Annual net primary productivity (NPP) of terrestrial vegetation is the net amount of carbonfixed by plants through photosynthesis in one year.
陆地植被的年净第一性生产力是植物每年通过光合作用所固定的碳总量。

The photorespiration of C3 plants may consume 25% of the carbonfixed by photosynthesis, so engineering photorespiration could improve photosynthesis.
C3植物光呼吸可消耗25%光合产物， 故合理改良光呼吸可望提高植物的光合效率。

Gas and carbonfixed char combining burning, strengthening the burning, reached full kindle, clean burning fuel purpose, improve the combustion efficiency.
