I. Introduction of Huaye Collaboration Trachelospermumjasminoides Flame is a horticultural cultivar of the Apocynaceae family (Trachelospermumjasminoides (Lindl.) Lem.). Evergreen woody vines, stems with inconspicuous lenticels. Branchlets, leaves below and young petiole pubescent, slightly old branches and leaves glabrous. Leaf leathery, elliptic to ovate-elliptic or broadly obovate, 2–6 cm long, 1–3 cm wide. The old leaves are green or light green, the first round of new leaves is pink, the majority of each branch is a pair, a small number of 2 to 3 pairs of pink leaves, the second to third pair of pure white leaves, in pure white leaves and old green leaves There are several pairs of white leaves, most of the veins are white, irregular white patches on the leaves, and the white components from the new leaves to the old leaves are gradually reduced. Jatropha is widely used in Japan for landscaping, park landscapes, garden greening, and indoor tabletops. Because of its colorful colors and widely enjoyed by consumers. Second, the rapid propagation of mosaic plants in miniature mosaic pots Jacaranda is a plant that is relatively easy to take root. During the process of industrialized nursery production, through the exploration of the technology of propagation of the karyotes, bold technical innovations were made from the perspective of commercial production, and a set of them was summarized. "Multi-branched and rapid-growing seedling production technology." In short, several cuttings (5-8 roots) are directly inserted into the container of the commodity size and size, and after rooting, further fertilizer and water management and proper pruning are performed to cultivate plant-type plump and leafy colors, meeting the requirements of quality standards. commodity. The shortening of the curing time, the reduction in the number of pruning, and the saving of the pot changing step substantially shorten the production cycle. We will now explain in detail the practice of using this technology for seedling production. 1. Cutting seedlings The use of advanced plant nursery technology for production, which is characterized by easy management, high unit yield, good seedling quality, nursery time is about 3 to 4 weeks; 1) Facilities conditions. There are 1 to 2 shade nets shaded and have a spray condition and a well-drained greenhouse. The width of the elevated seedbed is between 140 and 170cm. Five or six plug trays can be placed across the pendulum and the aisle is 50cm wide. 2) Media mixing and loading trays. Media: 60% peat + 30% perlite + 10% vermiculite + 2.5kg/cubic APEX14-14-14 long-term controlled-release fertilizer, imported imported Fifard peat, uniformly mixed media, and disinfected with 600 times liquid of enemy pine. Add lime to adjust the pH value to between 5.5 and 6.5, then place the medium into a 6cm pot and place the pot in a 54cm28cm 5.7cm dish. After loading, the nursery pots are placed neatly on the seedbed and the pots are poured before pouring. permeable. The seedbed is disinfected with disinfectant before it is placed. 3) Clipping and cutting of branches. It is very important to select the parent stone of the huayeluo network. Select the strong mother-family disease-free pests to cut the cuttings, cut them into 2~3cm long, one pair of leaves, and leave 1.5~2cm under the leaf base. 0.5~1cm. Each pot inserted about 5 cuttings, without hormone treatment, cutting depth to the substrate close to the surface of the media as well. The entire operation keeps the branches relatively moist and avoid losing water. 4) Maintenance management. Mosaics often take 2 weeks to form roots. Intermittent spray leaves are used before rooting to ensure that cuttings do not lose water. It is best to have an automatic spray system. The relative management will be relatively simple. It should be noted that the cutting medium of the mosaic is Can not accumulate water or it will affect the survival rate after rooting and rooting. After a period of rooting, the medium should have a process of alternating wet and dry, which is very beneficial to the growth of the root system. Spray the protective fungicide (1000 mg of mancozeb) and insecticide (1500 times of Lethbout) once every 7 days, and mix the appropriate liquid fertilizer (APEX20-10-20 2000 times) in the liquid. Or spray 14-0-14 fertilizer 1500 times). 2. The management point of growth period 1) Water Management: Treated with tap water or disinfection, acidity adjustment, etc. This is closely related to the control of the internode length of the corrugated travertine. As a miniature pot, it requires a short and compact internode. 