农业生产中轮作可持续性的研究进展
NONGMIN ZHIFUZHIYOU YUEKAN（2017）
Abstract
近年来许多研究指出,轮作可以在增加粮食产量的基础上保持或者提高土壤有机质含量,实现可持续生产.土壤有机质是土壤中含有碳、氮的组成和结构不均的有机化合物,其是表征土壤质量的重要指标,影响着土壤中的各个生态过程,对土壤多种理化性质都有影响,其主要来源为土壤中的动植物残体和有机肥料.有机质含量丰富的土壤中营养元素不易流失、利用率较高,微生物活动旺盛,利于作物生长和环境保护.

- 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
