不同覆盖物对小叶榄仁种子出苗的影响

Effects of different coverage on seedling emergence of Teminalia mantaly H.Perrier

为寻找较好的播种覆盖物,提高播种出苗率和育苗灌溉节水,在海南海口对小叶榄仁种子大田育苗进行不同的播种覆盖物试验,分析不同播种覆盖物对播种出苗率的影响。结果表明:不同覆盖物处理下小叶榄仁种子出苗率差异显著,影响出苗率大小的处理依次是A2、A1、A3、A4、A5,出苗率分别为76%、68%、62%、54%、52%。同时,该研究还对不同覆盖物的5种处理的最早发芽时间进行排序:A2(12d)>A4(13d)>A1(15d)>A3(16d)>A5(18d)。

A field experiment was conducted to explore better coverage in seedling emergence of Teminalia man- taly H.Perrier in Haikou of Hainan province,five kinds of coverage method were designed in field experiment. Results showed that there were significant different in Teminalia mantaly H.Perrier seedling emergence and soil evaporation in different kinds of coverage,the seedling emergence rate was 76%,68%,62%,54%,52% respectively, which from test A2, test A1, test A3 test A4, test A5. Meanwhile, the earlirest time of germination was sorted from 5 different covering treatments in the study. The order of the earlirest time of germination was test A2(12days). A4(13days). A1(15days). A3(16days). A5(18days).
