Our commonly known as the camphor tree, each family uses its leaves to distillate oil, and I don t k

We locals generally cut twice a year, in summer and winter. Its branches and leaves to distill the oil.

The smell of camphor is avoided by insects, so it can be used to put it in the closet or somewhere to prevent insects.

Camphor tree, also known as camphor tree, camphor, camphor, etc., is one of the four famous trees in the south of the Yangtze River.

In this case, there must be bugs, which are a kind of bugs like the commonly known tide bugs. It is recommended that you buy some dimethoate or dichlorvos and spray it on the roots and trunk of the tree. At about a meter above the ground, use scotch tape to spare a few laps to prevent insects from climbing up.

First of all, is it true that there are no worms? You can pinch off the leaves whole, from the root of the petiole. New ones can grow.

Cut off the leaves with the bugs, and he will grow new ones on his own, killing the tree with insecticides!

The leaves are leathery, alternate, pinnate veins.

The leaf size and vein system vary greatly, bai

Generally, du is oval or oblong-oval

shaped, 6-12 cm long, 3-6 cm wide, ventral smooth, back-pinkish-green, apex acute, base wedge-shaped or broadly wedge-shaped, also pinnate, veins glandless, lateral veins 4-5 on each side, petioles long cm.

Leaves thin leathery, ovate or elliptic-ovate, 5-10 cm long, 3 5-5 5 cm wide, apex short pointed or near caudal tip, base rounded, 3 veins from the base, the first or second pair of lateral veins near the base of the leaf are long and prominent, the back is slightly powdery, and the axils of the veins have glandular spots. The panicles are born in the leaf axils of new branches.

Camphor leaves are the leaves of the camphor tree, some smaller and some larger.

The camphor tree is not very tall, but it is very stout. The foliage is luxuriant, and the dense foliage is shiny green, and the almost oval green leaves are dark and light: vermilion, tender green, dark green.

The above is the talent of the little griffon, which one.

Okay? The first is stubborn, the second is brave, the third is bold, the fourth is withdrawn, the fifth is anxious... Plus a withdrawn personality.

Together with the above five kind-hearted people, help me see which one is better... Thanks thanks... The little griffin is talented, stubborn, brave, bold, withdrawn, anxious, noisy, and withdrawn, which one is more worth practicing, everyone can help.

Worker wow wqet spoof advance Mrs. FTAW is too annoying.

The leaves are leathery, alternate, pinnate veins, large and small in leaf shape and vary greatly in vein, generally elliptical or long.

DAO elliptical gyrus ovate, 6-12 cm long, 3-6 cm wide, ventral surface smooth, back-palate-green, apex acute, base wedge-shaped or broadly wedge-shaped, also pinnate, veins glandless, lateral veins 4-5 on each side, petioles cm long.

Leaves leathery, alternate, pinnae-veined, leaf-shaped.

DU size and vein system change.

The zhi difference is large, and it is generally elliptical.

DAO round or oblong oval.

Cinnamomum camphora is an evergreen tree in the Lauraceae family. The flowering period is May, and the fruit ripens in September and November. It likes full sunshine and is slightly tolerant of semi-shaded, warm and humid environments; Not tolerant to drought and severe cold.

The camphor tree has beautiful branches and leaves, the tree is large and thick, and it is evergreen and fragrant in all seasons. Its wood is excellent, and the branches and leaves can extract camphor and camphor oil, which is an important raw material for chemical and pharmaceutical purposes.

【Habits】Camphor trees like light and are slightly shade-tolerant; It likes warm and humid climate, is not cold tolerant, has no strict requirements for soil, and is more resistant to water and moisture, but is not tolerant to drought, barren and saline-alkali soil. The taproot is well-developed, deep-rooted, and can resist wind. Strong germination and resistance to pruning.

The growth rate is medium, and the tree is large like an umbrella and can provide shade and shade. It has a long survival period, can grow into hundreds of thousands of years of towering ancient trees, and has a strong ability to smoke and retain dust, conserve water sources, stabilize soil and prevent sand and beautify the environment! In addition, it has the ability to resist sea tidal wind, smoke and dust and toxic gases, and can absorb a variety of toxic gases, which is more suitable for the urban environment.

Very good, very good to write words as they are.

A person, flames, flaming red lips one by one noble light retro feeling.

To refine it into oil, it depends on whether it is a leaf or a branch or a stem; Different structures of oil extraction methods are different, with the simplest leaf oil extraction method is the aluminum pot steaming and then cooling; It is also the most widespread practice in rural areas at present.

With absolute ethanol as the solvent, the camphor leaves were cut into 1cm size, 110ml of absolute ethanol, extracted with Soxhlet extractor for 100min, and extracted twice continuously. References may be made,** below.

Camphor tree. Also known as camphor, it is the most important tree species for refining camphor and camphor oil. The camphor oil content can be divided into 3 types:

Cinnamomum camphora (mainly containing camphor), linalool (mainly linalool) and camphor (mainly containing eucalyptol and terpineol). Cinnamomum bodinieri. Yunnan camphor (.

Camphor oil is mainly composed of various terpenoids. Generally, multi-tower continuous vacuum distillation is used, combined with freezing, sublimation and other processes to prepare refined camphor and various essential oils (such as eucalyptol, linalool, terpine, safrole) and by-products (such as white camphor oil, red camphor oil, blue camphor oil).

It is a spice and an important chemical raw material obtained by refining and distilling camphor leaves or small branches, which is used in medicine, cosmetics and other industries.
