1. Clever management: potted crab claw blue, should use loose, fertile and drainage smooth condensate acid culture soil, should not pan water, from spring to summer, every lo - 14 days 1 thin liquid fertilizer, summer Stop fertilizing in the high temperature period; from the beginning of autumn to flowering, fertilizer and water should be continued, generally applied once a week liquid fertilizer or compound fertilizer, before flowering increased 1 - 2 times available phosphate fertilizer. During this period, sufficient nourishment should be provided, which is conducive to the formation of flower buds and also to bright colors. The crab claws are half-shade. After spring, they are placed in a leeward sunny place. After summer, they are moved to cool, cool and shaded areas. In the summer season, the growth of crab guarana is in a stagnation stage. In this case, watering is less, but daily spurts are required. Water 2 - 3 times, if watering is too much at this time, easy to rot, after the fall, can be placed in more sunlight to stimulate flower bud differentiation. C. jasminoides are not tolerant to cold, and they should be moved into the room after the cool autumn season. They should be placed in a sunny place. The room temperature should be maintained at about 15 degrees Celsius. Buds should be sprayed regularly to keep the abnormal stems and buds moist. The flowering temperature is preferably 1o-15 degrees Celsius, and a short dormancy period appears after flowering. Watering should be stopped, fertilization should be stopped, all the spent flowers should be cut, and the plant shape must be trimmed until new shoots emerge on stem sections. After the normal water and fertilizer management.
2. Anti-dropping: The main cause of falling and budding
(1) In the late autumn and early winter, cold currents attacked. When the rootstock was frozen and stopped growing, most buds would fall off. The use of triangular arrows as the rootstock is more serious because the triangular arrow grows vigorously at temperatures of 25-37 degrees Celsius, grows slowly at around 20 degrees Celsius, and stops growing at about 15 degrees. Therefore, the arrow is grafted with a triangular arrow. Crab blue, must pay attention to cold.
(2) In the flowering period, the potted soil is too dry, sudden changes in temperature or excessive temperature difference between day and night, and low temperature below 0 degrees Celsius are all liable to cause falling and budding.
(3) Flowerpots are moved randomly at flowering time, which can also cause broken stems to cause falling flowers and falling buds. In the early stages of bud formation, watering too much can cause buds to fall off. For the above situation, take insulation measures, moderate watering, do not move, you can effectively prevent falling buds.
3. Anti-yellowing: Crab vine is a short-day flower, afraid of strong light exposure, hi slightly acidic soil, high temperature, direct light, air drying, poor ventilation, and basin alkaline, etc., can cause stem sections of Crab C Yellow, and easy to fall off from the base. If C. jasminoides suffers from spider mites, it will also cause the stem sections to become yellow and fall off. Therefore, in the summer, care should be taken to cover the shade, spray the water on the plants, and pay attention to the maintenance of the ventilated area. When the spider mite is found to be infested, spray 1,000 to 1,500 times the omethoate solution immediately.
