Other claims from this paper (8)
- Intervention effect Higher planting density treatment 120 cm×45-50 cm made tobacco plants grow faster than 120 cm×60-65 cm in the later vegetative period
- Intervention effect Higher planting density increased tobacco leaf yield
- Intervention effect Higher planting density did not increase tobacco leaf value correspondingly
- Intervention effect Ratio of total sugar to nicotine and total nitrogen and nicotine increased as plant density declined
- Intervention effect Differences in contents between total sugar and reducing sugar, total nitrogen and nicotine decreased as plant density declined
- Intervention effect Petroleum ether extraction, volatile acid and volatile bases decreased as plant density declined
- Intervention effect The changing rule of polyphenols and K contents with plant density was not obvious
- Recommendation The authors recommend a planting density of 120 cm×55-60 cm for KRK26 tobacco in the Yuxi area
