If the seed sown directly be used for aircraft, can easily be dispersed by the wind to the lower-lying areas or birds, rats eat, but to seed wearing a “smart clothes”, very different result. Recently, the Chinese Academy of Sciences, Lanzhou compounds other units to complete the “aerial sowing seeds of Tengger Desert Great grain and plant growth of new technology research” project, approved by the Inner Mongolia Autonomous Region Science and Technology Department of the identification of relevant experts. Experts believe that the technology is mature, low cost and effectiveness of significant aerial sowing in Inner Mongolia Tengger Desert Sand has made breakthrough progress in afforestation, has reached international advanced level, the proposed large-scale popularization.
The technology to environmentally friendly adhesives, inorganic and organic fertilizer, plant cellulose, water retaining agent such as raw materials, and selected a large grain of aerial sowing seeds of optimum conditions of preparation, shows five characteristics: First, an increase of seed weight to avoid seed displacement, so that aerial sowing seeds in the upper windward slopes of the normal germination and growth; Second, a coating solution conflicts with the damage, and germination in the dry state is very hard, and in the case of 10 mm effective rainfall collapse timely, ensure effective germination; third seed formulated with high water absorbing resin, it can fully absorb the moisture, the seeds need to grow and meet the water requirements; Fourth, adding organic and inorganic fertilizers meet the plant growth the necessary nutrients for plant growth and provide a microenvironment late; the five major grains in the seed, before adding the repellent at the same time drying the “rigid”, so that the seeds from birds eat rats, Alashan in western Inner Mongolia Autonomous Region annual rainfall of 60 ~ 250 mm, Badain Jaran Desert, Ulan Buh Desert, Tengger desert run through. Alashan forest system from 1984 fixing afforestation by aerial seeding experiments should further expand the broadcast area for the past 2 years with a large grain of seed technology for the 12,500 acres of aerial seeding, the seeds of the technology not only to prevent displacement and harm birds rats and aerial sowing of seed can 5m high sand dunes in the upper part of the normal germination in the growth of seedling area of 78%, 34% higher than the control area. This will help low-intensive site conditions of aerial seeding dune fixation, with special significance.
