The trunk is straight, the bark of 3-4 m below is dark brown, the scale is deep split, the needle leaves are a bundle of 2 needles, the trunk is rigid and is usually twisted slightly, and the tip is sharp. The male and female plants are of the same strain, the male ball flower is oval and yellow, and the male ball flower is gathered at the lower part of the current-year branch; the female spheroids are spherical or oval, and purple brown. The cones are long ovoid. The scaly shield is in an oblique square shape and has longitudinal ridges and transverse ridges, and the scaly umbilicus is in a tumor-shaped protrusion. The seeds are small, have different colors of yellow, brown and dark brown, and are planted with the pterygoid.

2) Preparing the composite particles: taking the carbon nanospheres, adding copper carbonate powder, and grinding for 20min, wherein the mass ratio is 1: 1, dispersing for 20min by using 25KHz ultrasonic waves, loading into a graphite crucible, carrying out heat treatment for 1h in a vacuum sintering furnace at 1700 ℃ and 0.10MPa, and cooling to room temperature to obtain composite particles; the copper carbonate is decomposed into copper oxide at high temperature, and the carbon nanospheres generate ordered graphite carbon at high temperature, and the pore diameter of the carbon nanospheres is reduced, so that the copper oxide is wrapped or bonded on the carbon nanoparticles, and the dispersibility of the copper oxide is improved.
Dispersing the prepared composite particles in an aqueous polyurethane adhesive according to the proportion of 156g/L, and then adding 3kg/cm2Is uniformly sprayed on the inner side wall of the seedling raising pot under the pressure of the spraying amplitude.
The carbon nano-particles have good dispersion stability, the composite particles obtained by compounding the carbon nano-particles with copper oxide also show good dispersibility in a water-based polyurethane adhesive, and the composite particles are uniformly sprayed on the inner wall of a seedling raising pot under the high-pressure action in the spraying process for chemical root control, and can not generate side effect on seedlings due to high concentration of local copper oxide.
The invention has the beneficial effects that:
1. the cultivation facility can shrink the seedling cultivation facility by shortening the lengths of the support rod and the support arms at the early stage of germination of the cultivated seedlings so as to reduce the space occupied by the shrinking seedling cultivation facility, and can expand the seedling cultivation facility by extending the lengths of the support rod and the support arms in accordance with the actual growth requirements of the seedlings in the growth process of the seedlings so as to adjust the growth space of the seedlings and promote the growth of the seedlings of pinus sylvestris.
2. According to the invention, through the second air hole, the air pruning of the lateral roots can be realized, when the root system of the pinus sylvestris seedling grows outwards and downwards and contacts with air, the root tip stops growing, countless times of new roots germinate at the rear part of the root tip and continue to grow outwards and downwards, the number of short and thick lateral roots is greatly increased, the lateral roots are short and thick in shape, a winding packing is not formed, only the soil stump needs to be taken out from the inner pot body when the pinus sylvestris seedling leaves the garden, and the seedling lifting is convenient.
