How to cultivate cobra bottle grass

Cobra bottle grass is a very well-known insectivorous plant species, named for its resemblance to cobras, and is the target of many players' collections. The left and right sides of their caps stick together to form a spherical top, making the whole bottle almost sealed. There is a sunken gap between the spherical bottle cap and the bottle body. There are many white markings on the caps and bottles that lack chlorophyll, through which sunlight can be shone into the trap bottle. Insects (mostly ants) can enter the bottle through the slits. Once inside, they will be confused by these white spots, mistakenly thinking that the white spots are lost in the trap bottle for □, and finally fall into the digestive juice and be digested.

Matrix: peat, sand, water moss, peat, perlite, coconut shell and so on.

Watering: need to use soft water irrigation, such as Rain Water, distilled water, reverse osmosis deionized water and so on. Tap water in some areas contains a lot of minerals (especially calcium salts). These calcium salts will be deposited, killing plants. This is because most insectivorous plants have adapted to poor acidic soils, so they are extremely calcium-avoiding plants, so they are sensitive to nutrients in the soil.

Temperature: resistant to cold and heat, especially to keep the root cold, there should be a large temperature difference between day and night; it can survive between minus 10 degrees and 30 degrees, and 15 to 27 degrees is the most suitable temperature for its growth. Like strong light, in the temperature is not too high, can accept the sunlight, the top of the plant will show a red net pattern, very beautiful.

Diseases and insect pests: vulnerable to aphids or pink scale. Smaller hazards should be removed by hand, while larger hazards should be treated with pesticides as appropriate. Isopropanol is an effective insecticide against scale insects. Perazinone is also a broad-spectrum insecticide that most insectivorous plants can tolerate. Malathion and acephate are also suitable for insectivorous plants.

Although pests are a problem, the biggest problem is Botrytis cinerea. It develops in a warm and humid environment and becomes a serious problem in winter. Put it in a cool, well-ventilated environment and remove the diseased branches in time, which can inhibit the development of Botrytis cinerea to a certain extent. If it fails, fungicides should be used as appropriate.

Cobra bottle grass Darlingtonia californica Cobra bottle sketch guide: how to grow cobra bottle grass / cobra bottle grass how to breed cobra bottle grass business card cobra bottle grass Darlingtonia californica cobra bottle grass introduction of cobra bottle grass (scientific name: Darlingtonia californica) is one of the genera of the bottle grass, is an insectivorous plant, mainly distributed in northern California and Oregon. Cobra bottle grass is a very well-known insectivorous plant species, named for its resemblance to cobras, and is the target of many players' collections. The leaves of cobra bottle grass have two types. The leaves are rosette-shaped, and each adult growing point is composed of 3 to 14 leaves. The leaves of the seedlings were simple tube-shaped and the ends were acuminate in 2 to 3 years. Young leaves are generally 1 to 3 cm long and are reddish green to red. After that, the leaves of Naja naja atra changed to the mature state. Mature leaves have the function of catching insects, 20 to 80 cm long, hollow, with tubular in the lower part and spherical in the upper part and dilated forward. There is a 10 to 20 mm cavity at the bottom of the leaf protuberance, which is the only opening in the leaf. The edge of the bottle mouth bends inward, forming a shape similar to the mouth of a lobster cage. The mouth of the bottle is linked to a binary fishtail appendage. There are nectaries on the back of the appendage and around the mouth of the bottle. The globular part and the upper end of the tubular part of the leaf are covered with a large number of irregular translucent white markings. The inner surface of the globose part of the leaf is glabrous, smooth and waxy. Tubular part lower 1/3 inner surface with downward hairs, 2 to 8 mm long. Morphological characteristics of cobra pitcher grass is a tufted perennial herb. The stem often grows along the surface with creeping branches, and the stolon is 20 to 80 cm long. Stolons can develop into independent plants. The root of cobra bottle grass is brown and 10 to 25 centimeters long. The leaves of cobra bottle grass have two types. The leaves are rosette-shaped, and each adult growing point is composed of 3 to 14 leaves. The leaves of the seedlings were simple tube-shaped and the ends were acuminate in 2 to 3 years. Young leaves are generally 1 to 3 cm long and are reddish green to red. After that, the leaves of Naja naja atra changed to the mature state.

