The constant development in the agricultural industry led to the need for a standardized communication system for various agricultural equipment. Agricultural equipment standardization first began in Germany in 1988 under the control of Verband Deutscher Maschinen- und Anlagenbau e.V. (VDMA), which resulted in a national standard DIN9684. The development toward agricultural standardization led to the creation of an international ISO-based standard, ISO 11783.

生猪产能去化幅度可观，猪价反转预期不断强化。养猪亏损严重且多数已持续半年以上，真实产能出清幅度可观，国家统计局数据来看，推算自2021年6月高点以来持续数月下降，累计下降幅度8%；涌益数据显示其样本能繁母猪存栏从去年6月至今年连续环比下降，累计去化程度已超10%。我们认为随能繁存栏变化带来的生猪出栏拐点向下，养猪板块供需有望从偏松逐步向偏紧改善，生猪价格反转向上可期，生猪板块周期投资逻辑不变。

In recent times, high emphasis has been laid on the adverse effects of conventional agriculture on the environment. Some of these concerns include depletion of natural resources, misuse of synthetic chemical inputs into the soil, and contamination of water resources. With the excessive agricultural activities over the land, land fertility globally has declined. To meet the growing global food demand with the increasing population, which is expected to reach 9.74 billion by 2050, alternative and safer ways of growing crops has been worked upon that utilize less space and are more reliable and environment friendly. This has led to a great rise in alternative production systems within both small growers and large-scale commercial productions.
