    Abstract
    为筛选出适合西北旱作区种植的马铃薯品种,本文对10个马铃薯新品种的田间性状及产量开展了比较试验.结果表明,10个参试马铃薯品种出苗率、叶面积指数和冠层温度差异不显著.参试品种株高为87.6～123.4 cm,以青薯9号株高最高;主茎数为1.6～3.2个,陇薯13号、定薯3号、定薯4号、天薯12号、青薯9号、丽薯7号、庄薯3号与对照陇薯6号之间主茎个数差异性不显著.经过田间抗病性统计,青薯9号抗晚疫病、抗早疫病最强,定薯3号、陇薯13号、陇薯14号和定薯4号次之,陇薯6号和丽薯7号抗病性最差.青薯9号产量最高,为72107.1 kg/hm2,较对照陇薯6号增产43.9％.结合田间各性状及产量构成情况,青薯9号、陇薯14号、陇薯13号、定薯3号、定薯4号和天薯11号田间表现较好、产量较高、综合性状好,可以在西北旱作区大面积种植.

    • Pretraining has recently greatly promoted the development of natural language processing (NLP)
    • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
    • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
    • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
    • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