There are nectaries on the back of the appendage and around the mouth of the bottle. The globular part and the upper end of the tubular part of the leaf are covered with a large number of irregular translucent white markings. The inner surface of the globose part of the leaf is glabrous, smooth and waxy. Tubular part lower 1/3 inner surface with downward hairs, 2 to 8 mm long. Each mature plant of cobra bottle grass produces only one flower in spring. Sepals yellowish green, lanceolate, 3 to 5 cm long. Petals dark red to purple, lanceolate to oblong, 2 to 3 cm long, glabrous, with transverse veins. Ovary located in the center of the flower, green, 5-loculed, 1 to 2 cm long. Stigma star-shaped, protruding from the end of ovary. Stamens 15 to 25, distributed around the base of the ovary. Anthers 2 to 3 mm long, oblong, yellow. The flower stem is 25 to 90 cm long, usually 10 to 25 cm higher than mature leaves. The florescence is from April to June. 1 to 2 days after flowering, the stigma can accept pollen, and the pollen begins to disperse. After 6 to 10 days, the petals and stamens wilted and fell off. If the pistil is pollinated successfully, it will continue to expand and form a seed pod 3 to 4 cm long after 8 to 14 weeks. The seed pod is apically lobed, containing 40 to 300 light brown seeds 1 to 3 mm long. Seed surface with irregular spikes. Ecological habits of cobra bottle grass survival temperature:-10-30 suitable temperature: 15-27 cultivation substrate: peat, water moss, perlite, sand and other cobra bottle grass cultivation techniques need to use water with low mineral content (such as Rain Water, pure water, etc.); resistant to cold and heat, especially to keep the roots cold, there should be a large temperature difference between day and night Like strong light, under the condition that the temperature is not too high, can accept the sunlight, the top of the plant will show a red net pattern, very beautiful; if you need fertilization, you can spray more than 1max 5 of the indicated concentration. Planting method Cobra pitcher grass is one of the insectivorous plants that are difficult to cultivate. It requires higher daytime temperature and lower night temperature. Its native place is a swamp or river bank that has cold mountain springs flowing into it all the year round, and the root can keep a low temperature all the time. Therefore, the best simulation method in cultivation is to cultivate in cool pure water. Ice can be placed on the surface of the soil to cool down when the weather is hot. In a high humidity and warm environment, plants can be given sufficient sunshine; if the humidity is low or the range of change is large, a little shade is needed. It is very difficult and slow to plant cobra bottle grass from the seedlings, so it usually propagates with its stolon in late winter or spring. Usually from the Spring Equinox to late spring, many small teeth grow on the stolon internodes. Cut the stolon into several segments, each with some roots. Then put these stem segments on cool, damp broken water moss to keep the environment bright and humid. The bud development can be seen after a few weeks. Like other insectivorous plants growing in temperate regions, cobra bottle grass needs to be dormant in winter in order to survive for a long time. The plant stops growing for 3 to 5 months in winter. Until near spring, mature plants grow a single flower and several large insect bottles a few weeks later. It will continue to grow insect bottles throughout the summer, but its size is much smaller than that in spring. Many growers have successfully cultivated cobra bottle grass and found three variants: all-green, all-red, red-green. The wild cobra bottle grass is all green in general sunlight and red-green in strong light. The distribution area of cobra bottle grass is mainly distributed in northern California and Oregon. Biological characteristics of cobra pitcher grass insecticidal mechanism the fishtail appendage of cobra pitcher grass secretes a large amount of molasses and gives off a strong smell. Insects such as wasps and flies are attracted to the mouth of the bottle by the smell. Insects crawling along the nectaries may be introduced into the bottle, and the transparent markings in the bottle will confuse the insects and make them mistake them for an exit and be trapped in the bottle. Due to the waxy top of the bottle and the middle and lower part with downward hair, the insect will gradually fall into the digestive juice at the base of the bottle. After that, the body is digested and the plant can absorb the decomposed nutrients. Other species with similar trapping mechanism are Sarracenia psittacina, Sarracenia minor, Nepenthes klossii and N. aristolochioides. The cobra bottle grass is one of the three species of bottle grass in America. The trap bottle does not collect Rain Water, but absorbs water through the root and secretes it into the trap bottle. It was thought that the insect bottle of cobra bottle grass did not secrete digestive enzymes, but had to rely on symbiotic bacteria and protozoa to break down prey into absorbable nutrients. But later studies have shown that cobra bottle grass can secrete at least one proteolytic enzyme to digest prey. The absorption of nutrients by inner wall cells of insect trapping bottles from digestive juice is similar to that of root cells from soil. However, there is still a close and mutually beneficial relationship between cobra bottle grass and some animals and microorganisms. The Botanical History of 1841, botanist J. D. Brackenridge discovered the cobra pitcher grass in Mount Shasta, California during an expedition to the remote west. [1] in 1853, John Torrey described the genus Cobra and named it after William Darlington.
