不同播种时期对酸枣仁出苗及生长的影响

Effects on Seedling Emergence and Growth of Jujube Seed During Different Sowing Periods

以野生酸枣种子的种仁为试验材料,研究不同播种时期对酸枣出苗及生长的影响。结果表明,5月16日和5月6日播种出苗率最高,分别为89.61%和87.19%,显著高于4月26日的处理,极显著高于其他3个处理。5月6日播种的种苗长势最强,各生长指标最高,地径可达7.59 mm;其次是4月26日的处理。5月16日播种的种苗长势最弱,地径仅为5.80 mm,极显著低于其他5个处理。综合酸枣出苗及生长指标,酸枣育苗最佳播期为5月6日,其次为4月26日,建议当地酸枣育苗在4月下旬至5月上旬播种。

The effects of different sowing periods on seedling emergence and growth of wild jujube seed in Qingyang City were studied.The results showed that the highest seedling emergence rate was 89.61%on May 16 and 87.19%on May 6,which was significantly higher than that on April 26 and extremely significantly higher than the other three treatments.The planting date on May 6 showed the strongest growth with the highest growth index and ground diameter of 7.59 mm,followed by the treatment on April 26,while the planting date on May 16 showed the weakest growth with ground diameter of 5.8 mm,which was significantly lower than the other 5 treatments.According to the seedling emergence and growth indexes of jujube seed,the best sowing date for jujube seed cultivation in the experiment is May 6,followed by April 26.It is suggested that the local jujube seed cultivation should be sown from late April to early May.
