Venus flytrap Features
The most important feature is very popular carnivorous Venus flytrap plant , potted applicable sunny windowsill and balconies can also be designed to do the planting trough training, do not have fun .
Venus flytrap is a very interesting carnivorous plants , leaf length at the top resembles a “shell ” of the insect clip , and can secrete nectar , insects break time when there can be a very rapid rate grip, and digestion and absorption. Flytrap unique insect abilities and cool appearance, making it the country \’s most beloved players carnivorous plants !
Venus flytrap form
Sensitive sensory hair belongs to a Venus flytrap vascular plants , complete with roots, stems, leaves, flowers and seeds on the Venus flytrap leaf . Its leaves are the most important and significant parts , with predatory insects function, appearance and red bristles obvious sessile gland site, faces like Zhang teeth claws Xuepentaikou .
Although flytrap can catch insects, but it can manufacture organic nutrients for photosynthesis , so are plants.
roots and stems
Venus flytrap short and underdeveloped root , the main function is to absorb water. Its stems are smaller than normal plants generally connected petiole is not obvious, but in the process of growth and development of the underground will Bulbs, bulbs belong evolution over a metamorphosis stems
Venus flytrap leaves are growing out from the center of the site , are whorled leaves , which was even seat -like growth in the form of clusters . Central grow thin flat or shaped like a wing -shaped leaf disease belongs to the part of the native species of leaf disease is generally flat , such as leaves , because the leaves but like , it is also known as fake leaves. The less the end of the leaf insect disease with a clip , this is part of the leaf will catch insects , there are many positive distribution sessile glands , usually red or the orange , green leaves closer to the place of sessile glands this part is the secretion of digestive juices to the decomposing insects or insect nutrient absorption site. Long green leaves have toothed bristle , bristle base has glands will secrete mucus, is to prevent and get rid of insects lobe bonding. This leaves catch insects have special features , and a special appearance, abnormal leaf belongs in the ” insect leaf”
Because the new leaves are produced from the center , the more so the more older outer leaves . In the outermost petioles sometimes produce new bud . There are two types of petiole flytrap occur : some flytrap petiole slender, up from 7 to 16 cm long, and stretch toward the sky ; others grow short fat Venus flytrap the petiole , and tile in the surface. Folder inside the insect usually reddish color , these colors are mostly digestive glands of pigment , when the plants can receive adequate sunshine , it will promote the generation of plant pigments , these colors from orange- red to red-purple has some catching flies will even produce pigment in the grass outside the digestive glands , thus making whole plants red. However , some flytrap less likely to produce pigment , so the insect inside a folder only showing yellow-green. These phenomena are formed by genetic differences , and therefore has been due to differences in appearance and produce some of these cultivars on gardening.
Venus flytrap \’s insect clip size has been a subject of concern to everyone . In good growing environment, with adequate nutrients, president of the Venus flytrap larger insect folder, but will reach a limit, the Venus flytrap \’s insect clip about the most up to 3-5 cm long . Venus flytrap \’s insect clip size is the result of a long evolution and get the best size to this size insect clip lets Venus flytrap capture most of the insects. If Venus flytrap clips can grow bigger , then far fewer chances flytrap prey because of its large number of small insect body , and a large number of small -shaped insects can never completely closed insect clip escape. Thus , the insect can grow bigger clip is detrimental for the Venus flytrap , is in the process of evolution eliminated .
However, academic or gardening , people have attempted to capture a greater improvement Venus flytrap insect clip , but this work may be very difficult , improved way than the traditional horticultural varieties can achieve our goals. Perhaps membership must be possible from modern biotechnology .
Venus flytrap Venus flytrap summer prescribe the civilized white flowers during early summer to midsummer , when the stems will grow out early each scape has about five to ten buds , are standard corymb , according to the daily order out of white flowers. In principle, opened a commanding per plant stems, if the growth environment and nutrient adequate, sometimes grow out of two stems, mostly under normal conditions is generally five petals and five sepals , petals occasionally six the mutant strain , male , about a dozen core roots, there is a central core of estrogen , has forked stigma .
