According to the medicinal part, we called the kind that use bark to process Chinese Medicinal Herbs Bark. Bark is the outermost layers of stems and roots of woody plants. Some of them have special medicinal value, through the historical experience and modern science, now they are important in herbal medicine area. Such as Magnoliae Officinalis Cortex and ALBIZIAE CORTEX.

Fruit Tree Summer Management Techniques
The summer management of fruit trees is an important part of the management of fruit trees in a year, and it has a great impact on the output of fruit trees that year. Therefore, the following technical points are proposed. First, fruit management 1. Use of hormones to preserve fruit. Shake 2/3 of the tree crown spray 10PPM "2.4-D" or 50PPM "900" + 0.5% urea + 0.2-0.3% "potassium dihydrogen phosphate" mixture of fruit, every 15 days and then spray once. Navel orange with "fruit most" 3 times fruit, or with 12PPM "E T-2" or "Green Settle" against umbilical yellow, can also be used "yellow ester" coated fruit top. 2. Thinning fruit bags. Shatian pomelo and Xia orange were used to thin fruit and set fruit in the middle and late June to remove fruit, deformed fruit, small fruit, and dense fruit. The amount of fruit left can be determined according to the ratio of leaf to fruit, 40 to 50 leaves of orange citrus fruit leave a fruit, and 100 to 150 leaves of Shatian grapefruit leave a fruit. In the basis of fruit thinning, spray once insecticide and fungicide: use "green crystal" 1000 times solution + 50% "carbendazim" 600-800 times solution or "big student M-45" 1000 times solution. After the liquid is dry, it is timely bagged. Second, the application of stable fruit fertilizer, strong fruit fertilizer 1. Steady fruit fertilizer. In the middle of May, fertilization of trees was observed. For trees with weak vigor and large amount of flowers, the adult pomelo trees of Shatian should be fertilized once with soil, and phosphorus and potassium should be used for fertilization to reduce physiological fruit drop. 2. Strong fruit fertilizer. In the first half of July (deciduous fruit trees in the middle of May and mid-May, Shatian pomelo in late June), the first strong fruit fertilizer was applied. In general, the results of each tree planted manure 40-60 kg, urea 0.3 kg, 0.5 kg of superphosphate, 2-3 kg of plant ash (or 0.5 kg of potassium sulfate), while irrigation 100-200 kg. After the beginning of autumn, apply a second strong fruit fertilizer to promote fruit enlargement. The fruit industry station recommended the use of "Kaifeng" fruit tree special compound fertilizer, a significant effect on improving fruit quality and yield. 3. Irrigation. After entering the flood season in July, every day, it is necessary to irrigate the water for 7 days, each time irrigating 100-200 kg/plant, in order to ensure the fruit's need for water expansion. Third, seize the key period, the prevention and control of pests and diseases 1. Orange red, yellow spider prevention and treatment: In the spring prevention and control, continue to do a good job of prevention and control of red and yellow spiders, on the basis of forecasting, do a good job of effective prevention and control, effective drugs There are: "Nisuolang", "fruit saint", "broom net", "Golden Fortune", "alien tyrants tyrants" and so on, the use of "green crystal" biological pesticides particularly good results. 2. Scale insects: scale insects are generally more serious, it is necessary to pay attention to observation and control, the best choice for the use of "fruit St." 800-1000 times liquid, spray once every 7-10 days, can also choose "green" biological pesticide. At the same time, it can also treat lice. 3. TianCai: From mid-May to early June, artificially capture Tianlong adults, and start killing Tianlong eggs and larvae in early June. 4. Rust wall lice: From June to September, the prevention and control of any copper rust in the leaves begins once every 10 days for 2-3 consecutive times. The agent can be used 65% "Dyson Zinc" 800 times solution or "Santa" 1000 times. 5. Leafminer: The leafminer mainly damages young shoots and occurs mostly in June-July. The combination of control and spraying shoots shoots. When the shoots grow to 2-3mm, they are immediately sprayed and prevented every 7 days. Continuous spraying 2-3 times, the main selection of pyrethroid pesticides, "green crystal" biological pesticides particularly good results. 6. Pear-hoofed tiger, pear big pear, small pear borer, pear net spring, pear black heart disease, etc.: 90% "trichlorfon" 800-1000 times liquid + 65% "fuzoite" (or "carbendazim") can be selected. ) 600 times liquid prevention. Fourth, do a good job in summer pruning fruit trees summer pruning fruit trees are divided into pre-flowering and post-flowering pruning, pruning before flowering to adjust the amount of pruning flowers mainly for the purpose of protecting the fruit, May-July summer pruning to improve lighting And for the purpose of promoting high-quality autumn shoots; Summer pruning from August to October to promote flower bud differentiation purposes. Sapling pruning is mainly plastic surgery. From May to July, the main tasks of orange summer pruning are as follows: 1. For summer shoots, the result tree should be completely wiped out, and the young tree should be picked in time. Wiping the summer shoots should not be too late. It is mainly to wipe summer shoots. Wangshu leaves 2-3 shoots for summer shoots. In 2.7 months, unreasonable large branches and branch shoots were cut off to improve ventilation and light transmission. At the same time, combined with the fruit-shearing branches and fruit-bearing branches of short-stemmed fruits, the quality of autumn shoots is promoted, which lays the foundation for the next year's high yield. 3. Summer is the best time to make young tree branches, cut roofs (open skylights) and plastic surgery for Shatian pomelo to improve the ventilation and lightness of the crown; at the same time, use hormones to promote flower preparation at the end of August. Fifth, other work 1. Orchard weeding. To prevent soil erosion, maintain soil fertility, promote weeding and no-tillage, preserve low weeds to improve the orchard's ecological environment, reduce soil temperature in summer, remove or entangle the tall weeds, and improve air and light conditions in orchards. 2. Do a good job in the "high-risk alternatives" of old and inferior fruit trees and the work of high-successive planting trees in addition to sprouting, twigs, and topping.