2) Fertilizer management: Long-acting controlled-release fertilizers have been mixed in the medium, so the seedlings can be absorbed into the fertilizer once they are rooted, and the fertilizer supply is continuous and stable throughout the growing season. So less fertilizer in the later period. Top dressing is mainly based on liquid fertilizer, which can be applied with 20-10-20 water-soluble fertilizer 1000 times liquid. The frequency of topdressing is usually 10 to 15 days. Conditionally, the EC value of the medium can be measured. If it is less than 1.0, it can be top-dressed. 3) Pruning work: vine plants, controlled by pruning cane length, can promote branching, which is conducive to full plant type. When pruning for the first time, when the length of the cane reaches 8cm, leave it at about 6cm, and then trim every 4~5cm. Usually, pruning can be done 2 or 3 times to have a good pot shape. 4) Control the reasonable placement density: After the plants grow to touch each other, they must be timely and sparsely placed, which is conducive to the full growth of the plants and avoid rotten branches and rotten leaves. If not dilute in time, the plant type of each pot is difficult to ensure fullness, and new leaves may be rotted and old leaves may fall off, especially in high humidity and hot season, and such problems are more likely to occur. 5) Illumination control: Before the sale of flamingo stones, 75% of the shade net (light intensity is about 8000~15000Lux) shall be covered before sunny days. The leaves will be mainly green, but the growth will be faster and grow stronger. In the month before the sale, the shade net was removed or the degree of shading was reduced (in summer). In the case of relatively abundant sunlight, the new leaves that grew up were colorful and dazzling. 6) Prevention and control of diseases and pests: Diseases mainly include anthracnose and leaf spot disease. They are treated with 50% thiophanate-methyl 600-800 times solution or 70% mancozeb WP 800-1000 times solution. Pest control: A, red spider mites, moth larvae and other larvae with a 1000 to 1500 times the prevention and cure; B, aphid hazards, with imidacloprid 25% wettable powder 1500 times or 48%. Emulsion 2000~3000 times liquid prevention and treatment; C, moth larvae hazards occur mainly from 6 to September to pay special attention, adult trapping and killing before spawning, when the larvae hazard timely chemical control, 1% avermectin EC 2000 Times or 5% beta-cypermethrin EC 1000-2000 times spray, spraying should be carried out in the evening; D, nematode treatment can be used 40% Ke-P EC 2000 times liquid irrigation medium. It is necessary to take precautions as the mainstay and to rule as the supplement, and to rule in a timely manner. Maintaining the ventilation of the environment can reduce the risk of pests and diseases. Third, the other treatment before the sale a) Domestic Sales Prior to the sale of the miniature potted plant, the bonsai chestnuts are often changed again as needed. A variety of small porcelain basins with sizes ranging from 6 to 8 cm are used. When the basin is changed, appropriate amount of slow-release fertilizer is added and the dead leaves and moss that affect the ornamental are removed. It can also be sold with other plants and pots, or used as a material for a large group of pots, as well as flower-shaped materials. b) Export commodities For export, the quarantine of media and pests is very strict. The medium should not have mud or nematodes, and the plants should not have any pest or disease of any quarantine objects. Therefore, in the beginning of production and the entire process, all must be closely linked. Usually nematocide is added to the culture medium, and the medium must be mixed in a clean place. The container must be fresh and uncontaminated. An effective disinfection must be performed before the product is ready to be exported. The moss and the moss are clean and packed with special flower racks. Only in this way can we export through customs.

Altitude: high altitude area light, clean air, environment close to original condition, no industrial pollution. With an average elevation of 1160-2900m, the central health center has a strong uv light, which produces the natural pollution-free apple, which conforms to the concept of a modern green diet.
Temperature: moderate temperature can avoid the chance of fruit tree encountering disease. The average temperature in ningxia is 8.4 degrees Celsius, which has an important influence on the growth, development, yield and quality of apple. The piedmont apple is thriving in such a good environment.
Humidity environment: moderate amount of rainfall provides necessary conditions for apple's growth. The annual rainfall in the central health region is 186 millimeters. The fruit is slow to grow and the fruit is hard and hard, which fully guarantees the fruit's sugar content and the relatively average size of apples.
Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
