The orchid falls on the shoulder

The shoulder drop standard of the lotus valve is different from that of the plum version. The lotus valve does not fall if the top of the two sidelobe is in a straight line, while the plum valve does not fall if the midline of the two side valves is in a straight line.

Shoulder fall is caused by insufficient pulling rod, Yin temperature and dampness can solve the problem. no, no, no. Water has a great influence on the length of petals and the speed of blooming. In some cases, it is the lack of strength caused by turning the basin. Do not move the position and direction of the flowerpot during the flowering period, which is conducive to the arrangement of the bell, turning the stem and the direction of the flower. Wet environment, dry but not dry material basin soil, the use of light flowers will be better.

The falling shoulder of the side petal of orchid will affect the perception of the whole product, which is not only related to the variety, but also related to the seedling condition and the management of florescence. Weak grass, lack of strength, water will lead to shoulder fall. The direction of light will also affect the opening direction of the flower and then the position of the sidelobe, and the oblique flower will bow its head. The blocking of the leaves during flowering will cause the opening of the side lobe to be blocked, often with oblique shoulder and shoulder opening. Temperature, humidity and over-drying will affect the opening speed of rods and flowers, and it is easy to produce good products when the temperature is stable and humid.

Among the three outer petals of the orchid, the middle one is called the middle calyx, also known as the main valve, and one on each side is called the lateral calyx, also known as the sidelobe. The so-called "shoulder", that is, specifically refers to the shape of the side lobe; the first kind, both sides of the side lobe slightly upward, that is, both sides of the side lobe angle of more than 180 degrees, called "flying shoulder", is a good product. Second, the side lobe is horizontal, that is, the parallel side lobe is called "one word shoulder" or "flat shoulder", which belongs to the top grade; the third kind, the side lobe droops slightly, that is, if the angle of the side lobe is less than 180 degrees, it is called "shoulder drop". This form is inferior. Fourth, both sides of the sidelobe droop greatly, and the main lobe to form a triangle, known as "falling shoulder", "tripod horse", "eight-character frame", in this form of flowers, is inferior. The lower angle formed by the main veins of the two lateral sepals (shoulder calyx and accessory lobe) of the orchid flower is less than 180 °, showing a slightly lower vertical shape until the bilateral calyx is close to merging into one, collectively referred to as "falling shoulder". Generally speaking, the lower angle of bilateral calyx less than 180 °~ 160 °is called "slightly falling shoulder"; 160 °~ 120 °is "small falling shoulder"; and less than 120 °is the big falling shoulder, which is inferior.