Venus flytrap plants pollinated with the phenomenon is relatively small, the core reason is because when the male flowers to grow pollen when the female core style is closed state , until the beginning of skewed male core dumped out when stigma will open become forked , and this time is in the state can be pollinated . After the first kind of ambition to grow into mature female core was quite common in the plant kingdom , mainly to avoid the same strain pollination conditions. This flower is generally called jargon as ” core first male flower cooked ” (Protandrous flower)
In addition to the stems , in general, there will be a large part of the higher up the growth of normal stem short and easy to find , petioles and leaves and is affixed to almost grown . This is a feature of carnivorous plants. Because in addition to prey on insects absorb its nutrients , but also for future generations continue to assist the insect pollinators need help , which is part of the so-called entomophilous flowers. It must be supplemented leaves and flowers have to distinguish between the two parts , we can say it is in their nature to natural wisdom.
Venus flytrap cultivation
Venus flytrap prefer good water retention , acidic growing medium . Can be used directly or sphagnum peat soil to cultivation, which is entirely cultivated with only one type of media can be. However, the high price of sphagnum , but life is short, but compared to other growing medium and clean , it is more suitable as sphagnum moss or leaf seedlings cultivation media inserted . Flytrap large strains are more suitable to use lower-cost peat soil . Some peat soil texture is more detailed, and therefore may cause poor drainage completely peat soil only easy water. We can add a small amount of soil particles perlite or peat soil, peat soil and also the sand in a way than a muddy combination. In fact, the origin of the Venus flytrap is grown on sandy land , the use of sand and peat soil blends as from the growing medium is probably the best choice. Because Venus flytrap like acidic growing medium , so the choice to sand quartz sand , silica sand or sand -based ; Do not use sand containing calcium , such as coral sand or shell sand .
Flytrap like humid environment, so you can use immersion method to cultivation, but its depth of immersion Yi Qian level , in order to avoid excessive moisture. From spring to autumn planting medium allows the state to maintain in the wet , but in the winter should make the growing medium is dry , you need to Venus flytrap removed from the water dish .
Venus flytrap need a lot of light . When growing Venus flytrap , placed under the sun as much as possible , or at least in a bright place . If the light is not enough cultivation sites , you must consider the use of artificial lighting.
We can usually be flytrap \’s insect traps to assess the adequacy of illumination . Most native species or horticultural varieties flytrap in the light of adequate cultivation conditions, the digestive gland experience manufacturing anthocyanins, making the inside of the insect traps showed orange to purple colors, and even some red varieties will flytrap whole plant have become purple. However , while some horticultural varieties of whole plant Venus flytrap is characterized by green , even if there is plenty of light , can not make red insect traps , but all green varieties flytrap with adequate sunshine, the color of the plant is tend to yellow -green .
In addition to the lowlight flytrap where red is not red outside the plant as a whole will become more green, this is because the light is insufficient, the Venus flytrap must produce more chlorophyll in order to improve the efficiency of photosynthesis , Thus the plant will become more green . Looks green flytrap , is a serious shortage of light , so Venus flytrap , athletic ability usually insect folder will become slow , and the plants will be getting smaller and smaller , this time, the light must be moved as soon as possible plenty of places .
If the light is too strong , then make flytrap sunburn. Very hot summer often leaves become yellow flytrap seem , then, must be moved as soon as possible shade of sunburn flytrap place .
In general cultivation , the Venus flytrap does not need very humid air humidity, that do not result in a well-ventilated place strong winds will be able to grow normally . Because Venus flytrap cultivation medium has been very wet, water vapor evaporating from the surface of the culture medium to provide sufficient moisture . Unless it is to live in drier areas , or long-term air-conditioned room at the Venus flytrap species , only need to raise the humidity. At this point , you can open the Venus flytrap in the aquarium or plastic tank , you can maintain the humidity of the surrounding air flytrap .
Under normal cultivation conditions , do not flytrap cultivated in a confined space , otherwise ultra-high air humidity would have a negative impact , making Venus flytrap vulnerable to the invasion of pests . Never flytrap in a closed container and exposure to sunlight , otherwise the sun and humidity will bring serious greenhouse effect , the plant heat death . Flower often someone will flytrap hooded plastic cups , the purpose of doing so is usually only prevent customers not touch , or in the cultivation and there is no need to increase the humidity of the air to such a degree .
