Abstract


In this paper, a newly developed solid water, to study the effect of the laws of its release and seedlings , timeliness and slow release angle from moisture , aims to explore soil moisture drought in arid and semi -arid regions , and new ways to reduce water stress , effectively guide the promotion and application of solid water for afforestation in arid . Properties of the water from the solid and seedling effects and use solid water Afforestation applications three aspects were studied. The results show that : (1) simulated natural conditions , the same section on different amount of solid water treatment pot (no seedlings ) test results : solid water release pattern in the sand , the use of solid water the timeliness role in maintaining soil moisture and solid water release rate and meteorological factors . ( 2) under the conditions of a natural analog , different drought measures to deal with the potted plants ( seedlings ) test results show that : ( 1 ) solid water treatment 1.0 , the role of of 0.75kg processing and on film processing drought best , seedling survival longest control , film and solid water 0.25kg deal with the worst drought the role of seedling survival shortest ; the ② drought afforestation measures solid water treatment in the role of potted seedlings soil moisture significantly better than other treatments . ( 3 ) The the solid water field afforestation and road greening in the application test results show that : the solid water to maintain the moisture needed for growth of the supply of seedlings , which greatly improved the survival rate of afforestation , preservation rate and the biomass of the aerial parts of seedlings . According to the release pattern of solid water in the sand , no other water sources added , Ed Meyer \moisture content more 79.61 ~ 126.44g ( water content of the soil volume was 1.7 ~ 2.9%) , can maintain the normal growth of plants afforestation .
