The single chrysanthemum, also known as variety chrysanthemum, has one plant per pot, one plant and one flower, and is generous in shape and appearance, and can fully express the characteristics of the variety. After many years of practice by the author, I summed up the technical points for the cultivation of Dui Juju: namely, the winter, Tibetan, spring, summer and autumn. 1. The selection of foot bud cuttings in winter and autumn and late autumn and early winter will be carried out in sunny indoor and low temperature (around 3C). If the soil is not dry, it will not be watered to prevent leggy. 2. In spring, the second year of winter, the foot bud seedlings of the Dongzang are planted in pots filled with ordinary culture soil, placed in outdoor leewards, maintained at the sunny place, and properly watered and pay attention to loose soil to promote rapid root growth. 3. Sha Ding When the seedlings grow to about 40cm, with the method of phased batching to promote the germination of new foot buds. After mid-July, picking up and wiping buds, until the sprouting of several foot sprouts in the basin soil, choose to leave a pot from the edge of the pot full of sprouting foot sprouts, and the rest of the whole. Dig out. When the seedlings to be left grow to a height of about 15cm, they shall be planted in a "billet basin" containing rotted leaf soil. The old culms must not be cut off until the new seedling grows to a height of 40cm (at this time the new root system). Has been enriched), then cut the old stalk Qi. In order to form the three roots of the old, middle and blue shading seedlings, it is necessary to fill the soil three times in succession with the growth of the new plant, and add fertilizers such as broken bone pieces, rotted leaf soil and superphosphate. 4. After autumn and mid-August, after the new strain of Shading is formed, loosen the topsoil and fill it with 3 layers of fertilized soil. Planting in mid-September, the flower buds have all been formed and entered the bud stage. They should be tied in time with fine bamboo baskets and tied with green plastic tape every 15cm or so. After the beginning of September, the thin-kneading water can be applied once a week, and potassium dihydrogen phosphate 500-fold or potassium phosphate-dihydrogen phosphate 1000-fold can be used for extra-root dressing, until the flower buds pass through. From autumn to early October, attention should be paid to removing all buds sprouting at any time with a knife to ensure full development of the top bud. The starting and ending time of the four cultivation sessions of Duo Duju vary with different conditions such as climate and environment. Readers and friends should be flexible in the cultivation of the natural conditions. China Agricultural Network Editor
