The invention discloses a method for transforming the artificial young forest of western Sichuan subalpine low-efficiency picea asperata. On the cutover land of a western Sichuan subalpine forest region, a large area of artificial pure forest mainly comprising picea asperata is built, however, because nurturing measures are ineffective and shrub and broad-leaf pioneer tree species intrude into the artificial young forest, dense shrubs, poorer ventilation and insufficient illumination in the forest are caused to result in the conditions of high death rate, slow growth and difficult forest stand updating of trees of the artificial young forest. According to the invention, by adoption of the technical means of thinning, light-transmitting nurturing, pruning, removal of weeds and shrubs in the range being 0.5m beyond the crown projection of target tree species, after-culture of four-year-old seedlings of the picea asperata, nursery stock nurturing, forest stand management and the like, the forest stand structure, species composition and forest stand site conditions are improved, and the survival and growth of the trees are promoted obviously. The method disclosed by the invention has the advantage of improving the forest stand quality and economic benefits of the artificial young forest of the low-efficiency picea asperata and is likely to have a broad application prospect in the transformation of the western Sichuan subalpine low-efficiency artificial young forest.

The invention relates to a chemical enhanced phytoremediation method of polycyclic aromatic hydrocarbon-cadmium pollution soil, belonging to the field of soil pollution regulation; the method comprises the following steps: (A) the content of cadmium, polycyclic aromatic hydrocarbon, phenanthrene and pyrene in the soil is measured, and willow sowing is carried out; (B) chemical enhancer constitutedby ethyl lactate and ethylene diamine tetraacetic acid is added after the willow is sewed for four months.

The invention provides a method for culturing Guangdong flowering cabbage. The Guangdong flowering cabbage has a longer seedling period, so a culturing method which first raises seedlings, and then transplants and plants is adopted mostly in the production to improve land use capability. The seedlings of the Guangdong flowering cabbage are in a tap root system, and have few fibrous roots, so roots of the Guangdong flowering cabbage cannot sufficiently absorb nutrition and moisture, the Guangdong flowering cabbage grows slowly after transplanting and planting, does not resist water logging or root diseases, and does not have high yield. In the method, seeds of the Guangdong flowering cabbage are accelerated to germinate before the seeds are sown; when then length of the germinated root tip of the Guangdong flowering cabbage reaches 0.5 to 1mm, the seeds falling down from a 70-degree-slope hot iron plate at the temperature of between 100 and 130 DEG C to achieve the aim of burning the root tips, so that the sown Guangdong flowering cabbage has short main root and many fibrous roots, survives fast after transplanting and planting, and has vigorous growth, disease resistance and yield improved by 15 to 20 percent.
