五十年代山田等人从水稻栽培角度开始研究施 CO_1效果以来,松岛省三等人探讨了水稻不同生育时期施 CO_2效果,证明了显著的促进生长发育、增产效果。国外的研究表明,水稻幼苗期生长比较适宜的 CO_2浓度为900PPm 左右。本试验从实际栽培角度了解本地区苗期棚内 CO_2浓度日变化动态,探讨水稻不同品种、不周肥、密条件下施 CO_2效果。 In the 1950s, Yamada et al. Studied the effects of CO_ 1 from the perspective of rice cultivation. Three people from Songdo Island discussed the effects of applying CO_2 at different growth stages of rice, and proved that they significantly promote the growth and yield. Foreign studies have shown that the more appropriate growth of rice seedling CO 2 concentration of about 900PPm. In this experiment, the diurnal variation of CO 2 concentration in the greenhouse was studied from the perspective of practical cultivation, and the effect of CO 2 in different varieties of rice, non-weekly fertilizer and close conditions was discussed.
