    Abstract
    合理施用钙肥是提高蜜橘品质和产量的关键栽培措施之一.通过2 a的田间试验,比较了不施钙肥(CK)、施石灰(L)和施贝壳粉(S)对蜜橘品质和产量的影响.结果表明:与CK相比,L和S处理下蜜橘的含糖度分别提高了13.33％～19.80％ 和18.10％～26.73％,含钙量分别提高了7.70％～7.76％ 和10.82％～10.88％,产量分别增加了4.91％～23.99％ 和9.56％～27.47％.虽然S处理下蜜橘的品质和产量略高于L处理,但增幅均不显著(P>0.05).相关分析表明,蜜橘的含钙量与产量和经济产值存在密切关系(P<0.01).因此,在红壤中施用贝壳源钙肥可增加蜜橘的含钙量,进而显著提高蜜橘的产量和产值.

    • 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

    【要点】：本研究发现施用贝壳源钙肥可显著提高蜜橘的含钙量、含糖度及产量，是提升蜜橘品质与产量的有效方法。
    

    【方法】：通过2年的田间试验对比分析不施钙肥、施石灰和施贝壳粉三种处理对蜜橘品质和产量的影响。
    

    【实验】：实验在田间进行，数据集名称未提及，结果显示施用贝壳粉的蜜橘含糖度和含钙量提高，产量增加，与施用石灰相比虽效果略优但无显著差异，且蜜橘含钙量与产量及经济产值密切相关。
