Background technique
Sacsaoul platymiscium belongs to Li Ke, and the whole world shares 11 kinds, is mainly distributed on the vast desert area in Mediterranean to the Central Asia,
It is grown on moving dunes, semifixed dune, salinized soil and conglomerate re servoir.There are two types of China, sacsaoul (Haloxylon
) and haloxylon persicum (H.persicum) ammodendorn.Distribution area of the sacsaoul platymiscium in China about accounts for the total face in China desert
Long-pending 9%.Sacsaoul is mainly distributed on the desert and half famine of the provinces such as Xinjiang, the Inner Mongol, Qinghai, Gansu and the Ningxia in northwest China portion
Unconcerned area, and haloxylon persicum is only distributed in In The North of Xinjiang.Sacsaoul is more general in northwest China arid, half-desert, Desert Area distribution
Time, it is mainly grown on moving dunes, semifixed dune, salinized soil and conglomerate re servoir, is the fine tree species checked winds and fixed drifting sand.It adapts to
Property it is strong, growth rapidly, with cold-resistant, drought-enduring, heat-resisting, saline-alkali tolerant, weatherproof, resistance to soil depletion unique property.Well developed root system,
Distribution is wide and deep.Biomass is high, and material is hard, and firepower is strong when burning, has the title of " desert coal living ", is good energy forest tree
Kind.Current year spray is excellent feed, is Eyjina main woody feed tree species.It is also the parasitism of " desert ginseng " Herba Cistanches
Plant.However, Haloxylon plant resources were once seriously destroyed because of human factor and environmental degradation, it is once in Critical Condition,
It is listed in country three-level protective plant in imminent danger.So accelerating the recovery of sacsaoul platymiscium woods and construction work has become China
The important topic of northwest ecological construction.
Seed is the starting point of the history of life, and is the terminal of the history of life.For seed plant, seed is the object of its breeding
Matter basis.It assigns vegetation and restores after by nature or human interference and regenerated basis simultaneously.Seed production (Fruiting Ability)
It is a key property of sexual propagation, selection intensity is directly proportional to setting percentage.Fruiting Ability height then can provide a large amount of discrepant
Individual provides larger chance for next-generation successfully procreation.Therefore, the seed production of sacsaoul platymiscium is studied, it appears extremely important.
