The flowers are large, colorful, short, and full, which is a symbol of the success of Qiu Ju. How to make plants dwarf is a more complicated technical problem in cultivation management. After many years of exploration and practice, summed up ten methods of autumn chrysanthemum dwarfing, for flower lovers. (1) Cuttage of late-flowering chrysanthemums usually uses cutting methods, and sooner or later, it is one of the keys to the dwarfing of chrysanthemum. In order to make the plant taller than the feet, Trigeminal Dendrobium should be cut in June, and the single beetle should be cut in July-August. Compared with spring cuttings, the plants should be 10-20 cm shorter. (2) Cuttings should be short. In the past, stalks generally had 3-4 nodes and 10 cm in length. If the cuttings are changed to two sections, one section will be rooted and one part will be exposed. This will not only ensure the survival of the cuttings, but also shorten the cuttings. If single bud cuttings are used, as long as they are carefully maintained, the roots can be rooted under the festival and germination can be performed at the festival, and the dwarfing effect is better. (3) Planting should be done when the seedlings are above the pots. The roots should be planted on the bottom of the pots. The culture soil should be filled with 1/3 or 1/2 before. After the plant grows, the soil is gradually added. This is more than planted in the upper part of the pot, to hide 8-10 cm, and the roots of the stem into the roots, plant growth more prosperous. (4) Picking up the heart means picking up the growth point or tip of the plant, both inhibiting its growth and promoting lateral buds. Take-up time is generally about 10 cm from the height of the seedlings, and it will end at 3-5 days before and after the beginning of autumn. The number of picking up should be determined according to the growth habits of different varieties and cultivation needs. Some 1-2 times, some 3-4 times, or even more. It is worth noting that the time for the last picking should not be too late, otherwise there may be some buds and some buds cannot be opened. (5) Acupuncture can destroy some of the transducing tissue due to acupuncture, and the growth point of the plant is inhibited. Therefore, the purpose of dwarfing can be achieved. The specific method is to pierce the stem with a sterilized sewing needle or pin at the bottom of the growing point of the blade. Its depth, the general trend of penetration into the center, strong growth can be pierced. Through acupuncture, not only its height can be restricted, but also the stems can be thickened and the leaves can be enlarged and thickened. (6) The juveniles with potted stems in the spring, which have not been restrained, have grown tall in the autumn and are dwarfed by the general method. The salvage measure is to remove a part of the potted earth, and after deducting the water to make the stems soft, place the stems along the sides of the pots in the pots, and expose the top tip of about 10 cm in the center of the pots, and then fill the pots to the pots. along. After this treatment, the plants are not high until flowering. (7) In the stage of water-saving nursery, under the premise of ensuring the survival of the seedlings, watering should be minimized so as to promote root and seedlings. Until the plants enter the growing season and the vigorous growth period, in order to prevent plant growth, watering time should be around 10:00 am, the amount of water to maintain the degree of consumption on the day. Although some plants will suffer wilting in the afternoon, they will still be alive with dew and tide at night. (8) Control the fattening seedlings Due to the soil nutrients throughout the seedling stage, no fertilization is required, otherwise the growth will be rapid and the height will be difficult to control. After entering the vegetative growth period, the frequency of fertilization should be increased from small to large, and the concentration must be from small to large to meet the normal growth needs. Avoid excessive fertilizer and too much concentration, resulting in damage. The plant should stop spraying liquid fertilizer after budding, and use potassium dihydrogen phosphate for foliar spray fertilizer. (9) Rain protection This is an important aspect that people easily overlook. Artificial watering is easier to control, but the rainy season, especially the rainy days of a few days, will not only cause the plants to grow mad, the loss of soil nutrients, but also cause leaves yellow off, bare legs exposed legs, reducing the ornamental value. If there are a large number of rain control measures and the number of temporary shelters is small, they can be moved to places where the rain can not reach, and the flower pots can also be placed on the side. Rainstorms are too late to shelter from the rain. After the rain, the water in the basin can be poured out. (10) hormones used for the dwarfing of chrysanthemum, chlormequat and b9. Chlorothorax watered the soil with 1000-3000 times liquid, and poured it 10-15 days after the upper pot, 10 cm pot diameter, 100 ml each time. The watering effect was best when basin soil needed watering. B9 Spray the leaves with 1000 times liquid and do not water it for 24 hours after spraying to facilitate plant absorption. The amount of family support is small, the b9 solution with higher concentration can be used, and the stem and growing point can be painted with a brush and the effect is also good. The time of using hormones generally starts from cultivation, and the plants begin to bud. China Agricultural Network Editor
