甜菜在田间生长的早期生产率与叶子接收的太阳辐射量成正比例。大量试验证明,甜菜最终产量与其一生中绿叶接收的太阳辐射量成正比。据Broom′s Baarn试验站的播期及遮光试验指出,决定产糖量因子是绿叶接收太阳的辐射量,遮光的甜菜产糖量3—8吨/公顷,不遮光的甜菜产糖量8.5—12吨/公顷。我们的任务就是要保证甜菜有健状的绿叶来接收更多的
The early productivity of sugar beet growing in the field is directly proportional to the amount of solar radiation the leaf receives. Numerous experiments show that the final yield of sugar beet is proportional to the amount of solar radiation received by the greenery throughout its lifetime. According to the sowing dates and shading tests at Broom’s Baarn Station, it is determined that the sugar content is the amount of radiation received by the greenery in the sun, the beet sugar content of shading is 3-8 tons / ha, the sugar content of non-shading sugar beet is 8.5- 12 tons / hectare. Our job is to make sure the beets have the gnarly green leaves to receive more
