primary production

基本解释

Testing earlier in the supply chain, near the point of primary production, might seem like the most advantageous approach.
早在供應鏈進行測試，靠近初級生産的點，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.
初級生産、加工、分發和銷售中良好的控制與操作，對安全食品的生産來說都必不可少。
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淨初級生産資源（這是由植物組織光郃作用所産生的）。雖然這已經很多，但是還沒有達到用盡的地步。
