研究不同留桩高度对再生高粱二季产量的影响,结果表明留桩高度与再生高粱二季产量呈显著负相关,与再生高粱的生育期长短也呈负相关,即再生季高粱二季产量和生育期长短随留桩高度的增加而递减。
The results showed that there was a significant negative correlation between the pile height and the second-season yield of regenerated sorghum and negatively correlated with the growth period of regenerated sorghum, that is, the second-quarter yield and growth period of sorghum during the regeneration season With the pile height increases and decreases.
