primary production

基本解釋

Testing earlier in the supply chain, near the point of primary production, might seem like the most advantageous approach.
早在供應(yīng)鏈進(jìn)行測(cè)試，靠近初級(jí)生產(chǎn)的點(diǎn)，似乎是最有利的辦法。
Good controls and practices during primary production, processing, distribution and sale are all essential to the production of safe food.
初級(jí)生產(chǎn)、加工、分發(fā)和銷售中良好的控制與操作，對(duì)安全食品的生產(chǎn)來說都必不可少。
Mankind appropriates about a quarter of what is known as the net primary production of the Earth (this is the plant tissue created by photosynthesis)—a lot, but hardly near the point of exhaustion.
人類僅利用了地球大約四分之一凈初級(jí)生產(chǎn)資源（這是由植物組織光合作用所產(chǎn)生的）。雖然這已經(jīng)很多，但是還沒有達(dá)到用盡的地步。

初級(jí)生產(chǎn)者
Environmental changes in global scales, such as increase of UVR, elevated CO2 concentration, ocean acidification and global warming, due to human activities can affect physiological processes and primary production in aquatic environments, and eventually influence ecosystems.
人類活動(dòng)導(dǎo)致的全球性環(huán)境變化（如陽光UV-B輻射增加、CO2濃度升高、海洋酸化及全球變暖等）,會(huì)影響水域初級(jí)生產(chǎn)者藻類的生理代謝,進(jìn)而影響生態(tài)系統(tǒng)的各種過程及生態(tài)平衡。
