(1) Identify the quality of Clivia from the leaves: Identify the quality of young varieties that have not yet blossomed: ① Look at the width. Leaf length-width ratio less than 4 is the top grade, 5-6 is the middle grade, and more than 7 is the general variety. Look at the pulse condition. The pulse is obviously raised in the shape of "sky" or "sun", reaching more than 1.5 mm, with large pulse distance, clear vision and obvious touch, which is the top grade. ③ Look at the thickness. The thickness of the leaves of the best varieties can reach more than 2 mm.4 See the brightness. Glossy is the top grade, but dull is the middle grade.
Variety identification method of mature Clivia: ① The leaves with a width greater than 10 cm are famous products, the ones with a width of 8-9 cm are top products, and the ones with a width of 6-7 cm are middle products. ② The leaves and the ratio of length to width are about 4∶ 1, 5 ~ 6 ∶ 1 are excellent products, and 7∶ 1 is medium products. (3) The top grade is the one with bright leaves and emerald mesophyll between transverse veins; The mesophyll is grass green, and the mesophyll is from China. ④ The veins of leaves are vertically convex, with obvious veins and large spacing, and the "Tian" grid is a famous brand; The transverse veins are obvious and the spacing is wide, but the left and right staggered irregularly is the top grade; The ones with obvious transverse veins but narrow spacing are middle products. ⑤ Top grade leaves are thicker (generally more than 2mm) and have leather-like appearance; Thin leaves are medium products. 6. The tip of the blade is round and blunt, slightly sharp, and the tip is buckled upwards for the top grade; The tip of the blade is pointed, and the tip of the blade is buckled downwards. ⑦ The leaves are tall and straight, extending at an angle of 45 above the syncline, and the upper and lower leaves are of equal length, and the fan shape is a famous product; The oblique angle is slightly larger, the blade length is similar, and the left and right arrangement is basically in a straight line for the top grade; The leaves are inclined and arched, and the leaves are of different lengths.
(2) Identify the varieties of Clivia from the flowers: the flowers with thick and round arrows are the top grade, and the flat and thin ones are the middle grade. The flowers are large and colorful, shaped like a wide funnel, and the petals are everted or spoon-shaped for the top grade. Generally scarlet, orange and apricot are the top colors. The flower shape is small, tubular, with upright petals. Pink orange blossom is a product of China.
