Abstract
The invention relates to an improved matrix for ex situ conservation of populus euphratica. The improved matrix comprises a probiotic organic fertilizer, turfy soil and aeolian sandy soil at a weight ratio of (0.2-1.5):(2-4.5):(4-10); the improved matrix is used for transplanting and replacing planting soil in an ex situ conservation process of the populus euphratica; the probiotic organic fertilizer comprises a water-retaining agent, a biological bacterial manure, a plant fiber, an urban organic waste compost or a mixture of several kinds of the water-retaining agent, the biological bacterial manure, the plant fiber and the urban organic waste compost. With the adoption of the improved matrix for the ex situ conservation, the fertilizer efficiency and the activity of desert soil can be improved effectively; a survival rate of the populus euphratica is ensured; the populus euphratica can rapidly survive and restore to grow after transplantation. Moreover, the improved matrix achieves successful transplantation of the populus euphratica in an extreme continental arid climate environment.
Description
Technical field
The present invention relates to the in situ conservation matrix of a kind of trees, particularly relate to the in situ conservation matrix of the large tree of a kind of diversiform-leaved poplar.
Background technology
Diversiform-leaved poplar (formal name used at school: Populus euphratica Oliv.), claim again poon (< < Chinese book > >), hero tree, different leaf diversiform-leaved poplar, cotton tree, water paulownia, three leaf trees, it is a kind of plant of Salicaceae Populus diversiform-leaved poplar subgenus, there is heat resistanceheat resistant, cold-resistant, anti-blown sand, anti-saline and alkaline, drought resisting and anti-barren characteristic, have " raw and thousand not dead; dead and do not fall for thousand, fall and thousand immortal " good reputation.
Diversiform-leaved poplar is unique primary arbor species that are grown in desert, and very precious, can with have the ginkgo of the title of " plant living fossil " to compare favourably, diversiform-leaved poplar is Tethys composition, the ancient seeds of the 3rd century remnants, just existence on earth before more than 6,000 ten thousand years.
Diversiform-leaved poplar vertical root can reach underground 20m; lateral root can reach nearly hundred meters; foundation portion capillary Gent is not few; natural modes of reproduction be take root germinating seedling as main; lifting cannot be with Tu Tuo, and therefore, diversiform-leaved poplar big tree transplanting is difficulty very; all the time, the in situ conservation of the large tree of diversiform-leaved poplar is all the global problem in the wooden field of name.
Summary of the invention
The object of the invention is to propose a kind of in situ conservation matrix that can effectively improve and guarantee the large tree of diversiform-leaved poplar of survival rate.
For achieving the above object; the invention provides the improvement matrix of the large tree in situ conservation of a kind of diversiform-leaved poplar; described improvement matrix comprises that weight ratio is probiotic bacterium fertilizer, turfy soil and the aeolian sandy soil of 0.2～1.5:2～4.5:4～10; described improvement matrix is for the replacing planting soil of planting of the large tree in situ conservation of diversiform-leaved poplar process, and described probiotic bacterium fertilizer comprises water-holding agent, bio-bacterial manure, vegetable fibre, city organic castoff compost or any several mixture in them.
Preferably, described probiotic bacterium fertilizer comprises that weight ratio is water-holding agent, bio-bacterial manure, vegetable fibre and the city organic castoff compost of 1:20～50:50～80:200～300.
More preferably, described water-holding agent is grafting modified of starch type.
Preferably, described bio-bacterial manure comprises actinomycetes, vinelandii, silicate bacteria, photosynthetic bacteria or any several mixed strains in them.
Further, in described bio-bacterial manure, effectively bacterial content is not less than 200,000,000/gram.
Preferably, described vegetable fibre is selected from xylon, rice straw or wheat stalk.
Preferably, described city organic castoff compost is selected from the finished product fertilizer after garden waste compost, consumer garbage compost or sanitary sewage disposal factory sludge composting.
Based on technique scheme, advantage of the present invention is:
By the improvement matrix of in situ conservation of the present invention, can effectively increase the fertilizer efficiency of desert soil with active, guarantee the surviving rate of diversiform-leaved poplar, and make diversiform-leaved poplar after transplanting, can survive rapidly and recover growth.Further, the invention solves in extreme continent dry climate environment the large global problem of successfully transplanting of setting of diversiform-leaved poplar.
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
Embodiment 1:
The improvement matrix of the large tree in situ conservation of diversiform-leaved poplar of the present invention is changed planting soil while being mainly used in the large tree of diversiform-leaved poplar to plant in the planting hole of in situ conservation.Improvement matrix of the present invention comprises that weight ratio is probiotic bacterium fertilizer, turfy soil and the aeolian sandy soil of 0.2～1.5:2～4.5:4～10, and in the present embodiment, aforementioned proportion is 0.2:2:4; Wherein, described probiotic bacterium fertilizer comprises water-holding agent, bio-bacterial manure, vegetable fibre, city organic castoff compost or any several mixture in them, in the specific implementation, can adopt easily the mixture of bio-bacterial manure and city organic castoff compost; Preferably, described probiotic bacterium fertilizer comprises that weight ratio is water-holding agent, bio-bacterial manure, vegetable fibre and the city organic castoff compost of 1:20～50:50～80:200～300, and in the present embodiment, this ratio is preferably 1:20:50:200.Improvement matrix of the present invention is mainly used in the replacing planting soil of planting in the large tree in situ conservation of diversiform-leaved poplar process, certainly, is understood that to those skilled in the art, also can be by the in situ conservation planting soil of the present invention's application other plant.
Preferably, water-holding agent of the present invention is grafting modified of starch type; Described bio-bacterial manure comprises actinomycetes, vinelandii, silicate bacteria, photosynthetic bacteria or several mixed strains arbitrarily in them, and preferably, wherein effectively bacterial content is not less than 200,000,000/gram.
Vegetable fibre of the present invention is selected from xylon, rice straw or wheat stalk.Described city organic castoff compost is selected from the finished product fertilizer after garden waste compost, consumer garbage compost or sanitary sewage disposal factory sludge composting.
The performance of the present embodiment is:
