Identification of raw herbs
Millettia Pieces
Character identification
The vines are flat cylindrical, slightly curved, 2-7cm in diameter. The surface is gray-brown, sometimes grayish-white spots are visible, and the cork detachment is reddish-brown with obvious vertical grooves and small punctate lenticels. The quality is hard, it is difficult to break, and the folded section is irregularly sliced. Blood vine pieces are oval, long oblong or irregular oblique slices, 3-10mm thick. The cut wood is reddish-brown or brown, with a large number of duct holes, irregularly arranged, with resinous secretions in the skin, reddish-brown to black-brown, and arranged in a 3-10 eccentric semicircle or circle with the wood. ring. Small marrow, biased to one side. Indifferent, obscure. More resinous secretions are preferred.
Microscopic identification
Stem cross section of stalks: rows of cork cells to dozens of rows, micro woody to woody, some brown. The plug contains 2 to 4 rows of cells with brown inclusions. The cortex is narrow, with more than 10 cells, containing yellowish-brown substances; numerous stone cells, scattered in groups, stratified veins and pores, filled with red-brown material, and a few calcium oxalate crystals surrounded by parenchyma cells. Containing calcium oxalate crystals, thickening of cell walls containing crystallized wood; a few secretory cells scattered. The vascular bundle is heterogeneous, with several eccentric rings arranged alternately between the phloem and xylem. The outermost phloem is a thick-walled tissue annulus composed of stone cells and fibers. The cells inside and outside the annulus sometimes contain calcium oxalate crystals; the phloem-secreting cell constants are more than 10 tangentially arranged in layers, containing yellow-brown, Red-brown or golden-yellow secretions; numerous fiber bundles, scattered, surrounded by cells containing calcium oxalate crystals to form crystal fibers; a small number of stone cells, scattered; ray wide l-4 column cells, curved, and more being squeezed. The formation of a clear layer. The xylem ducts are more than single or two scattered, with a diameter of about 400μm. Some internal walls are accompanied by brown lumps, mostly crescent-shaped; wood parenchyma cells are mostly around the catheter, and the walls are thicker and contain more brown substances. Cells; wood fibers also form crystalline fibers, several were arranged in layers; xylem ray cells pit obvious, and some containing brown matter. Small marrow, eccentric, most of the secretory cells of the medulla.
Powder characteristics: brown red.
1 There are many clusters of stone cells, which are rectangular, round, triangular or square, with a diameter of 10-80μm. Some cells contain red-brown pigments, and a few contain calcium oxalate prisms.
2 Fibrous bundles, pits and cells are not obvious, and the cell bundles around the fiber bundle contain calcium oxalate crystals to form crystalline sheath fibers.
3 There are numerous secretory cells containing reddish-brown resinous pigments arranged in strips or irregular blocks.
4 The tube fragments are mainly bordered pits.
5 The cork cells have a polygonal view of the surface of the cell and the walls have oblong holes.
6 thin wood cells pitted.

hydroponics system-nutrient technique (NFT)
NFT does not give average support to roots. Typically, the roots sit in a long sloping channel irrigation (Fig. 1.1). The nutrient is introduced into the high class of the canal and allowed to flow over the roots after which it drains into the nutrient tank. This is then re-pumped back into the channel to repeat the watering process.
This feed cycle can be intermittent or continuous. An & lsquo; The intermittent 'rss cycle is controlled by the clock and repeated several times per hour. this is sometimes called the "NFT pulse". The NFT pulse usually achieves better aeration of the roots as the roots are exposed to air between each feed. A & lsquo; continuous' rss cycle works non-stop. This is often used in commercial operations.
You can easily grow your favorite flowers at home without muddy mess and need to water your plants regularly.
Hydroponics is an ideal way to grow plants in urban areas. This makes it a great hobby that helps you to relax and it is fun to watch the hydroponic plants grow in the garden nft.
