of the indicator showing different colors in the nutrient solution with different PH value, the PH value of the nutrient solution can be determined. Nutrient solution is generally prepared with well water or tap water. If the PH value of the water source is neutral or slightly alkaline, the PH value of the prepared nutrient solution is similar to that of the water source, and should be adjusted if it does not match. When adjusting the PH value, we should first dilute the strong acid and strong alkali with water, neutralize the nutrient solution with phosphoric acid or sulfuric acid when the nutrient solution is partial to alkali, neutralize it with sodium hydroxide when it is partial to acid, and then add it to the nutrient solution drop by drop, and at the same time constantly determine it with PH test paper until neutral. 3, the problems that should be paid attention to in the process of hydroponics (1), do not use metal containers when preparing nutrient solution, let alone use it to store nutrient solution, it is best to use glass, enamel and ceramic utensils. (2) if tap water is used in the preparation of nutrient solution, tap water should be treated, because tap water mostly contains chlorides and sulfides, which are harmful to plants, and some bicarbonates also hinder the absorption of iron by roots. Therefore, when using tap water to prepare nutrient solution, a small amount of sodium ethylenediamine tetraacetate or humic acid salt should be added to treat chloride and sulfide in the water. If the substrate of hydroponic flower culture technology is peat, the above shortcomings can be eliminated. If the quality of groundwater is poor, it can be prepared with pollution-free river or lake water. (3) in general, the cultivation water in the basin should be changed once in a month or two, just use tap water, but pay attention to put the tap water for a period of time to keep the root temperature stable. (4) hydroponic flowers are mostly negative and neutral flowers which are suitable for indoor cultivation and have their own requirements for light. Negative flowers such as ferns, orchids, Araceae, should be moderately shaded; medium-sized flowers, such as turtle back bamboo, goose palm wood, poinsettia, etc. are not strict on light intensity, generally like plenty of sunshine, can also grow normally in shade. It is very important to ensure the temperature of normal growth of flowers, and the root system of flowers grows well in the range of 15-30 degrees. (5) attention should be paid to distinguish the root color of flowers to judge whether they grow well or not. The whole root or root mouth with proper concentration of light and temperature nutrient solution is white. Please pay attention to forbid excessive nutrient solution and shorten the time interval of adding nutrient solution. (6) in the process of hydroponic flower growth, if water droplets are found to exudate from the leaf tip, it is necessary to appropriately reduce the height of the water surface, make more roots exposed to the air and reduce the proportion of soaking in water. 4. Hydroponic culture technology and flower varieties such as carnation, asparagus, African chrysanthemum, tulip, hyacinth, chrysanthemum, calla lily, paulownia, cyclamen, rose, gladiolus, orchid, evergreen, Manilong, Brazilian wood, hulk, goose palm wood and bonsai flowers (such as Fujian tea, Jiuli incense) and other flowers are very good. Generally available for hydroponic culture are tortoise-backed bamboo, Milan, gentleman orchid, camellia, rose, jasmine, rhododendron, Jinwu, evergreen, violet, Phalaenopsis, inverted golden bell, five-needle pine, Camptotheca, rubber banyan, Brazilian iron, begonia, ferns, palms and so on. And all kinds of foliage plants. Such as Araceae clump taro, silver-wrapped taro, fire crane, Guangdong hanging orchid, silver evergreen; Sedum species of lotus palm, hibiscus palm and other kinds of gentleman orchid, Paphiopedilum, crab claw orchid, rich bamboo, pineapple, silver chrysanthemum, Brazilian wood, ivy, colored leaf grass and so on more than 100 species. Second, how to transform soil-grown flowers into hydroponic flowers in order to reduce the cost and meet the supply of the market, it is a good policy to directly adopt the general soil-cultivated seedlings and transplant them into hydroponic pots. Specific practices are as follows: 1, big seedling planting off the pot: tap the four sides of the flowerpot with your hand, and the whole plant can be removed from the pot after the soil is loosened. To remove the soil, first gently remove the excess soil with your hands (until you can rinse directly with water). Washing: rinse the soil or matrix that sticks to the root with water. Cut the planting basket: if the head of the plant is too large and the aperture of the planting basket is too small, the hole of the planting basket needs to be enlarged to facilitate planting. Add nutrient solution: add the prepared nutrient solution to the container. Large seedling planting: insert the root system of the plant from the planting basket and be careful not to hurt the root. Fixed: fixed with sponge, hemp stone or Yuhua stone (other solids can also be used). Finished product: check whether the finished product is fixed. 2. The colonization of small seedlings is much easier than that of large seedlings. The main steps are as follows: potted seedlings: small seedlings are generally no more than 8 cm. Wash the roots of the seedlings: remove the seedlings directly from the basin, wash the roots in water, and be careful not to hurt the roots. Seedling planting: insert the root system directly from the hole of the planting basket and fix it with stone. 3. The blending user of the nutrient solution can purchase the preparation from the chemical reagent store according to the formula provided in this paper. At the same time, according to the local fertilizer source, urea and other fertilizers can be used for preparation research, and then used in production after gaining experience. The preparation principle of other fertilizers is that the total concentration is controlled at 0.1-0.2%. 4. the main points of transplanting flowers hydroponically cultured flowers must control the water level, which should be low rather than high. The root can be in the water, or even less (keep the adaptation period for one month, and then increase the amount of water later). In the process of hydroponics, when water droplets appear at the tip of flowers, the water level needs to be lowered appropriately, and direct sunlight should be avoided at the beginning. 5. Judging the deficiency of nutrient solution in the hydroponic flower culture technology of flowers and plants, the lack of certain nutrient elements will produce physiological obstacles, affect growth, development and flowering, and even lead to death. Therefore, it is necessary to adjust the nutrients of the nutrient solution in time. Nitrogen deficiency: slow plant growth, yellowing leaves and serious leaf shedding. Phosphorus deficiency: often showing abnormal dark green, sometimes gray or purple spots, delayed ripening. Potassium deficiency: dicotyledonous leaves are green-deficient at first, followed by scattered dark necrotic spots; in Monocotyledons, the tip and edge cells of leaves first necrosis, and then expand downward. Calcium deficiency: significantly inhibit the development of buds and cause root tip necrosis, the plant is short and has dark wrinkled leaves. Magnesium deficiency: chlorosis occurs between the veins of old leaves at first, blossoms late, becomes light spots, then turns white, and finally turns brown. Iron deficiency: there are obvious symptoms of green deficiency between leaf veins, which turn into burning in severe cases, similar to magnesium deficiency, except that they usually occur on tender leaves. Chlorine deficiency: the leaves wilt first, then become chlorine deficient or necrotic, and finally become bronze. Boron deficiency: can cause physiological disorders, showing a variety of symptoms, but mostly for the death of the apical meristem of the stem and root. When the above nutritional deficiency occurs, it should also be carefully checked. Because some are not necessarily caused by lack of nutrition, it may be due to inappropriate pH, and some are caused by the lack of several elements at the same time. We must find out the situation and prescribe the right medicine to the case.
