Red rim is an umbrella tree with leaves. It's dark red, it's red. Leaves to life, elliptical. Quest, chute, chute. May-june. Maturity or blue white, august-october. Seeding, adhesion and barbing can be used to reproduce。
Red-end wood leaves are red, little fruit is white, and dried leaves are like corals. They are rare truncheons and good cutting material. The impact of this is felt in gardens where many grasses are planted or planted between them and the usual green wood。
The rhesus wood belongs to the falling bush and is about 3 metres tall. A red hairless, often powdered, marrow wide, white. Single leaf, live, eggs to elliptical form, 4-9 cm long, 4. 5-6. 5 cm wide, side veins 5-6; leaves bearing 1-2 cm long. The two sexes form the umbrella house, and they are the ones who live. Small flowers, yellow and white. Flower jar, tooth triangle. The petal tongue. Maurice four. Flour mat。
The sub-room is close to the fall of the egg, and the hair is short. Nucleus fruit, osteoporosis, crumbs; white or slightly purple when ripe. Leave the bush. Dark red, blood red. Leaves to life, elliptical. Quest, chute, chute. Period may-june. Fruity milk or blue white, maturity august-october。
Cultivation: born in mixed wood or needle leaves at altitudes of 600-1700 m (up to 2,700 m in gansu). Extremely cold, drought-resistant, dry-resistant, trimmed, radiant, deep, wet but fertile soils. Red rim likes a wet and warm environment。
The appropriate growth temperature is 22-30 degrees celsius, with sufficient light. Red rim is fertilized, growing fast in a well-drained and well-fed environment. In summer, attention is paid to drainage, and winter is prone to freezing in parts of the north. It is cold-resistant, wet, semi-vaginal and fertile soil, and it is resilient and adaptable。
Rhesus tree farming techniques: rhesus wood is a falling bush of a mountain twilight collet, red autumn leaves, white little fruit, dry branches of leaves falling down, red as corals, a very precious viewing leaf, a mantle. Thus, greening the city as a tree-watching species is promising。
It's a long-term twig, usually 60-90 d, with a maximum survival rate of 80%. Long roots make management more difficult. According to our production practice in the greenhouses, the hard-wielding of rhesus wood is based on the following technical points, which not only increase the rate of seedling but also significantly reduce the length of rooting。
Preparation of means of production
Royal configuration: the nutrientable soil needed to bear the seedlings in the containers must be of good water conservation, permeability and light quality to facilitate movement. Rheimu has been rooting for a long time and has more chance of contracting the disease in the slots, so the emperor must be well ventilated. The selection of the grass-grass earth pearl rock = 2⁄3 is sufficiently mixed to ensure that the oxygen required for rooting is injected, mixed with the spraying of 0. 3 per cent potassium permanganate solution and completely disinfected by the emperor. It's better to put it in two days。
Selection of packagings: the selection of packagings is based on the type of tree, rapidity, root system growth characteristics and breeding time. The principle is to be suitable for the growth of the trees, without taking too much land. The selection of 7 cm x 11 cm is more appropriate, depending on the faster growth of the rhesus mollusc period and the time of breeding in the greenhouse。
The royal filling: in order to ensure that the trees grow well, when filling the soil into the container, it is necessary to relax, to refrain from airbags and not to be too tight, otherwise the lack of air in the container affects the roots of the tree to breathe. Put the soil-filled nutrient worms on the nursery bed and then spray the water. The surface of the soil will be reduced when the water is seep, with a level below 0. 5 to 1 cm。
Preparation of plant materials
Plug-in collection: generally available after the fall of the leaves in late autumn and early winter until the spring of the following year before the bud starts. Rhesus wood is inserted in the spring, making production easier. In early march, before the sprouts on the branches swelled, they chose to grow a strong, disease-free year. At that point, the fluids had just begun to flow, and the adhesion was easy to live。
Interception: rhesus wood is the root of the skin, 8-10 cm long and 0. 5-1. 0 cm long. The shortest is not less than 6 cm, and the smallest is not less than 0. 4 cm. It's best to make sure there are two to three full and full buds. Upper cuts range from 10 to 1. 5 cm and lower cut ranges range from 3 to 5 mm. The cutting requires a smooth cut to prevent the fragmentation of the skin and wood, so as to avoid the rooting of water decay. In addition, it is necessary to protect the sprouts at the upper end of the slot from damage。
Plugging: in order to promote rooting and increase the reproductive effectiveness of the piping, some treatment of the piping is required before the piping. Cut. After the good plugs are tied, two to three d in the water, preferably in the water stream, and if you use the container, you'd better change the water once a day。
If so, it would be preferable to use a certain concentration of root agents for the treatment of ear plugs. The piping of erythro-wood hardwood is based on the application of the 500x10-6 abt1 root powder solution and the quick-treatment plugs are more effective, with a root rate of over 90%。
Plugging methods: inserting an ear into the centre of the emperor, whichever is above the depth of the plume. Do not fall in, do it after, do it to the emperor, keep the ear close to the king, and do it strictly against the air. A perforation of water immediately following the plug will satisfy the water requirements of the slot and will bring the plug down。
Day-to-day management after insertion
(b) watering: periodic water spraying, which ensures that the incision is wet, subject to the control of the amount of the spray, which is appropriate in the light of the humidity of the emperor; the leaves shall be spread to ensure that the leaves are wet and that the emperor is not too wet. If the humidity is too high, it leads to low temperature, low oxygen content, effects rooting, and is prone to decay
His majesty's work also has its roots. It is appropriate to have 30 to 50 per cent of the water content of the former king. Spraying: the long-term rooting time of the rhesus mussels and the greater risk of infection with the fungs necessitate regular spraying. The microbicide is sprayed every half month after the incubation。
Fat pursuit: the green leaves start coming out of red rheumatism around 10d. When leaves are released, they should be followed up in a timely manner to supplement nutrients and promote root causes. We began to apply 0. 125% of the acid-corric acid complex spray solution at intervals of 8-10 d and liquid spray after 15:00 p. M.
After 20 d, roots began to take place, with an adjustment of 0. 17% on the basis of the growth of the root system and 0. 2% on the basis of the large formation of the root. (c) care: water-watering and day-to-day management taps are always prepared and weeds are always removed。
Greenhouse environment control: prior to rooting, the temperature in the greenhouse was 15 - 25°c, the temperature in the emperor was 15 - 20°c and the temperature in the atmosphere was too different from the temperature in the emperor. Temperature indoor humidity requires 80 to 90 per cent, and timely and effective measures to increase humidity are required for less than 75 per cent。
A proper shade is provided, light intensity is contained around 5,000 luxs and periodic ventilation. After rooting, water sprays began to be controlled, air moisture gradually reduced, light intensity increased, ventilation increased and tree resistance increased。
Synopsis: in this way, red rims are inserted in greenhouses, leaves begin to be laid around 10d, roots fully in about a month, and roots are above 90%. The hard branches inserted on 18 march were cultivated in greenhouses for two months, with an average height of up to 14 cm。
The seedlings of the rhesus wood, which are grown by this method, can be transferred to daejeon after a seedling of about 10d. Owing to container seedlings, scavengers are grown, with short periods and a survival rate of over 90 per cent. ♪ the big east nursery in beijing ♪
