First, the biological characteristics of Astragalus jaundice, scientific name Gassiu Surattensis Burmf. Commonly known as American oak or yellow peony, is hematoxylin, genus of cassia, deciduous trees for winter, leaflets 3-10cm long, 1.5-4cm wide, apex obtuse (or blunt and small pointed), leaflets more than 5 pairs, Short round or elliptical; flowers bright yellow (also known as yellow flower pods), inflorescence length 8-12cm, and no significant beautiful sepals, 5-10 stamens developed, fruit for capsule, no obvious nodes, petiole and The axis has glands. Second, the purpose of the test Astragalus, summer and fall of the second quarter flowering, flowering longer, about 3-4 months, the flower is bright yellow, dazzling color, Yan but not Jiao, often plant, campus or urban road greening species of trees. It is understood that so far people have not introduced it as a potted flower into millions of households. If the potted plants are successful, it is not only a good variety of potted plants, but also a new variety of potted plants. III. Test methods and procedures (1) Method: The horticultural research group of Shantou Shishi Scenic Area conducted a trial of cutting pots and cuttings with potted plants and obtained the survival and pot flowering of the year; on this basis, the cultivars of yellow flowers were also cut. The test proved that the root of the Astragalus root was used as a cutting, and its survival rate and effect were better than that of the shoot as a cutting. (B) Step 1, cut potted plants in the early spring, before the Astragalus not pumping leaf buds (generally in February or so), the trunk of the Astragalus plant was truncated, leaving about 20cm Astragalus pile head transplanting basin, Put it in a cool place. After about one month, shoot buds and leaves. At this time, you can apply a thin compound fertilizer once. Then move it to a place with strong sunlight and allow it to grow normally. During the growth period from May to July each year, observe the growth trend of the scutellaria baicalensis, the length of the shoots, carry out the necessary pruning, carry out reasonable fertilization, and suppress the long branches and promote the germination of the lateral branches. The pruning was stopped from August to September, and the fertilizer and water were appropriately controlled to control the vegetative growth of Astragalus, so that the vegetative growth turned to reproductive growth, which promoted the differentiation, formation and development of flower buds. If some of the branches are too long at this time, bending, climbing, and shaping may be performed in the afternoon when the moisture content of the shoots is small. In early October, the potted astragalus began to flower. 2. The potted plants are planted in late winter and early spring. Before the buds of the yellow saplings are sprouted, the branches of the scutellaria baicalensis are cut into sections about 20 cm long for cutting. After cutting, care should be taken to shade and keep the soil moist. About 2 months later, the branches of the cuttings of A. persicae have taken root, and they can be gradually put on pots. Put them in a cool place for 1-2 weeks after putting on pots, and then gradually move to sunny places, and then insert the pots. The management of Astragalus is the same as the method of cutting potted plants. Because of the slower growth of potted astragalus than that of a potted plant, the flowering period was delayed by one month compared to the cut potted plant, that is, flowering did not begin until early November. In the potting process of Astragalus membranaceus, after more than one year of careful observation, we found that the roots of the residual underground part of Astragalus after replanting can regenerate into a new plant. According to this characteristic of Astragalus, we have a The cutting experiment was carried out and the results all survived. The experiment proved that the roots of Astragalus roots were used as cuttings, and their survival rate and growth rate were both higher and faster than those of cuttings. 3, Astragalus root plug method in late winter or early spring, cut thick roots of Astragalus about 15cm segment cuttings, without shading, keep the soil moist, about 1 month after the root can survive and can be on the basin. The survival rate is as high as 90%. Astragalus root insertion method not only makes full use of and enhances cutting propagation materials, but also creates yellow bonsai bonsai according to different forms of roots of Astragalus membranaceus, which greatly enhances the ornamental value of potted plants of Astragalus membranaceus. Potted astragalus, began to bloom in October, flowering period of about 2 months, winter leaves after the change of soil, pruning, the following year 5-6 months began to flower, flowering period of about 1 month. Fourth, the management of astragalus potted plants 1, timely cutting and cutting off the pot, in the late spring and early spring, Scutellaria pruning buds before germination, cutting branches or root cuttings and cut off the pot, because at this time the Astragalus is accumulated nutrients And semi-dormant state, this is the key to success and improve survival rate. 2, pay attention to shading and regular watering. Particular attention should be paid to strengthening the management after the first budding to prevent dehydration from shrinking, and to realize that the second long sprout is truly alive. 3, after the basin of jaundice should be placed in a cool place, about 10 days and then gradually moved to sunny places for normal management. 4, reasonable pruning, control branches too long, to promote collateral germination. When the branches of Scutellaria baicalensis grow to about 20cm, pruning should be carried out. The general number of times is 1-2 times, combined with climbing and shaping to achieve a complete and beautiful crown. 5, a reasonable fertilization. Potted jaundice, should be placed in the sunny place after the upper basin should be applied thin fertilizer to germinate the buds, during the subsequent growth, the compound fertilizer applied twice a month, when you can trim another thin fertilizer once, this Fertilizers in the stage should be dominated by N and K fertilizers. By the middle of July and August in July, fertilization should be dominated by P fertilizers, while N and K fertilizers should be applied less or not. 6, timely control of fertilizer and water. The seedlings were planted in August-September, and the shoots grew slowly, which was conducive to the storage of nutrients and flower bud differentiation. Too long shoots could not be trimmed, and bending and climbing were applied. V. Test results 1. The survival rate of the potted plants of Huangqi was 100%. 2. The survival rate of shoot cuttings reached 58.7%. 3, root bar cutting up to 90%. 4, the pot cultivation in the year when the flowering and scab. VI. Conclusion 1. All of the above methods can survive, but the survival rate of potted plants and potted plants is higher. The technical operation of the three methods requires less, the breeding speed is faster, and the cutting propagation number is also more. 2, cut off the basin and cuttings should be timely, this is the key to survival. 3, the success of cutting potted plants can make Huangqi early 3 years of flowering, greatly improving the production rate of Huanghua potted plants. 4. The root cutting method can not only fully utilize the root, but also form a rooting bonsai. 5, Astragalus pots success, its high ornamental value, long flowering period, so that potted flowers have added new varieties, but also can enter thousands of households, become a public flower, to beautify the hotel, home and make contributions.
