摘  要:
针对目前浅海海草床修复方法,生境恢复法投入少、代价低,但周期长;移植法成活率高,但是对海草床又破坏作用现象,研制了播深、粒距和行距根据需要可调的浅海海底植被修复播种机;本文对浅海海底植被修复播种机的排种均匀性、分布均匀性进行试验,对浅海海底植被修复播种机的开沟性能以及覆盖性能进行试验。试验结果表明:排种均匀性检测最大变异系数为18.5%,小于国家要求45%,达到试验要求;开沟深度最深处为5cm,最浅处为1cm,平均深度为2.9cm,覆盖良好,覆盖率达到95%以上,技术性能参数均达到了技术指标要求。

摘  要:
Aiming at shallow seagrass beds, repair methods, habitat restoration method a small investment, the price is low, but the cycle is long; high survival rate of transplantation, but on the seagrass beds and damaging phenomenon, developed sowing depth, grain distance and line spacing according to need adjustable shallow water seabed vegetation restoration planter; Based on the shallow seabed vegetation restoration planter seeding uniformity, uniformity test, ditching performance of the shallow seabed vegetation restoration planter covering the performance test. The results showed that: Seeding uniformity maximum coefficient of variation of 18.5%, 45% less than the national requirements, meets the test requirements; ditching the depth of most of the depths to 5cm the most shallow cm, an average depth of 2.9cm, good coverage more than 95% coverage, and technical performance parameters have reached the technical requirements.
