The breeding methods of trigonometry include seeding, interpolation, etc。
Seeding: seeds collected in the year, infested with pest-free seeds are selected for planting for 15 minutes, then impregnated with hot water, followed by 12-24 hours of sprouts with hot water, until the seeds inflate, and are placed on the surface of the matrix, then sprayed with soil, and then do warming, shifting, etc。
Plug-in: prepare a base for disinfection, then cut last year's coarse branch with leaves and insert it into the matrix。
I. Methodological methodology of translamm
Seeding
(1) selection
Seeds are selected first before seed is planted, and successful seed selection is directly linked to success。
2 is the seed selected for the year. The longer the seeds are saved, the lower the gestation rate。
3 seeds are selected to be full of seed grains, with no disability or deformity。
Seeds without pests are selected。
(2) leaching
1 includes two concepts, one for seeding and the other for seeding. Households often plant hot water about 60°c for seeds for 15 minutes, followed by hot water for 12-24 hours。
2 put the seeding matrix in the pot to make it hot, and any bug can burn to death。
(3) dynamite
The seeds are immersed for 12-24 hours with warm water (like temperature and wash water) until they suck and swell. For seeds that are very common and easily fertilized, this work can be avoided。
(4) seeding
1 for small seeds that are difficult to trap with hands or other tools, one end of the water for toothpicks can be wet, a piece of the seed can be glued to the surface of the matrix, covering 1 cm thick, and the seeding basin can then be placed in water at depths of 1/2-2/3 at the height of the flower basin, with the water slowly leached (known as “basket leaching”)
For larger seed varieties that can be caught with hand or other tools, the seeds are placed directly into the matrix at a distance of 3 x 5 cm. After broadcast, cover the matrix with a thickness of 2-3 times the size of the seed. The seeding matrix can then be wet with sprayers and pyrotechnic flowers, and then water when the pelvis is dry, so that the water is not so intense as to prevent the seeds from being washed up
(5) management after seeding
After planting in late autumn, early spring or winter, when cold tides are low, the flower basins can be wrapped in plastic film to protect the temperature from humidity。
Once the seedlings are out of the ground, the film is lifted in time and the seedlings are given light from the sun before 9. 30 a. M. Or after 3. 30 p. M., otherwise they will grow softly。
Once most seeds have come out, appropriate seedlings are needed: sick and unhealthy seedlings are removed, leaving some space for each other to leave behind。
When most of the seedlings grow three or more leaves, they can move。
2. Plug-in
(1) it is common at the beginning of spring and autumn to use the branches born in the current year, or at the beginning of spring to use the branches born last year。
(2) plugin:
One is material such as trophic soil or river sand, mud and carbon, which is used to plow。
2 family incubation is restricted to very difficult conditions to obtain an ideal piping matrix, which is recommended for use and which has been formulated and disinfected。
Coarse river sand can also be used, but several times before it is used. Sea sands and river sands in saline areas are not used and are not suitable for flower plants。
(3) the choice of branches:
1 when a small branch is inserted, when the plant grows and thrives between the end of spring and the early autumn, it is chosen to use the thick branch of the year as an embroidery。
After cutting the branches, select a strong section, which is 5-15 centimetres long, each with more than three leaves。
3 when cutting the plugs, it is important to note that the above clippings are roughly 1 cm flat above the previous leaf, the lower cut is approximately 0. 5 cm tilt below the lower leaf, and the upper and lower clippings are flat (the blade is sharp)。
In the case of hard-wire plugs, the last year's strong branch was selected as an ember after the early spring temperature had recovered. Each of the slots is generally kept in 3-4 sections, which are cut in the same way as the small branches。
Ii. What's a triangle
1. Species discussion
Triangular mammoths are generally triangulations, not to mention vegetative trees, maples, chicken maples, etc., which are biologically part of the vegetative community, vegetative doors, double-leaved vegetative phytoformes, boreals, typhus trees, which are widely distributed in china, china, south-west china and south china, and which have a high value for viewing. They can be planted alone, bushed into shrouds, or used as walking trees, shore trees, or pellets。
2. Form characteristics
(1) triangular maple is leafed wood, which is 5-10 metres high; tan or dark brown, which is rough; and thin, which is either purple or purple green, and gray or gray over the years。
(2) leaf paper, elliptical or re-egged, with a base near the circle or wedge, usually three shallow cracks, with the cracks stretching forward; flowers are mostly the result of short, soft-haired umbrella room platters, yellow-coloured, yellow-coloured petals; fins, yellow-coloured, particularly small nuts; and flowers, four months, fruit, august。
3. Scope of distribution
Triangular beams are widely distributed in china, china, south-west china, south-south china, shandong, henan, jiangsu, zhejiang, anhui, jiangxi, hubei, hunan, guizhou, guangdong, taiwan, and so on. They are found in broad leaf forests 300 to 1,000 metres above sea level。
4. Growth
(i) temperature: triangular maple is warm, cold-resistant, with the highest growth temperature of 15-25°c and is resistant to temperatures of 10-20°c below zero。
(2) humidity: triangular maple is damp, slightly drought-resistant, more humid, and can grow normally from 800 to 1,300 mm of annual rainfall。
(3) soils: triangular maple is fertile and less demanding and is found in fertile, lax and well drained soils。
(4) lights: triangular maple suns, slightly obscenity, larvae fear hot sunshine, and radiant leaves tend to be yellow and dry。
